Hi All,

You'll probably get a number of responses, but here is my opinion. Based on nothing other than, well, my observations.
Advantages
Disadvantages
Better than a physical DM? Yes! From my perspective, there's no reason not to create a VDM and put your CIFS servers on it. It simply makes replication much easier to provide failover to a DR VNX. Even if you're not ever planning to do DR replication, simply having your CIFS servers on VDMs make it much easier to do hardware refreshes or major upgrades (e.g., moving VDMs between disk pools).
