I want to build a proper server with room for 40+ HDDs to move my media server to and have RAID 1. I know a lot about PCs and software, but when it comes to server hardware I have no clue what I’m doing. How would I go about building a server that has access to 40+ RAID 1’d HDDs?
40 drives ? Why that is a huge amount of power , what is your space target
RAID 1 ? With 40 drives ? That would be absolutely stupid you want to use RAID 6 or 10 so you don’t waist 50 % of your space with RAID 1. Or some other N+2 disk redundancy.
Have you considered how much power such a large setup will need?
I’ll have to watch a video on it later, I assumed having a 1:1 backup was the most efficient backup method possible without compression. I don’t plan on utilizing every drive at once, and I don’t plan on having more than 20 to start with, but it won’t be much more than I already have, so I should be okay to start. I just want to make sure there room for expansion in the future. I don’t need all 40 immediately. My UPS will tell me how much power I’m drawing, right?
RAID isn’t backup it is high availability.
RAID is not a backup, please don’t use RAID as a backup.
You need to research raid 1,6,10 and zfs first. Make an informed decision and go from there. You’re basing the number of drives off of (uninformed) assumptions and that’s going to drive all of your decisions the wrong way. Start with figuring out your target storage amount and how many drive failures you can tolerate.
40 HDD is a lot.
Check out 45 Drives. They have a homelab focused offering that has 15 bays https://45homelab.com/#product
To get 40 hard drives, you’d be looking at something like their Storinator S45 https://www.45drives.com/products/storinator-s45-configurations.php
With that many drives why raid 1? You could do a few raid z2 or z3 vdevs in truenas.
Doesn’t that keep more than two copies? RAID 1 is expensive enough as is. I just need to be able to pop in a replacement drive if one fails so I don’t lose data.
