Robin Systems Assigned Two Patents

Multi-role application orchestration in distributed storage system
Robin Systems, Inc., San Jose, CA, a Rakuten Symphony Company, has been assigned a patent (11748203) developed by Alluboyina, Ravi Kumar, Santa Clara, CA, Vallala, Shravan Kumar, Mageswaran, Manjunath, San Jose, CA, and Doshi, Tushar, Santa Clara, CA, for a “multi-role application orchestration in a distributed storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A new snapshot of a storage volume is created by instructing computing nodes to suppress 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 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. 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. Clone snapshots of storage volumes may be gradually populated with data from prior snapshots to reduce loading on a primary snapshot.”

The patent application was filed on 2018-01-11 (15/868613).

Managing snapshot metadata following backup
Robin Systems, Inc., San Jose, CA, a Rakuten Symphony Company, has been assigned a patent (11740980) developed by Mukku, Jagadish, San Jose, CA, Singla, Nitin, Bangalore, India, and Narasimha Subban, Kallur Vasudeva Rao, Cupertino, CA, for “managing snapshot metadata following backup.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Snapshots are created of a unit of storage such that the snapshot includes all segments allocated to the unit of storage until a subsequent snapshot is created. A backup of a first snapshot may be performed by copying segments of the snapshot to backup storage. If a preceding snapshot has been backed up, those segments of the first snapshot are copied to backup storage without copying the segments of the preceding snapshot, otherwise all segments of the snapshot are copied. Metadata describing the snapshot may be retained but storage may be freed to be overwritten. The metadata may reference identifiers of segments copied to backup storage. Data stored in backup storage may also be labeled as individual segments or be associated with snapshot metadata in backup storage.”

The patent application was filed on 2020-09-22 (17/028891).
