Sun Microsystems 2500 manual To Connect Data Hosts to a 2530 Array

Before you connect data hosts directly to the array, check that the following prerequisites have been met:

■Interface cables are connected and between the HBAs and the array controllers.

■SAS cables (1-, 3-, or 6-meters) are available to connect the array host ports to the data host HBAs.

Each controller module on a controller tray has three SAS host ports (FIGURE 3-11).

▼To Connect Data Hosts to a 2530 Array

1. Locate the host ports at the back of the controller tray (FIGURE 3-11).

If the host port has a plastic protection plug, remove it.

2. Connect one end of the SAS cable to a host port on a controller module.

Host ports are numbered from left to right: host port 1, host port 2, and host port 3.

3.Connect the other end of each SAS cable to a data host HBA.

4.Affix a label to each end of the cable. See “Host Cable Labeling” on page 59 for information about cable labels.

5.Repeat these steps for each host-to-controller connection.
