Quarch Technology Limited, headquarted in Aviemore, Scotland is a world leading supplier of automated test tools for Storage systems. Quarch’s scalable test systems enable manufactures of data storage to get to market faster with a more reliable product. Quarch products can be highly customised allowing the system to achieve a very rapid return on investment in any test environment.


Programmable Power Modules are a combined power supply and recording scope. They are designed mainly to test and characterise storage devices.

Each module has dual power outputs (5v/12v or 3.3v/12v). The output can be set to any level and slewed rapidly to create voltage patterns. A linear regulator allows the output to range from 0v to 20% above the nominal rail value.

Voltage and Current is simultaneously measured on both channels, giving a very accurate power reading. Measurements are taken at 250KHz with a range of averaging levels.

On board memory and a variety of triggering options allow power traces to be easily captured and downloaded for analysis.


These come in several different form factors. Each one for a different removable component in a system:

Drive Modules – For removable drives, such as SAS and PCIe SFF

Cable Pull Modules – For data cables, such as SAS, QSFP and USB

Card Modules – For PCIe slot based devices

SBB Control Modules

All these modules require a controller to provide power and communications. The modules can be used individually, or combined in any number of ways for testing large storage systems.

Physical Layer Switches

These modules are placed between removable cables in the system, in the same way as Cable-Pull modules. As well as breaking the cable connection, we can now swap one device/host for another.

The switches operate at Layer 1. They re-drive the signal, but do not retime or modify data in any way. As such, they are almost identical to having devices directly connected with a cable.

They allow automatic reconfiguration of the system under test. Hosts and devices can be reconnected as required. Most of the switches also support ‘Port Forwarding’, allowing data from one port to be perfectly copied to another (perhaps to an analyser).

Most switches can be directly controlled via USB and LAN. Most also have a Torridon port for connection to a separate controller.
