This Info comes up from Vroom! blog from VMware.
It seems that the first tests from VMware partners comes up and shows that having some monster VMs can be beneficial for applications like SAP. In fact, Fujitsu has tested 2 systems, one which has been running on physical server, and another one within VMware vSphere 5 with a VM configured with 24 vCPUs….
The first SAP sales and distribution (SD) benchmark on vSphere 5 has been published. It takes advantage of the new larger VM support in vSphere 5 to reach 4,600 SD Users and 25,150 SAPs with a 24-vCPU VM running on a Fujitsu Primergy server. This is the largest SAP 2-tier benchmark on vSphere as of today.
Fujitsu took the extra step of using the same server and test configuration to publish a non-virtualized result. Comparing the two tests shows that virtual is only 6% lower than native. This is a result of the hard work that was put into vSphere 5 to optimize its performance and shows that large 24 vCPU VMs can have performance very close to native.
The new VMware vSphere 5 proves that it is:
– Can run very large virtualized databases
– Very low overhead – just 6% compared to the same native system
– Does support large SAP systems
Some details from the test configuration:
The tested OS was running Suse Linux Entreprise Server 11 SP1.
The SAP ECC 6.0 with EHP 4
Fujitsu Primergy RX300 S6 with 2 x Intel Xeon X5690 processors and 96 GB RAM.
MaxDB 7.8 for the database. SAP
You can have a look at both certification documents here and here . The certificates are 2011027 and 2011028.
