System Information
Model: E880-9119-MHE
Cores: 32 cores of 8-128
Processor: IBM POWER8
Clock Speed: 4350 MHz
Configured Memory: 1024 GB
Energy Estimate
Nominal Mode
The following estimation was made without
enabling any power saver modes. Thus the
cores are running at the published frequency
and the system capacity is as published.
In Active Energy Manager this is described
as "no power savings mode." Using Active
Energy Manager to specify power saver
modes may significantly reduce energy
consumption.
Est. energy at 50% CPU utilization:
Est. energy at full utilization:
1,910 Watts
2,070 Watts
6,519 BTU/hr
7,065 BTU/hr
1,756 Watts
5,994 BTU/hr
Energy Estimate
Static Power Saver Mode
The following estimation was made by
employing "static power saver mode", which
can be enabled using Active Energy Manager,
to reduce the energy consumption of the
system. In this mode the operating frequency
(GHz) of the cores is reduced. This will cause
the system capacity potential to decrease
and the utilization to increase relative to an
equivalent throughput rate in nominal mode.

Note: This is an estimate only. Actual results may vary.
Note: This energy estimate is based on default settings for IBM EnergyScale
technology unless specified otherwise. Using Active Energy Manager to specify Static
or Dynamic Power Saver Modes may significantly reduce energy consumption.
Note: Data used for this energy estimate was collected in an ambient temperature
environment using redundant power supplies with system resources operating near
maximum levels, unless specified otherwise in the table above.
Note: At least one energy estimate above has been adjusted for an expected CPU
utilization. Energy requirements for the processor cores were adjusted based on the
expected CPU utilization.
Note: The calculated energy estimate is an expected, typical value for this system
configuration under normal environmental operating conditions. It should not be used in
planning the electrical supply infrastructure. The maximum power usage for a system,
usually found in site and hardware planning guides, should be used for electrical circuit
design and planning.
Note: The number of memory DIMMs and their placement may impact system
performance.
Note: If the term 'Inactive Cores' is not included in the list of Included Features or
Hardware line items, then an adjustment has not been made to reduce the energy
estimate for Inactive versus Active cores.
