Compaq StorageWorks HSG60 ACS Solution V8.6 for SGI IRIX Installation and Configuration Guide

Planning a Subsystem 1–11
Connections
The term “connection” applies to every path between a Fibre Channel adapter in a host
computer and an active host port on a controller.
NOTE: In ACS V8.6 Solution Software the maximum number of supported hosts is 96.
Naming Connections
Compaq highly recommends that you assign names to connections that have meaning in
the context of your particular configuration. One system that works well is to name each
connection after its host, its adapter, its controller, and its controller host port, as follows:
Examples:
A connection from the first adapter in host RED that goes to port 1 of controller A would
be called RED1A1.
A connection from the third adapter in host GREEN that goes to port 2 of controller B
would be called GREEN3B2.
NOTE: Connection names can have a maximum of 9 characters.
Numbers of Connections
The number of connections resulting from cabling one adapter into a switch or hub
depends on failover mode and how many links the configuration has:
■ If a controller pair is in transparent failover mode and the port 1 link is separate from
the port 2 link (that is, ports 1 of both controllers are on one loop or fabric, and port 2
of both controllers are on another), each adapter will have one connection, as shown in
Figure 1–6.
