Abstract
In a distributed file system, when a user requests a computer to create a distributed file, a management computer acquires a list of computers complying with an allocation rule selected by the user from allocation rules taking the performance, security level, reliability level and utility rate into consideration. When the user requests the computer to access the distributed file, on the other hand, the partial files and the server information are collected from each computer. Each computer evaluates the allocation of the partial files based on the selected allocation rule and the server information from each computer, and if required, selects a destination computer and instructs the partial files to be moved to the destination computer.
