HP ProLiant Intel-based 100-series G6 servers

the Quick Path Interconnect speed. While the “Auto“ setting (which equates to 1333 MHz) is the

default setting, users have the option to manually lower the effective data rates to 1066 MHz or 800

MHz. This will save power, but may degrade performance. Administrators can configure the

maximum memory data rate through the BSU.

Managing I/O technologies

Disable PCIe 2.0

All ProLiant G6 servers include an option that allows all expansion slots to run at PCIe 1.0 speed

rather than PCIe 2.0 speed. Enabling this option saves power and provides backward compatibility

with cards that may not correctly operate in PCIe 2.0 slots. Administrators can control expansion slot

speed through the BSU.

Power Efficiency Mode

In ProLiant 100-series G6 servers, the BSU can enable three different settings for the Power Efficiency

Mode: Efficiency, Performance, and Custom. As implied, the Efficiency setting provides the greatest

efficiency, while the Performance setting provides the highest performance. The Custom setting is

simply any combination of user settings that do not match the pre-sets for Efficiency and Performance.

The Power Efficiency Mode directly effects the operation of select power features identified earlier in

this section.

NOTE:

Power Efficiency Mode is not supported on the DL1000 Multi Node server

Power Performance Benchmarks

The Standard Performance Evaluation Corporation (SPEC) is a non-profit corporation formed to

establish, maintain and endorse a standardized set of relevant benchmarks that can be applied to the

newest generation of high-performance computers.

SPECpower_ssj2008 is the first industry-standard SPEC benchmark that evaluates the power and

performance characteristics of volume server class computers. As of this writing, SPECpower

benchmark results are available for the ProLiant DL170h, the ProLiant DL380, and the ProLiant DL360

G6 servers (www.spec.org/power_ssj2008/results/power_ssj2008.html

). The test results show

performance gains achieved over the last generation of ProLiant servers.

NOTE:

These power performance benchmarks do not include servers using the Xeon

3400 series processor.

Server management and deployment

Every ProLiant ML and DL 100-series G6 server user has different computing requirements.

Consequently, the way in which customers manage, deploy, and control servers can differ. With

these requirements in mind, this section examines the following management topics:

 Systems management and monitoring
