Forgive me for asking a dump question .
I want to install Oracle 10g RAC for development with 10 users. The load will be light for the most part . I would like to do some minor performance benchmark in the future.

I have two pentiumIII computers running windows .( I can install Server 2003/XP). I can get better computers or more later.

What exactly do I need to buy for shared disk array? (Something cheap $300- $500)
Will any external hard-drive do? I have seen the OTN document for linux which is asking for a Fire-wire device.

Again any advice will help.

thx
