Abstract
A data storage system includes: a storage device having a first storage and a physically separate second storage. A first core includes first data information related to first data to be written to the first storage, and a second core includes second data information related to second data to be written to the second storage. A shared memory is accessible by the first and second cores, and an emergency power system supplies backup power to the first and second cores when external power supplied to the data storage system is less than a minimum threshold operating power. When a write operation error of the second core is detected in a first mode, the first core writes the second data information to the first storage as third data information and writes the second data to the first storage as third data by referring to the second data information.
