[linux-lvm] Core questions from a LVM neophyte...

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.
