If these ping commands fail, check routing settings again. If everything is as it should be, try to ping the GRF Ethernet media card or the GRF SP Switch media card to find out which part is failing:

ping 192.168.14.4 (on chosen SP21 processor nodes)

ping 10.20.30.1 (on F50)

If any 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 Section 4.1, “Ethernet 10/100Base-T Configuration” on page 105) and network adapters in the F50 and the SP nodes.

Performance:

To get a rough overview of the data transfer rates that can be achieved in this scenario, we used ftp to conduct several file transfers of a 300 MB file from the F50 to the chosen nodes in SP21. We sent this file to /dev/null on the SP21 nodes to eliminate any hard disk influence on the receiver side:
