Earlier this week I was having a conversation with a network engineer for a large bank. His full-time responsibility is managing servers. He readily admitted that the most common problem he encounters these days is failures of the raid controller. When that happens you have to replace with an equivalent controller. If you can't none of the data on the drives will be accessible. Some people have made a business out of stocking old RAID controllers and selling them for big bucks. * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *

The comments are more interesting then the article.

[CGUYS] RAID's days may be numbered.
I stayed out of the last fight over RAID. I have no great love for it, and have had more than one oops with RAID, but I also know that lots of folks especially those in IT desire it. Apparently it's not just those using Reiserfs who suddenly find that an Array has to be rebuilt or that something actually appears not to have been written when it should have been. I don't use RAID at home, instead relying on backups on external drives which I occasionally test by taking a blank drive and seeing if I can restore everything on that drive. Being semi-paranoid, I also regularly back up data and pictures on DVDs. So far I haven't lost anything with this going on but I know that eventually something will go wrong. * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *
