Cable Routing Options
For 10 Gigabit Ethernet (10GbE), iSCSI, and Fibre Channel cables that connect the storage system
to the customer network or hosts, approximately 7 feet (2 meters) of each cable must be reserved
for internal routing within the storage system rack.
Network Access
External Ethernet, iSCSI, FCoE, or Fibre Channel cable connections are completed at the time of
installation. These external connections are necessary to do the following:
Establish connections from the controller nodes to the host computer or computers
Connect the storage system to the network, enabling storage system management through the
HP 3PAR Management Console and HP 3PAR Command Line Interface (CLI)
Allow communication to the storage system from the SP
Supported Network Topologies
Several different network topologies can connect the storage system to the local area network,
depending on operating site policies and requirements. Currently, the two supported topologies
are shared and private.
