The first SAP Three-Tier SD benchmark on vSphere 4.0 was recently completed and published by Fujitsu. The published results of this test highlight support of an impressive 16,000 users with a SAPS rating of 87,800. This shows that large numbers of SAP users can be supported in a virtual environment spread across many hosts while providing good performance.
Eight Fujitsu Primergy servers with Intel Xeon 5500 series processors were used to host 14 application server VMs and one database server VM. The details about this test are in a benchmark report that was put together by Fujitsu and VMware. The official SAP benchmark site also has added this new result to the Three-Tier SD Benchmark results.
