Abstract: PROBLEM TO BE SOLVED: To enable a server, such as a filer, configured with a plurality of virtual servers, such as virtual filers (vfilers), to participate in a plurality of private network address spaces with potentially overlapping network addresses. SOLUTION: The selection of an appropriate vfiler is enabled in such a manner that a service request within a private address space is secure and distinct from other private address spaces supported by the filer. An IP space refers to each distinct address space in which the filer and its storage operating system participate. An IP space identifier is applied to translation procedures that enable the selection of a correct vfiler for processing an incoming request and the selection of an appropriate routing table for processing an outgoing request.

Abstract: PROBLEM TO BE SOLVED: To provide an architecture for providing ability to create and maintain the multiple instances of virtual servers such as virtual filers (vfiler) in one server such as a filer. SOLUTION: A vfiler is a logical partitioning of the network and storage resources of a filer platform to establish the instances of multi-protocol servers. Each vfiler is allocated a subset of dedicate units of storage resources such as volumes or logical sub-volumes (qtree) and one or more network address resources. Each vfiler is also allowed to perform shared access to the 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 perform access to certain storage resources for a requested file stored on the filer platform.
