Abstract:
1. A file storage system, comprising: a file server; an on-line storage medium; an off-line storage medium; a storage unit which prestores at least a startup time of the off-line storage medium; and a processing unit which is adapted to: upon receiving a write request for writing a stream file, acquire bit rate information included in the stream file, calculate a splitting position of the file based on the acquired bit rate information and the startup time of the off-line storage medium, and execute split arrangement of the file by storing a first part as a part of the file in the on-line storage medium while storing a second part as a remaining part of the file in the off-line storage medium based on the splitting position; and upon receiving a read request for reading out the stream file, read out the first part from the on-line storage medium and the second part from the off-line storage medium by starting up the off-line storage medium storing the second part.
