HP Insight Control Power Management 6.3 User Guide

The type of power cap is determined when selecting:
• A single system, the cap is a static single-system cap.
• Multiple systems, the cap is a static group cap. With a static group cap, each system in the
group is assigned a static linear apportionment of the total group cap.
• An enclosure, the cap is a dynamic power cap. This type of cap dynamically sets and adjusts
caps on the individual systems in the enclosure to meet workload demand while complying
with the total enclosure cap.
NOTE: Dynamic power caps are only set when an enclosure is selected. Selecting all the
blades in an enclosure results in a static group cap.
power delivery
device
A power delivery device is anything that aggregates one or more power consumers such as PDR,
PDU, power strip, and branch circuit.
Power Distribution
Rack (PDR)
A rack module that divides redundant input power to several nearby racks.
Power Distribution
Unit (PDU)
The PDU normally takes a large IEC 309 power plug and distributes power in the rack to
C-20/C-13 plugs, which connect to the power input of servers or enclosures. Each PDU (or more
specifically PDU core) is attached to a single and independent branch circuit. For monitored
PDUs, there may be more than one PDU core that is controlled via a PDU Management Module.
In this type of configuration, the term PDU often is loosely used to refer to the management module
(since it the named entity).
power feed A top-level input of power from the Data center facility into the Power Management-observable
power infrastructure.
rack HP uses a universal rack to hold all supported rack mount hardware. Racks are measured in U
height (each U being a slot). The most common size is 42U, but HP also sells 14U, 22U, 36U,
and 47U racks. See http://www.hp.com/go/rackandpower for options.
rack PDU This represents the input power and multiple outputs to load segments, which can be two per
management module.
Simple Network
Management
Protocol (SNMP)
One management protocol supported by Systems Insight Manager. Traditional management
protocol used extensively by networking systems and most servers. Management Information Base
for Network Management of TCP/IP-based internets (MIB-II) is the standard information available
consistently across all vendors.
Simple Object
Access Protocol
(SOAP)
A lightweight protocol for exchange of information in a decentralized, distributed environment.
single-system
aware (SSA)
A run type that does not support multi-system operations. Tools with this run type are only aware
of the system on which they are running.
system Systems on the network that communicate through TCP/IP. To manage a system, some type of
management protocol (for example, SNMP, or WBEM) must be present on the system. Examples
of systems include servers, workstations, desktops, portables, routers, switches, hubs, and
gateways.
system health
status
This is aggregate status all of the status sources (which can be SNMP, WBEM, and HTTP) that
are supported on a target system, with the most critical status being displayed. The following are
the different system health statuses that can be displayed:
• Critical Systems Insight Manager can no longer communicate with the system. The system
was previously discovered but cannot be pinged. The system might be down, powered off,
or no longer accessible on the network because of network problems.
• Major A major problem exists with this system. It should be addressed immediately. For
systems running an HP Insight Management Agents, some component has failed. The system
might no longer be properly functioning, and data loss can occur.
• Minor A minor problem exists with this system. For systems running Insight Management
Agents, some component has failed but the system is still functioning.
