Overview of Array Cabling

Sun StorEdge T3 and T3+ arrays have the following connections:

■

One FC-AL interface to the application host

■

One Ethernet interface to the management host (via a LAN) for administration
purposes

■

One serial interface to be used for service tasks by qualified service personnel
only

■

Interconnect ports for configuring arrays into partner groups

Data Path

For the data path (FC-AL) connection, there are three ways that the array can
connect to the host:

■

Direct attached mode to the data host

■

Hub connection, where the FC-AL from the array is connected to a hub on the
same network as the data host
