A number of years ago, the Taneja Group started testing workload density among competitive hypervisors, and labeled it VM density – a measure of how many VMs similar systems can run without compromises in performance or usability.

When poor VM density makes it necessary to add more servers and hypervisors, it can add up to many thousands of dollars and dwarf hardware costs. Meanwhile, with more servers/hypervisors comes more complexity and management overhead, which can run into the tens of thousands of dollars per server.

Superior VM density can easily add up to hundreds of thousands or millions of dollars in savings for a business. Check out this objective analysis of HP 3PAR Storeserv as the VM density and potential cost savings are revealed.
