<p>A storage controller that can maintain its performance and reduce power consumption and thereby realize large capacity and low power consumption, and a method for controlling such a storage controller are provided. The storage controller (2) includes: a plurality of nonvolatile memory modules (50) having a plurality of nonvolatile memory chips (500) for storing data from a host computer (20); and a nonvolatile memory control unit (51) for controlling data input to and output from the host computer by controlling a power source (515) for the nonvolatile memory modules; wherein when reading or writing data from or to a designated nonvolatile memory module at a specified time in response to a data read/write request from the host computer, the nonvolatile memory control unit controls the power source for only the designated nonvolatile memory module to be turned on.</p> |
