Abstract
A method and apparatus are provided for routing in an SAS expander for logical zoning. Common SAS topology defined by the ANSI T10 specification only relates to physical topology with multiple end devices, as well as to expander devices and the broadcast handling mechanisms in such physical topologies. The present invention introduces the concept of virtual topologies that can be non-overlapping or overlapping subsets of the physical topology and the routing mechanism that handles the routing issues with the virtual topologies.
