If you are installing a compute node model without an integrated Ethernet
controller, you must install a network interface adapter before you install the
compute node in the chassis for management network communication. For a list of
supported optional devices for the compute node, see http://www.ibm.com/
systems/info/x86servers/serverproven/compat/us.
The following tables provide an indication of the quantity of nodes that can be
installed in a chassis for specific processor types assuming nodes have all DIMM
slots, PCIe slots, and hard disk drives populated. The tables are based on 900-watt
or 1300-watt power supplies and the indicated power settings. However, when
building a NeXtScale n1200 Enclosure solution, you are required to validate the
power requirements for your configuration using the latest version of the IBM
Power Configurator to ensure that the number of power supplies selected are
adequate for supporting your chassis configuration. Failure to validate the
configuration with the IBM Power Configurator tool could result in system errors,
failure to power on, or microprocessor throttling, and limiting system's ability to
leverage all of the microprocessor performance. The Power Configurator tool can
be found at http://www-03.ibm.com/systems/bladecenter/resources/
powerconfig.html. If there are questions or issues regarding a configuration and
Power Configurator, please send them to power@us.ibm.com.
Note: 1. OVS (Oversubscription) of the power system allows for more efficient use
of the available system power.
