I am looking for a SAN solution, but can't afford even entry level solutions. Basically, the SAN is for development and a proof of concept product. The performance doesn't have to be amazing, but needs to be functional.
My buddy says we should just setup sotware RAID and software iSCSI in Linux. Essentially I have a spare server with dual Xeon processors, 4GB of memory, and (2) 500GB 7200RPM drives. It's a bit old but working.
I am sure there is reason people don't do software RAID and iSCSI, but will performance be usable? Thinking of configuring the drives in RAID 0 (for performance).
