    摘要: A NAS switch provides mirroring in a NAS storage network that is transparent to client. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs mirroring of a namespace when during processes such as data migration, data replication, and data snapshot.

    摘要翻译: NAS交换机在对客户端透明的NAS存储网络中提供镜像。 源文件服务器将原始NAS文件导出,将源文件服务器上的对象位置指示到NAS交换机。 NAS交换机将原始的NAS文件句柄修改为内部文件系统,并将原始的NAS文件句柄映射到独立于位置的交换机文件。 NAS交换机将交换机文件句柄导出到客户端。 客户端查找对象,并使用交换机文件句柄将NAS请求发送到源文件服务器。 在数据迁移,数据复制和数据快照等过程中,NAS交换机执行命名空间的镜像。
