5.Issue some ping commands to check the connection:
On the SP21 nodes, ping the SP Switch interface of nodes in SP2; on nodes in SP2 ping the SP Switch interface of nodes in SP21.
If these ping commands fail, check routing settings again. If everything is as it should be, try to ping the SP Switch Router HIPPI media card or the SP Switch Router Adapter card to find the failing part:
ping 192.168.14.4 (on SP21 processor nodes)
ping 192.168.13.4 (on SP2 processor nodes)
ping 10.50.1.1 and ping 10.50.1.2 (on both the GRF 400 and the GRF 1600)
If any errors occur, check cabling, the configuration of SP Switch Router media cards (see Section 3.7,
Note: Both HIPPI media cards must be online and cabled, or ping will not succeed.
Performance:
To get a rough overview of the data transfer rates that can be achieved in this scenario, the following test was performed:
1.We used ftp to conduct several file transfers of a 300 MB file from the nodes in SP2 to one chosen node in SP21, and at the same time used ftp to conduct several file transfers of a 300 MB file from the nodes in SP21 to a chosen node in SP2. We sent the files to /dev/null on the receiving node to eliminate any hard disk influence.
Multiple RS/6000 SPs and Multiple GRFs 231
