Usability is probably the most difficult concept to define when talking about virtualisation and particularly OpenVMS and virtualisation.

For OpenVMS users, scalability has always equated with clustering and with a maximum supported 96 nodes in a cluster. “OpenVMS is the most scalable operating system on the planet” - is that still true today? Yes and no.
