Queue Depth SAN Headquarters displays the queue depth (average number of outstanding I/O operations at the start of each incoming I/O operation) for each disk drive (raw I/O), volumes (only iSCSI traffic), groups, and pools. A queue depth of zero indicates no I/O activity. High or sustained queue depths might indicate that the group is under a high load. NOTE: A group must be running PS Series firmware version 6.0 or a later version to display iSCSI queue depth for a volume. Monitor Administrative Sessions To monitor administrative statistics: 1.
