In this blog we will learn how to change the Round Robin Path Selection Policy (VMW_PSP_RR) on FC and iSCSI LUNs in a VMware environment to better balance the I/O load across all active storage paths and make the setting persistent. Modifying the IOPS limitation to 1 will improve performance where an active storage path …
