FISHWORKS: Screaming in the Data Center

Xiotech’s ISE segregates mounted disk drives back-to-back on a center-plane (as opposed to a backplane).  The drives that are back to each other spin in opposite directions — this counters vibration.  Additonally, the center-plane acts a heatsink.  Reducing drive vibration and heat are two of the integral factors.

Notice also that there is no backplane anywhere inside the 3u enclosure — this means air flows fully through the device which means much more cooling with less energy expended.

Our friends at SUN FISHWORKS have studied this and produced a video to demonstrate how vibration can affect drive performance:
