Ok, this post is somewhat off the beaten path for this blog, but I've been dorking around with Solaris and ZFS for the last month or two as a replacement for my Windows Home Server for serving media. I'm still keeping the WHS server for backing up the PCs, but as a media server, the hitches casued by some of it's internal 'balancing' services was causing all manner of problems with high bit rate movies.
Using mostly spare parts, I built a X86 solaris box:
Quad core Core2
7 2TB 7200rpm drives
2 500GB 5400 drives
Antec Twelve Hundred case
The two 500GB drives are mirrored and hold most of the filesystems (and the OS, swap, etc.) I mirrored them using ZFS.
The seven 2TB drives are in a raidz2 configuration, which is much like raid6. Which is to say that I can lose up to two drives of the array and be OK. Gives me a net of 10TB.
I'm sharing the 'shares' pool via SMB across gigabit to the theater and my media machine, running XBMC, and so far, it's been awesome. Narry a hitch in sight. So far, so good.
