Abstract
An HDD array is extended in a high-speed AV information server and then a restructuring instruction (41) is generated and restructuring operation (42) is executed If a reproduction request (43) is issued to storage information which is being restructured information processing (44) for interrupting the restructuring operation is carried out and a display (29) of a region which is being restructured is passed so as to reproduce the storage information. At the end of reproduction (47) after executing the reproduction operation (46), the reproduction operation (48) is resumed to thereby allow the access even while storage information is being restructured.
Claims15
A high-speed AV information server comprising:
- a plurality of magnetic disk devices having recording regions storing AV information in division state inputted by way of a communication switching device;
- at least one CODEC terminals for inputting and outputting the AV information to and from the magnetic disk devices;
- and
- a management terminal controlling the magnetic disk devices and CODEC terminals and managing the recording regions of the magnetic disk devices;
- wherein the management terminal includes:
- a restructuring unit executing a restructuring operation of the AV information when another magnetic disk device is additionally extended;
- and
- an interruption processing unit for interrupting the restructuring operation when a reproduction request is issued from one of the CODEC terminals to the storage information which is under being restructured.
A method of extending a magnetic disk device to a high-speed AV information server comprising:
- storing AV information to a plurality of magnetic disk devices in division state;
- inputting and outputting the AV information to and from the magnetic disk devices;
- and
- executing a restructuring operation of the AV information when another magnetic disk device is additionally extended;
- and
- interrupting the restructuring operation when a reproduction request is issued to the storage information which is under being restructured.
