RAC Test System

I will be responsible for implementing RAC on one new system in our organisation. However, I've never played with RAC, so I want to have some simple but working test enviroment to learn how this beast works. Because one node only setup from oaktable.net is not enough for me I thought about using two PCs with Linux on them. However, problem is with shared storage.

Can someone of you here suggest some feasible and not very expensive solution. The only one that I can imagine right know is to use two SCSI cards with one disk drive. However, that doesn't looks very nice. So any better solution is really appreciated.

Thanks
