iSCSI Optimization

An Aggregator enables internet small computer system interface (iSCSI) optimization with default iSCSI

parameter settings(Default iSCSI Optimization Values) and is auto-provisioned to support:

iSCSI Optimization: Operation

To display information on iSCSI configuration and sessions, use show commands.

iSCSI optimization enables quality-of-service (QoS) treatment for iSCSI traffic.

Supported Modes

Stacking, VLT, Standalone, PMUX, and Full–Switch

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 self-

configuration of several key network configurations that enables optimization of the network for better

storage traffic throughput.

iSCSI optimization provides a means of monitoring iSCSI sessions and applying 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.
