Abstract

An information processing apparatus includes a first storage unit that has a power restricted state and an activated state, and a second storage that has a higher access speed than the first storage. A determination unit determines whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit. A control unit causes, in a state where data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and makes the first storage unit switch from the power restricted state to the activated state in a case where it is determined, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.

Claims

1. An information processing apparatus comprising:

a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which power is supplied;

a second storage unit that has a higher access speed than the first storage unit;

a determination unit configured to determine whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit; and

a control unit configured to cause, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and to make the first storage unit switch from the power restricted state to the activated state in a case where the determination unit determines, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.

2. The information processing apparatus according to claim 1, wherein in a case where the remaining storage capacity is not less than or equal to a predetermined threshold, the determination unit determines that the first storage unit need not be used, and in a case in which the remaining storage capacity is less than or equal to the predetermined threshold and a data write request to storage unit has occurred, the determination unit determines that the first storage unit needs to be used.

3. The information processing apparatus according to claim 1, wherein the control unit comprises:

a selection unit configured to select, when the data write request to storage unit occurs, a storage destination of the data from the first storage unit and the second storage unit based on a type and a size of the data; and

a storing unit configured to store target data of the write request in storage unit selected by the selection unit.

4. The information processing apparatus according to claim 3, wherein the selection unit selects, as the storage destination of the target data, the second storage unit with priority based on the type and the size of the target data.

5. The information processing apparatus according to claim 3, wherein the selection unit selects the second storage unit as the storage destination of the target data in a case where the size of the target data is smaller than a predetermined size.

6. The information processing apparatus according to claim 3, wherein the selection unit selects the second storage unit as the storage destination of the target data in a case where the target data is data set as high-access frequency type data.

7. The information processing apparatus according to claim 6, wherein the high-access frequency type data is set based on a type of a job to be executed in the information processing apparatus.

8. The information processing apparatus according to claim 6, wherein the high-access frequency type data includes data to be used for each execution of a job in the information processing apparatus and setting data of the information processing apparatus.

9. The information processing apparatus according to claim 3, wherein the storing unit temporarily accumulates data, for which the first storage unit has been selected as the storage destination, in the second storage unit while the first storage unit is in the power restricted state, makes the first storage unit switch from the power restricted state to the activated state when an amount of the accumulated data reaches a predetermined amount, and moves the accumulated data from the second storage unit to the first storage unit at once.

10. The information processing apparatus according to claim 1, wherein the control unit comprises

a decision unit configured to decide, among data stored in the second storage unit, a data candidate to save to the first storage unit, while the first storage unit is in the power restricted state,

a copy unit configured to make the first storage unit switch from the power restricted state to the activated state when the remaining storage capacity becomes less than or equal to a predetermined threshold, and to copy save candidate data decided by the decision unit from the second storage unit to the first storage unit, and

a deletion unit configured to delete the save candidate data from the second storage unit when a data write request to storage unit occurs.

11. The information processing apparatus according to claim 10, wherein the decision unit decides the save candidate data in accordance with a priority that has been set, on the data stored in the second storage unit, based on at least one of a data type, a data size, a data access frequency, and an elapsed time since the last access to the data occurred.

12. The information processing apparatus according to claim 10, wherein the copy unit sets a flag to the save candidate data stored in the second storage unit when copying the save candidate data to the first storage unit, and

the deletion unit deletes, from the second storage unit, the data to which the flag is set.

13. The information processing apparatus according to claim 1, wherein the first storage unit is an HDD and the second storage unit is an SSD.

14. An information processing apparatus comprising:

a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which the power is supplied;

a second storage unit that has a higher access speed than the first storage unit; and

a control unit configured to cause, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and to make the first storage unit switch from the power restricted state to the activated state in accordance with a remaining storage capacity of the second storage unit becoming less than a predetermined capacity while the first storage unit is in the power restricted state,

wherein the control unit controls write processing so as to write data in the second storage unit when the first storage unit is in the power restricted state, and to write data in the first storage unit after the first storage unit is switched to the activated state.

15. A control method of an information processing apparatus that comprises:

a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which power is supplied; and

a second storage unit that has a higher access speed than the first storage unit, the method comprising;

determining whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit; and

causing, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and of making the first storage unit switch from the power restricted state to the activated state in a case where it is determined in the determining, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.
