5 Network, Cabling and Connectivity

This chapter provides information about determining the best network configuration for the HP

3PAR Storage systems being installed at your site, necessary connections and cable routing options.

NOTE: The information that follows assumes an established network and discusses how to

connect an HP 3PAR Storage system to that network.

Planning Network Access

External Ethernet, Fibre Channel (FC), iSCSI, 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

InForm Management Console and CLI.

• Allow communication with the storage system from the Service Processor (SP) when in use.

• Enable HP Customer Service personnel to monitor and service the storage system via the SP.

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 three major

supported topologies are shared , split , 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.

NOTE: The SP is often unused or powered off in the CC mode configuration. In some instances,

the SP is only active for maintenance operations and software updates.

Shared Network

With a shared network topology, the storage system and SP share the internal customer network

(Figure 20 (page 38)).
