Vibration Killing Enterprise Disk Performance?

Posted by timothy on from the aftershocks-even-worse dept.

An anonymous reader writes "Is vibration killing disk performance? ZDnet reports on research that a carbon fiber anti-vibration rack increased random read performance by 56% to 246% and random write [performance] by 34% to 88%. Vibration is a known disk problem, but this is one of the few attempts to quantify its impact — which looks to be much greater than suspected."

    Geeks shouldn't have a vibration problem because their bed is only used for sleeping.

    If you want to have a laugh, check out Bryan Cantrill (Mr. DTrace) and Sun engineer Brendan Gregg shouting at disks and checking out latency heat graphs on YouTube:

    Not to mention all the puns you can make about racks.

    Get off my Rack?

    In Soviet Russia, rack vibrates you?

    All your rack.....?

    A perfect example of why this type of joke flies right over the average /.er's head.
