32-Port 1 Gbps / 2 Gbps Fibre Channel Switching Module
The 32-port 1 Gbps / 2 Gbps Fibre Channel switching module can be used to
allocate bandwidth optimally, and delivers the industry’s highest line-card port
density. The module is organized into eight four-port groups. Only the first port
in each four-port group can be an ISL. If the first port is an ISL, the other three
ports in the group are disabled. The four ports within a port group share a single
internal channel resulting in a subscription ratio of approximately 3.2:1. The
32-port 1 Gbps / 2 Gbps switching module provides more ports at a lower price
per port. Figure 1-6 shows a 32-port switching module.
Tip For a full 2 Gbps bandwidth between two hosts, connect one host to the first port
group and the second host to the second port group.
