Power supply support

The DL1000 Multi Node server supports both HP Common Slot and HP industry-standard power
supplies. Three Common Slot power supply options allow users to choose the best power supply for
each configuration to maximize efficiency and performance: 460 W, 750 W, or 1200W.
The DL1000 system can also use a low cost, industry-standard 750W power supply option that does
not support hot-plug or power capping functionality (it is not a "Common Slot" power supply).
For more information on HP Common Slot and Industry Standard power supplies, see the section titled
"Efficient power delivery."

Advanced Power Management

In addition to the efficiencies gained by the shared power infrastructure, the DL1000 system contains
advanced power metering and capping technologies. The Power Interface Controller (PIC) lets users
configure the system for full AC redundancy or AC redundancy with power throttling depending on
the system configuration. With the optional power capping mode, the DL1000 system can boost data
center capacity by reclaiming trapped power and cooling capacity.

Power Interface Controller

In order to maintain a pre-set power budget, the embedded Power Interface Controller monitors
power consumption and throttles processors and memory speed in each node within the chassis. HP
provides a simple command-line utility for reading and configuring the power control logic of the
server nodes. Versions are available for MS Windows Server OS (2003 and 2008) and Linux OS
with the requirement that the OS IPMI Driver be installed. Administrators can configure the controller
for the following Power Management modes:
• Power Control Disabled - No power throttling will occur.
• Maximum Performance with Redundancy (AC Redundancy with power throttling) - This mode is the
default setting and allows all nodes to share both power supplies and run at maximum performance
with no power caps. Power control logic will only throttle performance of each node if the chassis
