摘要： A synchronous data mirroring technique includes a log forwarding process and a consistency point (CP) process. During log forwarding, a source storage server receives write requests from clients, creates a log entry for each request in nonvolatile memory, and transmits each log entry to a destination storage server at a mirror site. The destination storage server writes each log entry to a file. If a primary volume becomes inaccessible due to a failure, the file is used to produce an updated mirror volume. The CP process includes updating a primary volume based on the write requests, and updating the mirror volume to reflect the updated primary volume. The mirror volume is updated by transmitting CP data from the source storage server to the destination storage server, and using the CP data to update the mirror volume through a network administration layer and a storage layer in the destination storage server.

摘要翻译： 同步数据镜像技术包括日志转发过程和一致性点（CP）过程。 在日志转发期间，源存储服务器从客户端接收写入请求，为非易失性存储器中的每个请求创建日志条目，并将每个日志条目发送到镜像站点上的目标存储服务器。 目标存储服务器将每个日志条目写入文件。 如果由于故障导致主卷变得无法访问，则该文件用于生成更新的镜像卷。 CP进程包括基于写入请求更新主卷，并更新镜像卷以反映更新的主卷。 通过从源存储服务器发送CP数据到目标存储服务器，并使用CP数据通过目标存储服务器中的网络管理层和存储层更新镜像卷来更新镜像卷。
