** On the Initiator NICs, it's recommended to disable all other protocols and services except for protocols for the iSCSI Service (mainly IPv4). This will reduce interference from the other protocols, and optimize the NIC for performance for accessing iSCSI Storage. | ** On the Initiator NICs, it's recommended to disable all other protocols and services except for protocols for the iSCSI Service (mainly IPv4).
