Abstract
The present invention provides a data storage system and method. A controller is connected to a plurality of disk arrays, and each disk array is provided with a data protection unit for data protection. When one disk drive of one of the disk arrays is damaged, this disk array is defined as a damaged disk array, while other disk arrays without disk drives being damaged are defined as at least one normal disk array. The controller stops to write a new written data into the damaged disk array, while write the new written data into the normal disk arrays. The new written data will be protected by the data protection units of the normal disk arrays. Thereby, continuous data protection for the new written data by the data protection units together with preservation of storage performance of the system, after the disk drive is damaged, may be achieved.
