TECHNIQUE FOR ENABLING A PLURALITY OF VIRTUAL FILERS ON SINGLE FILER TO PARTICIPATE IN A PLURALITY OF ADDRESS SPACES WITH OVERLAPPING NETWORK ADDRESSES

摘要

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.
