Determining port throughput
FA-3D Port 0 is not a member of the active zone set. This means that it is an unused
port on the Symmetrix array and has no throughput. The Performance View displays
port throughput and can be used to determine if a port is unused.
Figure 111 shows an example of how a port with no throughput appears in the
Performance View with the Port Throughput and Port I/O both displaying a value of
“0”.

In situations where throughput might be an issue, the administrator can use Ionix
ControlCenter Performance Manager (which is not installed in this scenario, but is
demonstrated in “Identifying a storage array performance problem” on page 64) to
check port throughput.
