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!

Another Snapmanager Question (MS Exchange, VMware

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

This way you have your snapshotted LUNs and you can back them up any way you
like.
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 ;)
