Abstract: 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.

Abstract translation: 提供一个或多个技术和/或计算设备用于使用granset来管理任意一组存储项目。 例如，存储控制器可以托管多个存储项目和/或逻辑单元号码（LUN）。 存储项目的一个子集被分组到一致性组中。 创建一个granset用于跟踪，管理和/或提供对一致性组内的存储项目的访问。 例如，大规模集包括用于提供对存储项目的某些级别访问（例如，读取访问，写入访问，不访问）的应用程序编程接口（API）和/或属性，重定向操作以访问活动文件的数据 系统或快照，限制某些操作（例如，重命名和删除操作）和/或适用于一致性组内的每个存储项目的其他属性。 因此，granset提供了用于管理任意一组存储项目的持久磁盘布局。
