Patent number: 11403188Abstract: A new snapshot of a storage volume is created by instructing computing nodes to suppress write requests. Storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot and finalizes and performs garbage collection with respect to segments allocated to the previous snapshot. Subsequent write requests to the storage volume are then performed on the segments allocated to the new snapshot. A segment maps segments to a particular snapshot and metadata stored in the segment indicates storage volume addresses of data written to the segment. The snapshots may be represented by a storage manager in a hierarchy that identifies an ordering of snapshots and branches to clone snapshots. Consistency points may be created by storage nodes transmitting sequence numbers assigned to write IOPs to the storage manager. Segments store the sequence numbers in metadata enabling rolling back to specific sequence numbers.Type: GrantFiled: December 4, 2019Date of Patent: August 2, 2022Assignee: ROBIN SYSTEMS, INC.Inventor: Jagadish Kumar Mukku

Patent number: 11256434Abstract: A new snapshot of a storage volume is created by suppressing write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot. Subsequent write requests to the storage volume are then performed on the segments allocated to the new snapshot. An orchestration layer implements a bundled application that is provisioned with storage volumes and containers. A snapshot of the application may be created and used to rollback or clone the application. De-duplication may be performed by creating a signature map and identifying duplicated blocks. Blocks of segments containing duplicated blocks are copied to pool segments and metadata of those segments of the same logical storage unit may be consolidated to pool metadata segments. The identification of duplicate blocks may be performed in a cloud computing platform.Type: GrantFiled: April 17, 2019Date of Patent: February 22, 2022Assignee: ROBIN SYSTEMS, INC.Inventors: Jagadish Kumar Mukku, Dhanashankar Venkatesan, Ripulkumar Hemantbhai Patel, Kallur Vasudeva Rao Narasimha Subban

Patent number: 11086725Abstract: A new snapshot of a storage volume is created by instructing computing nodes to suppress write requests. An orchestration layer implements a multi-role application that is provisioned with virtualized storage and computation resources. A snapshot of the application may be created and used to rollback or clone the application. Clones snapshots of storage volumes may be gradually populated with data from prior snapshots to reduce loading on a primary snapshot. A multi-role application may be orchestrated using multiple orchestration approaches and objects of the multi-role application may be discovered and added to an application definition. The application definition may be used to create snapshots of the application and the snapshot may be used to rollback, clone, backup, or migrate the application.Type: GrantFiled: March 25, 2019Date of Patent: August 10, 2021Assignee: Robin Systems, Inc.Inventors: Ravi Kumar Alluboyina, Tushar Doshi, Partha Sarathi Seetala, Ripulkumar Hemantbhai Patel, Jagadish Kumar Mukku

Patent number: 11023328Abstract: A new snapshot of a storage volume is created by suppressing write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot. Data is written in segments and Metadata is stored in the segments indicating LBAs of data stored therein and offsets within the segments at which data for LBAs are stored. For write requests, index entries are stored in an index buffer for a segment and written to the segment when the buffer is full. A redo entry is created in a redo buffer for multiple storage volumes and slices for each write request. Write requests are acknowledged when the redo buffer is written to redo segments on a storage device. On restart, index buffers are reconstructed from the redo segments if needed.Type: GrantFiled: July 30, 2018Date of Patent: June 1, 2021Assignee: ROBIN SYSTEMS, INC.Inventors: Dhanashankar Venkatesan, Jagadish Kumar Mukku, Ripulkumar Hemantbhai Patel

Patent number: 10976938Abstract: A new snapshot of a storage volume is created by suppressing write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot. Subsequent write requests to the storage volume are then performed on the segments allocated to the new snapshot. A block map records segments where current data for an LBA of a slice of a storage volume is stored. Block maps may be written to a storage device in order to free memory. Block maps may be read back into memory when needed. Writing and reading of block maps may be performed upon fragments of block maps. On restarting of the storage node, block maps may be restored from block maps stored in the storage device.Type: GrantFiled: July 30, 2018Date of Patent: April 13, 2021Assignee: ROBIN SYSTEMS, INC.Inventors: Jagadish Kumar Mukku, Dhanashankar Venkatesan, Ripulkumar Hemantbhai Patel

Patent number: 10877684Abstract: A distributed storage system stores a storage volume as segments that are allocated as needed and assigned VSIDs according to a monotonically increasing counter. The storage volume may be provisioned by an orchestration layer that manages the storage volumes as well as containers executing executable components of the storage volume. The storage volume may be replicated, such as by replicating slices of the storage volume. A primary copy of the slice may be moved from one node to another within the distributed storage system by designating it as a replica, creating a new replica at the new location which is then brought current. The new replica is then designated as the primary replica and the former primary replica may be deleted. A non-replicated storage volume may be converted to a replicated storage volume and vice versa.Type: GrantFiled: May 15, 2019Date of Patent: December 29, 2020Assignee: ROBIN SYSTEMS, INC.Inventors: Ripulkumar Hemantbhai Patel, Dhanashankar Venkatesan, Jagadish Kumar Mukku

Patent number: 10620871Abstract: An application executing on a first computing platform includes containers executing role instances. One or more logical storage volumes include segments allocated to the application and references in a mapping table. The mapping table indicates a tier ID corresponding to the computing platform on which each segment is located. A snapshot of the application may be restored on a second computing platform. The mapping table may be copied to the second computing platform and used without transferring segments from the first computing platform to the second computing platform. Reads will be routed to the first computing platform using the tier ID in the mapping table.Type: GrantFiled: November 15, 2018Date of Patent: April 14, 2020Assignee: ROBIN SYSTEMS, INC.Inventors: Jagadish Kumar Mukku, Kallur Vasudeva Rao Narasimha Subban

Patent number: 10599622Abstract: A distributed storage system stores a storage volume as segments that are allocated as needed and assigned VSIDs according to a monotonically increasing counter. The storage volume may be provisioned by an orchestration layer that manages the storage volumes as well as containers executing executable components of the storage volume. A storage volume may be stored across multiple tiers with a storage node managing on which tier a segment is stored based on a volume tier policy and usage of the segments. The tiering policy may be used to relocate the entire storage volume to a tier, such as a cloud computing platform, after which an application may be restored on the tier. Segments on a tier with built in redundancy may be used as both primary and backup copies.Type: GrantFiled: July 31, 2018Date of Patent: March 24, 2020Assignee: ROBIN SYSTEMS, INC.Inventors: Jagadish Kumar Mukku, Ravi Kumar Alluboyina, Dhanashankar Venkatesan
