Nice demos! My two cents on RAIDZ1, I did it with 4x 3 TB consumer HDDs for ~3 years after which 1 drive failed, but it didn't fail cleanly, it started silently with increasing bad sectors and then ZFS read errors, the drive never actually failed. For a little under a month I had a degraded pool with no parity while I was trying to figure out if the drive was salvageable, 100% do not recommend that stressful experience. I only did it because I was a university student with a very limited budget. I now run 8x 8TB in RAIDZ2 with a much better managed 6 monthly off site backup. And would you know it one of the drives failed within the first year although it at least had the decency to fail completely and suddenly this time. But it still took over a month to send the drive back to the USA for RMA and receive a replacement, but I was resting easy knowing I could still lose another drive and not suffer any losses. For those building their array and that have some flexibility to you budget, I would recommend you prioritize RAIDZ2 (or better), even if it's instead of a L2ARC or SLOG device (for most applications), future you will be very happy you did. Only thing I wish I spent more time considering with my build is power consumption and noise, kinda wish I went with the two separate pools of 5400 rpm drives and another of SSDs rather than my current 8x 7200 rpm drives (8 W per drive at idle!).

Just awesome, look forward to future videos on astro photography

great video. look forward to seeing about the support vdevs

First, But also thank you for your uploads, I would love to see more things like this, tutorial like videos for those stepping into this world of Homelab :)

I wonder...how do you account for water leaks in the basement?

cool stuff you're smart.

Way overkill for a home

You have more server than my company have 😂

I have a 5900x I can run like 12 vms on... I drool thinking of this much processing power and backup

make a video showing the old pcs, please.

I hope & pray this man's channel reaches as many of our youth as possible. Younger generation is severely lacking in role models. I'm in my mid 30s now & realized that having a mentor very early on in life is crucial to one's success later on in life.

I used to use loads of SM chassis with the JBOD boards like you demonstrated. They worked OK but the backplanes became extrememly touchy with age and I got the irrits with swapping supposed failed drives. Went to EMC chassis and not a single drive since, 60x HDD's and HW RAID, simple and fast. LOL, I started out with Norco's. They still good for small users and a media server.

What you use all this for ? :O

Brother in Christ, how large must your house be to store this entire data center?? I unironically would love to see a house tour, because this is just insane!

Love your video Jeff!

Lol my "homelab"

He said “pretty simple stuff here” hahaha yea right

It's all about playing for yourself on the computer 😁

Beautiful 😍😍

Now I must know how many kWh you are averaging a day month in electricity bill

fucking awesome.. are you kidding me??? holy moly

LMFAO that's a datacenter in your basement.

beautiful

why ????

homelab: just exists lightning strike: ⚡⚡⚡

This is my 20 year plan

You are out of breath for working down the stairs. Maybe you should work on that dork

It sounds to me like you were serious cosplaying as a server admin and "just" needed to build a new house to do it! 😇🤣

Never ever stop making content! This is some of the best content I've seen in the homelab space I've seen in years. I've recently been planning a big upgrade and this is exactly the content I've been looking for. Current setup is a 24 bay SM chassis running unraid. I've just recently upgraded everything in the house to 10gb available. The old server is running an older SM JBOD motherboard so I wanted to update everything. Ended up going with a Threadripper 3790X and 128GB DDR4 for the "application layer". The plan is to start the new server and run in parallel and add the first new hard drives to that machine so I can transfer all my old data over and destroy the data on my old unraid box and then I can transfer the new hardware over the 24 bay SM and have a nice new setup there. The part I was researching was changing to a distributed model for data so this video has been a gold mine for me. With how cheap you can get older SAS3 SM 45 bay JBOD chassis this seems like the best route. I'll be very interested in the topology video because I was debating between mirrored pairs or going with a Z2 or Z3 setup. I used FreeNAS back in the day so familiar with zfs but its been quite a few years since I've used it. It seems like running a ceph setup or something to be able to add nodes (or drives) horizontally makes sense for scale. I'm planning around a 1-2PB physical capacity at the moment (planning much much into the future as this is a long term plan...current setup is sitting around ~200TB).

Thanks very much for sharing. I saw another comment asking if you'd do a tour of the fire system - I second that. I also appreciate the bit about 240v - I am about to run 240 to my lab and it took me far too long to understand what exactly single phase 240 is, and that 208 isn't really an option for residential. Looking forward to whatever you come up with next!

Oh yes! If a server gets way too hot just put some LEDs on it and it will be way cooler! 😇🤪

Not many people could make SAS controller's interesting. You remind me of some of my DEC instructors who could provide a large amount of information in a short amount of time, and made one hungry for more. I'm looking forward to the next segment.

May I ask what you use all of this for?

alot of linux isos

100 tb is small... ok bill gates

"My minecraft server"

Amazing! Well done. I have a house build in 1897 and have fiber runs from the demarc to the server room and then up to the office. So much harder to do as a retrofit, love that you could prewire and sure you will make use off the majority of that cable someday.

Great video in time for my homelab adventure, thanks Jeff.

You sir just got yourself a new subscriber!

Thank you for clarifying all of that! I bought a SAS2 HBA thinking it would be enough bandwidth. Now i know i need a SAS3 HBA. Conveniently the case manufacturer offers a 12G replacement backplane with an internal expander to upgrade. The SAS2 HBA will then be used for a small SATA SSD array.

I've seen your homelab on reddit a few weeks ago!

200TB for a small homelab??? you live in a complete different world 😂

Can you please continue project Roscoe 🙏. It was very informative. And you mentioned FPGA in your videos, so please make video on MOSFETs sir how it works to understand the electronics better

What software you can recommend for backing up windows and android? On Windows: backup whole disks On Android: whole backup and only photo+video

Awesome man. I was watching these videos out of curiosity of the home lab, but definitely didn't expect astrophotography among what you're into. My build is extremely similar to yours -- William Optics RedCat 61 with a 20mm finder and AM3 mount. Basically everything else you have is identical to mine. Ironically too, my desktop background is the Skynet logo on your t-shirt ... lol. Do more of this!

OMG, where have been this channel during my entire life??? Awesome content, awesome hardware, awesome communicator and AWESOME skills! I love it!

Fantastic video. Ive been looking into building a NAS but was struggling to decide between the three configurations you outlined. This really helped clarify some of the considerations between them. Looking forward to the next in the series

So I am wondering if you can explain how would you do ssd drives and hard drives in jbods and how you would have them connected and what would be the for the best performance I am wondering because I am looking to add jbods to my home lab
