Abstract:
A storage apparatus includes a first storage device that primarily stores data, a second storage device, having a property differing from the first storage device, that secondarily stores the data, and a control device that controls a data migration between the first storage device and the second storage device. The control device includes a storage section that stores attribute information on the data stored in the first storage device, a priority determination section which, based on the attribute information, determines a priority for the data migration from the first storage device to the second storage device, and a data migration section which, based on the priority, causes the data to migrate from the first storage device to the second storage device.
