4. Connect the DSN-4000 Array
You can connect up to four additional DSN-4000 arrays with 16 drive bays each to increase the physical
storage capacity of your DSN-4100 or 4200 storage system, up to a maximum of 80 drives.
To connect the first DSN-4000 expansion array to the DSN-4100 or 4200 primary array, use the following
procedure and refer to the next figure.
A.
Facing the rear of the primary array, connect one end of the expansion chassis cable that was supplied
with the DSN-4000 array to the expansion connector labeled SAS EXP and ensure that it snaps fully
into place.
B.
To attach additional expansion arrays, use the expansion cable that was supplied with the DSN-4000
array between the SAS OUT connector (diamond icon) on one expansion array and the SAS IN
connector (circle icon) on the next expansion array.
The hard disk drives will be numbered sequentially starting with zero in the DSN-4100 or 4200 primary
array, and then continuing as you add any combination of DSN-4000 expansion arrays.
Note:
Only connect DSN-4000 expansion arrays to the DSN-4100 or 4200 storage system. No other
commercially-available SAS expansion arrays are supported, and any drives in those other expansion
arrays will not be found.
