ABSTRACT:
A real time stream server using a disk device data restoration scheme, capable of shortening a restoration time by maximally utilizing the available stream resources, while providing the same service as in a case of normal operation, without setting any limitation on a new stream connection request during the restoration of lost data of a disabled disk device on a spare disk. The operations of the real time stream server is controlled by using normal streams for data transfer and restoration streams for data restoration, where as many stream resources as necessary are allocated to the normal streams first, and then at least a part of remaining stream resources are allocated to the restoration streams.
