IBM DS3200 Storage Subsystem manual Cabling the storage subsystem, SAS controller connectors

Chapter 3. Cabling the storage subsystem

After the storage subsystem is installed in its permanent location, you must cable it to hosts, drives, and other external devices, depending on your hardware configuration.

SAS controller connectors

Figure 13 shows controller A, the host ports, and the drive expansion port at the rear of a single-controller DS3200 storage subsystem.

Host port 1, Host port 2, and Host port 3

The DS3200 host ports are each a x4 multilane, 3 Gbps universal mini-SAS port. Connect a SAS cable from your host system SAS host bus adapter to a host port on each controller.

Drive expansion port

The drive expansion port is a x4 multilane SAS port. Connect a SAS cable to this port and to a drive expansion enclosure.
