System Management
This chapter describes the interaction and functions of system controllers in the following
sections:
•
“Levels of System and Chassis Control” on page 19
•
“Chassis Manager Interconnects” on page 20
•
“System Power Status” on page 23
One or two chassis management controllers (CMCs) are used in each blade enclosure. A single
CMC is used with single-node blades and two CMCs are needed when the enclosure uses
dual-node blades. The first CMC is located directly below the enclosure’s switch blade(s) and the
other directly above. The chassis manager supports power-up and power-down of the blade
enclosure’s compute node blades and environmental monitoring of all units within the enclosure.
Note that the stand-alone service nodes use IPMI to monitor system “health”.
Mass storage enclosures are not managed by the SGI ICE X system controller network.
Figure 2-1 shows an example remote LAN-connected console used to monitor a single-rack
(D-rack) SGI ICE X series system.
