Abstract: The present invention provides a system and method of workstation configuration that includes a multi-level hierarchy management of preferences which are essentially managed and stored with a file server, rather than with each individual workstation. The invention comprises a computer network that includes workstations that have configurable hardware devices and software applications; a workstation server connected to the workstations that includes hierarchical preference files containing configuration information; and a preference manager for providing a coalesced, or merged, set of configuration parameters to the workstations based on the information in the hierarchical preference files.

Abstract: A hierarchical cache system comprises first and second pluralities of data caches and first and second respective higher level caches. The first higher level cache is coupled to the first plurality of caches and stores data of the first plurality of caches. The second higher level cache is coupled to the second plurality of caches and stores data of the second plurality of caches. First and second storage controllers access first and second respective address ranges from a main memory and the higher level cache subsystems. The first higher level cache responds to a request for data not contained in the first higher level cache by determining which of the address ranges encompasses the requested data and forwarding the request to the storage controller which can access the determined address range.
