ProSafe M5300 Switch iSCSI The Internet Small Computer System Interface (iSCSI) feature helps network administrators track iSCSI traffic between iSCSI initiators and target systems. This is accomplished by monitoring, or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI sessions and connections. Data from these exchanges may optionally be used to create classification rules to assign the traffic between the stations to a configured traffic class. This affects how the packets in the flow are queued and scheduled for egress on the destination port. In networks containing iSCSI initiators and targets, iSCSI helps to monitor iSCSI sessions or give iSCSI traffic preferential QoS treatment. Dynamically-generated classifier rules are used to direct the iSCSI data traffic to queues that can be given the desired preference characteristics over other data traveling through the switch. This may help to avoid session interruptions during times of congestion that would otherwise cause iSCSI packets to be dropped. However, in systems where a large proportion of traffic is iSCSI, it may also interfere with other network control-plane traffic, such as ARP or LACP. The preferential treatment of iSCSI traffic needs to be balanced against the needs of other critical data in the network.
