A data management apparatus and method, and more particularly to a data access management apparatus and method.

Generally, a storage device (such as a hard disk) is configured in a computer system or a server for accessing data. Moreover, whether or not an operation to access the storage device is required, power is supplied to the storage device to maintain the operation of the storage device. That is to say, when the storage device is in the working state, the storage device can be accessed by data, and when the storage device is in the standby state, it indicates that the storage device is waiting for the next data access.

For storing data to a storage device, most of the data with the same date will be stored in the same storage device. However, some data may be used less frequently and less frequently accessed, and the chances of storing the data for these data storage devices will be low.

Thereafter, the first processing unit 140 deletes the data in the first storage unit 130_1 according to the response signal, and generates a first processing signal, so that the enable signal generating unit 110 generates an enable signal to control the power supply unit 120 to generate, for example, a standby voltage. The voltage signal, in turn, controls the first storage unit 130_1 to switch to the standby state. That is to say, the first storage unit 130_1 is restored from the disabled state to the standby state. As such, the first storage unit 130_1 can perform using a standby voltage. It operates and is on standby to wait for the next data access operation, thereby maintaining the performance of the first server 250 for data access.

In addition, when the second processing unit 230 completes the storage operation, the second processing unit 230 may also control the second storage units 240_1~240_M that have stored the data of the first storage unit 130_1, for example, the second storage unit 240_1 enters the disabled state.
