TEST REPORT

FEBRUARY 2006

SPECjbb2005 performance and power

consumption on Dell and HP blade servers

TEST REPORT

JUNE 2007

KEY FINDINGS

z The blades in the Dell PowerEdge 1955

Blade System achieved better

performance/watt than the HP BladeSystem

c-Class at every configuration we tested

(see Figure 1).

z With 10 blades installed in both systems,

the blades in the Dell PowerEdge 1955

Blade System achieved 8.73 percent higher

performance/watt than the HP BladeSystem

c-Class.

z At the maximum blades configuration, the

blades in the Dell PowerEdge 1955 Blade

System achieved 4.17 percent better

performance/watt with 10 blades installed

than the HP BladeSystem c-Class did with

16 b

lades installed

Executive summary

Dell Inc. (Dell) commissioned Principled Technologies

(PT) to measure the SPECjbb2005 performance per watt

of the following dual-socket blade servers:

z Dell PowerEdge 1955 Blade System

z HP BladeSystem c-Class

In this section, we present the best results for each server.

For complete details of the performance of each Java

Virtual Machine (JVM) by warehouse for each server, see

the Test results section.

Figure 1 illustrates the performance/watt for each of the

blade server systems by configuration. Higher results

show better system performance/watt, which lets a system

perform better with less power.

We calculate performance/watt by dividing the

SPECjbb2005 result by the average power consumption in

watts during the period the system achieved peak performance.

Figure 1 shows the blades in the Dell PowerEdge 1955 Blade System achieved better performance/watt at every

blade configuration. With 10 blades installed in both systems, the Dell PowerEdge 1955 Blade System achieved

8.73 percent higher performance/watt than the HP BladeSystem c-Class. At the maximum blades configuration,

which is the total number of blade servers installed in the chassis, the Dell PowerEdge 1955 Blade System

achieved 4.17 percent better performance/watt with 10 blades installed than the HP BladeSystem c-Class did with

16 blades installed.

Furthermore, the Dell PowerEdge 1955 Blade System achieved 6.42 and 5.88 percent higher performance/watt

than the HP BladeSystem c-Class in one- and two-blade configurations, respectively.
