Power Efficiency - Hitachi Compute Blade 2000 User Manual

Power efficiency

This section describes the energy-saving features of the Compute Blade 2000.
Compute Blade 2000 is equipped with the following energy-saving features to reduce power
consumption and initial costs:
 Power monitoring
 Power capping
 Demand Base Switching (DBS)
 Optimum Control on Power Supply Module
 Restriction on maximum power consumption
Power monitoring
Power usage by the server blades and server chassis is displayed in graph format
on the management module's system web console. The server administrator can
easily see how much power is being consumed by the server.
The power usage windows provide a Current Data view and Trend Data view. The
Current Data view shows information about the current power usage of the server
blades and server chassis. The Trend Data view shows historical information about
power usage by the server chassis as a 24-hour graph or in table format.
 Current data view
In the Current Data view, you can view the following power usage data for the server
chassis and server blades.
