In my humble opinion software raid is much safer than hardware raid if you are worried about controller failure or disk failure. With Software raid: 1) Any compatible controller will do. On the Motherboard, on an add-in card, in a new machine. 2) You can mix drive types, even drive sizes. 3) You can span controllers. (your current setup kills the raid if one controller dies) 4) Replacement controllers don't get harder and harder to find as time goes on Also, but not related to failure issues 4) Software raid improves as you upgrade the server - its not stuck at the speed you bought it 5) imposes very little load on the server (contrary to the FUD of the past) 6) easily configured in modern Distros, especially when your machine has 4 or 6 SATA ports. Yast does it. I've been the 3Ware route. Its nice in that if done correctly your computer OS need never be aware that a raid is involved at all. But over the years I have migrated to software raid for the ease of maintenance, migration, disk replacement. I've used raid controllers with their raid software turned off (via jumpers) just for the ports in the past, but my current servers have scads of Sata/eSATA ports making this unnecessary. I still endeavor to put the drives of an array on different controllers although I've never seen any measurable difference in doing so. Non of this is helpful in your current predicament, just a philosophical discussion. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
