    Using the C-Series IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Module (14/2), and MDS 9216i switch in an iSCSI environment iSCSI protocol overview iSCSI is a SCSI transport protocol for mapping of block-oriented storage data over TCP/IP networks through iSCSI protocol data units (PDUs). The iSCSI protocol enables universal access to storage devices and storage area networks (SANs) over standard Ethernet-based TCP/IP networks.

    You can use either Fabric Manager or the switch CLI to create and modify SAN zones. As a best practice of SAN management, HP recommends that you create separate iSCSI zones that contain the iSCSI WWPNs and the storage WWPNs it will access. Refer to the Cisco configuration documentation to create, modify, or activate SAN zones.
