Power And Thermal Technologies; Power Supply Options; Management And Deployment Technologies; Power And Thermal Management With The Power Management Controller - HP ProLiant s6500 Introduction Manual

• iSCSI boot for Linux ® operating systems lets you boot the server from a SAN so the server needs no
disk drives.

Power and thermal technologies

We developed high-efficiency, right-size power supplies and a common-slot power supply bay for
multiple ProLiant server platforms. Like many other ProLiant G6 and G7 servers, the SL6000 Scalable
System supports these common slot power supplies to increase power efficiency without degrading
server performance.

Power supply options

HP common-slot power supplies are available in four types. This range of available capacities lets you
maintain high operating efficiency during server reconfigurations for both upgrading and
downgrading.
Table 1 shows efficiency data collected by the Electric Power Research Institute (EPRI) during 80 PLUS
measurement tests for HP common-slot power supplies operating from 230 VAC.

Most common load point
Efficiency is the overall goal when choosing power supplies. We recommend using the HP Power
Advisor to identify the best power supply for each SL6000 configuration. Power Advisor can help you
choose from the three available wattage choices the option that meets your needs.

Management and deployment technologies

The SL6000 Scalable System infrastructure has integrated management capabilities based on the
Power Management Controller and LO100i integrated on each server tray. HP Insight Management
Agents provide alerts that let you significantly reduce unplanned downtime. The ProLiant SL6000
Scalable System uses the same SNMP-based Insight Management Agents supported on other ProLiant
servers. You can use HP Systems Insight Manager (SIM) 5.3 and later to manage SL6000 servers.
You can also use any other SNMP-based management tool. The agents are available on the ProLiant
model-specific "Easy Set-up" CDs or from the Internet at

Power and thermal management with the Power Management Controller

The embedded Power Management Controller on each 2U chassis provides advanced power
metering and capping capabilities for the entire chassis. It monitors power consumption throughout
the chassis and throttles processor speed and memory in each node to maintain a preset power
budget. It manages the power capping technology built into the chassis, making extreme density in
the rack possible.
