After you enable iSCSI, iSCSI optimization automatically detects Dell EqualLogic storage arrays directly attached to switch ports. To support storage arrays where auto-detection is not supported, manually configure iSCSI optimization using the iscsi profilestorage name command. iSCSI optimization enables a switch to auto-detect Dell's iSCSI storage arrays and auto-configure switch ports to improve storage traffic throughput. The switch monitors iSCSI sessions and applies QoS policies on iSCSI traffic. iSCSI optimization operates with or without DCBX over an Ethernet network. • iSCSI uses the current flow-control configuration by default. If you do not configure flow-control, iSCSI auto-configures flow control settings so that receive-only is enabled and transmit-only is disabled. • The switch monitors and tracks active iSCSI sessions, including port information and iSCSI session information. • A user-configured iSCSI class of service (CoS) profile is applied to all iSCSI traffic. Classifier rules are used to direct the iSCSI data traffic to queues with preferential QoS treatment over other data passing through the switch. Preferential treatment helps to avoid session interruptions during times of congestion that would otherwise cause dropped iSCSI packets. Converged data center services 761
