IT was something like a large RAID 5+0 (0+5???) and would send an alert when a drive died or started getting errors, and the bad drive's caddy would be flashing read instead of steady green. I just remember thinking that I'd never used a drive array that was taller than I was before that. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
