| Zusammenfassung: | PROBLEM TO BE SOLVED: To improve performance when update is centralized on a file whose segmentation is impossible. SOLUTION: Semantically dividable data are divided by a logic split device 24, and divided units are stored in another node 2. Thus, even when update requests from a client 3 are centralized on the units, the update requests can be distributed to those respective nodes 2 in which the divided units are stored. Therefore, it is possible to suppress the deterioration of the performance of the distributed file system 1. COPYRIGHT: (C)2010,JPO&INPIT |
