Example text

The virtual machine is turned off and its memory contents are stored in a separate file on disk. When the machine is returned to service, the memory contents are read from the file and the virtual machine returns to the state it was in before the move. When it comes to Exchange 2013, this is not supported. It is important to realize that when you’re running an Exchange server on a host-based clustering solution, you still have one copy of an Exchange server. That is, there’s redundancy on a host level, but not on the Exchange level.

Although small, there’s a performance penalty when the disk is expanding, however. More important, there a serious risk of overcommitting the underlying disk when you’re using this type of virtual disk. You won’t be the first, and certainly not the last, person to use a dynamically expanding disk to discover that it is completely filled and the virtual machines have stopped working. Therefore, dynamically expanding disks are not supported for running Exchange 2013 in a production environment, but for a lab environment it is a great solution, as it will save you a lot of disk space.

That is, there’s redundancy on a host level, but not on the Exchange level. If the Exchange server fails inside the virtual machine, you end up with a high-availability virtual machine and an unwilling Exchange server. If redundancy in Exchange Server is important, it is recommended you use guest clustering—that is, a database availability group in a host-based clustering solution. This way you can survive failures on a hypervisor level as well as on an Exchange level. Related to this, I’ve received several questions regarding the Hyper-V replica, and if this is a useful solution for Exchange Server.
