Issue some
On the SP21 nodes,
nodes in SP2
If these
as it should be, try to
Switch Router Adapter card, to find the failing part:
If any errors occur, check cabling, the configuration of the SP Switch
Router media cards (see Section 3.7, "Step-by-Step Media Card
Configuration" on page 86 and Section 4.2, "ATM OC-3c Configuration" on
page 110) and the Switch adapters in the SP nodes.
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
nodes to eliminate any hard disk influence:
We saw up to about 14.5 MB/s with just one side sending data; with all
nodes sending and receiving, we achieved a duplex throughput of no more
than 24 MB/s over the ATM ports.
