Publication number: 20240061603Abstract: Methods and systems for co-locating journaling and data storage are provided. Separate journal and volume partitions may be maintained within each logical storage unit (e.g., Logical Unit Number (LUN)) of a distributed storage system. Journaling of metadata associated with write requests received from one or more clients may be distributed by identifying a destination logical storage unit to which data associated with a given write request is to be stored and causing the data and metadata to be persisted to disk by journaling the metadata and the data to respective portions of an active log within the journal partition of the destination logical storage unit. By using the same logical storage unit for both journaling of write requests and writing the data associated with such write requests, the bottleneck due to there being only a single device or storage unit handling all metadata for all write requests can be avoided.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Applicant: NetApp, Inc.Inventors: Kevin Daniel Varghese, Ananthan Subramanian, Parag Sarfare, Sandeep Yadav, Suhas Urkude, Rajesh Khandelwal

Patent number: 11803316Abstract: A method and system for co-locating journaling and data storage based on write requests. A write request that includes metadata and data is received from a client. A logical storage unit for storing the metadata and the data is identified. The logical storage unit is divided into a journal partition and a volume partition. The journal partition includes a first log and a second log. Which of the first log and the second log is an active log and which of the first log and the second log is an inactive log are identified. The metadata is recorded in a first location in the active log and the data is recorded in a second location in the active log during a single I/O operation. A reply is sent to the client after the metadata and the data are recorded in the journal partition.Type: GrantFiled: July 19, 2022Date of Patent: October 31, 2023Assignee: NetApp, Inc.Inventors: Kevin Daniel Varghese, Ananthan Subramanian, Parag Sarfare, Sandeep Yadav, Suhas Urkude, Rajesh Khandelwal

Patent number: 10180871Abstract: The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.Type: GrantFiled: May 23, 2016Date of Patent: January 15, 2019Assignee: NetApp Inc.Inventors: Todd Mills, Suhas Urkude, Kyle Sterling, Atul Goel

Patent number: 8612702Abstract: Computer-implemented methods, systems, and computer-readable media for performing optimized backups of multiple volumes are disclosed. In one example, an exemplary method for performing such a task may comprise: 1) identifying a plurality of volumes, 2) prior to backing up the plurality of volumes, obtaining information that indicates that at least one volume within the plurality of volumes comprises at least one shared region of memory that is identical to a region of memory on at least one other volume within the plurality of volumes, and 3) when creating backups of the plurality of volumes, backing up each shared region of memory a single time so that the backups of the plurality of volumes share a single copy of each shared region of memory.Type: GrantFiled: March 31, 2009Date of Patent: December 17, 2013Assignee: Symantec CorporationInventors: Sasidharan Krishnan, Suhas Urkude

Patent number: 8417907Abstract: Prior to overwriting a block of data in a first volume of data on a primary host, the block of data is written to a first snapshot of the first volume. Subsequently, the first snapshot can be synchronized with a snapshot of a second volume of data on a secondary host, where the second volume is a replica of the first volume. To synchronize the snapshots, only a portion of the first snapshot (e.g., the block of data that was written to the first snapshot) is sent to the secondary host.Type: GrantFiled: October 29, 2009Date of Patent: April 9, 2013Assignee: Symantec CorporationInventors: Suhas Urkude, Sasidharan Krishnan

Patent number: 8281093Abstract: A computer-implemented method for creating consolidated backups of snapshot hierarchies may include identifying a hierarchy of snapshots. The computer-implemented method may also include copying data in a root snapshot of the hierarchy to a backup. The computer-implemented method may further include, for each child snapshot in the hierarchy, copying valid data in the child snapshot to the backup. The computer-implemented method may additionally include copying information that identifies a parent of the child snapshot to the backup. Various other methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: November 30, 2009Date of Patent: October 2, 2012Assignee: Symantec CorporationInventors: Sasidharan Krishnan, Suhas Urkude

Patent number: 8191063Abstract: A logical container may be created to facilitate the quick and efficient migration of one or more virtual machines from a source server to a destination server. The logical container may contain all of the files and state information related to the one or more virtual machines. The one or more virtual machines may be migrated by dismounting the logical container from a source server and mounting the logical container to a destination server. A management service may be include to facilitate batch migration of multiple virtual machines from a source server to a destination server.Type: GrantFiled: September 30, 2007Date of Patent: May 29, 2012Assignee: Symantex CorporationInventors: Randall Shingai, Suhas Urkude
