Abstract
A data storage resource is identifiable by physical addresses, and optionally by a virtual address. A policy defines which resources are accessible and which resources are not accessible. A request to access a resource is allowed if access to the resource is permitted by the policy, and if carrying out the access will not cause virtual addresses to be assigned to resources to which the policy disallows access. Since resources to which access is disallowed do not have virtual addresses, certain types of access requests that identify a resource by a virtual address can be allowed without consulting the policy.
