    • Data transfer is performed to and from a host computer using a first block as the minimum unit. Data transfer is performed to and from a storage area using a second block as the minimum unit. A second block set of the storage area stores data obtained from performing data conversion processes that change the size of the data itself, with a first block set as the unit. Here a correspondence relationship is generated between the first block set and the second block set. In response to a read request from the host computer, a second block set, which corresponds to the first block set that includes the first block that is requested, is read, a reverse-conversion process is performed, and the data is sent to the host computer.
    • 使用第一块作为最小单位,从主计算机执行数据传送。 使用第二块作为最小单位,从存储区域执行数据传送。 存储区域的第二块组存储以执行改变数据本身的大小的数据转换处理获得的数据,以第一块为单位。 这里,在第一块组和第二块组之间产生对应关系。 响应于来自主计算机的读取请求,读取对应于包括所请求的第一块的第一块集的第二块集合,执行反向转换处理,并且将数据发送到 主机。
