64GB Page File For Exchange 2010

Hi,

I usually put larger page files on a separate disk, which is roughly 1.5x the size of the physical memory.

I'm using a Poweredge with 80GB RAM, of which 64 are allocated to Exchange. I've added a dedicated page file disk of 96 GB, but am not sure whether this is the best way to go. I couldn't find an official vmware recommendation on the page file.

Please advise.

Thanks
