Data reconstruction method and system wherein timing of data of data reconstruction is controlled in accordance with conditions when a failure occurs
摘要：
A data storage system connectable to a host unit which issues data read/write requests to the data storage system, and which includes a plurality of disc units, and a controller connected to the disc units. A fault can occur in any of the disc units. The disc units store data in a plurality of data groups and error correcting data corresponding to each of the data groups. The controller, operable in different modes, performs processing of reconstructing data stored in any of the disc units in which a fault has occurred based on all other data belonging to any of the data groups to which the data to be reconstructed belongs and error correcting data corresponding to any of the data groups to which the data to be reconstructed belongs, and performs processing of data read/write requests from the host unit.
摘要（中）：

可连接到主机单元的数据存储系统，其向数据存储系统发出数据读/写请求，并且包括多个盘单元，以及连接到盘单元的控制器。 任何碟片单元都可能发生故障。 盘单元将数据存储在多个数据组中，并且对应于每个数据组的纠错数据。 控制器以不同的模式操作，根据属于重构数据所属数据组的所有其他数据所属的所有其它数据，以及纠错数据，执行重构存储在发生故障的任何一个盘单元中的数据的处理 对应于要重构的数据所属的任何数据组，并且执行来自主机单元的数据读/写请求的处理。
