6.6 External Cable Connections
Table 6-4 includes specific guidelines for connecting the controller nodes to the network and
to host computers. Refer to Supported Network Topologies on page 6.2 for descriptions of the
supported network topologies.
Table 6-4. External Controller Node Connections
Connection Type Minimum Configuration Recommended
Configuration
Ethernet Connection from the
Ethernet switch or hub to
two controller nodes
See Supported Network
Topologies on page 6.2
Fibre Channel Connection from a host
computer to one
controller node
Separate connections
from host computers to
each node, with
connections distributed
evenly across all nodes
*
* 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 each host server.
Maintenance None Varies according to
system and network
configuration
