Router Boards
The Router board (see Figure 2-9) is a multiported, bidirectional data packet controller
that can transport up to 1600 MB/sec per port (in each direction). Each system module
can have one, two, or no Router boards (depending on the number of Node boards that
are present). The router interfaces with the hubs on Node boards and allows the 64-bit
processors on one Node board to directly access the main memory located on other Node
boards. There are four types of Router boards:
•
Null Router
•
Star Router
•
Rack Router
•
Cray Router
If a module has only one Node board, no Router is required. A Router board is required
only when there are two or more Node boards.
Note:
The Null and Star Router boards are primarily used in SGI 2100 or 2200 deskside
systems. The deskside is equivalent to an individual module in a rackmount system.
