"Am I smoking pot?"
No, you ain't Chris.
I asked the same question a few days back on twitter.
The only reason I can still see the need of a SAN in a converged stack is to provide independent scaling of server unit's vs disk spindles (one to many, many to one etc) within the individual converged stack.
However, this adds major cost and complexity and given the lowering cost of both disk and servers, the question is -is it worth it? Why not overprovision either (server or disk) side and use as fit togher with a software virtualization layer?
