Abstract: One or more techniques and/or computing devices are provided for implementing synchronous replication. For example, a synchronous replication relationship may be established between a local storage controller hosting local storage and a remote storage controller hosting remote storage (e.g., replication may be specified at a file, logical unit number (LUN), or any other level of granularity). Data file operations may be implemented in parallel upon the local storage and the remote storage. Independent metadata file operations may be independently implemented from data file operations upon the local storage, and upon local completion may be remotely implemented upon the remote storage. In-flight data file operations may be drained before dependent metadata file operations are locally implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.
Abstract translation: 为实现同步复制提供了一个或多个技术和/或计算设备。 例如，可以在托管本地存储器的本地存储控制器和托管远程存储器的远程存储控制器之间建立同步复制关系（例如，可以在文件，逻辑单元号（LUN）或任何其他级别的粒度上指定复制 ）。 数据文件操作可以在本地存储器和远程存储器上并行实现。 独立的元数据文件操作可以从本地存储上的数据文件操作独立地实现，并且在本地完成时可以在远程存储器上远程实现。 在依赖的元数据文件操作在本地存储器上本地实现之前可以排空飞行中的数据文件操作，并且在本地完成时可以在远程存储器上远程实现。

Abstract: One or more techniques and/or computing devices are provided for non- disruptively establishing a synchronous replication relationship between a primary volume and a secondary volume and/or for resynchronizing the primary volume and the secondary volume. For example, a baseline snapshot and one or more incremental snapshots of the primary volume are used to construct and incrementally update the secondary volume with data from the primary volume. A dirty region log is used to track modifications to the primary volume. A splitter object is used to split client write requests to the primary volume and to the secondary volume. A synchronous transfer engine session is initiated to processing incoming client write requests using the dirty region log. A cutover scanner is used to transfer dirty data from the primary volume to the secondary volume. In this way, a synchronous replication relationship is established between the primary volume and the secondary volume.
Abstract translation: 提供了一种或多种技术和/或计算设备，用于不中断地建立主卷和次卷之间的同步复制关系和/或用于重新同步主卷和次卷。 例如，主卷的基准快照和一个或多个增量快照用于构建并增量更新来自主卷的数据的辅助卷。 脏区日志用于跟踪对主卷的修改。 分离器对象用于将客户端写请求分割为主卷和辅助卷。 启动同步传输引擎会话以使用脏区日志处理传入的客户端写入请求。 切换扫描器用于将脏数据从主卷传输到次卷。 这样，主卷和辅助卷之间就建立了同步复制关系。
