When configuring the iSCSI SAN from the host to the XtremIO cluster, it is recommended to disable flow control features on the server, switches, and array ports.Flow control can cause a performance impact by serializing the flow for iSCSI ports, which is not desirable in high-performance storage solutions like XtremIO1. Disabling flow control ensures that the storage array operates without the limitations that flow control can impose, thus maintaining optimal performance.

Dell EMC Switch Configuration Guide for iSCSI and Software-Defined Storage provides guidelines for the design and configuration of storage networks for iSCSI SAN, which includes recommendations on flow control settings2.

Community discussions on Dell Technologies website where it is mentioned that the latest best practices advise against enabling flow control for iSCSI with XtremIO, as it limits performance1.
