Sorry, bit-'o-confusion there. I'm using raidz2 with a 12 disk pool, and have been happy since some of the performance improvements around snv_86. As always, YMMV.

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. On Aug 21, 2008, at 1:39 PM, "Andrew M.

It's even to the point now where the installer will make the mirror for you (atleast on nevada, don't know about indana) Also, to respond to Ross, there was a vary good post here a while back indicating that adding "set sata:sata_auto_online=1" to /etc/system made the device come online as soon as the port was activated, I have been much happier with my raidz2 array since adding that.

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