Just landed on this page, enjoyed the video, although CSE847 (jbod 45) would be a better choice as this has 7 fans and 2x 1400w PSU. Anyway, your heating issue on the 16 drives is due to your placement, your blocking the airflow, turn the disks by 90 degrees and you will have a better airflow.

Thank you

Did you break even?

I am still using the 1U Supermicro pfSense build you first made a video about. It works great.

Great video I also try to avoid copper when it comes to 10g networking due to heat I have a few RJ45 based 10g nics I don't even use them because of the temps. I'm currently moving all of my services from ESXI over to Proxmox so I'm definitely in the market for a 10g switch.

Wireguard, it's 2025.. 😀

Where is affiliated links?

another great video. i use to use openvpn on pfsense, but now i use tailscale in pfsense. bypass all the this setup. much easier setup.

hey bro，use pfsense Means your data will trans to your home server first?

Next episode: wireguard?

Don't ignore RouterOS L3HW features! This device CAN act as L3 switch too! It can't offload NAT, but it still CAN offload good piece of routing by switch chip.

sir how to block netshare app in mikrotik router 😇

sir how to block netshare app in mikrotik router 😇

sir, can you please teach me the steps to migrate DHCP ISC TO DHCP KEA. i'm scared 🥺😥🥲

Still you continue farming this shit project?

Can you boot from these NVMe SSDs?

life saver sir! thank you!!!! Please make the command line bigger in future videos! Love this video!!!!

It solved my life, I was already giving up on using nvme on my supermicro motherboard, thank you very much

Splitting up a 16 zone into 2x 8 zones i was thinking.. recently.. after visiting the bios switched a setting and the network was gone another learner curve.. but where to find the splitters ?

I purchased a CRS309 for my server backbone network. It’s been great! I’ve got a couple of VLANs on it and yeh it’s different to setup. Nice video

This guy reminds me of one of the "ThePirateBay" team members.

Your videos are really nice and I like watching them but can you please put Turkish subtitles on your videos?

I've been investigating StorJ for a little bit now and still am not yet ready to pull the trigger. I have 1000/40mbps and am not sure I really wanna donate some of my bandwidth at the moment. I guess maybe I could put a QoS or something on it? And I was thinking of making a little PiNAS for power sipping which seems like it might be a good use for this?

wow and zamzam water

When first getting connected to the switch, there is no need to faff around with ip addresses when using winbox. It can connect on layer 2 (mac address) and you can then set the IPs from there. Like others said, using DACs for anything within the rack is both cheaper and more energy efficient than fiber. It essentially omits shifting the signal to a real "transport" layer (like light for fiber or true Ethernet levels for copper). DAC cables cost around 15-20 bucks per connection, where a fiber would cost probably 10 plus 2x 15 or so for the transceivers.

I run two of these; one acts as the spine for my network - the RB5009 acting as the edge router feeds into the 309, and then the 309 feeds to all upstream switches. I also have a second one that acts as a storage backbone (separated from regular network) with Jumbo frames enabled, connecting NAS to ESXi. Note - I don't use any of the router functions; just bridge level switching. Router-level stuff is all done by the RB5009. Great router/switch.

I migrated my homelab to MikroTik in 2024 and their equipment is awesome. RB5009UPr for routing and PoE, the CRS309 in this video for 10Gb switching, and a CSS326 for all of my 100Mb/1Gb devices. For those who need something smaller and cheaper look at the CRS305-1G-4S+IN... $130 for four 10Gb ports and a 1Gb port. Learning the software can be intimidating, but there are hundreds of videos providing detailed walk throughs. Also, lets not forget about DAC's. They work great for intra bay 10Gb trunks and don't heat up.

You're doing a fantastic job! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?

I’ve had a Mikrotik CRS309-1G-8S+IN Switch for a few years now. It’s a very nice bit of kit especially for the money so I highly recommend it. I use a combination of DAC cables and SFP+ copper transceivers. I’d probably buy the same switch again if I needed another. However, the Ubiquiti UniFi Aggregation switch is approximately the same price with the same number of SFP+ port and the addition of an LED screen on the front. No out of band management port though. A bit of a tough choice if you haven’t used either product.

why on earth multimode?

Please note, that newer Mikrotik devices come with a random password to comply with California rules. The password will come on a sticker on the instructions leaflet and on the base of the device.

The algorithm brought me here, and the subscription means I'll be back. Great job, keep up the good work, and hope to see that VLAN video!

Dont use multimode unless its legacy, singlemode is what most of us in the industry sre using. Price is nearly the same, and you dont have to stock multiple different spares for everything.

SwitchOS not supporting changing management vlan is criminal. @normis, please fix this. Vlan 1 management is so 1999.

Good video ! about temeperature sfp+10Gbit cooper it's true,it's make module very hot, and increase consomation of energy. At other side you need use RouterOS instead Swos, with routeros you can win switch features like L3 hardware offload and QoS HW and use Switch like OSPF node and it not increase CPU consomation. You can use also option 82 DHCP and many other features wichs not possible with Swos. In all scenarios RouterOS win.

The Supermicro version of the x520 tend to run cooler, I have a bunch of them in HP T740's in my mini lab.

Just took one of these out of my lab, replaced with CRS326-24s+2q+rm, building out a big lab and mini lab and ran out of ports on the 309. Running routerOS mostly, but once in a while I flip over to swOS. Never saw any real world speeds differences with what I was doing. The only issues I've had was with some modules, sonetimes you need to configure the port speed manually to get the prot up, especially with 1.25gbps modules but akso with my only QSFP+ breakout cable.

No! you do not need to change your networ settings to access mikrotik devices. dont use the web interface but instead use winbox to manage them.

Just stumbled on your channel, so thought I'd say hi. The "Histogram" tab, I would assume (seeing and using other vendors) tracks the number of frames switched of various sizes. For the most part, people don't care about these numbers, but as you know, small packet sizes add a very high % overhead to a frame, versus say 1500. Someone may ask, what does your payload mix (imix - internet mix) look like, and you'd go here and say it's like "this", but this is very, very nitpicky.

I Think I have had my Mikrotik 10Gb Switch for 3 Years maybe 4 & Still Going Strong ! They are Pretty Hard to Beat For The Price IMHO ! O I Also have Always Run Mine in Switch OS Mode !

Yes please, need that video about VLAN's, because MikroTik does it in its very unique way

another CRS309 review ignoring all L3 HW offload features, something unfortunate

Good price. I've been happy with my CRS305.

Love the networking as well as the solar videos. Thanks.

Yes, a vlan video would be great as well as igmp snooping. Especially if you have multiple switches on a vlan with multicast traffic

Awesome video sir !!

My home is wired with CAT 8, which uses shielded RJ-45s and keystones. I use the Mikrotik CRS312-4C+8XG-RM and have done the Noctua fan mod so that it is much quieter. My computers came with onboard 10Gbe built-in, so this was the way to go for now. In hindsight, I wish I had run fiber, but I got a 1,000-foot spool of CAT 8 for cheap, so I went with it. The shielded RJ-45s and keystones were expensive but reusable, so I wasn't worried about that. The switch wasn't too bad price-wise, either. Had I run fiber, I would have also needed fiber-to-ethernet converters at each of my access points. There are pros and cons to either side... I enjoyed the video, and you gave me ideas for the future!

When is the giveaway? 😉 Thanks for the video and review, as well as the details on why you didn't go copper. I'm still partial to DAC for short enough runs, but for anything longer than that, fiber is nice. My backbone in the homelab is CAT6 10G, but mostly because I got the UniFi 16 port XG switches that have the 4x 10G RJ45 ports built in.

Don't forget about DAC (Direct Attach Cables). I prefer to use those in my rack as they are the cheapest, lowest power, and lowest temperature option. But can only use them to around a maximum 7 meters in length. I have the same switch but use RouterOS as I use it for my other Mikrotik switches.

Thumbs up 👍 thanks for sharing. Merry Christmas 🎄🎁 and happy New Year 🎊🎆
