It's normally the case that getting a hot spare automatically attached = should be fine, but not if you also have the box go down entirely and need to = fsck. I'm more used to needing to explicitly physically swap out a failed = mirror component, in which case one can make sure the system is OK before the replacement = drive goes in. > [ ... ] >>> Before people tell me to use an UPS, i used a UPS but the damn thing = gave >>> way itself.

APC is decent for desktops, but I'm dubious about them when it comes to = entire racks or a DC. I like Leviton's PDUs/MDUs and TVSS; for a medium-sized UPS = (10-40 kVA) Liebert and PowerWare (now Eaton) were good. Liebert's PDUs are also = pretty good. Regards, --=20 -Chuck PS: I ran a small DC in NYC with a 20kVA PowerWare 9330 behind a Leviton = 57000 TVSS; the Cupertino locals have ~650kVA worth of Bloom boxes and a Cummins = diesel genset as a backup just for this building.
