Patent number: 8489555Abstract: 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.Type: GrantFiled: June 2, 2011Date of Patent: July 16, 2013Assignee: Teradata US, Inc.Inventors: John Mark Morris, Criselda Carrillo, P.

Patent number: 8375193Abstract: The frequency with which data is accessed within the system may be periodically monitored and a corresponding access frequency quantifier assigned to the data is updated accordingly. The data access frequency quantifier may be associated with a storage device zone speed quality rating. The association between data access frequency quantifiers and the storage device zone speed quality ratings may be made in a hierarchical association such that quantifiable differentials may be ascertained between a particular access frequency quantifier and a storage device zone speed quality rating. In this manner, when no storage zone having a speed quality rating that is associated with data having a particular access frequency quantifier is available for storage of the data, a storage zone having a speed quality rating more proximate the speed quality rating associated with the access frequency quantifier may be identified for migration.Type: GrantFiled: May 27, 2009Date of Patent: February 12, 2013Assignee: Teradata US, Inc.Inventors: Criselda Carrillo, Paul Rubio, Paul Andersen, Donn Holtzman

Patent number: 8041802Abstract: The subject matter herein relates to database management systems and, more particularly, to decoupled logical and physical data storage within a database management system. Various embodiments provide systems, methods, and software that separate physical storage of data from logical storage of data. These embodiments include a mapping of logical storage to physical storage to allow data to be moved within the physical storage to increase database responsiveness.Type: GrantFiled: November 30, 2009Date of Patent: October 18, 2011Assignee: Teradata US, Inc.Inventors: Peter Frazier, Paul Andersen, Gary Boggs, Criselda Carrillo, Donn Holtzman, John Mark Morris, P.

Publication number: 20100306493Abstract: A system, method, and computer-readable medium that facilitate optimized data storage and migration are provided. Storage device zones are tested and assigned respective speed quality ratings. The frequency with which data is accessed within the system may be periodically monitored and a corresponding access frequency quantifier assigned to the data is updated accordingly. The data access frequency quantifier may be associated with a storage device zone speed quality rating. The association between data access frequency quantifiers and the storage device zone speed quality ratings may be made in a hierarchical association such that quantifiable differentials may be ascertained between a particular access frequency quantifier and a storage device zone speed quality rating.Type: ApplicationFiled: May 27, 2009Publication date: December 2, 2010Inventors: Criselda Carrillo, Paul Rubio, Paul Andersen, Donn Holtzman

Patent number: 7822930Abstract: A system calculates the optimal allocation of two or more resources provided by a resource provider to a task within a computer system from a plurality of possible allocations. In doing so, the system calculates the total volume of an N-dimensional cube, where N is the number of resources provided by the resource provider, representing the respective amounts of resources available to be allocated. The system also calculates the average volume of the N?1 dimensional shapes forming the sides of the N-dimensional cube. The system then calculates, at least partly from the ratio of the total volume to the average volume, the balance resulting from the allocation of resources represented by the N-dimensional cube. The system then calculates the imbalance resulting from the allocation of resources at least partly from the balance and determines the smallest imbalance as the optimal allocation of resources.Type: GrantFiled: July 13, 2009Date of Patent: October 26, 2010Assignee: Teradata US, Inc.Inventors: Peter Frazier, Paul Andersen, Gary Boggs, Criselda Carrillo, Donn Holtzman, John Mark Morris, P.

Publication number: 20070067669Abstract: A technique for use in identifying a failing storage device from a plurality of such storage devices involves the use of an inconsistency map. This inconsistency map is maintained by selecting one or more protected objects and identifying the storage devices on which the protected objects are stored. Copies of the protected objects on the identified storage devices are compared. On detecting a mismatch between copies of one of the protected objects, details are stored in an inconsistency map of the mismatched protected object and details of the storage devices on which the mismatched protected object is stored.Type: ApplicationFiled: September 8, 2006Publication date: March 22, 2007Inventors: John Morris, Paul Andersen, Gary Boggs, Criselda Carrillo, John Catozzi, Peter Frazier
