I'm looking for ATA/SATA-based RAID systems and find the Apple Xserve
RAID to be very interesting. One issue I have not yet been able to find
out is whether it is possible for a RAID 5 set to use more than seven
drives.
I know that it would be possible to use a RAID 50 configuration using
software RAID on the server, but this does not look like the optimal
solution to me. Amongst other reasons because I suspect that this would
mandate the use of two instead of one hot spare (one for each
controller). Also I am not sure about how much additional load this
would put on the server and whether all operating systems come with
stable software RAID implementations (we want the RAIDs to run at least
on servers using Linux and Mac OS X Server, possibly in the future on
Windows and FreeBSD as well).
With kind regards
Piers
