2. System Control
This chapter describes the general interaction and functions of the overall SGI UV 2000 system
control. System control parameters depend somewhat on the overall size and complexity of the
SGI UV 2000 but will generally include the following three areas:
• The system management node (SMN) which runs the SGI Management Center software
• The chassis management controllers (CMC) boards - one per IRU
• The individual blade-based board management controllers (BMC) - report to the CMCs
Note: While it is possible to operate and administer a very basic (single-rack) SGI UV 2000
system without using an SMN and SGI Management Center, this is an exception rather than rule.
Levels of System Control
The system control network configuration of your server will depend on the size of the system and
control options selected. Typically, an Ethernet LAN connection to the system controller network
is used. This Ethernet connection is made from a remote PC/workstation connected to the system
management node (SMN). The SMN is a separate stand-alone server installed in the SGI UV 2000
rack. The SMN acts as a gateway and buffer between the UV system control network and any
other public or private local area networks.
Important: The SGI UV system control network is a private, closed network. It should not be
reconfigured in any way to change it from the standard SGI UV factory installation. It should not
be directly connected to any other network. The UV system control network is not designed for
and does not accommodate additional network traffic, routing, address naming (other than its own
schema), or DCHP controls (other than its own configuration). The UV system control network
also is not security hardened, nor is it tolerant of heavy network traffic, and is vulnerable to Denial
of Service attacks.
