iSCSI Optimization Overview
iSCSI is a TCP/IP-based protocol for establishing and managing connections between IP-based storage
devices and initiators in a storage area network (SAN).
iSCSI optimization enables the network switch to auto-detect Dell's iSCSI storage arrays and triggers a self-
configuration of several key network configurations that enables optimization of the network for better
storage traffic throughput.
iSCSI optimization also provides a means of monitoring iSCSI sessions and applying quality of service (QoS)
policies on iSCSI traffic. When enabled, iSCSI optimization allows a switch to monitor (snoop) the
establishment and termination of iSCSI connections. The switch uses the snooped information to detect iSCSI
sessions and connections established through the switch.
iSCSI optimization allows you to reduce deployment time and management complexity in data centers. In a
data center network, Dell EqualLogic and Compellent iSCSI storage arrays are connected to a converged
