Disable Unicast Storm Control on each switch that processes iSCSI traffic.
Enable Jumbo Frames on each switch and NIC that processes iSCSI
traffic.
Use the proper iSCSI optimization settings for your iSCSI storage

before the switch port enters the forwarding mode, introducing
undesirable network latency.
