Some RAID cards allow you to choose a JBOD mode, but this shouldn't be trusted too well (research needs to be done on the specific card model on forums), as depending on the card, some do not give the OS bare direct access to the blocks and the SMART data, both of which are required for a good ZFS implementation. By far the best solution is to use ZFS on JBOD (Just a Bunch Of Drives - means bare drives, without any hardware RAID) / bare drives (an HBA). In short: although technically you could use hardware RAID, you probably shouldn't the worst possible thing would be to use it with ZFS as well.

Why do they seem to break so frequently? Because people use software RAID (mostly ZFS) on top of these cards, which poorly handle the monumental amount of IOPS that ZFS issues. The simple reason why everywhere they tell you to forget about hardware RAID is that you're not likely to find the same replacement for the RAID card when it breaks, therefore all your data would become inaccessible. Indeed, most servers come with a RAID controller technically you can run anything you want on it, but, as you pointed out yourself, it is a terrible idea to run TrueNAS on it. Great project you have in mind one thing on the refurbished enterprise stuff: yes, they can be great deals, but it's mostly old hardware, so be aware that they may be inefficient, have atrociously slow POST times, and may require specific hardware for compatibility (i.e. And that brings me here, there are a couple of ways we can approach this problem, but I don't have enough understanding to make a decision, so I have a couple of questions I've also read that Non-raid, also won't work since it doesn't fully expose the drives like if they were connected directly through SATA. From what I was able to gather online, this means I can't run FreeNAS on top of it, and you can't disable the raid controller since the drives are connected through it. The only issue we have is that all these servers come with a raid controller. So I don't see any major disadvantages of using hardware raid instead, but just woudnering if I am missing something important. It's my understanding that FreeNAS will handle the whole "network storage" part but from what I can see it's also not that hard to do it yourself on Linux. Hardware raid should be easier to set up than software raid. From what I understand as long as the processing power is not very low, software raid should be a little better than hardware raid, but we are not very concerned with minor performance differences. Does that mean I can run FreeNAS on top of it or does it mean something else?Ĭould I just run hardware raid? I am trying to figure out the difference between FreeNAS and hardware raid in our specific use case. Some controllers specify that they are "software raid enabled" like the PERC S110. Will FreeNAS/TrueNAS work well if I run RAID-0 on the hardware controller?
And that brings me here, there are a couple of ways we can approach this problem, but I don't have enough understanding to make a decision, so I have a couple of questions:Ĭould I just run RAID-0 and have each drive as a separate volume? I've seen this a lot online but haven't seen a breakdown on how well this works. It also does give me the ability to use that server for some of my programming projects. There are many great choices that would work for us. Specifically, I am looking at sites where you can configure servers from refurbished hardware. I was able to come up with a build for this fairly easily, however, this is when used server hardware caught my attention. Aiming to get around 4TB of useful storage at the start, and expand later if needed. Our budget is around £600 including the drives.

We originally were looking just o build a PC with some NAS drives, and run FreeNAS/TrueNAS on it. My dad and I are looking at building a NAS.
