Managing The Chassis - IBM NeXtScale System Planning And Implementation Manual

7.2 Managing the chassis

The IBM NeXtScale n1200 Enclosure includes the Fan and Power Controller
(FPC) that manages with power supply units and fans that are at the rear of the
enclosure. In contrast to the IBM BladeCenter or IBM Flex System enclosures,
the IBM NeXtScale n1200 Enclosure does not contain a fully functional
management module that allows any management operation to be performed on
the installed nodes. The FPC module is kept simple and as with the IBM
iDataPlex system, compute nodes are managed through their IMM interface
rather than a rich management module in the chassis.
The FPC module provides information regarding power usage at chassis or node
level, fan speed, and allows the setting of specific power and cooling policies.
Additionally, the FPC module adds a few management capabilities of the
compute nodes that are installed in the chassis.
The FPC module has the following features:
Power usage information at the chassis, node, power supply units (PSU), and
fan levels.
PSU and fan status information
Can configure wanted redundancy modes for operation (non-redundant, N+1,
N+N, and oversubscription)
Reports fan speed, fan status, and allows acoustic modes to be set
Can define a power cap policy at chassis or node level
For more information about features and functional behavior, see 3.7, "Fan and
Power Controller" on page 47 .
Managing and configuring the FPC module can be done through a basic web
browser interface that is accessed remotely by the Ethernet connection it has or
remotely though the IPMI interface it provides.
The following sections describe how FPC module can be managed and
configured from both interfaces. Although a web browser interface is intended to
manage a single chassis, the IPMI interface can be used to develop wrappers
that enclose IPMI commands to manage multiple chassis in the network.
The following topics are included:
7.2.1, "FPC web browser interface"
7.2.2, "FPC IPMI interface" on page 202
