That was actually me talking about svm :)
What would be the ideal zfs layout for 15 disks if I want 13 disks
worth of space usable? I hear 5-6 disk zpools are the largest
recommended due to peformance or something. I'd be willing to go with
n-2 for "dual parity" essentially.

Wow, thanks for the quick reply. I will look to see the dBA for that<br>
PSU. If it's low enough, I'll go with that one.<br>
<br>
I'll be using an Athlon 64 that has lower power requirements, a mobo,<br>
a PSU and a boot drive. So total will be 16 drives + CPU/mobo/RAM +<br>
PCI-X card + optical (as needed) + fans. I have this mobo/CPU/RAM<br>
combo already at home now running snv_94 + ZFS and it works well and<br>
is pretty quiet. Current config:<br>
<br>
Case: Antec P182<br>
Mobo: Asus M2N-SLI Deluxe Aud/2GbLan/SATA/RAID/1394 ATX<br>
CPU: Athlon64 X2 Dual Core 4450e 2.3GHz 2x512k 45w Retail<br>
RAM: 4GB(2x2GB) DDR2 PC6400 800MHz Matched Pair Kingston<br>
Optical: LiteOn 20A4P 20x IDE DVD+/-RW<br>
Video: Asus GeForce 8500GT 512MB TV-Out/DVI Silent Edition<br>
Boot Drive: Seagate 320GB 16MB cache IDE<br>
PSU: CoolMax PS-V500 500W<br>
6x Seagate 1TB 32MB cache SATA2<br>
CPU Cooler: Zalman CNPS9700 19.5dBA heatsink/fan<br>
<br>
However I only have 7 drives total in that box if I recall + optical.<br>
I didn't figure I needed to shop for a special-needs PSU for that one.<br>
However for these larger disk quantities I wanted to make sure I could<br>
do it all :)<br>
<br>
This time around, I can use a SATA boot disk (or two, if the PSU will<br>
support it and mirror it using SVM?) since I will have the extra<br>
onboard SATA ports. The current config I used only onboard SATA ports,<br>
so I had to go back to IDE for my boot disk.<br>
<br>
I plan on using the same config above (Mobo/RAM/CPU/Video/Optical/CPU<br>
Cooler possibly too)<br>
