Although I am not really in the oracle field (NT Systems Manager) I hope someone can help with my query.

We have a oracle database that currently resides on an aging external Clariion Raid cabinet. The DB is spread over several disks configured as RAID 10 and RAID 1. This set-up was chosen several years ago as the best set-up for oracle to run.

Recently we purchased a new server with inernal RAID capabilities. As the exteranl cabinet is now quite old I would like to propose to our DBAs that the DB is installed on the internal RAID disks. However as there are only 8 disks (although more capacity) I do not think it is practicle to pick the RAID levels as described above. I would like to configure the hardware RAID at level 5.

What I would like to know is what is generally is the best RAID configuration for Oracle DBs is it striping/mirroring or can you use stripe/parity without major performance degradation Thanks in Advance
