6.2.1.2 Split Network
With a split network topology, the storage server is on the internal customer network, but the
storage server communicates with the service processor on a dedicated private network
segment (Figure 6-2).
Figure 6-2. Storage Server on the Local Area Network with the
Service Processor on a Private Segment (Split Topology)
A split topology requires:
◆ Two static IP addresses and a system name for the storage server.
One IP address is for the LAN and the other IP address is for the private network
segment. Only one interface per network is active at any one time.
◆ Two Ethernet connections from a switch or hub to the storage server controller nodes.

NOTE: A split network topology with redundancy is only supported on systems
with four controller nodes such as the F400 Storage Server.
1 For an InServ with 2 nodes, it is only possible to create one Ethernet connection from a switch or hub to a
storage server controller node and one Ethernet connection from the private network segment to a controller
node. This configuration does not support redundancy.
