Abstract
A carrier and associated methodology for removably supporting a plurality of data storage devices as a multiple disc array in a distributed storage system. The carrier defines attachment features for fixing each of the data storage devices to the carrier preventing movement of the data storage devices in relation to the carrier in response to a vibration stimulus. This reduction in vibration stimulus allows the individual data storage devices in the multiple disc array to increase the number of track per storage area. This benefit can be used to increase capacity, increase performance and increase reliability of the multiple disc array.
Claims20
An apparatus comprising a carrier for removably supporting a plurality of data storage devices in a multiple disc array, the carrier comprising a first partition rigidly affixed to a second partition, the first partition rigidly attaching a selected portion of said plurality of data storage devices thereto and the second partition rigidly securing the remaining portion of said plurality of data storage devices thereto to increase an effective mass of a selected one of the data storage devices to a total mass of the first and second partitions and the plurality of data storage devices for rotational vibration interference (RVI) suppression.
A method comprising:
- providing a carrier comprising first and second partitions;
- rigidly affixing each of a first plurality of data storage devices to the first partition and each of a second plurality of such devices to the second partition;
- and
- rigidly affixing the first partition to the second partition so as to suppress rotational vibration interference (RVI) by increasing an effective mass of each of the individual devices to substantially equal a combined mass of the carrier and the first and second pluralities of devices.
An array storage system comprising:
- a number 2N of data storage devices where N is a plural number;
- and
- means for preventing rotational vibration interference in the data storage devices by increasing an effective mass of each of the individual data storage devices to a total mass greater than a combined mass of the 2N data storage devices.
