  abstract = {A fault tolerant parallel virtual file system is designed and
  implemented to provide high I/O performance and high reliability. A queuing
  model is used to analyze in detail the average response time when multiple
  clients access the system. The results show that I/O response time is with a
  function of several operational parameters. It decreases with the increase in
  I/O buffer hit rate for read requests, write buffer size for write requests
  and number of server nodes in the parallel file system, while higher I/O
  requests arrival rate increases I/O response time.}
