摘要： An architecture provides the ability to create and maintain multiple instances of virtual servers, such as virtual filers (vfilers), within a server, such as a filer. A vfiler is a logical partitioning of network and storage resources of the filer platform to establish an instance of a multi-protocol server. Each vfiler is allocated a subset of dedicated units of storage resources, such as volumes or logical sub-volumes (qtrees), and one or more network address resources. Each vfiler is also allowed shared access to a file system resource of a storage operating system. To ensure controlled access to the allocated and shared resources, each vfiler is further assigned its own security domain for each access protocol. A vfiler boundary check is performed by the file system to verify that a current vfiler is allowed to access certain storage resources for a requested file stored on the filer platform.

摘要： A technique efficiently creates and serves a backup data set on a backup filer located at a remote site from a primary filer by essentially moving an entire operating environment of a primary data set to the backup filer. The primary filer is organized into one or more virtual filers (vfilers), one of which (the primary vfiler) is configured to serve data, such as the primary data set, for a client. In the event that the primary filer or primary vfiler becomes unavailable, the technique may be implemented as a disaster recovery or data migration sequence to enable efficient instantiation of a backup vfiler to serve the backup data set for the client.

摘要： A method for operating a server first assigns a plurality of storage volumes to one or more storage devices. A plurality of sub-volumes is established within a namespace of each of the plurality of storage volumes. An instance of a virtual server is created, the virtual server having a plurality of assigned sub-volumes, the assigned sub-volumes chosen from different storage volumes of the plurality of storage volumes. A file system function is shared between the server and the instance of the virtual server, the file system function using at least one of the plurality of assigned sub-volumes.

摘要： A system and method enables gradual transitioning of a server, such as a filer, to a new security domain and/or IP address scheme. A single physical platform may comprise multiple logical servers, such as virtual filers (vfilers), that simultaneously participate in different security domains and IP address schemes. Each logical server is allocated its own set of storage resources, such as volumes and qtrees, and network resources, such as network addresses. Additionally, a common set of storage resources may store a data set that is accessible to logical servers that participate in the different security domains and/or IP address schemes. Therefore, the server can transition from an old security domain to a new, e.g., upgraded, security domain, by gradually phasing out file access requests sent to a logical server in the old domain and redirecting those requests to a logical server in the new security domain. Similarly, the server can transition from an old IP address scheme to a new IP address scheme by gradually redirecting file access requests from one logical server to another. Since the invention enables multiple logical servers to access the server's data set, clients do not experience any downtime in service during the server's transition to a new security domain and/or IP address scheme.

摘要翻译： 系统和方法使得诸如文件管理器之类的服务器能够逐渐转变到新的安全域和/或IP地址方案。 单个物理平台可以包括同时参与不同安全域和IP地址方案的多个逻辑服务器，例如虚拟文件管理器（vfilers）。 每个逻辑服务器分配其自己的一组存储资源，如卷和qtree，以及网络资源，如网络地址。 此外，一组共同的存储资源可以存储可参与不同安全域和/或IP地址方案的逻辑服务器可访问的数据集。 因此，服务器可以通过逐渐淘汰发送到旧域中的逻辑服务器的文件访问请求，将这些请求重定向到新的安全性中的逻辑服务器，从而可以从旧的安全域过渡到新的，例如升级的安全域 域。 类似地，服务器可以通过逐渐将文件访问请求从一个逻辑服务器重定向到另一个逻辑服务器，从旧的IP地址方案转换到新的IP地址方案。 由于本发明使多个逻辑服务器能够访问服务器的数据集，所以在服务器转换到新的安全域和/或IP地址方案期间，客户端不会遇到服务中的任何停机时间。

摘要： A method for enabling a server configured with a plurality of virtual servers to participate in a plurality of private network address spaces and service requests within those address spaces is disclosed. Each virtual server is associated with an IPspace. Each network interface is tagged with an IPspace identifier (ID). Each virtual server is provided with one or more routing tables that control routing operations for requests processed by the virtual server. The IPspace ID is applied to translation procedures that enable selection of a virtual server to process an incoming request, and an appropriate routing table used to process an outgoing request.
