It was officially announced that VMware has joined Microsoft's Software Virtualization Validation Program - known as SVVP. This is big news because it means that VMware hypervisors can become a validated and supported platform for Microsoft applications, including my favorite Exchange. The catch currently seems to be in the details. VMware ESX has not yet been certified (MS KB article with supported 3rd party hypervisors), although VMware has joined the SVVP.

I think that Microsoft and VMware coming to agreement on a process that leads to better support is a big win for their customers (Many of which are Dell customers too). Although the certification tests have not yet been run with ESX, it is my humble opinion that it is just a matter of time until it is a validated and supported hypervisor through the SVVP. The other big benefit here is that I will be able to remove some of the footnotes from my Exchange on VMware whitepapers once this is all settled.

Additionally the Exchange team blog has an excellent post with a link to a doc with their recommendations for running Exchange on Hyper-V which should be of great assistance to customers looking to do such a solution.
