Re: RAID 1 or RAID 10?

It would be helpful to yourself most of all, and other people attempting to give advice if you could give some more information about "what type" of load you expect your oracle database server to be able to process. Tell us about the applications and their source (oracle, third party, in house written, etc), the number of concurrent users you need to support (initially and in the future, etc). What kind of queries will be running, OLTP or reporting based, simple selects against mostly single tables, complicated joins, etc. How much updating versus querying?

How much time do you have to do any benchmarking and possible reconfiguration of your storage?

With such limited information that you gave initially don't rely too much on advice from anyone. Most experienced professionals will strongly caution against implementing RAID 5 from the beginning not necessarily because it is a solution that will never work it certainly can in some cases but once you start heading in that direction it is often difficult if not impossible to obtain necessary downtime to go in a different direction.
