Publication number: 20210303523Abstract: An illustrative data storage system is configured to replicate, from a source storage system to a target storage system, a pod that includes a file system constructed of block objects. The pod may be a storage system construct that groups storage entities within a namespace and supports operations on the storage entities as a group. The block objects may store metadata for individual files and directories of the file system and may support random read-write access to blocks of data associated with the files and directories of the file system.Type: ApplicationFiled: April 16, 2021Publication date: September 30, 2021Inventors: Subramaniam Periyagaram, Dirk Meister, Alexei Potashnik, Zoheb Shivani, Tejal Joshi Chakeres, Chu Zang, Ronald Karr

Publication number: 20210303522Abstract: An illustrative data storage system is configured to use pods to efficiently copy files systems constructed of block objects. In certain examples, the storage system generates, based on a pod that includes a file system constructed of block objects, a virtual copy of the pod such that modifications made to the pod (e.g., modifications to contents of the block objects by way of the pod) after the generation of the virtual copy of the pod are distinct from the virtual copy of the pod. In certain examples, the virtual copy of the pod is a writeable clone of the pod and modifications made to the clone (e.g., modifications to contents of the block objects by way of the clone) after the generation of the clone are distinct from the pod.Type: ApplicationFiled: January 29, 2021Publication date: September 30, 2021Inventors: Subramaniam Periyagaram, Dirk Meister, Zoheb Shivani, Ronald Karr

Publication number: 20210303528Abstract: An illustrative data storage system establishes path sets that represent relationships between service layer entities and storage layer entities associated with service layer entities. The data storage system coordinates, based on the path sets and on operations applied to one or more of the service layer entities, implementation of the operations on the storage layer entities. The path sets may be used to support implementation of snapshots, space accounting, and/or other operations of the data storage system.Type: ApplicationFiled: September 16, 2020Publication date: September 30, 2021Inventors: Dirk Meister, Subramaniam Periyagaram, David A. Grunwald, Ronald Karr

Publication number: 20210303519Abstract: An illustrative system is configured to optimize a transfer of a file system from a source storage system to a target storage system. For example, the system, in association with the transfer, determines that a copy of a collection of blocks containing data of block objects of the file system is already stored at the target storage system. In certain examples, an identifier referencing the collection of blocks is shared by the source and target storage systems and is used to determine that the copy of the collection of blocks containing data of block objects of the file system is already stored at the target storage system. The system uses the copy of the collection of blocks already stored at the target storage system instead of transferring the collection of blocks from the source storage system to the target storage system as part of the transfer.Type: ApplicationFiled: April 27, 2021Publication date: September 30, 2021Inventors: Subramaniam Periyagaram, Dirk Meister, Ronald Karr, Zoheb Shivani, Alexei Potashnik, Chu Zhang, Tejal Joshi Chakeres
