Drive card testing at the UNH-IOL

The Interopability Lab at the University of New Hampshire has been investigating the performance of our drive control cards.

When using test equipment in a live system, there is always a worry that faults may be caused by the test equipment rather than being a genuine failure. Our drive control cards sit directly in the chain, between the mid-plane and the drive. In this case there are extra connections and routing on the high-speed data lines.

In order to test the effect of adding a Torridon control card, the IOL staff took a series of eye-diagrams while running live data to the drive. As can be seen below, there is no measurable effect to the signal when our cards are added.
