System Management
This chapter describes the interaction and functions of system controllers in the following
sections:
•
“Levels of System and Chassis Control” on page 17
•
“Chassis Manager Interconnects” on page 18
•
“System Power Status” on page 19
One chassis management controller (CMC) is used in each blade enclosure. The CMC is located
directly below the enclosure’s switch blade(s). 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. The CMC takes direction from the RLC and stays powered-on as long
as there is power applied to the blade enclosure.
Note that the stand-alone service nodes use IPMI to monitor system “health”.
Mass storage enclosures are not managed by the SGI ICE XA system controller network.
Figure 2-1 shows an example remote LAN-connected console communication path to an SGI
(D-rack) containing the administration, RLC and other service nodes for the SGI ICE XA series
system. The E-Cell compute and cooling rack assembly is not shown in this diagram.
