Power Estimation Tool - IBM z13s Technical Manual

Through a Simple Network Management Protocol (SNMP) application programming interface
(API), energy information is available to, for example, Active Energy Manager, which is a
plug-in of IBM Systems Director. See 10.4.4, "IBM Systems Director Active Energy Manager"
on page 383 for more information.
When z Unified Resource Manager features are installed (see 11.6.1, "Unified Resource
Manager" on page 428), several monitoring and control functions can be used to perform
Energy Management. For more details, see 10.4.5, "Unified Resource Manager: Energy
management" on page 384.
A few aids are available to plan and monitor the power consumption and heat dissipation of
z13s servers. This section summarizes the tools that are available to plan and monitor the
energy consumption of z13s servers:

10.4.1 Power estimation tool
The power estimation tool for z Systems servers is available through the IBM Resource Link
website:
http://www.ibm.com/servers/resourcelink
The tool provides an estimate of the anticipated power consumption of a machine model,
given its configuration. You enter the machine model, memory size, number of I/O drawers,
and quantity of each type of I/O feature card. The tool outputs an estimate of the power
requirements for that configuration.
If you have a registered machine in Resource Link, you can access the power estimation tool
on the machine information page of that particular machine. In the Tools section of Resource
Link, you also can enter the power estimator and enter any system configuration for which
you want to calculate power requirements. This tool helps with power and cooling planning for
installed and planned z Systems servers.
10.4.2 Query maximum potential power
The maximum potential power that is used by the system is less than the
depicted in a typical power usage report that is shown in Figure 10-6 on page 382. The Query
maximum potential power function shows what
heat dissipation can be so that you are able to allocate the correct power and cooling
resources.
The output values of this function for
load
are displayed on the Energy Management tab of the central processor complex (CPC)
