The Andrew File System
Developed at CMU to support all of its student computing.
Consists of workstation clients and dedicated file server machines.
Workstations have local disks, used to cache files being used locally (originally whole files, now 64K file chunks).
Andrew has a single name space -- your files have the same names everywhere in the world.
Andrew is good for distant operation because of its local disk caching: after a slow startup, most accesses are to local disk.
