VMware VMmark
VMware VMmark is a free benchmarking utility that runs several workloads to measure the performance and scalability of multiple hosts in a virtualized environment.
VMmark runs several virtual machines (VMs) most commonly used in customer data centers, such as a mail server and a front-end Web layer, to produce a benchmark users can use to compare and contrast the performance of various hardware and appliances.
VMmark groups eight VMs into a tile and will run several tiles to utilize fully the resources of the servers.
VMmark also has the ability to measure power consumption through three different tests: performance only, performance with server power and performance with server and storage power.
The most current version is VMware VMmark version 2.5. VMmark was introduced in 2007.
