Introduction
The Torridon HS Lite Drive Control Module allows remote switching of the SAS data, power supply
rails and drive presence signal to a SAS or SATA Disk Drive for test automation or fault injection
purposes.
These features allow the user to simulate a number of typical events in a storage system, such as hot
insertion and removal of a disk drive and drive failure.
Each set of Data, Power and Pre-Charge Pins are individually switched, allowing complete control
over the power up sequence of a drive.
The Lite card supports three vendor specific drive presence circuits, please see the Drive Presence
section later in this manual for a description. Quarch modules may be customized to support other
proprietary signals on request.

Control Interfaces
All Torridon Control Modules are designed to be used with a Torridon Array Controller (QTL1079) or
a single Torridon Interface Card (QTL1144).
The control cable is an ultra-thin Flex cable.

Drive Presence Support
The module supports three different proprietary drive presence circuits, all are switched by the
same control signal SPECIAL_1. If the detection circuits are not implemented on the backplane this
circuitry should have no adverse effect on drive operation.
