I have an HP DL380G4 w/ 3Gb of ram and a slow MSA15 (SATA discs to a single u320 interface). I was using this with 10u7 for a smb over zfs file server for a few clients with mild needs. I never benched it as these unattended wkst''s just wrote a slow steady of data and had no issues. I now need to use it for backup storage and noticed how absolutely bad the performance is. Just as a non technical way to grasp how bad, a dd of 4g from /dev/zero on the root rpool in a mirrored u320 pair of 72g discs on the Smart Array 6i takes ~1.5 minutes. The same dd on a RaidZ2 with 6 discs all exported as simple volumes on a Smart Array 6400 controller takes almost 20 minutes? With windows installed on this aging server, the times are nearly identical. The data I intend to write out to this machine will be bacula disk volumes and hence it needs to sustain large amounts of streamed data so even a zil I don''t think will help as the file''s will be 300-400G :) What''s my next best option? Thanks! jlc
