Please find some information on configuring the switch below...
These configuration recommendations assume that the switches are being used predominantly for iSCSI traffic. If other significant flows are present then the configuration will need to be reviewed specifically.
The steps below assume that stack configuration and/or uplink configuration have been completed appropriately.
The use of link aggregation between switches and arrays with multiple connections should be considered to better protect the environment from loop conditions caused by other equipment.
Flow control and buffer configuration
Active management of traffic flows:
Switch (config)#symmetric-flow-control enable
Optimise buffer allocations on all ports of the switch
Note: all flow control configuration MUST also be enabled on all devices connected. Brocade recommends that customers should verify all negotiable parameters, such as flow control, at initial setup and whenever a network element configuration is changed.
All servers/arrays connected to the iSCSI SAN should have jumbo frame support enabled. This also needs to be enabled on the switch.
iSCSI traffic can generate bursts of heavy traffic that can be mistaken as traffic storms. As such, rate limiting should be off. This is off by default and should not be enabled.
I hope this helps - is there anything else specific that you wanted to know about ?
