SAP Performance on vSphere 4.1 with DB2 and SUSE 10

VMware published a paper
which shows that vSphere 4.1, out of the box, easily supports a
demanding SAP ERP installation by allowing administrators to either
scale up or scale out.

Scaling Up By Adding Processors

To
test scale-up performance, a similarly-configured physical machine and
virtual machine were used to see how many SAP users could be supported 
with one, two, four, and eight processors.

In
the experiments, a virtual machine with 8 vCPUs was able to support
approximately 1,200 users, achieving 93%-95% of the number of users as a
similar native test.

Scaling Out By Adding Servers

vSphere
4.1 can be scaled out to support larger user workloads.  A series of
tests with multiple virtual machines were run to compare the performance
of different scale-out scenarios with SAP.  The following graph shows
the scale-out test results and is highlighted by 16-vCPU tests.  These
tests showed that approximately 2,500 SAP users could be supported
using  four virtual machines each with 4 vCPUs, or 8 virtual machines
each with 2 vCPUs (for a total of 16 vCPU in both cases).

The
test results for both scale-up and scale-out show that vSphere 4.1
provides good performance for SAP in a variety of environments.  To read
