[Build Log] The Rackosauras: FreeNAS Server and 12U SOHO Network Rack - Page 2

post #11 of 12
Your project is amazing. I was thinking about building something similar, but I bumped into a few issues...
1) The project costs roughly $8k. I get it that you're going for a 72tb build, but if I wanted to build a 12tb or 16tb system, "the rackosauras" would still cost way more than the $1.6k ixsystems' FreeNAS Mini. While freenas mini wouldn't come with your 32gb, it does come with probably everything else @ the "rackosauras".
2) What about hardware acceleration? I read ixsystems uses it for zfs encryption, but I couldn't find any specific hardware in it. How are you managing it with the "rackosauras"?
3) Why use two 500gb ssd's? if you're running only the system in raid0 on the ssd's, the drive size seems a bit overkill. But if you're storing files in it, you lose redundancy - this was kind of a mystery to me.
Well, other than these questions, I found your setup pretty awesome and would still be convinced to pursue a similar path!

Thanks, I appreciate the positive feedback.

The Intel Atom C2750 chip supports AES-NI, an encryption instruction set, which is the so-called hardware acceleration used by FreeNAS for ZFS encryption. Lots of Intel's chips support these commands now; it's not as special as it first was in 2013, but from everything I know it's definitely worth having for encrypted pools.

I used the SSDs because I had them available, and they seem to make good L2ARC cache drives. There's lot of explanations of ARC and L2ARC on the web, so a little research with Google ought to clear up the mystery.

FreeNAS and the ZFS file system are highly recommended if you are interested in building a robust NAS system. I'm really happy with the build, and it's working great for my requirements. But it's not the type of system everyone would want. After all, it's a rack-mounted server, and this thing isn't exactly small, it isn't exactly quiet, and it wasn't exactly cheap. It's the Rackosauras, what else can I say about it, I love it.
