I use Postgres w/Vinum setup to mirror 2 9gig SCSI Cheetahs and I have no complaints. I bang on the db quite a bit (moderately busy site and tons of data analysis) and performance is great. Ultimately I am going to slap a hardware RAID card in there (need the immediate failover) but right now software wise performance is great. I'd probably only recommend doing mirroring in software though, RAID-5 is going to eat up alot more CPU and disk writes. -- "Don't 'kill -9' the SYSVMSG" [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
