RAID INSTALLATION

I would like to implement a raid storage system on a Compaq 7000series server but don’t know how to. The server has 3 x 18.2GB SCSI hard drives. I have just installed Windows 2000 on it. The processor is 1.4Ghz & has 1Gb RAM.

What RAID level mustI use and how do I install.

The server shall be running an Oracle DBase7.0 as well amongst other things.
