Publication number: 20240419363Abstract: Techniques are provided for compacting indirect blocks. For example, an object is represented as a structure comprising data blocks within which data of the object is stored and indirect blocks comprising block numbers of where the data blocks are located in storage. Block numbers within a set of indirect blocks are compacted into a compacted indirect block comprising a base block number, a count of additional block numbers after the base block number in the compacted indirect block, and a pattern of the block numbers in the compacted indirect block. The compacted indirect block is stored into memory for processing access operations to the object. Storing compacted indirect blocks into memory allows for more block numbers to be stored within memory. This improves the processing of access operations because reading the block numbers from memory is faster than loading the block numbers from disk.Type: ApplicationFiled: August 26, 2024Publication date: December 19, 2024Inventors: Ananthan Subramanian, Kumaran Nagappen, Sriram Venketaraman, Szu-Wen Kuo, Yong Eun Cho

Publication number: 20240184470Abstract: Techniques are provided for providing a storage abstraction layer for a composite aggregate architecture. A storage abstraction layer is utilized as an indirection layer between a file system and a storage environment. The storage abstraction layer obtains characteristic of a plurality of storage providers that provide access to heterogeneous types of storage of the storage environment (e.g., solid state storage, high availability storage, object storage, hard disk drive storage, etc.). The storage abstraction layer generates storage bins to manage storage of each storage provider. The storage abstraction layer generates a storage aggregate from the heterogeneous types of storage as a single storage container. The storage aggregate is exposed to the file system as the single storage container that abstracts away from the file system the management and physical storage details of data of the storage aggregate.Type: ApplicationFiled: January 22, 2024Publication date: June 6, 2024Inventors: Ananthan Subramanian, Sriram Venketaraman, Ravikanth Dronamraju, Mohit Gupta

Publication number: 20240143549Abstract: Techniques are provided for an object file system for an object store. Data, maintained by a computing device, is stored into slots of an object. The data within the slots of the object is represented as a data structure comprising a plurality of nodes comprising cloud block numbers used to identify the object and particular slots of the object. A mapping metafile is maintained to map block numbers used to store the data by the computing device to cloud block numbers of nodes representing portion of the data stored within slots of the object. The object is stored into the object store, and the mapping metafile and the data structure are used to provide access through the object file system to portions of data within the object.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Inventors: Tijin George, Jagavar Nehra, Roopesh Chuggani, Dnyaneshwar Nagorao Pawar, Atul Ramesh Pandit, Anil Kumar Ponnapur, Jose Mathew, Sriram Venketaraman

Patent number: 11928350Abstract: A method, a computing device, and a non-transitory machine-readable medium for managing modes of operation for volumes in a node. A first portion of a plurality of volumes in a node is selected to operate in an active mode. A second portion of the plurality of volumes in the node is selected to operate in a passive mode. The second portion of the volumes that operates in the passive mode consumes fewer resources than the first portion of the volumes that operates in the active mode. The first portion of the plurality of volumes and the second portion of the plurality of volumes are adjusted over time based on activity of each volume of the plurality of volumes.Type: GrantFiled: September 15, 2022Date of Patent: March 12, 2024Assignee: NETAPP, INC.Inventors: Sushrut Bhowmik, Amit Panara, Sumith Makam, Vinay Kumar, Varun Simhadri, Sriram Venketaraman
