摘要： The present invention provides selective migration in a storage network in accordance with a policy. The policy can include rules that establish which objects are migrated from a source file server to a destination file server based on file attributes (e.g., file type, file size, last access time, frequency of access). For example, large multimedia files that consume I/O bandwidth on expensive or critical file servers, without adding much value to enterprise productivity, can be migrated to a commodity or less critical file server.
摘要翻译：本发明根据策略提供了在存储网络中的选择性迁移。该策略可以包括基于文件属性（例如，文件类型，文件大小，最后访问时间，访问频率）确定哪些对象从源文件服务器迁移到目的地文件服务器的规则。例如，在昂贵的或关键的文件服务器上消耗I / O带宽的大型多媒体文件，而不增加企业生产力的价值，可以迁移到商品或不太关键的文件服务器。

摘要： Systems and methods to customize a namespace using a synthetic namespace. A NAS switch provides file migrations in a NAS storage network that are transparent to the clients. The NAS switch file handles are used to customize a namespace. More specifically, a synthetic namespace is generated from one or more file location tables that map the switch file handles to NAS file handles. The NAS file handles are independent of a physical export containing the objects referred to by the NAS file handles. In one example, the synthetic namespace presents a home directory corresponding to a location of a user.
摘要翻译：使用合成命名空间来定制命名空间的系统和方法。 NAS交换机提供对客户端透明的NAS存储网络中的文件迁移。 NAS交换机文件句柄用于自定义命名空间。更具体地说，从映射交换机文件句柄到NAS文件句柄的一个或多个文件位置表生成合成命名空间。 NAS文件句柄与包含NAS文件句柄所指对象的物理导出无关。在一个示例中，合成命名空间呈现对应于用户位置的主目录。

摘要： A system and method for parallel file system traversal using multiple job executors is disclosed. The system includes a pool of job executors, a job queue, and a trigger tracker. An object, representative of a node in the filesystem, is added (i.e., pushed) to the job queue for processing by an job executor. The job queue assigns (i.e., pops) objects to job executors in accordance to a LIFO (Last In First Out) ordering. Then the job executor performs an action such as copy. In one embodiment, the trigger tracker follows the processing of a child nodes to a particular child node. Thus, the filesystem is being traversed by several job executors at the same time.

摘要： A NAS (Network Attaches Storage) switch authenticates a client on multiple file servers for proxy services. The NAS switch enables proxy services by successively authenticating the client on the file servers using referrals. The NAS switch further comprises a connection manager to establish connections to the client and the file servers, a referral manager to redirect the client for successive authentications, and a transaction manager to perform data transfers with the file servers on behalf of the client. The system components support DFS (Distributed File System), and communicate using a protocol dialect that supports referral mechanisms such as NFSv4 (Network File Server version 4) or CIFS (Common Internet File System). The transaction manager also performs a protocol dialect translation service when the connection manager negotiates one protocol dialect with the client, and a different protocol dialect with the file server.
摘要翻译： NAS（网络连接存储）交换机对多个文件服务器上的客户端进行身份验证以进行代理服务。 NAS交换机通过使用转介依次验证文件服务器上的客户端来启用代理服务。 NAS交换机还包括连接管理器以建立到客户端和文件服务器的连接，引用管理器重定向客户端以进行连续的认证，以及事务管理器来代表客户端与文件服务器执行数据传输。系统组件支持DFS（分布式文件系统），并使用支持诸如NFSv4（网络文件服务器版本4）或CIFS（通用Internet文件系统）等引用机制的协议方言进行通信。当连接管理器与客户端协商一个协议方言时，事务管理器还执行协议方言转换服务，以及与文件服务器的不同协议方言。

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.
