Abstract:
1. A file system for a computer, the file system comprising: N storage devices, where N is an integer greater than zero; N primary file servers, each file server being operatively connected to a corresponding storage device for accessing files therein; and a secondary file server operatively connected to at least one of the N storage devices; wherein upon a failure of one of the N primary file servers, one of the N storage devices switches its connection to the secondary file server and one or more of the storage devices that have not switched switch their connections to a primary file server other than the failed file server as necessary so as to prevent a loss in performance and to provide each storage device with an operating file server in a one-to-one relationship.
