ABSTRACT:
To receive a data input/output request from an information processor and writing data in a hard disk drive in accordance with the data input/output request, a storage array controller is provided with a circuit board having a nonvolatile memory functioning as a cache memory for storing the data to be read from or written in the hard disk drive and a circuit board mounting assembly to which the circuit board is removably mounted and in which the circuit board is provided with a removal information output circuit for outputting the circuit board removal information indicating that the circuit board is removed from the circuit board mounting assembly and a data erase circuit for erasing the data stored in the nonvolatile memory when the circuit board removal information is output from the removal information output circuit.
