iSCSI Optimization
Internet small computer system interface (iSCSI) optimization enables quality-of-service (QoS) treatment for iSCSI storage
traffic on an Aggregator.
NOTE: When iSCSI storage devices are detected on the server-ports, storm-control is disabled on those ports. When the
iSCSI devices are off the ports, storm-control is enabled again.
