Home -> Community -> Usenet -> c.d.o.server -> Re: RAID and Redo Logs
Ideal situation for redo log groups is to have two seperate disks on two
seperate controllers with one member of the redo log group residing on the
first disk while the other member of the redo log group residing on the
second disk. This is because the redo log files have a high level of I/O. If
you place the redo log groups on a RAID configuration, then you will take a
performance hit. For example, RAID5...All writes and reads involve a parity
caculation.
