Publication number: 20230273904Abstract: A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Also addressed is the use of distributed transactions in a map-reduce system; the use of local and distributed snapshots; replication, including techniques for reconciling the divergence of replicated data after a crash; and mirroring.Type: ApplicationFiled: April 18, 2023Publication date: August 31, 2023Inventors: Mandayam C. SRIVAS, Pindikura RAVINDRA, Uppaluri Vijaya SARADHI, Arvind Arun PANDE, Chandra Guru Kiran Babu SANAPALA, Lohit Vijaya RENU, Vivekanand VELLANKI, Sathya KAVACHERI, Amit Ashoke HADKE

Publication number: 20230185806Abstract: The disclosed embodiments include a method for caching by a data system. The method includes automatically caching a portion of a data object from an external data source to a local cluster of nodes in accordance with a unit of caching. The portion of the data object can be selected for caching based on a frequency of accessing the portion of the data object. The portion of the data object in the cache is mapped to the external data source in accordance with a unit of hashing. The method further includes, responsive to the data system receiving a query for data stored in the external data source, obtaining query results that satisfy the received query by reading the portion of the cached data object instead of reading the data object from the external data source.Type: ApplicationFiled: December 27, 2022Publication date: June 15, 2023Inventors: Jacques Nadeau, Tomer Shiran, Arvind Arun Pande, Thomas W.

Patent number: 11386044Abstract: A file server receives a request for data from a user device. The data is represented at the file server by a virtual cluster descriptor. The file server queries an identifier map using an identifier of the virtual cluster descriptor. Responsive to the identifier map indicating that the requested data is stored at a location remote from the file server, the file server accesses a cold tier translation table that stores a mapping between an identifier of each of a plurality of virtual cluster descriptors and a storage location of data associated with the respective virtual cluster descriptor. The cold tier translation table is queried using the identifier of the virtual cluster descriptor to identify a storage location of the requested data, and the data is loaded to the file server from the identified storage location.Type: GrantFiled: August 17, 2018Date of Patent: July 12, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Uppaluri Vijaya Saradhi, Arvind Arun Pande, Kanishk Rastogi, Giri Prasad Reddy Desireddygari, Nikhil Bhupale, Rajesh Boddu, Chandra Guru Kiran Babu Sanapala, Premkumar Jonnala, Ashish Sangwan

Patent number: 9646024Abstract: A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. A primitive storage layer (storage pools) knits together raw block stores and provides a storage mechanism for containers and transaction logs. Storage pools are manipulated by individual file servers. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents.
