The ProFibre Storage Array
The ProFibre Storage Array comprises a controller unit and up to seven expansion
units.
Each unit in a ProFibre Storage Array is 3 EIA units high and is suitable for
mounting in an industry standard (EIA) 19-inch rack.
Figure 1. Rack-Mounted Units.
The top diagram shows the front of either a controller unit or an expansion unit; the center
diagram shows the back of a controller unit; the bottom diagram shows the back of an
expansion unit.
At the front of a controller unit or expansion unit are ten device slots 1 . Each slot
must contain either an FC-AL disk drive module, or a dummy module. (A dummy
module is required to maintain airflow for proper cooling of the enclosure.) Each
disk drive module connects to a backplane that is mounted vertically across the
unit. At least one disk drive module must be present in every controller or
expansion unit.
