Dual Opterons for a ZFS server is probably overkill...there isn''t
anywhere near that much check-summing overhead! The second CPU expense is
probably better spent on RAM or better quality drives. Be sure to use
enterprise SATA for best RAID performance; besides, they aren''t much
more expensive.
If I had your requirements on a tight budget, I''d build from either a
nice used W2100z/W1100z [4-drive OEM support w/ latest BIOS] or get a new Ultra
20 [only 2-drive OEM - but space to mod]. Of course, you''ll probably
void your warranty modding an Ultra-20, but hey, you wouldn''t have much
of a warranty with a whitebox anyway.
Google for the ZFS wiki...you''ll know the one when you see it and
they''ve started putting in a few performance tuning settings.
Since I typically run mirrors I don''t have much direct performance
experience with RAIDz, but you may wish to simply make a RAIDz pool if the
performance is adequate and you desire more storage space.
