HP 3PAR T-Class Installation and Deinstallation Guide

Configuration Planning
In addition to verifying the operating site meets all physical and environmental requirements, the
preinstallation process also includes configuration planning.
• Hardware configuration planning issues such as system component layout and drive magazine
allocation are discussed in this chapter and in the HP 3PAR S-Class/T-Class Storage System
Physical Planning Manual.
• Networking and cabling issues such as storage system and service processor network
topologies, internal system cabling configurations, and cabling of connected host computers
are discussed in this chapter and in the HP 3PAR S-Class/T-Class Storage System Physical
Planning Manual.
• System planning issues such as volume management, SAN implementation, and currently
supported platforms and hardware configurations are discussed in the HP 3PAR Systems
Assurance Document or other systems planning documents
.
Planning Network Access
External Ethernet, Fibre Channel, and optional modem cable connections are completed at the
time of installation.
NOTE: All networking equipment, including all necessary switches, hubs, and cables are to be
provided by the customer unless otherwise indicated.
These external connections are necessary to:
• Establish connections from the controller nodes to the host computer or computers.
• Connect the storage system to the network to enable the storage system management through
the Management Console and CLI.
• Enable access to storage system equipment from a service processor.
• Enable HP Customer Services personnel to locally and remotely monitor and service the storage
system.
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 supported
topologies are shared, split, and private.
Shared
With a shared network topology, the storage system and service processor share the internal
customer network (Figure 1 (page 11)).
