1: SGI Altix ICE 8000 Series System Overview
The image that gets loaded onto the Scali Manage Altix ICE compute nodes does get
cached on the leader node. The image comes from the admin node.
Actions for the CMC and compute blades are sent to the appropriate rack leader
controller, which communicates to the appropriate CMC and compute blades. The
compute nodes do not communicate directly to the CMC or admin nodes, or leader
nodes outside their rack.
Generally, the CMC controller is not meant to be accessed directly by system
administrators, however, in some situations you may need to access it to change a
configuration using the LCD control panel. For example, if you added a NAS cube to
your system you need to reconfigure the CMC.
Note:
The LCD control panel is not operational for the first release.
Individual Rack Unit
The individual rack unit (IRU) is one of the basic building blocks of the SGI Altix ICE
8000 series system as shown in Figure 1-1 on page 2. It is described in detail in "Basic
System Building Blocks" on page 1.
Login Service Node
The login service node allows users to login into the system to create, compile, and
run applications. The login node is usually combined with batch and gateway service
nodes for most configurations. The login service node is connected to the Altix ICE
system via the InfiniBand fabric and GigE to the public customer network as shown
in Figure 1-4 on page 14. Additional login service nodes can be added as the total
number of user logins grow.
Batch Service Node
The batch service node provides a batch scheduling service, such as PBS Professional
(not supported on Scali Manage on SGI Altix ICE systems for the first release. You
need to install it separately. It is supported on the SGI Altix ICE software stack). It is
commonly combined with login and gateway service nodes for most configurations.
It is connected to the Altix ICE system via the InfiniBand fabric and GigE to the
public customer network. This node may be separated from gateway and/or login
nodes to scale for large configurations or to run multiple batch schedules.
