Abstract: Scale should be recognized as a primary factor influencing
        the architecture and implementation of distributed systems.
        This paper uses Andrew and Coda, distributed file systems 
        built at Carnegie Mellon University, to validate this
        proposition.
        Performance, operability and security are dominant
        considerations in the design of these systems.
        Availability is a further consideration in the design of 
        Coda.
        Client caching, bulk data transfer, token-based mutual
        authentication, and hierarchical organization of the 
        protection domain have emerged as mechanisms that enhance
        scalability.
        The separation of concerns made possible by functional
        specialization has also proved valuable in scaling.
        Heterogeneity is an important by-product of growth, but the
        mechanisms available to cope with it are rudimentary.
        Physical separation of clients and servers turns out to be 
        a critical requirement for scalability.
