  • Patent number: 7633748
    Abstract: A multiple drive array carrier apparatus and associated method is provided with a unitary two-row partition. The unitary two-row partition has a longitudinal end member. A plurality of first support members extend from the end member and support, in turn, a first set of coplanar engagement members. The first engagement members each define apertures configured for passing first fasteners therethrough to affix a first plurality of data storage devices to the first engagement members, defining a first row of data storage devices. A plurality of second support members also extend from the end member and define a second set of coplanar engagement members. Each of the second support members likewise define apertures configured for passing second fasteners therethrough in the same direction as the first fasteners to affix a second plurality of data storage devices to the second support members, defining a second row of data storage devices adjacent to and parallel with the first row.

  • Patent number: 7423883
    Abstract: A multiple disc array apparatus and associated method are provided having substantially identical first and second partitions that are removably connectable together. Each partition supports a plurality of data storage devices arranged in noncoplanar first and second arrays. Each partition further defines clearance apertures for passing fasteners therethrough for fixing each data storage device to the respective partition.

  • Patent number: 7178307
    Abstract: A composite corrugated panel is provided comprising a first corrugated panel defining a first corrugation height joined to a second corrugated panel defining a second corrugation height, the joined panels defining a cross sectional thickness that is preferably less than a sum of the first and second corrugation heights. A method is provided for producing a composite corrugated panel, comprising: providing a first panel comprising a first corrugation and a first opening; providing a second panel comprising a second corrugation and a second opening; stacking the panels by disposing the first corrugation in the second opening and the second corrugation in the first opening.

  • Patent number: 7177145
    Abstract: A carrier for supporting a circuit board and one or more data storage devices in a multiple disc array assembly. The carrier includes a partition with channel surfaces defining a tubular closed passage. The channel surfaces are adapted for circumscribing a cross section of the data storage device in a supporting mating relationship. The carrier further includes means for urging a data storage device in the passage in pressing engagement against the circuit board. Furthermore, a method for supporting a plurality of data storage devices in the multiple disc array. The method includes providing a carrier from a plurality of different carriers differentiated by a characteristic array of tubular closed channels for supportingly engaging data storage devices; inserting one or more data storage devices in a respective number of channels defining the multiple disc array; and inserting the carrier in a shelf.

  • Patent number: 7133291
    Abstract: An array storage system and associated method are provided comprising a multiple disc array. The multiple disc array comprises a partition defining attachment points for fixing each of a plurality of data storage devices to the partition arranged in a first and a second array, wherein a data storage device in the first array operably spins oppositely with respect to a data storage device in the second array. Two identical partitions, each supporting arrays of data storage devices, can be joined together to increase the storage capacity of the multiple disc array.

  • Patent number: 5926366
    Abstract: A connection structure between a disk drive housing and a rack to eliminate a source of vibration, and hence improve the performance of the disk drive. An interference-fit tab and slot vibration reduction structure is described, where the tab is formed on the housing and the slot is formed on the shelf. The tab and slot vibration reduction structure includes a disk drive having an outer housing, the housing having a bottom surface. A tab extends from the bottom of the housing. A shelf is provided on the rack system for receiving one or a plurality of disk drive housings, and one slot is formed in a front edge of the shelf for each drive housing. When the disk drive housing is positioned on the shelf with the tab positioned in the slot to create an interference fit, the housing is rigidly attached to the shelf.
