Du mener hot spare?

Ja :-)

Med RAID 6 kan man miste to diske, mister du to diske
på RAID 5 imens den er i færd med at genopbygge på spare
disken har man et problem.

Det er slf. rigtigt. Men er der nogen gode retningslinier for hvor
store/mange diske der skal til før RAID5 ikke er "nok"? Og nogen
erfaring med hvilken performance pris man betaler?'

Det sidste kommer jo nok an på anvendelsen af disken, altså på
applikationen - random writes eller sekventiel læsning. Vi har mange
skriveoperationer.

Med venlig hilsen / Best regards
