You could get a $200 cheaper, more power-efficient, and more performant config by buying a high SATA port-count desktop-class mobo instead of a server one + AOC-SAT2-MV8. For example the Abit AB9 Pro (about $80-90) comes with 10 SATA ports (9 internal + 1 internal): 6 from the ICH8R chipset (driver: ahci), 2 from a JMB363 chip (driver: ahci in snv_82 and above, see bug 6645543), and 2 from a SiI3132 chip (driver: si3124). All these drivers should be rock-solid. Performance-wise you should be able to max out your 8 disks' max read/write throughput at the same time (but see http://opensolaris.org/jive/thread.jspa?threadID=54481 there is usually a bottleneck of 150 MB/s per PCI-E lane, this apply to the JMB363 and SiI3132). Downside: loss of upgradability by having onboard SATA controllers. No onboard video. And it's an Intel mobo. Intel's prices for low-power processors (below ~50W) are higher than AMD's, especially for dual-core ones. But something only slightly more power-hungry than your 45W AMD is the Pentium E2220 (2.4GHz dual-core 65W). Most likely your NAS will spend 90+% of its time idle so there wouldn't be a constant 20W power diff between the 2 configs. What I hate about mobos with no onboard video is that these days it is impossible to find cheap fanless video cards. So usually I just go headless. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
