Abstract
A preferred embodiment of the present invention provides an intelligent reference object (IRO), which is used to encapsulate address translation between shared address space (SAS) addresses and native system addresses. The IRO works with a shared persistent virtual storage system that provides address translation between SAS addresses and the underlying system. By encapsulating these addresses translations in an IRO, the preferred embodiment provides the ability to create and share persistent objects using single level store semantics. When a client accesses the data in a persistent object, the IRO corresponding to the persistent object provides any address translation and indirection needed to perform the access.
