As you see in the screen shot, the F50’s 9.2 MB/s comes very close to the theoretical maximum throughput of about 10-11 MB/s. So we decided to put some stress on the network, as follows:

On two SP21 nodes, we started ftp put commands to the F50, while the F50 was busy, putting data to other SP21 nodes, and observed an aggregate throughput over the Ethernet adapter of up to 15 MB/s, with more than 35% collision on the Ethernet and the F50 23% busy.

5.1.2 SP Switch - FDDI Connection

This is quite an easy scenario. It is used to connect workstations equipped with an FDDI interface card, FDDI hubs, and similar FDDI network devices to the SP Switch.

Configuration assumptions:

•The SP Switch Router FDDI media card was installed according to Section 4.4, “FDDI Configuration” on page 121, and works properly.

•The SP Switch Router Adapter card was installed according to Section 3.7, “Step-by-Step Media Card Configuration” on page 86, and works properly.

•The SP Switch Router Adapter card and SP processor node Switch adapters are in the same IP subnet.

•ARP should be enabled on the SP Switch network to provide the most flexibility in assigning IP addresses (strongly recommended!).
