Re: Oracle 10g RAC on Linux - hardware confusion #@$!

I couldn't find any readily available docs on the powervault 220, but any direct attached SCSI array will work, on the condition that one of your server nodes changes their SCSI initiator id. A better solution is either firewire or little Fibre channel arrays.

In fairness to Oracle, the type of clustering they do requires that you have some kind of reasonable storage on the backend. Deploying RAC is difficult and generally expensive and the only real reasons to do it are to improve scalability, improve reliability, and reduce hardware cost. Given that RAC is more appropriate for enterprise systems, having a certain minimum size/scope of storage on the backend doesn't seem too unreasonable.

For development/testing environments, use firewire. It is very stable and functional, though I wouldn't bet my business on it :)

Thanks,
Matt
