ABSTRACT:
A system and method for managing access to assets in a distributed data storage system includes requesting, from a client computer, a lock from a server computer. The lock is evaluated using a bitwise comparison of the protected access modes and restricted access modes defined by the lock with the protected and restricted modes defined by the currently outstanding locks using an algorithm, such that a potentially large compatibility table is not needed.
