7 Cabling the Storage System
For more information about cabling drive enclosures (SAS) before you continue to cable the system,
visit www.hp.com/go/3par. Scroll to Support, and click HP 3PAR StoreServ 7000 Support and
then Manuals. Then scroll to Setup and install general and select the specific HP 3PAR StoreServ
7000 Storage Cabling Configuration Guide.
Cabling Controller Nodes
Nodes are numbered 0 to 3 from bottom to top. Connections between Nodes 0 and 1 and Nodes
2 and 3 use four large interconnect cables.
These cables are directional and must be installed correctly for the storage system to function
properly. When inserting the cables, you should hear a click to confirm the cable is correctly
installed. If you have to force the connector, the connector is upside down and needs to be inverted.
The direction of the cable connection is indicated by labels on either end of the cable.
In Figure 33 (page 50), see label A for interconnecting node 0 or 1. See label C for interconnecting
node 2 or 3.

Host/Ethernet Cables
WARNING! Each controller node supports one Ethernet connection to a switch or hub. Separate
connections from the Ethernet switch or hub to at least two controller nodes are required to support
redundancy. With redundancy, one IP address is shared between the two connections, and only
one network connection is active at a time. If the active network connection fails, the IP address is
automatically moved to the surviving network connection.
WARNING! At a minimum, the storage system requires one Fibre Channel (or iSCSI) connection
from a host computer to a controller node. HP recommends separate connections from each host
computer to each of the controller nodes in the storage system, with connections distributed evenly
across all nodes.
