Q: How should virtual server migration between the enclosures be handled?
You can migrate the virtual machines between blade servers between enclosures using tools like VMotion. What it's going to depend on is that the SANs are presented and the network's presented to the different blade servers, so you've got a transparent service viewpoint to the end user. That should be able to transfer blade server one in enclosure A to blade server two in enclosure C. For virtual server migration you need to make sure that the logical components -- the network, the SAN -- are in place to do so.
