Dot Hill/Seagate Assigned Two Patents

Storage device sled and assembly
Dot Hill Systems Corporation, (part of Seagate CSSG), Longmont, CO, has been assigned a patent (9,558,789) developed by Van Pelt, Kevin Lee, Morris, Charles Powell, and Schroeder, Christopher Ellis, Longmont, CO, for a “storage device sled and assembly method thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An improved storage device sled is provided. The storage device sled includes first and second portions, each of which includes a threaded fastener, a longitudinal member, and a bezel member. The longitudinal members are configured to couple to mounting holes of a storage device. Each of the bezel members is orthogonal to a longitudinal member. One of the bezel members includes a latching clip and cutouts to receive one or more alignment projections. The other bezel member includes a latching clip receiver, configured to receive and capture the latching clip, and the one or more alignment projections. Each of the longitudinal members includes a hole for the threaded fastener, which retains the longitudinal member to a mounting hole on a side of the storage device. The longitudinal members also include a tapered post, which captures a mounting hole on a side of the storage device.“

The patent application was filed on September 30, 2015 (14/871,173).

Efficient cache read ahead
Dot Hill Systems Corporation, Longmont, CO, has been assigned a patent (9,552,297) developed by Traut, Zachary David, Denver, CO, and Barrell, Michael David, Superior, CO, for a “method and apparatus for efficient cache read ahead.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for providing improved sequential read performance in a storage controller is provided. In response to the storage controller receiving a host read request from a host computer, the method includes identifying, by the storage controller, a largest burst length of a plurality of burst lengths in a memory of the storage controller, and determining a maximum number of consecutive times between bursts having a value less than a predetermined value. A burst includes a consecutive group of sequential host read requests from the same host computer. The method also includes multiplying the largest burst length of the plurality of burst lengths by the maximum number of consecutive times between bursts having a value less than the predetermined value to obtain an effective burst length and reading into a storage controller cache memory at least the effective burst length of data from storage devices coupled to the storage controller.“

The patent application was filed on July 29, 2013 (13/952,733).
