Abstract: A technique for managing access to files by different data storage systems includes a data storage system generating an E-FSID (export FSID) for a file system in addition to a conventional FSID and providing the E-FSID in file handles that the data storage system generates for providing clients with access to the file system. The E-FSID is shared between/among different data storage systems, with each data storage system including data for cross-referencing the E-FSID to a respective local FSID for the file system. Because the E-FSID for a file is the same across different data storage systems, file handles continue to work after failover, migration, and other transitions.

Abstract: The present invention discloses a method for transmitting messages to components in a wireless communication system using a server process. In an embodiment of the present invention, the wireless communication system is a set of interconnected nodes with a main circuit board connected to zero or more components. To transmit a message to a component in the wireless communication system, the message is first encapsulated with a reference label that is associated with a component to which the message is to be sent, i.e., destination component. Upon encapsulation, the message is then transmitted to a destination node, which is a node on which resides the destination component. At the destination node, a server process determines an address for the destination component using the reference label.
