System Control Overview

12
All SGI UV 2000 system individual rack units (IRUs) use an embedded chassis management
controller (CMC). The CMC communicates with both the blade-level board management
controllers (BMCs) and the system management node (SMN), which runs the SGI Management
Center software. In concert with the SGI Management Center software, they are generically
known as the system control network.
The SGI UV 2000 system control network provides control and monitoring functionality for each
compute blade, power supply, and fan assembly in each individual rack unit (IRU) enclosure in
the system. The IRU is a 10U-high enclosure that supplies power, cooling, network fabric
switching and system control for up to eight compute blades. A single chassis management
controller blade is installed at the rear of each IRU.
The SGI Management Center System Administrator's Guide (P/N 007-5642-00x) provides more
detailed information on using the GUI to administer your SGI UV 2000 system.
The SGI Management Center is an application that provides control over multiple IRUs, and
communication to other UV systems. Remote administration requires that the SMN be connected
by an Ethernet connection to a private or public Local Area Network (LAN).
The CMC network in concert with the SMN provides the following functionality:
• Powering the entire system on and off.
• Powering individual IRUs on and off.
• Power on/off individual blades in an IRU.
• Monitoring the environmental state of the system.
• Partitioning the system.
• Enter controller commands to monitor or change particular system functions within a
particular IRU. See the SGI UV CMC Software User Guide (P/N 007-5636-00x) for a
complete list of command line interface (CLI) commands.
• Provides access to the system OS console allowing you to run diagnostics and boot the
system.
