Personally, I haven't had any issues, but then again on the ZFS scale of things, both my current pool size (2 TB) and projected pool size when I add more disks (6 TB) is pretty small. If this was a heavily used machine with a 10 TB pool or bigger, I would definately give strong consideration to ECC. > For the records, I've found an interesting and very recent post about > someone running OpenSolaris on this Supermicro motherboard [1]. =A0He use= s > a thumbdrive for the operating system and with four drives connected > onto it, the whole system sucks 41 watts when idle (27 without any HDD, > which is twice as the Intel D945GSE The power draw (from the wall) for the Supermicro X7SPA-H without any disks attached is as following: 26W - During boot. 24W - IDLE at console 28W - Full load This is with a 80+ rated Corsair 400CX PSU. Sadly, I did not have the opportunity to measure the power draw with powerd enabled. The D945GSE is unsuitable for use as a ZFS NAS due to it's severe feature limitations when compared against the X7SPA-H, of biggest concern would be the limitation of RAM, followed by the amount of native SATA ports, followed by the fact that you only get a PCI-E x1 (both physical formfactor and speed-wise) slot for expansion, while most controller cards are either 4x or 8x, meaning they simply wouldn't physically fit into the slot. Singlecore 1,6Ghz Diamondville Atom VS Dualcore 1,66Ghz Pineview Atom 1 RAM socket supporting a max of 1GB VS 2 RAM sockets supporting a max of 4GB (note that X7SPA-H uses SO-DIMMs, not regular DIMMs) 2 SATA ports vs 6 SATA ports 1 Realtec NIC vs 2 x Intel NIC PCI-E x1 Slot VS PCI-E x4 Slot (in x16 form factor) for expansion - Sincerely, Dan Naumov
