HP Insight Control Software for Linux - Manual (Page 28)

•
Cap Headroom (Watts) : The spare cap capacity that is identified from the difference of peak power
consumption and power cap values. This helps to identify the power delivery devices with power caps
that can accommodate another system within the already set power cap.
•
Power Summary : The power summary meter provides a visual representation of the utilization of the
power/thermal infrastructure and power details for a power delivery device. For detailed information
on power summary meter, see
Power Summary meter .
Understanding/Using the Physical Location
Insight Control power management can summarize the power/cooling consumption based upon the location
of the systems. Apart from the Systems Insight Manager system objects such as servers, enclosures, switches,
and so on, there are two additional levels:
•
Rack containing systems : For purposes of summarizing power, large free-standing servers are also
considered racks.
•
Data center containing racks : A data center is an arbitrary rectangular grid that allows you to specify
the placement of racks. You may create data centers to describe a lab floor or a portion of a computer
room – that provides a useful grouping for your requirement.
While configuration of the physical location hierarchy is optional, it enables power management to summarize
power/cooling requirements based upon physical groupings. For more information on defining data centers
and racks, see
Defining a data center and Defining a rack .
Rack content is displayed in the Power/Thermal tab for the Systems Insight Manager rack object. It provides
the highest observed system inlet temperatures in the last 24 hours of data collected for each system collected
via the coloring of the system/enclosure box in the rack. Similarly, when viewing the Power/Thermal tab
for a data center, the highest temperature of any system in the rack over the last 24 hours is displayed via
coloring of the rack. Clicking on the rack name will provide the rack visualization to show which systems
are the source of the high temperature.
Understanding the Define Rack page
Understanding the Define Rack page
The various fields and components of the define rack page are described as follows:
•
Rack Name : The Systems Insight Manager display name for the rack.
•
Height (U slot) : The height of rack. The different types of HP racks are 14U, 22U, 36U, 42U, 47U,
and 50U.
