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 trac), 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 rmware version 6.0 or a later version to display iSCSI queue depth for a
volume.
