The control system for the SGI Altix 450 series servers manages power control and sequencing,
provides environmental control and monitoring, initiates system resets, stores identification and
configuration information, and provides console/diagnostic and scan interface.
Each IRU enclosure has a system controller that can communicate with other IRU system
controllers when they are NUMAlinked together under a single system image. Each system
controller constantly shares its information with all controllers in the system. Note that optional
mass storage enclosures do not have a system controller.
Figure 4-1 shows an example system control network using a separate (remote) workstation to
monitor a single-rack Altix 450 system.
