Cheap shared storage for small RAC?

I am looking for ideas and/or recommendations about network appliance (iSCSI?) or may be external storage built of ATA/SATA/SCSI hard drives, does not really matter as long as it performs half decently, hopefully certified for Oracle 10g RAC.

The trick here should be three fold:

• It should be relatively cheap, (cost less than $6K; lesser - better),
• It *must* run reliably in 2 node Linux cluster (which I can not say for FireWire based RAC I've tried) ,
• At least one person should be willing to say magic words: "Yes, I have/run such a beast at my place and it works just fine".

Any pointers on fitting vendors/models - greatly appreciated.

P.S.

Goal of the above is to assemble small RAC just a notch above toy-systems for development.

This is probably not of interest to wider audience, therefore please reply directly (to keep "noise" on the list down).
