Technique for enabling multiple virtual filers on a single filer to participate in multiple address spaces with overlapping network addresses

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.
