Hi, I'm looking for comments on the feasibility of using RAID arrays or similar "protected storage" with AFS file servers. I've looked through the old info-afs messages, and I've found two previous discussions on this topic. The first was a general "can it be done?" question like mine, from October 1992. The answer then was that the SAS folks were using RAID 5 arrays on HPs with no problems. The second was a more philosophical discussion from last June about how RAID writes are too slow and RAID would be best suited for read-only applications. But I can replicate most of the stuff that I would classify read-only, and get higher availability without forking over the dough for a RAID controller or two. Is anyone currently using RAID arrays on their AFS servers? If so, did you have to do any afs tweaking, or was it plug and play? And are you satisfied with the performance you're getting? Any server configuration you can give, platform, os, afs version, drive sizes, RAID controller manufacturer, enclosure manufacturer, etc. would be great. Thanks, Steve Mattson University of Michigan
