• Streamlined Web 2.0 interface with JavaScript Object Notation (JSON) technology to create a more dynamic
interface experience. Content updates do not require a web page refresh.
• Streamlined user experience with remote console direct access. It provides immediate access to the iLO Advanced
remote console without having to navigate through the web interface.
• Enhanced standards support with AES encryption for customers with elevated security requirements
• IPMI LAN/DCMI support for performing simple monitoring and control operations
Power management technologies
To accurately monitor and provision server power use, ProLiant G7 server blades include three HP power
management tools, enabled through iLO 3:
• HP power meter
• HP Power Regulator for ProLiant
• HP Dynamic Power Capping and HP Power Capping
Power meter
An HP integrated power meter in ProLiant c-Class server blades analyzes server power use. The BladeSystem OA
can access the power meter through iLO or through external power management software such as HP Insight Power
Manager (IPM). The BladeSystem OA provides instant and time-averaged views of the power consumption of
individual servers or of all servers within the c-Class BladeSystem enclosure. IPM also consolidates power data for
multiple servers to a central location. IT departments can use this information to charge business units or third parties
for the actual energy costs associated with workload processing.
HP Power Regulator for ProLiant servers
HP Power Regulator for ProLiant servers provides firmware-based speed stepping for recent AMD processors. Power
Regulator improves server energy efficiency by giving processors full power when they need it and reducing power
when they don’t. This power management feature allows ProLiant servers with policy-based power management to
control processor power states. IT administrators can configure Power Regulator for HP Static High Performance
mode, HP Static Low Power mode, or HP Dynamic Power Savings mode. The latter automatically adjusts available
power to match processor demand. You can find additional information on the HP Power Regulator in the paper
titled “Power Regulator for ProLiant servers” at

HP Dynamic Power Capping and HP Power Capping
All BladeSystem G7 c-Class server blades with iLO 3 support Dynamic Power Capping and HP Power capping
(basic Power Capping). Both technologies achieve the same general goal of maintaining server power consumption
at or below the cap value set by an administrator. But HP Dynamic Power Capping monitors power consumption
and responds to changes much more rapidly than basic Power Capping.
Dynamic Power Capping can bring a server experiencing a sudden increase in workload back under its power cap
in less than one-half second. This fast response prevents any surge in power demand that could trip a typical data
center circuit breaker. Dynamic Power Capping prevents tripping circuit breakers that have a specified trip time of
3 seconds or longer at 50 degrees C and 150 percent overload.
Dynamic Power Capping can be an effective tool in planning and managing both electrical provisioning and
cooling requirements in the data center. An administrator can electrically provision a PDU or a rack to something
less than the full faceplate power rating of all the servers supported. That’s because Dynamic Power Capping
guards against any unexpected change in power consumption that might trip a circuit breaker.
