Abstract: A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

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。

Abstract: One or more techniques and/or computing devices are provided for granular replication for data protection. For example, a first storage controller may host a first volume. A consistency group, comprising a subset of files, logical unit numbers, and/or other data of the first volume, is defined through a consistency group configuration. A baseline transfer, using a baseline snapshot of the first volume, is used to create a replicated consistency group within a second volume hosted by a second storage controller. In this way, an arbitrary level of granularity is used to synchronize/replicate a subset of the first volume to the second volume. If a synchronous replication relationship is specified, then one or more incremental transfer are performed and a synchronous replication engine is implemented. If an asynchronous replication relationship is specified, then snapshots are used to identify delta data of the consistency group for updating the replication consistency group.
Abstract translation: 提供一个或多个技术和/或计算设备用于数据保护的粒度复制。 例如，第一存储控制器可以托管第一卷。 通过一致性组配置来定义一致性组，其包括文件的子集，逻辑单元号和/或第一卷的其他数据。 使用第一个卷的基准快照的基准传输用于在由第二个存储控制器托管的第二个卷内创建复制的一致性组。 通过这种方式，可以使用任意级别的粒度将第一个卷的子集与第二个卷进行同步/复制。 如果指定了同步复制关系，则执行一个或多个增量传输并实现同步复制引擎。 如果指定了异步复制关系，则快照将用于标识一致性组的增量数据以更新复制一致性组。
