Traffic between HBAs and Storage System Ports

connected to ports on the storage system.
If XP Performance Control is enabled, Performance Monitor provides statistics about traffic between
HBAs and storage system ports. The traffic statistics reveals the number of I/O requests that have
been made from hosts and also reveals the size of data transferred between hosts and storage system
ports. For details on how to view traffic statistics about HBAs, see

Statistics can be stored for time periods of 8 hours or up to 15 days, and changes depending on the
collecting interval specified. Statistics that have expired are erased from the storage system. For details
