Enclosure ID settings
The enclosure ID is a unique two-digit identifier for each enclosure in the storage
subsystem configuration. In a dual controller or ESM configuration, both enclosure
IDs are identical under normal operating conditions. Each EXP3500 storage
expansion enclosure and DS3500 storage subsystem in the storage subsystem
configuration must have a unique storage enclosure ID.
The controller automatically sets the enclosure ID. You can change the setting
through the DS Storage Manager software, if necessary. The range of supported
enclosure ID settings is 0 through 99. The enclosure ID is normally set to a value of
00 at the factory.
The enclosure ID is displayed on the seven-segment numeric display located on the
back of each controller and ESM.
Working with SAS cables
Each DS3500 RAID controller has up to four 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 an 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.
