HP 3PAR StoreServ Concepts Guide: HP 3PAR OS 3.1.3

• Gigabit Ethernet ports
Systems use Gigabit Ethernet ports to enable the Remote Copy over Internet Protocol (RCIP)
solution and to connect the primary and secondary systems in the Remote Copy pair. For
information about Remote Copy, see the HP 3PAR Remote Copy Software User Guide.
• SAS ports
Systems use SAS ports to connect controller nodes to drive enclosures. SAS ports are supported
only on HP 3PAR StoreServ 7000 Storage systems. For information about controller nodes
and drive enclosures, see “HP 3PAR Storage System Hardware” (page 64).
• FCoE Ports
Systems use FCoE ports in order to run FC as a connectivity protocol directly over Ethernet,
in parallel with regular IP traffic (as opposed to using Ethernet exclusively for TCP/IP networks
and FC exclusively for storage area networks (SANs)). CNA support multiple storage
connectivity protocols on a single host bus adapter (HBA); CNA ports can be configured to
be used as an FC or iSCSI port. For information about configuring FCoE ports, see the HP
3PAR Command Line Interface Administrator's Manual.
Port Location Formats
The HP 3PAR CLI and the HP 3PAR Management Console display the controller node FC, iSCSI,
and Gigabit Ethernet port locations in the following format: <Node>:<Slot>:<Port>. For example:
2:4:1.
• Node: Valid node numbers are 0-7 depending on the number of nodes installed in your system.
When viewing a system from the rear of a cabinet:
◦ F-Class nodes are numbered 0–3 from top to bottom.
◦ T-Class nodes are numbered 0–7 from left to right, bottom to top (front of cabinet).
◦ StoreServ 10000 nodes are numbered 0–7 from left to right, bottom to top.
◦ StoreServ 7000 nodes are numbered 0–1 or 0–3 from bottom to top.
• Slot: Valid node slot numbers are 0–9, depending on the class of nodes installed in your
system.
◦ F-Class slots are numbered 0–6 from left to right. Slot 6 is reserved for the RCIP Ethernet
port.
◦ T-Class slots are numbered 0–6 from left to right. Slot 6 is reserved for the RCIP Ethernet
port.
◦ StoreServ 10000 slots are numbered 0–9 from left to right, bottom to top in a node in
the lower chassis. In the upper chassis, slots are numbered 0–9 from left to right, top to
bottom.
◦ HP 3PAR StoreServ 7000 Storage systems have one slot per node. Slot 0 is reserved for
onboard SAS, slot 1 is reserved for onboard FC, and slot 2 is reserved for the HBA.
• Port: Valid node port numbers are 1–4 for all HBAs.
F-Class ports are numbered from top to bottom.◦
◦ T-Class ports are numbered from top to bottom.
