6 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, connections are completed at the time of installation. The customer site will require two static IPs. These external connections are necessary to: • Establish direct connections from the controller nodes to the host computer or computers. • Connect the storage system to the network, enabling storage system management through the InForm 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. 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. Planning Network Access 41
