4. Connecting Cables

Drive Enclosure Connection

Drive Enclosure Connection
When a drive enclosure is installed, connect the drive enclosure to the controller enclosure with a mini SAS HD
cable between enclosures. When multiple drive enclosures are installed, connect the drive enclosures with mini
SAS HD cables between enclosures.
0.75m mini SAS HD cables between enclosures are provided with 2.5" type drive enclosures and 3.5" type drive
enclosures. 2.5m cables between enclosures are provided with high-density drive enclosures.
The connection type between Controller 0 and the I/O modules for Controller 0 is different from that between
Controller 1 and the I/O modules for Controller 1.
Between Controller 0 and I/O module line 0, connect the source DI (OUT) port and the destination DI (IN) port in
ascending order of the drive enclosure numbers (DE-ID) of the drive enclosure.
Between Controller 1 and I/O module line 1, contrary to the line 0, connect the source DI (OUT) port and the
destination DI (IN) port in descending order of the drive enclosure numbers (DE-ID) of the drive enclosure.
Do not connect anything to the last DI port that is nearest to the edge.
The last ports nearest to the edge are the DI (OUT) port of I/O module 0 in the drive enclosure of the largest DE-
ID and the DI (OUT) port of I/O module 1 in the drive enclosure of the smallest DE-ID.
The connection configurations of cables between enclosures and the last DI port location when two drive
enclosures are installed are shown below.
