IBM DS3200 Storage Subsystem manual Enclosure ID settings, Working with SAS cables

Enclosure ID settings

The controller automatically sets the enclosure ID number. You can change the setting through the storage management software, if necessary. Both controller enclosure ID numbers are identical under normal operating conditions.

The allowable range of enclosure ID settings is 0 through 99. However, for best results, do not set the enclosure ID to 00 or any number less than 80. The DS3200 enclosure ID is normally set to a value of 85 at the factory.

Working with SAS cables

Each DS3200 RAID controller has up to three x4 multilane SAS host ports and a single x4 multilane SAS port for drive channel connections.

Use a 1M or 3M (1-meter or 3-meter) SAS cable with a mini-SAS 4x multilane SAS connector on each end to connect a controller host port to a host HBA and to connect the drive expansion port to a storage expansion enclosure.

The following illustration shows the 1M and 3M mini-SAS cable.

The 1M and 3M SAS cables have a universal key connector that enables the cable to be used in all mini-SAS ports.
