How Much Energy Is Your Server
Using? And How Much Could an
Energy-Efficient One Save You?
Exploring the Results of the First SAP Server Power Benchmark

With rising energy costs and more companies
running multiple servers to support the business,
switching to more energy-efficient servers seems
like an obvious way to cut costs. But how can a
company be sure that the energy-efficient server
it chooses is truly a sustainable one?
To help, SAP, in close cooperation with its partners, introduced the SAP server power standard
application benchmark, which tests a vendor’s
server, allowing that vendor to demonstrate the
server’s efficiency — and enabling customers to
evaluate just how sustainable a server is before
Note that this benchmark is unlike previous
SAP standard application benchmarks, which
focused on measuring server performance and
scalability, with no care given to potential energy
consumption or system costs. The SAP server
power benchmark measures — and shows companies the balance between — the two
“contradictory” targets of low energy consumption and high performance.
We have covered this new benchmark in a previous Performance & Data Management Corner
Fujitsu’s SAP server power bench-
mark achieved an average con-
sumption of ; 8. 3 watts to obtain
a throughput of ;,000 SAPS.
column,; but now let’s explore the results from
one of our partners, which has earned the first
SAP server power standard application benchmark: Fujitsu.;
A Detailed Look at Fujitsu’s
In its SAP server power standard application
benchmark, Fujitsu tested the Fujitsu PRIMERGY
RX300 S6 server. (See Figure 1 on page 86 for
a look at the software and systems involved in
this test.) Fujitsu used the following elements
to achieve its certified benchmark result of ; 8. 3
A modern, multi-core CPU that enabled fea-
tures like speed stepping, turbo boost, and
hyper threading. These features help ensure
high performance while using low levels of
electrical power consumption.
Efficient, low-voltage main memory modules.
An optimized memory size, which results in
less power consumption. With 7; GB of main
memory, the memory was smaller than that
typically used in other benchmarks with this
number of users — here, 4,700 sales and distribution (SD) benchmark users.
