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.
The RMC is a separate stand-alone 1U controller installed in the SGI UV 3000 system rack. The
RMC acts as a gateway and buffer between the UV system control network and any other public
or private local area networks or administrative systems used to communicate with and control the
UV 3000. An Ethernet connection directly from the RMC to a local private or public Ethernet
allows the system to be administered directly from a local or remote console system. Figure 2-1
shows a front-view example of the RMC unit.
The system controller network is designed into all IRUs. Controllers within the system report and
share status information via the CMC Ethernet interconnects. This maintains controller
configuration and topology information between all controllers in an SSI. Figure 2-2 on page 32
shows an example system control network using an optional and separate (remote) workstation to
monitor SGI UV 3000 systems. It is also possible to connect an optional PC or (in-rack) console
(see Figure 2-4 on page 36) directly to the RMC.
Note: Mass storage option enclosures are not specifically monitored by the system controller
network. Most optional mass storage enclosures have their own internal microcontrollers for
monitoring and controlling all elements of the disk array. See the user's guide for your mass
storage option for more information on this topic.
