Abstract
A computer system has a plurality of processors, each processor executing an independent operating system image without sharing file system state information. The system includes an active backplane coupled to the plurality of processors; and one or more data storage devices coupled to the active backplane for satisfying data requests from the plurality of processors, each of the data storage devices being adapted to secure a file when one processor writes to the file and to release the file when the processor completes operation on the file.
