I run my server, my computer, and my partner's computer over 10Gb currently. Mikrotik switch and sfp+ cards with fiber modules in each machine. It's so overkill, but it's great for my lack of patience in massive data transfers.
I have been doing 1gig but recently have been transitioning to move things over 10 gig. Installed 10gig adapter on the pfsense machine and the ISP router already. I have been looking for a switch that serves the purpose and this one looks promising. I want to do 10gig on the nas, proxmox server and the pfsense machine.
I run 10gig to my file server and router (in the same rack) and to my office, but I do want to replace the cat6 run to my office because those rj45 transceivers get hot.
Just to demystify this topic a little bit (because it's less complex than people think): (modern) Ethernet fundamentally just needs 8 wires to work, so any 8-lead cable can run any speed in theory. They are all wired the same electrically. What determines if you can practically run a high speed though is the signal quality - which is mostly a function of the length of the cable, but also the quality and Em noise separation. The higher speed, the cleaner the signal needs to be - so either better cabling, or shorter distance. In a typical home with relatively short wiring you can usually run much higher speeds than the cable is rated for, because the cables rating is usually designed around 100m or so. Thus, if you have a 10 or 20m cable you can run it far "above spec" without issue, because the short length more than compensates for the worse cable quality. If you run a higher speed than the signal quality can handle you will get packet loss. That "wall" hits pretty fast, so it tends to work either flawlessly or terribly (or not at all more likely). I would always recommend checking packetloss under stress when running a cable out of spec. It tends to be be fairly obvious if it's fine or not. TLDR: If you have old cables in your home, you should test them before upgrading for higher speed. Chances are you won't have to change them - or at worst, maybe only your longest cable run.
Not sure if mentioned before but the Copper SFP+ modules run hot and I would not recommend sitting them next to each other due to the heat they put out.
On short to medium runs usually cat5e isn't an issue with throughput as much as it is with it being damaged over the years or getting interference from other systems. Many people have Cat5e running in a industrial or somewhat hostile environment and they will not have a good time with 10GBE.
A lesson I recently learned is that SFP+ modules negotiate 2 speeds - between the switch and the module, and between the module and the PC in your case. The link speed shown in UniFi is only the former…it won’t show the link speed between the switch and the PC. You can only verify the links on either end of the module.
Then why did it auto-negotiate 1G on his machine that also reported 1G? I would think it should have shown auto-negotiated a 10G for the switch with his PC reported connected at 1G.
Don't forget, Windows file copy is only a single thread process so the numbers won't be that fast. Linus Tech Tips ran into the same problem when upgrading their network.
NiTeHaWKnz... Just remember that depends on the SMB version you are using... SMB 3.0+ can be multi-threaded and even multi-adapter using SMB-MultiChannel. You can check this looking at powershell with get-smbconnection and get-smbmultichannelconnection. In my case I have a dedicated 3.1.1 server utilizing 4 40Gb nics and the storage to back it and I am able to read at about 12 GB/s or ~48Gb/s.
The copy is working just fine and can hit 10Gbps as he saw in the first few seconds. The problem is the drive speed. It was able to go full speed because it was essentially filling up server RAM as a write cache. Once that cache is full, then you are only getting raw write performance.
This is no longer true as of SMBv3 and the CIFS version that supports the multithreaded CIFS implementation. This is recent (last 5 years or so) but has been present on Windows Server and Client OS since Windows 8.1 was released.
Over 1G network sometime you have to "Hard code" the speed in both side. In a core network, we'll never use auto negotiate, we must hard code the speed at both side, it will more stable and will not suddent drop to other speed.
My house was built in 1997 before the cat 5e spec was even a thing, and was wired with decent enough quality cat 5 (no "e") that I actually can get 10G over the ~30ft from my living room to the garage.
Cool project. On your auto-negotiation issues, I have heard that SFP+ to RJ45 modules can have issues negotiating 10G on Ubiquiti and is just better to set the desired speed manually.
The X540 intel 10gbit adapters are sometimes finicky. I use them for all of our production equipment and they work fairly well. Check your switch's stats on that port for CRC errors. That would tell you if it's clean.
That's awesome and gives me hope. I have a cat5e cable going up one side of my house, across the roof and down the other side. It is a 2 story house, so I think I may be coming close to that 55m, but at a guess, I think it's about 45m. This connects my 2 parts of my homelab, where I have rack servers sitting on a cupboard, and the other end to my office. I have wanted 10Gb, but always thought the cable wouldn't work so never tried, and don't really want to run another cable, though I have a whole spool of cat6 that I was gifted. Off to eBay to see if I can get some cheap 10Gb switches that support VLANS.
The SFP+ to RG45 converters are notoriously quirky and its no surprise that auto-negotiation doesn’t work reliably. Just set things to 10Gbe (like you did) and all should be well. You might alway want to play around with setting jumbo frames (9k MTU). It can make a huge difference in transfer speeds at 10Gbe, especially to/from windows which does single-threaded IO for most file transfers.
Yes it will... I test these things. It can't be recommended because of distance and interference issues, but yes you can. Hell, someone got 1 gig over barbed wire.
Cool. I know you said the cable is twisted all over the place, from attic to basement, but do you have a rough idea how long the run is that worked at 10G?
I used a cat5e for 10g that was 120' give or take a few feet. I used it for years. I needed a second connection is the same location so I ran a cat6a and used that for the 10g. I didn't notice any performance or speed difference between the cat5e or the cat6a, if it were serval hundred feet maybe. At 10g speed the real bottleneck is the machines you're transferring files between. CPU is a factor but the storage drives that files are moved from/to. As Tim did I assume the source drive was an M.2 sending to HDD you get fast transfer till the drive cache fills then you get drive speed. It's not just limited to the destination drive. If you're copying from an SSD to another machine with an M.2 the limit will be the read speed of the SSD for the transfer speed
That is awesome. I love to bust myths... I'm currently running 1 gig through telephone wire which happens to have 8 wires... Everyone even said its not possible because its litterly not shielded at all.. Paket loss is a bit higher, I would say wlan standards. But speed and everything is awesome. Love to see you manged 10gig with cat5... Sometimes it makes me think cable industry is a bit... Sketchy and never really tests their new standards...
Cat 5e isn't shielded (although you can get it that way), it uses twisted pairs. If your 8 conductor phone cable used twisted pairs, then you'd probably be fine as long as you wired the pairs up correctly.
What sort of "telephone" cable? Phone cable is 3 pair CAT3, which is rated for 10 Mb Ethernet for 100M. However, CAT3 is getting scarce these days, so people often use CAT5. Shielding has little to do with it, unless you're in a noisy environment.
my whole house is cat5e pure copper. I hit 10G no problems. I get about 777MB/Sec transferring to my Storage spaces 3 stripe 32KB, 64KB Allocation size in parity setup. Pure HDD Pool.
I jumped from an HP ProCurve 24-port directly to the 48-PoE-Pro, and couldn't be happier. I also added a fan inside to keep things quite cool. It's a powerful device, and can be chained to multiple copies of itself.
micro center... looks like what Frys used to be... I miss frys :( No micro center in the phoenix area :( I have to drive 6 hours to LA to go to Micro Center.
When I forget to some MAC address and a device drops off I dump my arp table to a text file. Maps ip to MAC and makes finding it easier. Has saved time at work and home.
Very exciting stuff. I have about 130ft run I need to do. All I have laying around is CAT6 and came across the same problem you did. Officially, MikroTik only supports SFP+ to RJ45 for 30 meter runs. The rest of my network is all Unifi, but unfortunately hard to get my hands on nearly ANYTHING 10 gig for a decent price. I even had to resort to ebay because Mikrotik devices are selling out fast. It's good to know that I'll be able to do something temporary until I can terminate my own fiber. By chance, do you know if LAG works with SFP+ 10 Gig? I can try to find a dual port 10 Gig PCIe card and just run 2 drops of cat 6 while I'm at it. That should get me up to 10Gig or higher speeds.
I just upgraded from a 50mbt fixed wireless solution to a 2gbt fiber service (Thank god after waiting 20 years for REAL internet here!!) so I'm looking to upgrade my infrastructure here in the house. Running Cat5e as well so may just use what's already here. I run a lot of stuff over wireless but all of my core services are on hard lines.
I was pleasantly surprised when Cat5 (non-E) in my walls did 2.5gbe. Unfortunately my little itx gaming rig doesn't have a 10gbe NIC like my server does.
ive run cat6a non-shielded cable and keystones. i have no 10gb equipment (yet), however i do have some long POE+ runs. wanted a thicker gauge wire to reduce heat generation, and future 10gb expansion. pulling cable sucks sometimes.
Yea Windows only use 1 thread. That being said it could also be the hdd which is out of caching. The moment the cache is empty, you rely on the actual disk speeds (read and write)
I also bought a Cat 5e to use with my four QSFPTEK SFPs, it's cheaper than what you use in your video, as you don't have much budget, but my computer-to-computer transfer speed is about 800 Mbits per second
Just my opinion, but if they ever have better /more conductive connectors than gold plated brass it'll boost more length meters. Silver plated is more conductive than standard the gold plated.
I don't know what you did with the cables to begin with. But if you put them in proper cable channels, then it would be easy to tape a new cable to the old one and pull it all the way back with the help of the old cable. No need to crawl in the attic... It could still work without a channel, but could snagg on something and if you stapled it, it obviously won't work at all.
I have upgraded some Weeks Ago (USW-Pro-24), but just my Server (DAC, its in the Rack with the switch) and my Desktop (Upstairs, RJ45). I wired the house with CAT7 cable when we bought it 8 years ago. I ain't got working full 10 Gbit at first try at my Desktop. I thought I messed up some shields at the Patch Panel, but it was a faulty (bought) CAT6A Cable wich connected the Desktop with the Patchpanel. Greets from Germany
When doing an iperf3 test, always test with a Linux machine at both ends. Gives you near wire speed, whereas Windows tends to limit you to 7 and change gbps. Apparently, WSL gives you slightly more, but it is still limited.
My workshop to my house is 10GbE using exterior grade MM Fiber, but I need to extend it to other parts of the house. I will probably connect my wife's office with 2.5GbE because that's better than WiFi at least.
10Gbe can be finnicky or resiliant... it purely depends on the adapter and its tolerance... the mac mini m1 10gbe interface is not resiliant at all and will try to hold a 10gbe until it gets noise then it just drops down to 1gbe and never recovers... whereas the newer mac studio 10gbe interface will recover and yield an effective higher rate... over the cat 5e that i have thats about a 50 ft run between 2 walls, mac studio gets sustained 6.5g up and 9g down, but the mac mini will only get 6 up / down until it hits noise and it drops to 1gb for ever until you reset the adapter or pull the network cable and reconnect... so a lot of the cat 5e performance has to do with how resiliant the nic and software is.
Thanks for your video! I have a 6cat in my flat, so maybe I will get even more than 8Gpbs. I use a UDM Pro and it has only one SPF+ LAN port, so I can just try to connect one of my PCs to it, but to connect a second one I have two troubles, first off all I need a 10Gbps switch, but I don't want to buy it right now, and the second problem is that my client PC workstation has no free 16/8 PCIe slots for a 10Gbps NIC, because one of them is used by GPU and second one by RIAD controller, haven't found yet a solution for a 10Gbps in x4 PCIe lane. But maybe in future I will change my motherboard to a newest, with a built in 10Gbps NIC, yeah, they are puting such speedy adapters to a "home" workstations. Best Regards!
If you get the correct SFP+ transceiver you would be able to have 802.3-bz with 2.5/5/10 Gbps speeds. On you Linux can you use `ethtool` to verify the speed.
I plan on running 10gig between my "high performance" NAS and my main PC. This NAS has all movies, games and hot storage for photo and video editing for me to offload most of my drives and hard drives away and use rundand drives. A lower performance NAS can store all "archived" stuff but yeah. For the rest, I'm probably going with 2.5gig or 1gig. Our fibre connection is "just" 1gig. Most of my devices don't support more than that and I think, for the current price and my situation, 10gig on scale is currently useless. To become useful, the price has to drop quite a bit more. Maybe, I use 2.5gig. Cable's not been any issues here. I think, my "weakest" cables are CAT6? So definitely capable of 10gig. And if I'm going to buy a home or built one, I'm definitely going to squeeze in the best, I can afford to future proof my home. Probably CAT8, as it's not too expensive anymore. But first, I need to wire up my current flat correctly and set up my cables properly. Currently, everything's a mess and I don't even have a good, central storage solution for the devices nor proper cable management... :D BUUUUUUUUUUUUUUT it works. I don't really know how and why but it works. And I'm not going to question it xD
I'm literally in the process of buying a condo and I discovered during inspection that all the phone jacks were wired with Cat5e, so I was already researching 10G over Cat5e when I saw this video. Excellent timing! I'm going to give it a shot after I move in.
I bought my condo 29 years ago and it was wired with CAT3 and daisy chained jack to jack, so not the greatest for Ethernet. However, when I got my cable modem, in the late 90s, my ISP actually ran cables in for me. I wanted the modem in my "office", which is at the opposite end of my unit from where the cable comes in. My ISP sent a 2 man crew who spent 3 hours fishing the cable up inside the wall between my living and bedrooms, along side an air duct, over my closet and bathroom ceilings and into my laundry room, where it crosses my ceiling, then down behind the water heater and through the wall into my office closet. While they did that, I had them pull in a couple of runs of CAT5 (5e wasn't available then). They even patched the drywall where they cut it. In addition, they put red "Data" tags on the coax.
i know this is kind of old, but cat 5e says it only supports 10Gb for really short distances (100ft or less) ... just saying this to make others that may watch this later that don't know this be aware since you mentioned you have cat5e ran all over in your attic and stuff and don't want people to think that if they run cat5e they will always get 10Gb especially if they need to run more than 100ft (33m). Anyone that is running a new network at home really should just make the jump to Cat6 since that is good for up to 55m... Cat6a is good for 100m according to the specs, but the cost just may not be worth it. The other option would be SPF+ using MMF OM3/OM4 if you really need some long runs but those SPF+ modules add $$. really for most situations, i would think that 2.5Gb is more than most would need for just normal type stuff (cat5e or Cat6 is more than sufficient), but if you transfer large files a lot and would really honestly benefit from the 10Gb performance then maybe going cat6 or Cat6a would be worth it when doing new runs. I just cannot get over the pricing of 10Gb switches. The Unifi 24XG can do it but it also doesn't have PoE. Their Enterprise 24 can only do 2.5 Gb on most ports. The Aggregation Switch from them has 10Gb for its ports but are all SPF+. For me the cost of going full 10Gb is just too much than going 1Gb with just some fast uplinks to different areas... then again, i also don't transfer large files on the regular so it fits my use case.
Not sure about those RJ45 SFP but with DAC, you need a SFP+ DAC and SFP+ connector to get the full speed. Using SFP cable on a SFP+ connector wont give you 10GB/s only 1GB. Learned that the hard way..
10 gig - does anything in the home use 10 gig. Computer to computer limited to the speed of the hard drive. OR SSD that 550MBs at the high end. Unless you RAID them but most home users do not raid hard drive or SSDs. Now anyone that renders videos would have a need for it. but yes the CAT5E cable should pass 10gig and most homes would have a low RF interference with the cable. Unless they have High power power lines. I have run into that before. We could run LED inside the house with just a coil of wire in the living room. but that was a rare find.
I've watched all your videos, you're an awesome dude. When that 10Gb connection kicked in, I think that's the first off-script, out-of-character I've ever seen you. Most the time, it seems more like you're reading from a script; this was more akin to the first time you ever had an orgasm and didn't know what was going on. Absolutely loved it brother Timothy, but thanks for not showing us your pants afterward.
I have a 3ft cat5(not E) cable that will auto detect to 10gbps. I use a 4ft cat 7 cable that I feel works better for the 10gb run though. I have not done tests to see if there is a physical limitation of the cat5 cable compared to new cables.
Tim, thanks so much for doing this test. I have a Ubiquiti US-16-XG UniFi 10G 16 port switch (12x SFP+ & 4x RJ45) on backorder and for RJ45, I have a bunch of CAT5e cables and nothing better, so I'm glad to see those will work for the time being. Because of cost, I was thinking of getting some used Mellanox CX311A 10Gig SFP+ cards + transceivers and fiber cables for my main PC, the Cisco server I have and two NAS's. Everything is in my office so all short runs.
10G BASET - most of the time the auto-negotiation does not work really well on "consumer" switch hardware also grounding on the CAT cables plays into the circumstances why it has troubles syncing to 10G properly
GBIC can't be good for this ...probably best to go with a native 10GbaseT type port. Also, should be checking packet error stats instead of throughput.
For short runs (like in a typical home) and low EM noise environments, Cat 5E is often enough. But, remember its cable distance, not human walking distance. Also following paths for power lines (ie: HVAC, kitchen, bathroom) can cause issues. Living near a TV or radio transmitter can also cause problems.
tl;dr I already know it works.. it is one of those things that are out of spec but do work in shorter distances. now should you run cat5e on a new network ? Like my fokin isp did when i wasnt looking? No. use dac cables for short distance, fiber for everything else ..ethernet when there is no other way.. will cheap-bastards-inc isp cabling do 10gig if I try? Yeah, it probably will.
I currently have a Ubiquiti 16 port Poe switch and I just purchased a Ubiquiti 24 Port Pro Poe switch. Do I need to do anything prior to unplugging the 16 port and installing the 24 port? I assume the 24 port switch will just pop up to adopt and I just go through adopting and it will work?
But will it be _stable_ and _reliable_ . Iperf and file copy might show you good numbers, but will you experience unexplained file copy stalls, or weird disconnections mid transfer etc...those "wth just happened" issues....how has it been since this video was uploaded?
So the limit is not the cat5e cable but the other hardware in your PCs like the slow spinning drives, which Synology uses in their nas so max speeds will be 500-600mbs no matter what. 10G is literally a pipe dream, pun intended.
I have the Aruba S2500-48P. 48 ports of gigabit POE and 4 SFP+ ports. I used Finisar 10gb SFP+ multimode modules with 10M of OM3 LC to LC fiber cable. Both worked great connecting the Aruba switch to my Mikrotik 10gb SPF+ switch.
Interesting. I use noctua fans in my home lab to keep it quiet so I can have the whole rack next to my monitors and desk. (No basement for me to stick it in anyway) for me a new run would be as easy as unplug and put in new cables because the only thing coming off the home lab is display cables and a kvm for my keyboard/mouse.. its kinda silly having a whole 48U rack next to you while gaming but you get used to it.
@Tim, to be sure you have a stable 10Gig. Best to check your Switchports on the switch. Look if they do not flap and you do not see any errors on those ports.
9:47 Uhg. DHCP on UniFi ... I have a machine on two separate VLANS, one for storage access, and one for everything else on the network. Half the time name resolution gives me the IP for the storage network and the other half of the time, it gives me the IP I actually want back.
The main difference between Cat 5e and Cat 6 cabling is signal attenuation. To get a specific bandwidth we need a minimum amount of signal to noise ratio (SNR) at the receiver, and the sender only has X amount of power it can deliver down the line. So more attenuation means a shorter distance is needed before the signal strength is insufficient to achieve the needed SNR. However, other factors can also effect SNR, so in more electrically noisy environments Cat 5e can be insufficient at lower distances. In general for home and even office use, Cat 5e can carry 10 Gb/s Ethernet for 20-30 meters without issue in most situations. However, not always. Cat 6 has thicker wires that gives the signal a bit more surface area to work with, effectively lowering attenuation. Also makes DC power distribution via PoE easier. Cat 6 is often also having a spacer that spaces out the 4 pairs from each other, reducing crosstalk and improving SNR a bit more. Some cables have a shield as well to protect the cable from external electromagnetic interference. Then there is also Cat 7 cable on the market, but the networking industry don't really use it yet. But it tends to have individually shielded twisted pairs, as well as a shield around all four pairs. And on top of that the different pairs use different amounts of turns/twists per unit of length, this is to reduce crosstalk even further. But in short, the things of importance is the signal to noise ratio at the receiver. Even just hand wiring some loose copper strands with minimal twisting can run 10 Gb/s Ethernet as well, though not particularly far.
@@wayland7150 The Cat rating of the cable doesn't really affect latency. But yes, Direct Attached Copper is lower latency than a pair of SFP to Ethernet converters. Mainly since Direct Attached Copper is literally as the name implies, the Tx differential pair going to the SFT port just gets routed straight over to the Rx pair on the other SFP port. Ie, no logic, nor any protocol processing. DAC cables though have signal buffers to ensure that the signal makes it over, but this adds almost no appreciable latency. Regular optical SFP modules work in the same fashion, just instead the signal buffering drives the light source, or reads the optical sensor on the other side.
@@wayland7150 The average person wouldn't notice the difference in latency. You're talking hundreds of microseconds. and there is no reason to bother with Cat7 for 10 Gbps, it's not even recognized as proper cabling standard either. Beyond Cat 6 it goes up to Cat8. Again there is no purpose for it for 10 Gbps.
@@todayonthebench There is a huge different in latency between CAT6 and DAC. Forget The Average Person because they can't tell the difference between 100meg and 1gbit so have no use for 10gbit. The exceptional people who do care would be very keen on low latency because in some applications that's the crucial factor like gaming.
@@wayland7150 Any latency differences in cables on the local network gets dwarfed by the latency of the internet at large. So for Gaming the local network cable delay isn't really going to have an effect on latency. The latency of cables only starts to matter when one deals with local network storage for database applications, or for clustered computing workloads. Not gaming.
Hi tray MeshCommander and Intel AT if You have Intel CPU on that serverbtw connect internal on mainboart nic to myour network/servers managment network and sewt ipv4 as static on that nic Inteel AT is good for simple tasks on remote server but have problems with iso boot por mause scrolling not work coreclyon server if run windows on that server. That is free solusion but security mebe is low if You turmed on Intel AT - that depeds what secure Your network is.
i would say on cat5e depends on quality of the cable, but i wouldnt use cat5e for 10gb, i know because cat5e on 1gb wams up when transferring a lot of data but nothing dangerous, but i dont know about 10gb how high, also cat5E has no shielding to protect it from outside influence like other cables(electric or network). you dont need to do holes, just pull the old cables while the new cable its attached to the other end. :) fiber doesnt heat up or is being influenced by outside sources. would go with cat 7 or 8 for an upgrade, prices are quite low for them so for future prof would recommend them, if you have less than 40m distance between connections you can go with cat 8 for future 40gb connections but isnt cheap
Would like to find a video (honestly havnt searched yet but will look) on a video for that iperf and windows 7 and unraid. I have 10g in both (and another in a win10pro machine) but not seeing decent speeds, could be the spinning rust not sure. But didn't notice a difference between the 10g and standard 1g....
Nice that you got the cat5e cable to work. How long are your runs of cat5e in your tests? You said it was up in your attic but what are we talking about? 20ft? 50ft? More? Thanks.
A few things to note. SFP+ to RJ45 transceivers are known to have tighter limitations on 10gb distance, and if not for the fact this is a switch you’re running on, would have been better to seek this functionality natively as there’s a bit of a heat problem. Good to see this worked out for you though. Cat5e is not rated for 10G, so you’re playing the cable lottery. You should get cat6A when you have the opportunity. Most devices will autonegotiate at 1G when they detect the signal quality of Cat5e. Typically, if you truly won the lottery, it will autonegotiate at 10G thinking it’s cat6 or 6a.
Excellent video Tim, BUT you failed to mention 1 CRUCIAL piece of information, how long is your CAT5e run? This is a question I have researched several times, and like you I saw varied answers. We desperately need to know HOW LONG THE CAT5e RUN IS?
my understanding renegotiation in switches, if you have 4 spf+ ports they are shared ports with the last 4 ports of the standard side of the switch, you use the either/or principle and not both...
Why don't you use much cheaper SFP+ NIC and DAC cable for a server located close to the switch? PS Don't forget to set MTU to something more than standard 1500 bytes, most modern NICs support 9000 and even more, this can increase your throughput and decrease CPU usage a lot.
Hi Tim. FYI. I had issues with my 10G connection to TrueNAS. I enabled Jumbo frames and Flow Control on my Unifi switch, 9000 MTU on TrueNAS and 9014 Windows and all is good now. I am getting 10G transfers
Do you run 10 gig at home? 1 gig? Or WiFi only?
I run my server, my computer, and my partner's computer over 10Gb currently. Mikrotik switch and sfp+ cards with fiber modules in each machine. It's so overkill, but it's great for my lack of patience in massive data transfers.
My workstation is in the same room as my rack so, 10G between 3 servers and my workstation (CRS305-1G-4S+), and 1G everywhere else.
I have been doing 1gig but recently have been transitioning to move things over 10 gig. Installed 10gig adapter on the pfsense machine and the ISP router already.
I have been looking for a switch that serves the purpose and this one looks promising. I want to do 10gig on the nas, proxmox server and the pfsense machine.
The house is wired with cat7a running on 10gig, a bit overkill. cat 6 would be the best option as cat7 cables are freaking stiff
I run 10gig to my file server and router (in the same rack) and to my office, but I do want to replace the cat6 run to my office because those rj45 transceivers get hot.
Hey my new house was wired with Cat5e and 10G worked just fine (just over 8 like yours), surprisingly.
ROWL in da house!
Just to demystify this topic a little bit (because it's less complex than people think):
(modern) Ethernet fundamentally just needs 8 wires to work, so any 8-lead cable can run any speed in theory. They are all wired the same electrically.
What determines if you can practically run a high speed though is the signal quality - which is mostly a function of the length of the cable, but also the quality and Em noise separation. The higher speed, the cleaner the signal needs to be - so either better cabling, or shorter distance.
In a typical home with relatively short wiring you can usually run much higher speeds than the cable is rated for, because the cables rating is usually designed around 100m or so.
Thus, if you have a 10 or 20m cable you can run it far "above spec" without issue, because the short length more than compensates for the worse cable quality.
If you run a higher speed than the signal quality can handle you will get packet loss. That "wall" hits pretty fast, so it tends to work either flawlessly or terribly (or not at all more likely).
I would always recommend checking packetloss under stress when running a cable out of spec. It tends to be be fairly obvious if it's fine or not.
TLDR: If you have old cables in your home, you should test them before upgrading for higher speed. Chances are you won't have to change them - or at worst, maybe only your longest cable run.
I need to lay new wires and will probably shell out the cat7. It’s gonna be an expensive mess digging concrete
Not sure if mentioned before but the Copper SFP+ modules run hot and I would not recommend sitting them next to each other due to the heat they put out.
On short to medium runs usually cat5e isn't an issue with throughput as much as it is with it being damaged over the years or getting interference from other systems. Many people have Cat5e running in a industrial or somewhat hostile environment and they will not have a good time with 10GBE.
Cat5e for the WIN!!! Excellent video Tim!
Im wondering what adapter are u using on PC side to get 10 gig ???
It's in the description!
Shouldn't see as much delay when you type now.
Can someone tell me how i can get gigabit speed internet
A lesson I recently learned is that SFP+ modules negotiate 2 speeds - between the switch and the module, and between the module and the PC in your case. The link speed shown in UniFi is only the former…it won’t show the link speed between the switch and the PC. You can only verify the links on either end of the module.
Then why did it auto-negotiate 1G on his machine that also reported 1G? I would think it should have shown auto-negotiated a 10G for the switch with his PC reported connected at 1G.
@@jonmayer A fluke? Wasn’t fully seated in the SFP+ port? I’ve fought the seating issue before.
Don't forget, Windows file copy is only a single thread process so the numbers won't be that fast. Linus Tech Tips ran into the same problem when upgrading their network.
NiTeHaWKnz... Just remember that depends on the SMB version you are using... SMB 3.0+ can be multi-threaded and even multi-adapter using SMB-MultiChannel. You can check this looking at powershell with get-smbconnection and get-smbmultichannelconnection. In my case I have a dedicated 3.1.1 server utilizing 4 40Gb nics and the storage to back it and I am able to read at about 12 GB/s or ~48Gb/s.
Just use robocopy
The copy is working just fine and can hit 10Gbps as he saw in the first few seconds. The problem is the drive speed. It was able to go full speed because it was essentially filling up server RAM as a write cache. Once that cache is full, then you are only getting raw write performance.
This is no longer true as of SMBv3 and the CIFS version that supports the multithreaded CIFS implementation. This is recent (last 5 years or so) but has been present on Windows Server and Client OS since Windows 8.1 was released.
He literally compied files at 1 GB/s, which works out to just under 10Gbps. 1Gbps is equal to about 125MB/s.
Its actually kind of funny to see your 'live' reaction to this. This just shows how enthusiastic you are!
Yeah that reaction was completely relatable.
Over 1G network sometime you have to "Hard code" the speed in both side. In a core network, we'll never use auto negotiate, we must hard code the speed at both side, it will more stable and will not suddent drop to other speed.
What do you mean by hard code?
@@perfect.stealth To set speed manually in settings.
That's not a thing and doesn't do what you think it does. Gigabit uses auto negotiation no matter what.
My house was built in 1997 before the cat 5e spec was even a thing, and was wired with decent enough quality cat 5 (no "e") that I actually can get 10G over the ~30ft from my living room to the garage.
Cool project. On your auto-negotiation issues, I have heard that SFP+ to RJ45 modules can have issues negotiating 10G on Ubiquiti and is just better to set the desired speed manually.
The X540 intel 10gbit adapters are sometimes finicky. I use them for all of our production equipment and they work fairly well. Check your switch's stats on that port for CRC errors. That would tell you if it's clean.
I've had the same doubts. And found basically the same answers kk I'm just so glad that you've made this video. Amazing! Congrats for your content.
That's awesome and gives me hope. I have a cat5e cable going up one side of my house, across the roof and down the other side. It is a 2 story house, so I think I may be coming close to that 55m, but at a guess, I think it's about 45m. This connects my 2 parts of my homelab, where I have rack servers sitting on a cupboard, and the other end to my office. I have wanted 10Gb, but always thought the cable wouldn't work so never tried, and don't really want to run another cable, though I have a whole spool of cat6 that I was gifted.
Off to eBay to see if I can get some cheap 10Gb switches that support VLANS.
The amount of money I’ve spent at microcenter over the years is crazy
What you definitely should try is if you got any retransmission. With crosstalk and all that you could have a lot of broken packets
this
where do i look for those? in the network interface stats?
@@AlexanderBukh ethtool will give you anything you need
@@LampJustin thanks!
The SFP+ to RG45 converters are notoriously quirky and its no surprise that auto-negotiation doesn’t work reliably. Just set things to 10Gbe (like you did) and all should be well.
You might alway want to play around with setting jumbo frames (9k MTU). It can make a huge difference in transfer speeds at 10Gbe, especially to/from windows which does single-threaded IO for most file transfers.
for 2.5gbe what mtu to set? o-O; is default good enuff?
Yes it will... I test these things. It can't be recommended because of distance and interference issues, but yes you can. Hell, someone got 1 gig over barbed wire.
Makes me ender what the CAT6A in my walls could handle. 25Gbps? Lol
Cool. I know you said the cable is twisted all over the place, from attic to basement, but do you have a rough idea how long the run is that worked at 10G?
I used a cat5e for 10g that was 120' give or take a few feet. I used it for years. I needed a second connection is the same location so I ran a cat6a and used that for the 10g. I didn't notice any performance or speed difference between the cat5e or the cat6a, if it were serval hundred feet maybe. At 10g speed the real bottleneck is the machines you're transferring files between. CPU is a factor but the storage drives that files are moved from/to. As Tim did I assume the source drive was an M.2 sending to HDD you get fast transfer till the drive cache fills then you get drive speed. It's not just limited to the destination drive. If you're copying from an SSD to another machine with an M.2 the limit will be the read speed of the SSD for the transfer speed
It's roughly 120 ft, but I think I can check cable length on my UDM!
Generally Cat5e while not specced for 10G will handle it up to about 40m to 50m. Shorter is better.
You might not have IPMI built in, but you should put a Pi-KVM or Tiny Pilot in front of your PC-Server conversion so you get those capabilities. :)
Does it matter if you are using Cat5e jacks or do the jacks need to be Cat6a in the wall?
That is awesome. I love to bust myths...
I'm currently running 1 gig through telephone wire which happens to have 8 wires... Everyone even said its not possible because its litterly not shielded at all..
Paket loss is a bit higher, I would say wlan standards. But speed and everything is awesome.
Love to see you manged 10gig with cat5... Sometimes it makes me think cable industry is a bit... Sketchy and never really tests their new standards...
Cat 5e isn't shielded (although you can get it that way), it uses twisted pairs. If your 8 conductor phone cable used twisted pairs, then you'd probably be fine as long as you wired the pairs up correctly.
What sort of "telephone" cable? Phone cable is 3 pair CAT3, which is rated for 10 Mb Ethernet for 100M. However, CAT3 is getting scarce these days, so people often use CAT5. Shielding has little to do with it, unless you're in a noisy environment.
Cat 5e is a beast.... Thanks for doing the test and confirming what I already knew as a network engineer
Just moved into a brand new house. I made sure that they ran Cat6 to ensure a degree of expandability in the future. So glad I had that option.
my whole house is cat5e pure copper. I hit 10G no problems. I get about 777MB/Sec transferring to my Storage spaces 3 stripe 32KB, 64KB Allocation size in parity setup. Pure HDD Pool.
Nice!
I've run 10Gbe over Cat5e in my home. It runs without a hitch.
I jumped from an HP ProCurve 24-port directly to the 48-PoE-Pro, and couldn't be happier. I also added a fan inside to keep things quite cool. It's a powerful device, and can be chained to multiple copies of itself.
micro center... looks like what Frys used to be... I miss frys :(
No micro center in the phoenix area :( I have to drive 6 hours to LA to go to Micro Center.
worth it!
I can see the future video....Upgrading my storage to keep up with my 10G network. lol
Nailed it
When I forget to some MAC address and a device drops off I dump my arp table to a text file. Maps ip to MAC and makes finding it easier. Has saved time at work and home.
Why didn’t i think of that. Definitely using that one, thanks man!
Very exciting stuff. I have about 130ft run I need to do. All I have laying around is CAT6 and came across the same problem you did. Officially, MikroTik only supports SFP+ to RJ45 for 30 meter runs.
The rest of my network is all Unifi, but unfortunately hard to get my hands on nearly ANYTHING 10 gig for a decent price. I even had to resort to ebay because Mikrotik devices are selling out fast.
It's good to know that I'll be able to do something temporary until I can terminate my own fiber. By chance, do you know if LAG works with SFP+ 10 Gig? I can try to find a dual port 10 Gig PCIe card and just run 2 drops of cat 6 while I'm at it. That should get me up to 10Gig or higher speeds.
Iperf was updated to the iperf3. Recommend you to try 👍. Great video, by the way!
I just upgraded from a 50mbt fixed wireless solution to a 2gbt fiber service (Thank god after waiting 20 years for REAL internet here!!) so I'm looking to upgrade my infrastructure here in the house. Running Cat5e as well so may just use what's already here. I run a lot of stuff over wireless but all of my core services are on hard lines.
I was pleasantly surprised when Cat5 (non-E) in my walls did 2.5gbe. Unfortunately my little itx gaming rig doesn't have a 10gbe NIC like my server does.
Officially cat5e (with e) is fully supported for 2.5gbe. That was the whole point of 2.5 gbe. Otherwise the next step was directly 5 gbe.
ive run cat6a non-shielded cable and keystones. i have no 10gb equipment (yet), however i do have some long POE+ runs. wanted a thicker gauge wire to reduce heat generation, and future 10gb expansion. pulling cable sucks sometimes.
Yes you can, it really depends on the quality of the cable and distance along with how its run (EMF Exposure)
that speed drop while copying could be because of how windows manages copying files
Yea Windows only use 1 thread. That being said it could also be the hdd which is out of caching. The moment the cache is empty, you rely on the actual disk speeds (read and write)
I also bought a Cat 5e to use with my four QSFPTEK SFPs, it's cheaper than what you use in your video, as you don't have much budget, but my computer-to-computer transfer speed is about 800 Mbits per second
Just my opinion, but if they ever have better /more conductive connectors than gold plated brass it'll boost more length meters. Silver plated is more conductive than standard the gold plated.
I don't know what you did with the cables to begin with. But if you put them in proper cable channels, then it would be easy to tape a new cable to the old one and pull it all the way back with the help of the old cable. No need to crawl in the attic...
It could still work without a channel, but could snagg on something and if you stapled it, it obviously won't work at all.
Unless they were stapled in the rafters. :(
I have upgraded some Weeks Ago (USW-Pro-24), but just my Server (DAC, its in the Rack with the switch) and my Desktop (Upstairs, RJ45). I wired the house with CAT7 cable when we bought it 8 years ago. I ain't got working full 10 Gbit at first try at my Desktop. I thought I messed up some shields at the Patch Panel, but it was a faulty (bought) CAT6A Cable wich connected the Desktop with the Patchpanel. Greets from Germany
When doing an iperf3 test, always test with a Linux machine at both ends. Gives you near wire speed, whereas Windows tends to limit you to 7 and change gbps. Apparently, WSL gives you slightly more, but it is still limited.
My workshop to my house is 10GbE using exterior grade MM Fiber, but I need to extend it to other parts of the house. I will probably connect my wife's office with 2.5GbE because that's better than WiFi at least.
I have a 1 Gbps network, and mostly Cat 5E wiring, my transfer speed is around 800 MBits per second from computer to computer. I do Lan speed Test.
10Gbe can be finnicky or resiliant... it purely depends on the adapter and its tolerance... the mac mini m1 10gbe interface is not resiliant at all and will try to hold a 10gbe until it gets noise then it just drops down to 1gbe and never recovers... whereas the newer mac studio 10gbe interface will recover and yield an effective higher rate... over the cat 5e that i have thats about a 50 ft run between 2 walls, mac studio gets sustained 6.5g up and 9g down, but the mac mini will only get 6 up / down until it hits noise and it drops to 1gb for ever until you reset the adapter or pull the network cable and reconnect... so a lot of the cat 5e performance has to do with how resiliant the nic and software is.
Thanks for your video! I have a 6cat in my flat, so maybe I will get even more than 8Gpbs. I use a UDM Pro and it has only one SPF+ LAN port, so I can just try to connect one of my PCs to it, but to connect a second one I have two troubles, first off all I need a 10Gbps switch, but I don't want to buy it right now, and the second problem is that my client PC workstation has no free 16/8 PCIe slots for a 10Gbps NIC, because one of them is used by GPU and second one by RIAD controller, haven't found yet a solution for a 10Gbps in x4 PCIe lane. But maybe in future I will change my motherboard to a newest, with a built in 10Gbps NIC, yeah, they are puting such speedy adapters to a "home" workstations. Best Regards!
Thin cables aren't really compliant over distance so for best performance don't use them as patch cables for in-wall runs.
Most offices don't have that luxury as they are wired with cat5e
i just switched to 5gb fiber for my home. What switch would you recommend. It came with the tp-link AXE300 6e 16000 router.
If you get the correct SFP+ transceiver you would be able to have 802.3-bz with 2.5/5/10 Gbps speeds. On you Linux can you use `ethtool` to verify the speed.
I plan on running 10gig between my "high performance" NAS and my main PC. This NAS has all movies, games and hot storage for photo and video editing for me to offload most of my drives and hard drives away and use rundand drives.
A lower performance NAS can store all "archived" stuff but yeah. For the rest, I'm probably going with 2.5gig or 1gig. Our fibre connection is "just" 1gig. Most of my devices don't support more than that and I think, for the current price and my situation, 10gig on scale is currently useless. To become useful, the price has to drop quite a bit more. Maybe, I use 2.5gig. Cable's not been any issues here. I think, my "weakest" cables are CAT6? So definitely capable of 10gig.
And if I'm going to buy a home or built one, I'm definitely going to squeeze in the best, I can afford to future proof my home. Probably CAT8, as it's not too expensive anymore.
But first, I need to wire up my current flat correctly and set up my cables properly. Currently, everything's a mess and I don't even have a good, central storage solution for the devices nor proper cable management... :D
BUUUUUUUUUUUUUUT it works. I don't really know how and why but it works. And I'm not going to question it xD
I'm literally in the process of buying a condo and I discovered during inspection that all the phone jacks were wired with Cat5e, so I was already researching 10G over Cat5e when I saw this video. Excellent timing! I'm going to give it a shot after I move in.
I bought my condo 29 years ago and it was wired with CAT3 and daisy chained jack to jack, so not the greatest for Ethernet. However, when I got my cable modem, in the late 90s, my ISP actually ran cables in for me. I wanted the modem in my "office", which is at the opposite end of my unit from where the cable comes in. My ISP sent a 2 man crew who spent 3 hours fishing the cable up inside the wall between my living and bedrooms, along side an air duct, over my closet and bathroom ceilings and into my laundry room, where it crosses my ceiling, then down behind the water heater and through the wall into my office closet. While they did that, I had them pull in a couple of runs of CAT5 (5e wasn't available then). They even patched the drywall where they cut it. In addition, they put red "Data" tags on the coax.
@@James_Knott good guys
i know this is kind of old, but cat 5e says it only supports 10Gb for really short distances (100ft or less) ... just saying this to make others that may watch this later that don't know this be aware since you mentioned you have cat5e ran all over in your attic and stuff and don't want people to think that if they run cat5e they will always get 10Gb especially if they need to run more than 100ft (33m). Anyone that is running a new network at home really should just make the jump to Cat6 since that is good for up to 55m... Cat6a is good for 100m according to the specs, but the cost just may not be worth it. The other option would be SPF+ using MMF OM3/OM4 if you really need some long runs but those SPF+ modules add $$.
really for most situations, i would think that 2.5Gb is more than most would need for just normal type stuff (cat5e or Cat6 is more than sufficient), but if you transfer large files a lot and would really honestly benefit from the 10Gb performance then maybe going cat6 or Cat6a would be worth it when doing new runs. I just cannot get over the pricing of 10Gb switches. The Unifi 24XG can do it but it also doesn't have PoE. Their Enterprise 24 can only do 2.5 Gb on most ports. The Aggregation Switch from them has 10Gb for its ports but are all SPF+. For me the cost of going full 10Gb is just too much than going 1Gb with just some fast uplinks to different areas... then again, i also don't transfer large files on the regular so it fits my use case.
To have a continuous test of iperf run the following: iperf3 -c -P 8 -R -t 120
Not sure about those RJ45 SFP but with DAC, you need a SFP+ DAC and SFP+ connector to get the full speed. Using SFP cable on a SFP+ connector wont give you 10GB/s only 1GB. Learned that the hard way..
10 gig - does anything in the home use 10 gig. Computer to computer limited to the speed of the hard drive. OR SSD that 550MBs at the high end. Unless you RAID them but most home users do not raid hard drive or SSDs. Now anyone that renders videos would have a need for it. but yes the CAT5E cable should pass 10gig and most homes would have a low RF interference with the cable. Unless they have High power power lines. I have run into that before. We could run LED inside the house with just a coil of wire in the living room. but that was a rare find.
I've watched all your videos, you're an awesome dude.
When that 10Gb connection kicked in, I think that's the first off-script, out-of-character I've ever seen you. Most the time, it seems more like you're reading from a script; this was more akin to the first time you ever had an orgasm and didn't know what was going on.
Absolutely loved it brother Timothy, but thanks for not showing us your pants afterward.
I have a 3ft cat5(not E) cable that will auto detect to 10gbps. I use a 4ft cat 7 cable that I feel works better for the 10gb run though. I have not done tests to see if there is a physical limitation of the cat5 cable compared to new cables.
Tim, thanks so much for doing this test. I have a Ubiquiti US-16-XG UniFi 10G 16 port switch (12x SFP+ & 4x RJ45) on backorder and for RJ45, I have a bunch of CAT5e cables and nothing better, so I'm glad to see those will work for the time being. Because of cost, I was thinking of getting some used Mellanox CX311A 10Gig SFP+ cards + transceivers and fiber cables for my main PC, the Cisco server I have and two NAS's. Everything is in my office so all short runs.
10G BASET - most of the time the auto-negotiation does not work really well on "consumer" switch hardware
also grounding on the CAT cables plays into the circumstances why it has troubles syncing to 10G properly
GBIC can't be good for this ...probably best to go with a native 10GbaseT type port. Also, should be checking packet error stats instead of throughput.
For short runs (like in a typical home) and low EM noise environments, Cat 5E is often enough. But, remember its cable distance, not human walking distance. Also following paths for power lines (ie: HVAC, kitchen, bathroom) can cause issues. Living near a TV or radio transmitter can also cause problems.
Indeed it's all about quality/ noise on the line. Hence cat6 is better isolated.
tl;dr I already know it works.. it is one of those things that are out of spec but do work in shorter distances. now should you run cat5e on a new network ? Like my fokin isp did when i wasnt looking? No. use dac cables for short distance, fiber for everything else ..ethernet when there is no other way.. will cheap-bastards-inc isp cabling do 10gig if I try? Yeah, it probably will.
I currently have a Ubiquiti 16 port Poe switch and I just purchased a Ubiquiti 24 Port Pro Poe switch. Do I need to do anything prior to unplugging the 16 port and installing the 24 port? I assume the 24 port switch will just pop up to adopt and I just go through adopting and it will work?
But will it be _stable_ and _reliable_ . Iperf and file copy might show you good numbers, but will you experience unexplained file copy stalls, or weird disconnections mid transfer etc...those "wth just happened" issues....how has it been since this video was uploaded?
So the limit is not the cat5e cable but the other hardware in your PCs like the slow spinning drives, which Synology uses in their nas so max speeds will be 500-600mbs no matter what. 10G is literally a pipe dream, pun intended.
I have the Aruba S2500-48P. 48 ports of gigabit POE and 4 SFP+ ports. I used Finisar 10gb SFP+ multimode modules with 10M of OM3 LC to LC fiber cable. Both worked great connecting the Aruba switch to my Mikrotik 10gb SPF+ switch.
Great vid!! Someday I'll get >1 gig setup in this house!!😁👍
Interesting. I use noctua fans in my home lab to keep it quiet so I can have the whole rack next to my monitors and desk. (No basement for me to stick it in anyway) for me a new run would be as easy as unplug and put in new cables because the only thing coming off the home lab is display cables and a kvm for my keyboard/mouse.. its kinda silly having a whole 48U rack next to you while gaming but you get used to it.
@Tim, to be sure you have a stable 10Gig. Best to check your Switchports on the switch. Look if they do not flap and you do not see any errors on those ports.
Where the files transfered successfully? Check the hashes :) TeraCopy does it automatically :)
9:47 Uhg. DHCP on UniFi ... I have a machine on two separate VLANS, one for storage access, and one for everything else on the network. Half the time name resolution gives me the IP for the storage network and the other half of the time, it gives me the IP I actually want back.
The main difference between Cat 5e and Cat 6 cabling is signal attenuation.
To get a specific bandwidth we need a minimum amount of signal to noise ratio (SNR) at the receiver, and the sender only has X amount of power it can deliver down the line.
So more attenuation means a shorter distance is needed before the signal strength is insufficient to achieve the needed SNR. However, other factors can also effect SNR, so in more electrically noisy environments Cat 5e can be insufficient at lower distances.
In general for home and even office use, Cat 5e can carry 10 Gb/s Ethernet for 20-30 meters without issue in most situations. However, not always.
Cat 6 has thicker wires that gives the signal a bit more surface area to work with, effectively lowering attenuation. Also makes DC power distribution via PoE easier.
Cat 6 is often also having a spacer that spaces out the 4 pairs from each other, reducing crosstalk and improving SNR a bit more. Some cables have a shield as well to protect the cable from external electromagnetic interference.
Then there is also Cat 7 cable on the market, but the networking industry don't really use it yet. But it tends to have individually shielded twisted pairs, as well as a shield around all four pairs. And on top of that the different pairs use different amounts of turns/twists per unit of length, this is to reduce crosstalk even further.
But in short, the things of importance is the signal to noise ratio at the receiver. Even just hand wiring some loose copper strands with minimal twisting can run 10 Gb/s Ethernet as well, though not particularly far.
You can actually get some pretty long SFP+ cables. The advantage is very very low latency compared with CAT7.
@@wayland7150 The Cat rating of the cable doesn't really affect latency.
But yes, Direct Attached Copper is lower latency than a pair of SFP to Ethernet converters.
Mainly since Direct Attached Copper is literally as the name implies, the Tx differential pair going to the SFT port just gets routed straight over to the Rx pair on the other SFP port.
Ie, no logic, nor any protocol processing.
DAC cables though have signal buffers to ensure that the signal makes it over, but this adds almost no appreciable latency.
Regular optical SFP modules work in the same fashion, just instead the signal buffering drives the light source, or reads the optical sensor on the other side.
@@wayland7150 The average person wouldn't notice the difference in latency. You're talking hundreds of microseconds. and there is no reason to bother with Cat7 for 10 Gbps, it's not even recognized as proper cabling standard either. Beyond Cat 6 it goes up to Cat8. Again there is no purpose for it for 10 Gbps.
@@todayonthebench There is a huge different in latency between CAT6 and DAC. Forget The Average Person because they can't tell the difference between 100meg and 1gbit so have no use for 10gbit. The exceptional people who do care would be very keen on low latency because in some applications that's the crucial factor like gaming.
@@wayland7150 Any latency differences in cables on the local network gets dwarfed by the latency of the internet at large. So for Gaming the local network cable delay isn't really going to have an effect on latency.
The latency of cables only starts to matter when one deals with local network storage for database applications, or for clustered computing workloads. Not gaming.
Hi tray MeshCommander and Intel AT if You have Intel CPU on that serverbtw connect internal on mainboart nic to myour network/servers managment network and sewt ipv4 as static on that nic

i would say on cat5e depends on quality of the cable, but i wouldnt use cat5e for 10gb, i know because cat5e on 1gb wams up when transferring a lot of data but nothing dangerous, but i dont know about 10gb how high, also cat5E has no shielding to protect it from outside influence like other cables(electric or network). you dont need to do holes, just pull the old cables while the new cable its attached to the other end. :) fiber doesnt heat up or is being influenced by outside sources. would go with cat 7 or 8 for an upgrade, prices are quite low for them so for future prof would recommend them, if you have less than 40m distance between connections you can go with cat 8 for future 40gb connections but isnt cheap
Would like to find a video (honestly havnt searched yet but will look) on a video for that iperf and windows 7 and unraid. I have 10g in both (and another in a win10pro machine) but not seeing decent speeds, could be the spinning rust not sure. But didn't notice a difference between the 10g and standard 1g....
always worth reminding people that most devices won't fall back to 2.5gb but to 1gb when failing 10gb
When’s the next video in the upgrade series coming out?
soon!
I have a UniFi enterprise switch, so before I go wild with 10 gig Ill make it works with some 2.5 gig, but yeah I learned on this video
Nice that you got the cat5e cable to work. How long are your runs of cat5e in your tests? You said it was up in your attic but what are we talking about? 20ft? 50ft? More? Thanks.
A few things to note.
SFP+ to RJ45 transceivers are known to have tighter limitations on 10gb distance, and if not for the fact this is a switch you’re running on, would have been better to seek this functionality natively as there’s a bit of a heat problem. Good to see this worked out for you though.
Cat5e is not rated for 10G, so you’re playing the cable lottery. You should get cat6A when you have the opportunity. Most devices will autonegotiate at 1G when they detect the signal quality of Cat5e. Typically, if you truly won the lottery, it will autonegotiate at 10G thinking it’s cat6 or 6a.
Either Auto Neg or hard set on both sides. If you have a mismatch of hard setting an interface then problems will occur.
Excellent video Tim, BUT you failed to mention 1 CRUCIAL piece of information, how long is your CAT5e run? This is a question I have researched several times, and like you I saw varied answers. We desperately need to know HOW LONG THE CAT5e RUN IS?
I think it's about 120 ft, there's a command I can run on my UDM that tells me. Will report back!
Hi Tim. Have you enabled Jumbo Frames ?
Hi! I have not yet. I am not sure what the benefits are.
my understanding renegotiation in switches, if you have 4 spf+ ports they are shared ports with the last 4 ports of the standard side of the switch, you use the either/or principle and not both...
Why don't you use much cheaper SFP+ NIC and DAC cable for a server located close to the switch?
PS Don't forget to set MTU to something more than standard 1500 bytes, most modern NICs support 9000 and even more, this can increase your throughput and decrease CPU usage a lot.
Good call! I will use SFP+ cards for servers in rack but wanted dedicated nics for those using ethernet
14:10 not 500 MB/s.....5000 MB/s.....!!!!!
Yo you need to set up a pikvm. Edit: Never mind, I just saw you did a video about scaling the pikvm.
sudo netplan try
not so important when you're on the machine console, but doing changes over the network? Life saver.
Oh dang that's awesome! Gives me hope for all of the cat 5e I've got running all over the house....now time to shell out some dough for 10G equipment!
You used old iperf (no idea why Debian still have it). Apt install iperf3 for the current one.
Didn’t know iperf existed, really useful. Thanks for that
Hi Tim. FYI. I had issues with my 10G connection to TrueNAS. I enabled Jumbo frames and Flow Control on my Unifi switch, 9000 MTU on TrueNAS and 9014 Windows and all is good now. I am getting 10G transfers
Thank you! I ill give this a try!
Tim is the window into my future! I'm looking at running a little 10 gig to and from a couple of machines, but have some room to grow in the future.
This is a great example of troubleshooting. 👏
Good to know, really. Saving me few bucks. Thanks
