This is really a great thing! J
For now, rdm in ESX have nothing to do with SD! They’re simply
raw space seen by guest using another virtual scsi controller exposed by
VMware. SD does the same but the guest cannot use FCP used by ESX servers! It must
use iSCSI!

Oggetto: RE: Another Snapmanager Question (MS Exchange, VMware ESX)
Mark,
SnapDrive 6.0 (soon to be released) will support RDM LUNs
(Physical Compatibility Mode) in the VMware ESX Guest OS. You can use
SnapManager for Exchange in the Guest OS and take advantage of all the
benefits and features as in a Physical Server.
Hope this helps,
Niraj

I'm afraid I wasn't fully clear. We just replaced a FAS940c by
a 3070c which is attached to the
(already existing) FC fabric. The FAS940c wasn't. That's why
we used iSCSI for our other
customers in the past. But now we would like to get the storage
from the FC fabric.
The problem, as I see it, is that afaik there is no way to
attach the fabric to the guest OS directly,
as you'd need a FC HBA inside the VM.
From the point of view of the guest OS, the storage that is
attached to the ESX looks just like an
ordinary hard drive. And I suppose SnapDrive won't work if
there is no LUNs for it to see.
However, to keep the Exchange storage groups consistent when doing
back up, you need to start
the backup from within the guest OS. We might use the NT backup
mechanism, though - but I'm
not yet sure if that's our best bet.

I hope so - but I figured I had better try to check the
possibilities there are so I'd be able to
ask the right questions ;)
Kind regards,
