Technology and architecture of HP ProLiant AMD-based 100 - series G6 (Generation 6) servers

Power and thermal technologies
HP engineers have developed a robust set of power and thermal technologies and components to
manage power within ProLiant 100-series G6 servers. The following technologies improve power
efficiency throughout the power delivery chain:
• Efficient power delivery
• Thermal sensors and fan control
• Processor management technologies
Administrators can disable certain components and capabilities within the ProLiant 100-series G6
servers or reduce capabilities to bring the components to a lower power state.
Efficient power delivery
Power supplies for the ProLiant AMD DL165 G6 server are not hot-pluggable. Common slot power
supplies are only an option in those G6 platforms supporting the common slot architecture. All 100-
series G6 servers use highly efficient power supplies and DC power regulators to deliver significantly
higher power efficiencies.
Industry standard power supply
The Pr
oLiant AMD-based 100-series G6 servers are not configured for common slot power supplies.
Instead, ProLiant DL165 G6 servers are equipped with the High-efficiency 500W multi-output power
supply that improves performance-watt ratio. This power supply is neither hot pluggable nor auto-
switching.
Thermal sensors and fan control
Thermal sensors and fan control in the ProLiant AMD based 100-series G6 servers remain unchanged
from the previous generation G5p servers.

Sensor data from the processor, hard drive enclosure,
and mother board provide thermal information to firmware that controls fan speed. Fan speed is
altered to increase cooling based on the sensor data and location. If one fan fails, all the other fans
default to high speed in order to assure the server remains within thermal specifications.
PowerNow! technology
AMD PowerNow!™ technology with Independent Dynamic Core™ technology and Dual Dynamic
Power Management™ is technology that allows the processors to run dynamically at different
frequencies and voltages depending upon CPU computing demand. As a result, PowerNow! can
lower server power consumption without compromising performance.
AMD PowerNow! can be enabled on ProLiant AMD-based 100-series G6 servers through the BIOS-
controlled Dynamic Mode of Power Regulator for ProLiant, which does not require an OS driver.

The G5p platforms included performance and capacity enhancements over the G5 platforms. Those additions include
higher performance Quad-Core AMD Opteron processors, increased memory DIMM slot count by 2x and high efficiency
options such as processors, memory, and power supplies.
