Publication number: 20230244395Abstract: This document describes techniques for storing virtual disk payload data. In an exemplary configuration, each virtual disk extent can be associated with state information that indicates whether the virtual disk extent is described by a virtual disk file. Under certain conditions the space used to describe a virtual disk extent can be reclaimed and state information can be used to determine how read and/or write operations directed to the virtual disk extent are handled. In addition to the foregoing, other techniques are described in the claims, figures, and detailed description of this document.Type: ApplicationFiled: March 27, 2023Publication date: August 3, 2023Applicant: Microsoft Technology Licensing, LLCInventors: John A. STARKS, Dustin L. GREEN, Todd William HARRIS, Mathew JOHN, Senthil RAJARAM, Karan MEHRA, Neal R. CHRISTIANSEN, Chung Lang DAI

Publication number: 20170060619Abstract: In an exemplary embodiment, a virtual disk file can be assigned an identifier and a virtual disk files that is dependent on the virtual disk file can include a copy of the identifier. In the instance that the virtual disk file is opened and data is modified that causes the contents of a virtual disk extent to change the identifier can be changed. If the virtual disk file and the dependent virtual disk file are used to instantiate a virtual disk the difference between identifiers can be detected, which is indicative of the fact that the virtual disk may be corrupted. Other techniques are described in the detailed description, claims, and figures that form a part of this document.Type: ApplicationFiled: November 10, 2016Publication date: March 2, 2017Inventors: John A.

Patent number: 8725782Abstract: This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.Type: GrantFiled: April 25, 2011Date of Patent: May 13, 2014Assignee: Microsoft CorporationInventors: John A. Starks, Dustin L. Green, Todd William Harris, Mathew John, Senthil Rajaram
