ABSTRACT:
A data storage system includes an uninterruptible power supply unit having a small capacity supplies electric power to devices even upon system power failure. Depending on a data write request from a user program, a control program stores the data into a disk cache buffer set in a main storage device. An asynchronous input/output (I/O) task writes the data stored in the disk cache buffer into a file of an external storage device asynchronously with processing of the control program. Upon power failure, the asynchronous I/O task saves the data of the disk cache buffer into a batched saving area of the external storage device, and before initialization of the system upon restoration of the power, the control program writes thus saved data into the file.
