摘要：
Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.
摘要（中）：
提供了一种包含根据存储区域属性来管理存储系统的带宽的多个存储系统的计算机系统。 计算机系统的特征在于：控制单元将相关文件信息合并在元数据中，所述相关文件信息包含用于识别由客户端计算机连接到第一文件的要被写入的第二文件的信息，以及 访问类型的写入权限。 控制单元参考相关的文件信息来获取第二文件和当客户端计算机访问第一个文件时的访问类型。 控制单元从存储在磁盘装置中的所获得的第二文件中读取与获得的访问类型对应的数据，以将读取的数据存储在高速缓冲存储器中。
