Unfortunately, FreeBSD has some issues with low memory handling that make FreeBSD/i386 a bad choice for ZFS. You would be far better off running amd64 with as much RAM as you can fit onto the board. (And this is one case where you want amd64 even if you don't have >4GB RAM). Note that this doesn't mean you can't use an Atom - some Atoms include EM64T - you just need to check. IMO, the biggest disadvantage of using an Atom in a ZFS NAS is the lack of ECC support on the Atom. ZFS can detect bitflips in the I/O sustem but you can still get screwed by a bitflip in RAM. >I'm still not sure about which motherboard to buy actually.

I'd recommend against buying anything with the Atom combined with a 945. Whilst the Atom is low-power, the 945 isn't. That is also an older motherboard using an older, superseded Atom. I suggest you look for motherboards built around the new Pinetrail Atoms (which _do_ support EM46T and hence can run amd64). Supermicro make a number of potentially suitable boards: http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPA.cfm this is pricier but supports remote management - other options at: http://www.supermicro.com/products/motherboard/Atom/ If you want an Intel MB, search for BOXD510MO Note that I'm not sure how well FreeBSD's X.org supports the Pinetrail yet. There have been some commits but I don't know if support is complete. --=20 Peter Jeremy --tjCHc7DPkfUGtrlw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAku5MYIACgkQ/opHv/APuIdzowCeIBwjxQrbHFWQCeP83N6Qwfa7 yYAAoLjlszJPezdKyuaeKuRIXt0HxdbK =ETyd -----END PGP SIGNATURE----- --tjCHc7DPkfUGtrlw--
