摘要

PPROBLEM TO BE SOLVED: To provide an RAID for reducing a storage capacity required for the redundancy of data, and improving the security of data, and efficiently using a line. PSOLUTION: Data are made redundant, and divided into a plurality of volumes, and a controller C for controlling the distribution and storage of the respective volumes in a plurality of storages S distributed and arranged through a network is provided with a path managing part 504 and a storage set managing part 505. The path managing part 504 calculates evaluation values indicating the values of the respective distributed and arranged storages as the objects to be used on the basis of band width, communication costs, and physical distances between a node for requesting writing and the storages. The storage set managing part 505 selects the plurality of storages as the optimal storage set from among the distributed and arranged storages on the basis of the evaluation values.

要解决的问题：提供一种RAID，以减少数据冗余所需的存储容量，提高数据安全性并有效地使用线路。

解决方案：使数据冗余，并分成多个卷，并且用于控制各个卷在通过网络分布和布置的多个存储器S中的分配和存储的控制器C设有路径管理部件504和存储集管理部件505。路径管理部件504基于带宽，通信成本和节点之间的物理距离来计算指示作为要使用的对象的，表示各个分布式存储设备的值的评估值。用于请求写入和存储。存储集管理部分505基于评估值从分配和布置的存储中选择多个存储作为最佳存储集。
