Patent number: 9052826Abstract: Techniques for selecting physical storage locations for storing data are provided. A technique involves determining usage statistics associated with a logical block in a file system, selecting a physical storage location, of a plurality of physical storage locations, to assign to the logical block based on (a) at least one attribute associated with the first physical storage location, and (b) the usage statistics associated with the logical block, and causing the logical block to be assigned to the first physical storage location.Type: GrantFiled: January 4, 2011Date of Patent: June 9, 2015Assignee: CONDUSIV TECHNOLOGIES CORPORATIONInventors: Gary Quan, Basil Thomas, Craig Jensen

Publication number: 20150039837Abstract: Method for data placement in a tiered caching system and/or tiered storage system includes: determining a first period of time between each access to a first data, in a predetermined time window; averaging the first periods of time between each access to obtain an average first period of time; determining a second period of time between each access to a second data, in said predetermined time window; averaging the second periods of time between each access to obtain an average second period of time; comparing the average first period of time and the average second period of time; placing the first data in a fast-access storage medium, when the average first period of time is less than the average second period of time; and placing the second data in the fast-access storage medium, when the average second period of time is less than the average first period of time.Type: ApplicationFiled: March 6, 2014Publication date: February 5, 2015Inventors: Gary Quan, Basil Thomas, Richard Cadruvi, Kalindi Panchal, Bidin Dinesababu

Patent number: 8892611Abstract: A method, system, and apparatus for improving performance when retrieving data from one or more storage media. Files to be stored on the one or more storage media are classified into a ranking of different sets. Differences in retrieval value of different regions of the one or more storage media are exploited by selecting which files to store in which regions. For example, files that have a higher classification are stored in regions with faster retrieval values. The files can be classified based on frequency of access. Thus, files that are more frequently accessed are stored in regions that have a faster retrieval value. The files can be classified by another measure such as priority. For example, the classification for some or all of the files can be based on user-assigned priority. The classification may be based on events or data grouping.Type: GrantFiled: December 17, 2010Date of Patent: November 18, 2014Assignee: Condusiv Technologies CorporationInventors: Craig Jensen, Andrew Staffer, Robert Stevens Kleinschmidt, Jr., Sopurkh Khalsa, Gary Quan

Publication number: 20090132621Abstract: A method for selecting storage locations is provided. The method involves selecting storage locations for file storage by matching the speed and/or longevity of the storage locations with the frequency of access of the file type of the file, or the frequency of access of the file itself. The method allows for optimized usage of storage locations by matching frequently accessed files with higher performing storage locations, storage devices or storage systems.Type: ApplicationFiled: January 6, 2009Publication date: May 21, 2009Inventors: Craig Jensen, Basil Thomas, Gary Quan

Patent number: 7536504Abstract: A method for determining storage medium transfer rate characteristics. A host computer system issues a sequence of read commands to a storage medium to determine an accurate mapping of differences in transfer rate characteristics. For example, the host issues a sequence of relatively large reads to the storage medium at successively higher logical cluster numbers (LCNs). The host waits for each read command to complete before issuing the next read command and tracks a time interval that is representative of the time between completions of read commands.Type: GrantFiled: July 28, 2006Date of Patent: May 19, 2009Assignee: Diskeeper CorporationInventors: Robert Stevens Kleinschmidt, Jr., Craig Jensen, Sopurkh Khalsa, Andrew Staffer, Gary Quan

Patent number: 5927680Abstract: A gyro isolation assembly (10) is provided including a cradle (24) having a base (26) and a plurality of reinforcement wall portions extending therefrom (28, 30). A first bracket (50) is provided for supporting a first end of the cradle (24) in a suspended manner and a second bracket (50) is provided for supporting a second end of the cradle (24) in a symmetrical suspended manner. The center of the cradle assembly is attached to the mounting surface, forming the primary fixed attach point (43). Each end is then attached to the surface via the brackets (50) that allow compliance in one direction, but are stiff in the other two directions. A mounting structure (12) is provided for supporting a gyro therein. The mounting structure is suspended between the reinforcement wall portions (28) of the cradle (24). A plurality of isolators (34) are disposed between the mounting structure (12) and the cradle (24).Type: GrantFiled: July 1, 1997Date of Patent: July 27, 1999Assignee: McDonnell Douglas CorporationInventors: Timothy E.
