HP 3PAR StoreServ 10000 Storage Physical Planning Manual

5 Network, Cabling and Connectivity
This chapter provides information on determining the best network configuration for the HP 3PAR
Storage systems being installed at your site including the necessary connections and cable routing
options.
NOTE: The information that follows assumes an established network and discusses how to connect
a storage system to that network.
Planning Network Access
External Ethernet, Fibre Channel (FC), iSCSI, FCoE and Remote Copy cable connections are
completed at the time of installation.
These external connections are necessary to:
• Connect the storage system to the network, enabling storage system management through the
3PAR OS Management Console and CLI.
• Allow communication with the Storage System from the Service Processor when in use.
• Enable HP Customer Services personnel to monitor and service the storage system via the
Service Processor. Refer to the Secure Service Architecture white paper for additional
information.
NOTE: All networking equipment, including all necessary switches, hubs, and cables, are to be
provided by the customer unless otherwise indicated.
Supported Network Topologies
Several different network topologies can be used to connect the storage system to the local area
network, depending on operating site policies and requirements. Currently, the major supported
topologies are shared and private. However, other possible network configurations might be
available. To learn more, ask your sales and support representative.
NOTE: To provide redundancy and to permit online software upgrades, both controller nodes
in a single horizontal node pair (for example, nodes 0 and 1, nodes 2 and 3, and so on) must
maintain connections to the internal customer network.
Shared Network
With a shared network topology, the storage system and Service Processor (SP) share the internal
customer network.
