Just to re-iterate, HPs Virtual Replicator does this. (IIRC $10K) They like you to put a MSA-1000 FC Array behind your VR server (IIRC $15K entry), but it supports/exports any FC array or local disk solution. It does not provide any RAID aspects. If you want to know more, e-mail me off-list. Greg (HP certified SAN architect) >> I'm interested in a block level export.
