Virtualized Hardware and Resource Oversubscription
--------------------------------------------------

It is recommended that no more than two Unified nodes and one WebProxy
node be run on a physical server (VMware server) and that the disk
subsystems are unique for each Unified node.

VOSS Automate virtual machines should maintain a 1:1 ratio between virtual
RAM and Disk hardware and physical hardware, in other words:

* 1 GB of virtual RAM (vRAM) must map to 1 GB of physical RAM
* 1 GB of virtual Disk (vDisk) storage must map to 1 GB of physical storage

For virtual CPU (vCPU), hyperthreading is supported.
