If you install a Unity Connection cluster on two virtual
machines, the virtual machines must not be on the same blade. Ideally, the
virtual machines are on separate chassis.
If you install a Unity Connection cluster on one virtual machine
and one physical machine, you should configure the virtual machine to match the

space on the physical server and virtual machine do not match, Unity Connection
uses the smaller disk size to determine when the disk on which messages are
stored has reached maximum capacity.
For information on installing Unity Connection on physical hosts
