Hi,

I have a Compaq Proliant server with 5x4.3gb RAID disks. I have decided to configure them to Raid-1 (mirrored set) for redo logs, control files, NT OS, and oracle software, and Raid-0 for data files (RBS, data, temp, ...).

Now my question is: how many PHYSICAL disks should I create? I know Oracle recommends as many physical disks as possible. However, according to my research, some people say since RAID-0 stripes data accross several disks, there is no need to create independent disks, i.e. one large disks with several logical drives will be good enough. Which one is correct?

Any suggestions will be appreciated.

S.H.
