Figure 26. Partitioning
Normally, RS/6000 SP nodes in different partitions cannot communicate with each other through the SP Switch. The GRF plays a unique role here by allowing RS/6000 SP nodes to communicate across partitions, when each partition contains at least one SP Switch router adapter, and these adapters are interconnected by TCP/IP.
The requirements for partitioning are the same as those for coexistence, with the addition of having at least one free SP Switch port per partition, to connect to the SP Switch router adapter.
2.5 Planning for the GRF
Before acquiring any model of the SP Switch Router, ensure that there are SP Switch ports available in the designated partition, and that the switch used in the RS/6000 SP is the
Router Node 63
