The point is that you have to keep a hardware spare with hardware RAID. This can make things much more expensive. Also, software RAID is typically free, while a hardware RAID of similiar performance several k$, and you have to double that if you have to keep a hardware spare. A minus point that software RAID can write out garbage from bit-flipped RAM when the power goes out. This is more of a problem with some file systems (xfs?) than with others. Not a problem with UPS, though. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
