A question about "battery": is it still an argument if you system is backed up by an UPS? I thought the batteries on controller cards were paramount only on systems that are not protected by a convenient UPS. Wrong?
The idea is, I assume, that battery backed hardware raid detects that the power died and commits everything to disk before finally powering down the HDs. An UPS will keep the entire computer running till it finally gives up, or either the human or software powers it down before the battery runs down. Not really the same thing, but both avoid disasters. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
