D-Rack Administration and RLC Cabling to CMCs Example
The RLC as Fabric Manager
In some SGI ICE X configurations the fabric management function is handled by the rack leader
controller (RLC) node. The RLC is an independent server that is not part of the blade enclosure
pair.
See the “Rack Leader Controller” on page 40 subsection for more detail. The fabric management
software runs on one or two RLC nodes and monitors the function of and any changes in the
InfiniBand fabrics of the system. It is also possible to host the fabric management function on a
dedicated service node, thereby moving the fabric management function from the rack leader node
and hosting it on an additional server(s). A separate fabric management server would supply fabric
status information to the system’s administration server periodically or upon request.
