Each data processor, shown as storage directors of a data storage peripheral system, includes a system configuration manager which is executed in each of the storage directors. Each system configuration manager determines status each time a shared resource, such as a random access memory (RAM) which can be a cache or disk data storage recorder, is analyzed by the system configuration manager. Messages between the storage directors and exchange of status are effected through the system configuration manager. These managers determine the status of the shared resource for ensuring serialization of access.
