Teradata Assigned Two Patents

Allocating storage space from storage devices within computer
Teradata US, Dayton, Ohio, has been assigned a patent (8,458,428) developed by Peter Ian Frazier, Princeton, NJ, Donn Harold Holtzman, and John Mark Morris, San Diego, CA for a "method of allocating storage space from storage devices within a computer system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method and system for allocating storage space from storage devices within a computer system. The storage devices are grouped into respective homogeneous sets in which identical storage devices are included in the same homogeneous set. In accordance with the method and system, following receipt of an allocation request for storage space one or more stored response values are checked, the response values associated with at least one homogeneous set. The stored value or values represent the average response time of storage devices within the set. The homogenous set with the lowest average response time is selected. One or more stored allocation values are then checked that are associated with at least one storage device within the selected homogeneous set. The stored allocation value or values represent the current allocations of the associated storage device. The storage device is selected with the lowest current allocations and the storage space is allocated in the first available location on the selected device."

The patent application was filed on Jan. 31, 2007 (11/669,355).

Managing storage and retrieval of data objects
Teradata US, Dayton, Ohio, has been assigned a patent (8,489,555) developed by John Mark Morris, San Diego, Criselda Carrillo, and P. Keith Muller, San Diego, for "method of managing storage and retrieval of data objects."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A technique for managing storage of a data object in a storage device involves receiving the data object (A) to store in the storage device, where the data object has an indicator bit pattern (P). Successive compression data transformations are applied to data object A to obtain respective corresponding compressed data objects, and one of these compressed data objects is selected, such that the selected compressed data object (C) has the shortest length with respect to the remaining compressed data objects. Compression information (I) is then associated with the compression data transformation used to generate data object C, and a threshold value T is calculated at least partly from the length of compression information I. If length (C)+T.gtoreq.length (A), then the indicator bit pattern of data object A is reset and the data object A is written to the storage device. If length (C)+T<length (A), then the indicator bit pattern of data object C is set, compression information I is incorporated into data object C, and data object C is written to the storage device."
