Patent number: 11570255Abstract: Systems and methods are disclosed for clients and servers operating in a scaled cluster environment. Efficiencies are introduced to the process of connecting a client to a clustered environment by providing the client with the ability to attempt a connection with multiple servers in parallel. Servers operating the in the clustered environment are also capable of providing persistent storage of file handles and other state information. Ownership of the state information and persistent handles may be transferred between servers, thereby providing clients with the opportunity to move from one server to another while maintaining access to resources in the clustered environment.Type: GrantFiled: March 2, 2020Date of Patent: January 31, 2023Assignee: Microsoft Technology Licensing, LLCInventors: David M. Kruse, Daniel E. Lovinger, Thomas E. Jolly, James T. Pinkerton, Mathew George, Roopesh C. Battepati, Mingdong Shang

Publication number: 20100185587Abstract: A data movement system is described herein that allows an administrator to cause data to be moved from one server to another with little or no service outage and in an amount of time that is proportional to the overall size of the data being moved rather than the way the data is organized. The system uses virtual hard drive technology to encapsulate the file system of a share within a single file of a host file system to allow snapshots taken at the volume level to avoid data unrelated to the share and to allow block level copy operations. The system also uses a motion process that includes steadily converging snapshots to copy data without interrupting access to the source location. The system provides tombstone notifications to clients that attempt to access the data at the source location after the data has moved.Type: ApplicationFiled: January 9, 2009Publication date: July 22, 2010Applicant: Microsoft CorporationInventor: Daniel E.

Patent number: 6647473Abstract: A snapshot system capable of capturing snapshots of multiple volumes wherein the snapshots are coordinated. A snapshot manager determines which volumes are to be involved in a snapshot operation, and issues a message to the file system for each volume involved, each message including information sufficient to identify the volumes involved in the snapshot operation. Each file system passes its respective message down to a coordinator mechanism. The coordinator mechanism coordinates the state of each of the volumes, such as by holding writes thereto, to put each volume into a quiescent state, and then enables the snapshot to be captured. When the snapshots are captured, a snapshot set will include snapshots that are coordinated across the multiple volumes. The coordinator mechanism releases any writes being held for the volumes involved.Type: GrantFiled: February 16, 2000Date of Patent: November 11, 2003Assignee: Microsoft CorporationInventors: David P.

Patent number: 6594674Abstract: A mechanism is provided that allows an application program to write, as a single file, a large block of data comprising multiple portions that could otherwise be written as several smaller files, then to access, as individual files, each of the portions within the large block of data, and to be able to create individual files efficiently out of each of these subfiles. The mechanism may be partially embodied in a file system that includes an information store defining each file on a volume. The application program writes, via the file system, a single file to the volume as (preferably) a contiguous block of data. The single file includes two or more separable streams of data capable of being stored as individual files (subfiles). Once the single file is written to the volume, multiple entries are made to the information store. Each entry defines and points to a subfile within the single file.Type: GrantFiled: June 27, 2000Date of Patent: July 15, 2003Assignee: Microsoft CorporationInventors: Keith S. Kaplan, Daniel E. Lovinger, A. Perry Clarke, Neil R. Kaethler, L. Felipe Cabrera
