HP 3PAR StoreServ 10000 Storage Physical Planning Manual

The number of ports available for the host connection will vary based on the configuration.
Depending on the number of controller nodes in the system, the type of Fibre Channel adapters
installed, and the method of drive chassis connection being used, an HP 3PAR StoreServ 10000
Storage can support a maximum of 2-48 drive chassis. Controller nodes can hold a maximum of
nine PCI adapters.
Fibre Channel adapters are used to connect to the customer FC switch and/or hosts and connect
controller nodes to drive chassis within the system. They can also be used for Remote Copy
operations.
Required Cables
The quantities and lengths of the cables required for storage system installation vary according to
the specific storage system and network configuration. Fibre Channel cables are used externally
to connect the controller node to the customer switch or host (in the case of a directly connected
host). Fibre Channel cables are used internally to connect the controller node to the drive chassis
(inter-cabinet or cabinet to cabinet).
The Fibre Channel cables provided by HP have a custom strain relief feature to help maintain the
proper bend radius of the cables for drive chassis. For this reason, HP requires that you use only
Fibre Channel cables provided by HP for node-to-drive-chassis connections. HP does not provide
any networking cables or equipment such as Ethernet and modem cables. The table identifies the
types of cables commonly required for storage system installation.

One Ethernet cable for the SP, a minimum of two for two nodes in the system, and one more cable that is available for
node upgrades or node repairs on a system capable of having more than two nodes.
NOTE: For Ethernet and Fibre Channel cables that connect the storage system to the network
and hosts, reserve approximately 7 feet (2 meters) of each cable for internal routing within the
storage server cabinet.
External Cable Connections
Table 11 (page 68) includes specific guidelines for connecting the controller nodes to the network
and to host computers. Refer to “Supported Network Topologies” (page 63) for descriptions of the
supported network topologies.
