Licensing Question for vSphere 5

[VCP2009]

My company currently has both Standard and Enterprise licenses. With the new vRAM structure can a combination of these licenses be used within the same cluster? For Example 1 Enterprise license in the same cluster as two Standard licenses?  Would the entitlement work out to be 64 enterprise and 64 (2) standards (assuming single socket) for a total of 128 vRam usable? I know this isn't best practice with DRS and all but it is what we have for one of our small clusters.

Thanks,
Jeremy

vRAM entitlements from different versions of ESX cannot be pooled together. Only the same versions can be pooled.

In your example you would have 128GB of total vRAM entitlement, however you will have 2 separate "islands" of vRAM entitlement. 64GB for the 1 standard license and 64GB for the 2 standard licenses. The enterprise licenses would be 1 group and the standard licenses would create another group. And it goes without saying that the hosts licensed with the enterprise licensing are the only hosts that would get the enterprise features.
