Re: how to setup my StripeSet ?

first off, you probably don't want RAID 0 unless you have a very thorough back-up procedure and can afford downtime; because (obviously) if you lose one disk your entire server goes down. if possible, try and get more disks such that you can at least mirror your online redo logs. a best case scenario would allow for RAID 10 (mirroring + striping) for all the data files. also, read the oracle docs (http://technet.oracle.com) for information on separating different types of data files.

the proper setting for your stripe size depends on the application. a simple rule of thumb is ensure that read/write operations will be distributed against multiple disks since performance will increase nearly linearly as disks are added.

there is a nice overview of physical storage concepts at http://www.oreview.com/9801shrp.htm.
