Publication number: 20240104061Abstract: One or more techniques and/or computing devices are provided for managing an arbitrary set of storage items using a granset. For example, a storage controller may host a plurality of storage items and/or logical unit numbers (LUNs). A subset of the storage items are grouped into a consistency group. A granset is created for tracking, managing, and/or providing access to the storage items within the consistency group. For example, the granset comprises application programming interfaces (APIs) and/or properties used to provide certain levels of access to the storage items (e.g., read access, write access, no access), redirect operations to access either data of an active file system or to a snapshot, fence certain operations (e.g., rename and delete operations), and/or other properties that apply to each storage item within the consistency group. Thus, the granset provides a persistent on-disk layout used to manage an arbitrary set of storage items.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Devang Kundanlal Shah, Dipankar Roy, Krishnaveni Budati, Kai Tan, Pranab Patnaik, Akhil Kaushik

Patent number: 11797406Abstract: One or more techniques and/or computing devices are provided for moving a consistency group having a replication relation. For example, a first consistency group of storage objects (e.g., files, logical unit numbers (LUNs), etc.) within first storage may have a replication relationship with a second consistency group within second storage (e.g., the second consistency group is maintained as a synchronously replicated copy of the first consistency group). A volume copy operation, a single file move on demand command, a single file restore command, or other functionality is used to move the first consistency group from the first storage to third storage, such as for load balancing, to create a moved first consistency group within the third storage. A new replication relationship is established between the moved first consistency group and the second consistency group, and the moved first consistency group and the second consistency group are resynchronized.Type: GrantFiled: September 19, 2022Date of Patent: October 24, 2023Assignee: NetApp, Inc.Inventors: Pranab Patnaik, Nagender Somavarapu, Yuedong Mu, Rithin Kumar Shetty, Devang Kundanlal Shah
