If these ping commands fail, check routing settings again. If everything is as it should be try to ping the SP Switch Router Adapter cards to find the failing part:

ping 192.168.13.4 (on nodes in partition 1) ping 192.168.13.129 (on nodes in partition 2)

If any further errors occur, check cabling, the configuration of SP Switch Router media cards (See Section 3.7, “Step-by-Step Media Card Configuration” on page 86) and also the network adapters in the nodes.

Performance:

We did no performance measurement for this scenario. This setup is rather similar to the one described in Section 6.1, “RS/6000 SP Switch - RS/6000 SP Switch Connection” on page 203. There is no good reason why these scenarios should achieve a different data transfer rate. So we expect a data transfer rate of about 80 MB/s between the partitions, as before.
