Understanding and interpreting the VMmark benchmark
Introduction
Using virtual machine technology to run multiple virtual servers on a single physical server continues to grow in importance as
the IT industry searches for ways to more efficiently use hardware compute resources in the data center.
Traditional benchmarks are typically designed to test the performance and scalability of a server performing a single large-scale
task such as database serving or web serving while running under a single operating system. Results of these types of
benchmarks, however, do not provide a reliable indication of the server‘s ability to scale when running multiple virtualized
systems in a virtual machine environment.
VMmark, which was developed by VMware and introduced in 2007, was the first and is still the dominant benchmark
designed specifically to measure and compare virtualized system performance for servers.
Structure of the VMmark benchmark
As a VMware product, the VMmark benchmark works solely with the VMware ESX hypervisor; therefore, it cannot be used to
measure the relative performance of other VMM solutions such as Windows Server 2008 Hyper-V or Citrix XenServer. VMmark
can be used to gauge the relative virtualization performance of different server platforms when running the ESX hypervisor.
The Tile
VMmark’s basic unit of work
VMmark uses a set of six virtual machines, each running a particular operating system and application workload, to define its
basic unit of work
the tile. Table 1 shows a detailed breakdown of the operating systems and common data center
applications that comprise each of the six virtual machines in a tile.
