Presuming a DBA is forced to use RAID5, what elements of tuning become
irrelevant? (in the sense that if you're stuck with RAID5, warts and
all, then trying to tune X, Y, and Z would be a waste of time /
ineffective).
Load balancing files would be one thing.. no way to put indexes and
tables on different disks (ditto redo log file members, etc) with one
massive RAID5 volume.
What about fragmentation and coalescing? Are these still a concern for
tablespaces located on RAID5 volumes?
Has anyone written an article about Oracle and "living with RAID5"? I'm
finding that a customer has several Oracle databases on systems with
nothing else but RAID5 storage for everything.
Thanks very much.
