Patent number: 11940969Abstract: Described are techniques for managing data locations of derived storage objects. The techniques include accessing a primary metadata tree providing a lookup path using a virtual address to locate data for a primary object in physical storage pointed to by a leaf node of the primary metadata tree and providing a sub-tree from a leaf node of the primary metadata tree associated with the primary object, the sub-tree providing lookup paths using virtual addresses for derived objects. Wherein a derived object is a view of the primary object at a specific point in time, with copy leaf nodes of the sub-tree pointing to stored data of the derived objects. The techniques further include maintaining an ancestry graph associated with the sub-tree with the ancestry graph linking derived object identifiers to provide an ancestral chain lookup to identify derived object identifiers of the closest stored physical data of a derived object.Type: GrantFiled: May 25, 2022Date of Patent: March 26, 2024Assignee: International Business Machines CorporationInventors: Ben Sasson, Lee Jason Sanders, Gordon Douglas Hutchison, William J.

Patent number: 11941458Abstract: Examples described herein relate to migrating a virtualized execution environment from a first platform to a second platform while retaining use of namespace identifiers and permitting issuance of storage transactions by the virtualized execution environment. The first platform can include a first central processing unit or a first network interface. The second platform can include a central processing unit that is different that the first central processing unit and a network interface that is the same or different than the first network interface. The second platform can retain access permissions and target media format independent of one or more identifiers associated with the migrated virtualized execution environment at the second platform. Unperformed storage transactions can be migrated to the second platform for execution.Type: GrantFiled: March 10, 2020Date of Patent: March 26, 2024Assignee: SK Hynix NAND Product Solutions Corp.Inventors: Jose Niell, Bradley A.

Patent number: 11928339Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected memory regions. Contiguous regions that share memory access attributes are merged, interleaved contiguous regions that share at least one nested attribute are defined into combined regions, and remaining regions are defined as separate independent regions. A memory protection unit (MPU) region size closest to a size of each defined region is identified. If the start address of each region aligns with the address structure of the MPU region size, then those regions are assigned to MPU regions having the MPU region size; otherwise, another MPU size that aligns with the size of the regions is selected and those regions are assigned to MPU regions having that size. Content is generated to configure settings of MPU regions of the programmable computing device for the merged contiguous regions, the combined region, and the independent regions.Type: GrantFiled: May 26, 2022Date of Patent: March 12, 2024Assignee: STMicroelectronics (Grand Quest) SASInventors: Frederic Ruelle, Michel Jaouen

Patent number: 11921593Abstract: A method for recovering files from a filesystem stored across sparse files in a cloud environment is described. According to the method, a data management system may receive a request to read the files. The data management system may identify one or more target address ranges corresponding to the files indicated via the request. The data management system may read index information for the sparse files in the cloud environment. The index information may indicate respective address ranges for data blocks within the sparse files. The data management system may identify one or more data blocks within one or more sparse files as corresponding to address ranges that overlap with the one or more target address ranges based on the index information. The data management system may transmit, to the cloud environment, one or more read requests for the identified one or more data blocks.Type: GrantFiled: April 27, 2022Date of Patent: March 5, 2024Assignee: Rubrik, Inc.Inventors: Abdullah Reza, Vijay Karthik
