* The Activity bar graph is a 6-segment drive activity meter, showing activity of the
SAS interface to the sideplane. For zero activity, no segments are lit, scaling lineary
until all segments are lit when the interface is transferring data at full capacity.

Drives

Drives are provided with dual interfaces and these are connected into sepa-
rate storage domains. Therefore a fault in one controller does not prevent
the other from operating.
All drives are dual ported, so more than one initiator will be communicating
with the device at any point in time. All drives therefore support SCSI reser-
vations. This is a method to allow a controller to "own" access to a given
device, reserving it for its exclusive use.
All drives provide error detection and correction capabilities. These are
reported to the application in line with the SCSI specifications.
