System Administration Server

007-5806-004
Each SGI ICE X system will have one system administration controller, at least one rack leader
controller (RLC) and at least one service node. All ICE X systems require one RLC for every eight
CMCs in the system. Figure 3-4 shows an overview of the SGI ICE X system management and
component network interaction.

Figure 3-4 SGI ICE X System and Network Components Overview
The administration server and the RLCs are integrated stand-alone 1U servers. The service nodes
are integrated stand-alone non-blade 1U or 2U servers. The following subsections further define
the free-standing server unit functions described in the previous list.
There is a minimum of one stand-alone administration controller server and I/O unit per system.
The system administration controller is a non-blade SGI 1U server system (node). Note that a
high-availability administration server configuration is available that doubles the number of
