Abstract
The current generation of file systems are inadequate
in facing the new technological challenges of wide area
networks and massive storage. xFS is a prototype file
system we are developing to explore the issues brought
about by these technological advances. xFS adapts
many of the techniques used in the field of high per­
formance multiprocessor design. It organizes hosts into
a hierarchical structure so locality within clusters of
workstations can be better exploited. By using an
invalidation­based write back cache coherence protocol,
xFS minimizes network usage. It exploits the file system
naming structure to reduce cache coherence state. xFS
also integrates different storage technologies in a uni­
