138 IBM Flex System p260 and p460 Planning and Implementation Guide
5.6 Power planning
When planning the power consumption for your Power Systems compute node,
you must consider the server estimated power consumptions highs and lows
based on the power supply features installed in the chassis and tools, such as
Active Energy Manager. You can use these features to manage, measure, and
monitor your energy consumption.
5.6.1 Power Systems compute node power supply features
The peak power consumption is 632 W for the IBM Flex System p260 Compute
Node and 1264 W for the IBM Flex System p460 Compute Node. Power is
provided by the chassis power supply modules. The maximum measured value
is the worst-case power consumption expected from a fully populated server
under an intensive workload. It also takes into account component tolerance and
non-ideal operating conditions. Power consumption and heat load vary greatly by
server configuration and use.
Use the IBM Systems Energy Estimator to obtain a heat output estimate based
on a specific configuration. The Estimator is available at the following website:

5.6.2 Power Systems compute node PDU and UPS planning
Planning considerations for your IBM Flex System configuration depend on your
geographical location. Your need for power distribution units (PDUs) and
uninterruptible power supply (UPS) units varies based on the electrical power
that feeds your data center (AC or DC, 220 V or 110 V, and so on). These
specifications define the PDUs, UPS units, cables, and support you need.
For information about planning your PDU and UPS configurations, see the IBM
Flex System Power Guide, available at the following address:

The chassis power system is designed for efficiency using data center power,
and consists of 3-phase, 60A Delta 200 VAC (North America) or 3-phase 32A
wye 380-415 VAC (international). The Chassis may also be fed from single
phase 200-240VAC supplies, if required.
