Even with a primary UPS on the *entire PostgreSQL server* does one still need, or even still recommend, a battery-backed cache on the RAID controller card? [ref SCSI 320, of course] If so, I'd be interest in knowing briefly why. Thanks. -----Original Message----- ===snip=== ... every server I've run PostgreSQL on has been burnt in for at least a week of heavy testing, and they've all had SCSI drives, and if they had RAID controllers they all had battery backed cache. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
