[plug] re: RAID5 & Hot Spares

[Jon Miller]

Sorry, there is a RAID controller card (ServerRaid-5i (IBM). The reason the question was asked was to find out if there are any issues in using raid5  in an Linux environment as well as if there were going to be any issues in Linux's ability to handle the changes if a hot spare was used.  Yes, the purpose of the raid is redundancy, also what must be taken into account is the load. This issue is handled by the processor(s) and memory.  Since this server is being used as a corporate database server serving information to 13 sites throughout Australia and Tasmania.  This seemed to be a viable solution.

Excuse me for being dense, but I thought that the whole idea of hardware raid
was that for all intents and purposes it appeared as a single IDE/SCSI drive?

Why is it using the CPU at all?

Unless you are talking software raid?
