A shared topology requires:
• A static IP address and system name for the storage system.
• Two Ethernet connections from a switch or hub to the storage system controller nodes.
• A static IP address for the SP.
• One Ethernet connection from a switch or hub to the SP.
• At least one management station on the network segment.
Private Network
With a private network topology, the storage system and the Service Processor (SP) sit on the same
private network segment on the customer local area network. All management workstations used
to administer the system must also sit on the same private network segment (Figure 21 (page 42)).
Figure 21 Storage System and Service Processor on a Private Segment (Private Topology)
A private topology requires:
• A static IP address for the storage system.
• Two Ethernet connections from the storage system to a private network segment.
• One Ethernet connection from the SP to the private network segment.
• At least one management station on the private network segment.
NOTE: It is strongly recommended that the private network segment also have a management
station to communicate with the SP.
TCP/IP Port Assignments
