Description

  The present invention relates to an information processing apparatus, a control method therefor, and a program.

  Image forming apparatuses such as printers and MFPs include a secondary storage device for storing data such as image data and setting data. A typical secondary storage device is an HDD (Hard Disk Drive). Currently, in order to realize high performance of an image forming apparatus, it is considered to mount an SSD (solid state drive) having a high access speed as a secondary storage device in the image forming apparatus. In general, an SSD has a smaller storage capacity than an HDD and is more expensive than an HDD. For this reason, in order to realize high performance while compensating for the drawbacks of such SSDs, it has been studied to use SSDs and HDDs together in image forming apparatuses.

  Patent Document 1 proposes a technique for using both SSD and HDD. In Patent Document 1, a low-speed storage medium and a high-speed storage medium based on the frequency of access to data between a low-speed storage medium (HDD) having a low access speed and a high-speed storage medium (SSD) having a high access speed. Move data between. Specifically, among the data handled by the system, data with high access frequency is stored in a high-speed storage medium, and the remaining data is stored in a low-speed storage medium, thereby improving the performance of the entire system.

JP 2012-243117 A

  In general, an SSD has a limit on the number of times of rewriting a cell in which data is recorded. For this reason, when SSD and HDD are used in combination based on the frequency of access to data as described above, if the SSD is frequently accessed, the life of the SSD can be shortened (until the SSD breaks down). Period may be shorter). Further, when a TLC (triple level cell) is used instead of SLC (single level cell) or MLC (multilevel cell) as an SSD recording method, the life of the SSD can be significantly shortened. As described above, when the life of the SSD is shortened, the SSD may reach the end of its life before an information processing apparatus such as an image forming apparatus equipped with the SSD.

  The present invention has been made in view of the above problems. An object of the present invention is to provide a technique for enabling an information processing apparatus to operate even when an SSD mounted on the information processing apparatus reaches the end of its life.

  The present invention can be realized as an information processing apparatus, for example. An information processing apparatus according to an aspect of the present invention provides a first storage device, a second storage device having a higher access speed than the first storage device, and parameter values related to a lifetime of the second storage device.

<Controller>
FIG. 2 is a block diagram illustrating a configuration example of the controller 3. The controller 3 includes a main system (main board) 200 and a subsystem (sub board) 220. The main system 200 is a CPU system for controlling the entire MFP 1. The subsystem 220 is a CPU system connected to the main system 200 and configured with image processing hardware. The main system 200 is connected to the USB memory 209, the operation unit 5, the HDD 6, and the like. The subsystem 220 is connected to the scanner device 2, the printer device 4, the FAX device 7, and the like.

  The main system 200 includes a main CPU 201, a boot ROM 202, a memory 203, a bus controller 204, a nonvolatile memory 205, a disk controller 206, and an SSD (solid state drive) 207. The main system 200 further includes a USB controller 208, a network I / F (interface) 210, an RTC 211, and a power control unit 212.

  The main CPU 201 controls the entire main system 200 and the entire MFP 1. The boot ROM 202 stores a boot program executed by the main CPU 201 when the MFP 1 is activated. The memory 203 is used as a work memory for the main CPU 201. The bus controller 204 has a bridge function with an external bus (the bus on the subsystem 220 side in this embodiment). The nonvolatile memory 205 stores setting data used by the main CPU 201. The RTC 211 has a clock function.

  The disk controller 206 controls the HDD 6 and the SSD 207 corresponding to the secondary storage device (storage device) included in the MFP 1. The SSD 207 is a non-volatile storage device composed of a NAND flash memory, which is a semiconductor device, and can store data at a higher speed than the HDD 6 although it has a smaller storage capacity than the HDD 6. That is, the data write speed and read speed (access speed) for the SSD 207 are higher than those of the HDD 6. In the present embodiment, the HDD 6 is an example of a first storage device, and the SSD 207 is an example of a second storage device that has an access speed higher than that of the HDD 6.

  The power supply control unit 212 controls the power supply unit 10 of the MFP 1. The power supply unit 10 is a power supply that supplies power to each device in the MFP 1. The disk controller 206 can control the power supply from the power supply unit 10 of the MFP 1 to the HDD 6 and the SSD 207 by controlling the power supply control unit 212. The USB controller 208 controls USB devices such as the USB memory 209. The USB device may be detachable from the MFP 1.

  The sub system 220 includes a sub CPU 221, a memory 223, a bus controller 224, a nonvolatile memory 225, an image processor 226, and engine controllers 227 and 228. The sub CPU 221 controls the entire subsystem 220 under the control of the main CPU 201. The memory 223 is used as a work memory for the sub CPU 221. The bus controller 224 has a bridge function with an external bus (in this embodiment, a bus on the main system 200 side). The nonvolatile memory 225 stores setting data used by the sub CPU 221.

  The image processor 226 performs image processing on the image data output to the printer device 4 and the image data input from the scanner device 2. The engine controller 227 transfers image data between the image processor 226 and the printer device 4 and controls the printer device 4 in accordance with an instruction from the sub CPU 221. The engine controller 228 transfers image data between the image processing processor 226 and the scanner device 2 and controls the scanner device 2 in accordance with an instruction from the sub CPU 221. The FAX apparatus 7 is directly controlled by the sub CPU 221. Although not shown in FIG. 2 for simplification of description, the main CPU 201, the sub CPU 221 and the like include many CPU peripheral hardware such as a chip set, a bus bridge, and a clock generator.

  Next, an operation for realizing the copy function will be described as an example of the operation of the controller 3. When the user of the MFP 1 operates the operation unit 5 to instruct to copy an image, the main CPU 201 transmits a reading instruction to the scanner device 2 via the sub CPU 221. The scanner device 2 reads an image of a document according to the received instruction, generates image data, and inputs the generated image data to the image processor 226 via the engine controller 228. The image processor 226 temporarily stores the image data in the memory 223 by performing DMA transfer of the input image data to the memory 223 via the sub CPU 221. When the main CPU 201 confirms that a predetermined amount of image data or image data corresponding to all originals to be copied has been stored in the memory 223 based on the notification from the sub CPU 221, a print instruction is sent to the printer device 4 via the sub CPU 221. Send.

  The sub CPU 221 informs the image processor 226 of the storage position of the image data in the storage area of the memory 223. Thus, the image data on the memory 223 is transferred to the printer device 4 via the image processor 226 and the engine controller 227 in accordance with the synchronization signal output from the printer device 4. The printer device 4 prints an image on a sheet based on the image data transferred from the memory 223 in accordance with the received print instruction. Note that the image data temporarily stored in the memory 223 may be stored in the HDD 6. Accordingly, reprinting by the printer device 4 may be realized using image data stored in the HDD 6.

<Disk controller>
FIG. 3 is a diagram showing a configuration for access control of the HDD 6 and the SSD 207, which is executed by the disk controller 206 in the MFP 1, and shows functional blocks related to the access control. Here, an outline of the operation of the disk controller 206 that performs access control of the HDD 6 and the SSD 207 will be described with reference to FIG.

  In the MFP 1, when various jobs as described above are executed, a write access or a read access to the storage device (HDD 6 and SSD 207) occurs. When a write access to the storage device (that is, a data write request to the storage device) occurs, the main CPU 201 transmits a write command to the disk controller 206. Further, when a read access to the storage device (that is, a request to read data stored in the storage device) occurs, the main CPU 201 transmits a read command to the disk controller 206. The disk controller 206 controls reading or writing of data with respect to the storage devices (HDD 6 and SSD 207) according to the command received from the main CPU 201.

  When the disk controller 206 receives a read command for data stored in the HDD 6, the disk controller 206 reads out the data stored in the HDD 6 and transmits it to the main CPU 201. Further, when the disk controller 206 receives a read command for data stored in the SSD 207, the disk controller 206 reads out the data stored in the SSD 207 and transmits it to the main CPU 201. Further, when the disk controller 206 receives a write command and data to be written from the main CPU 201, the disk controller 206 stores the received data in either the HDD 6 or the SSD 207. At that time, the disk controller 206 stores data in either the HDD 6 or the SSD 207 by write control described later.

  As shown in FIG. 3, the disk controller 206 may be divided into a disk controller 206a and a disk controller 206b. The functions of the disk controller 206a and the disk controller 206b can be realized by a single disk controller 206.

  When a write access to the storage device occurs, the disk controller 206a selects (determines) the storage destination of the write access target data from the HDD 6 and the SSD 207 based on a predetermined condition. For example, the disk controller 206a can also specify the type of target data for write access (for example, image data or setting data), and select the storage destination of the target data based on the specification result.

  The disk controller 206b stores the target data in the storage destination selected by the disk controller 206a in accordance with an instruction from the disk controller 206a. The disk controller 206b also performs encryption processing of data to be written to the HDD 6 or SSD 207 and decryption processing of data read from the HDD 6 or SSD 207 as necessary. The disk controller 206b also has a function of performing data copying (mirroring) between the SSD 207 and the HDD 6.

  In the present embodiment, the disk controllers 206a and 206b perform control of writing data to the storage device so that data (low frequency data) determined as a type with low access frequency is stored in the HDD 6. Further, the disk controllers 206a and 206b perform control of writing data to the storage device so that data (high frequency data) determined as a type with high access frequency is stored in the SSD 207.

  Further, when a read access to the storage device occurs, the disk controller 206a instructs the disk controller 206b of data to be read by the read command. The disk controller 206b reads the data instructed from the disk controller 206a from the HDD 6 or the SSD 207 and transmits it to the main CPU 201.

<SSD characteristics>
FIG. 4 is a diagram showing an outline of characteristics of the NAND flash memory (NAND flash). As shown in FIG. 4A, the NAND flash memory used for the SSD includes SLC (single level cell), MLC (multilevel cell), and TLC (triple level cell) as data recording methods. . SLC, MLC, and TLC are recording systems that store 1 bit, 2 bits, and 3 bits per cell, respectively. Currently, SSDs that employ MLC are the mainstream, but SSDs that employ TLC, which is advantageous in terms of unit price and storage capacity, are spreading. However, SSL that employs TLC has a smaller number of cell rewritable times than other recording methods, and therefore, if it is frequently accessed, its life may be significantly shortened.

  In addition, in the NAND flash memory used for the SSD, data can be erased only in units of, for example, 512-byte blocks due to physical characteristics (402 in FIG. 4). For this reason, even when rewriting 16-byte data (401 in FIG. 4) by write access in the SSD, first, the data of one block (402 in FIG. 4) is read, the one block is erased, and then read. It is necessary to write back the data. As described above, even when a small amount of data is written, it is necessary to rewrite data in units of blocks, which affects the life of the SSD.

  As described above, when the life of the SSD 207 mounted on the MFP 1 becomes short, there is a possibility that the SSD 207 may reach the life before the MFP 1. When the SSD 207 reaches the end of its life, the data stored in the SSD 207 becomes unusable, which may prevent the MFP 1 from continuing operation.

<Overview of HDD and SSD control>
In this embodiment, in order to enable the operation of the MFP 1 even if the SSD 207 mounted on the MFP 1 reaches the end of its life, the HDD 6 and the data stored in the SSD 207 are backed up to the HDD 6 when the life of the SSD 207 approaches. The SSD 207 is controlled. Specifically, the disk controller 206 acquires a parameter value related to the life of the SSD 207 from the SSD 207, and determines the remaining life of the SSD 207 based on the acquired parameter value. Accordingly, the disk controller 206 monitors whether the life of the SSD 207 mounted on the MFP 1 is approaching. Further, the disk controller 206 controls the HDD 6 and the SSD 207 so that the data stored in the SSD 207 is backed up to the HDD 6 according to the determination result of the remaining life of the SSD 207.

  As a result, before the SSD 207 reaches the end of its life, the data stored in the SSD 207 can be backed up to the HDD 6. That is, even if the SSD 207 mounted on the MFP 1 reaches the end of its life, the operation of the MFP 1 can be performed by using the data backed up on the HDD 6.

<Procedure for controlling HDD and SSD>
FIG. 5 is a flowchart illustrating an example of a control procedure of the HDD 6 and the SSD 207 executed by the disk controller 206. Note that the processing of each step shown in FIG. 5 may be realized by hardware such as FPGA or ASIC, or may be realized by software. When implemented by software, each process may be implemented by a processor (not shown) in the disk controller 206 or a process in which the main CPU 201 reads and executes a control program stored in the HDD 6 or the like.

  When the MFP 1 is activated from the power-off state, the disk controller 206 confirms the remaining life of the SSD 207 in S101. Specifically, the disk controller 206 acquires SMART (Self Monitoring Analysis And Reporting Technology) information of the SSD 207 from the SSD 207. The SMART information is stored in the SSD 207 and includes, for example, information (parameter values) related to an error rate, a rotation speed (in the case of an HDD), energization time, and life.

  The life of the SSD 207 is indicated by, for example, the total data amount (total write amount) that can be written before the SSD 207 reaches the end of its life. This total writing amount is stored in advance in the SSD 207 or the like and used by the disk controller 206. In the present embodiment, the disk controller 206 acquires the amount of data written so far in the SSD 207 as information (parameter value) related to the life of the SSD 207 from the SMART information. The disk controller 206 determines the remaining life of the SSD 207 based on the data amount indicated by the acquired parameter value and the total write amount of the SSD 207. Specifically, the disk controller 206 determines the remaining amount of data that can be written until the SSD 207 reaches the end of its life with respect to the total write amount (that is, the difference between the total write amount and the data amount indicated by the acquired parameter value). The percentage is determined as the remaining life.

  If the remaining life of the SSD 207 is confirmed, then in S102, the disk controller 206 determines whether the remaining life is below the threshold Th1. The threshold value Th1 is determined in advance as a threshold value for determining whether the remaining life of the SSD 207 is slight. When the remaining life falls below the threshold Th1, the disk controller 206 determines that the remaining life of the SSD 207 is very small and advances the process to S103.

  In S103, the disk controller 206 performs backup of the data by copying the data stored in the SSD 207 to the HDD 6. As a result, even if the SSD 207 reaches the end of its life and then fails, the MFP 1 can operate by using the data backed up in the HDD 6. The disk controller 206 stops the power supply to the SSD 207 after data backup. Thereby, the power consumption of the MFP 1 can be reduced. Thereafter, the disk controller 206 ends the process.

  On the other hand, if the remaining life is not less than the threshold Th1 in S102, the disk controller 206 advances the process to S104. In S104, the disk controller 206 determines whether or not the remaining life is below the threshold Th2. The threshold value Th2 is set in advance to a value higher than the threshold value Th1 as a threshold value for determining whether the SSD 207 is likely to break down in the near future. The threshold value Th2 can be set to a value corresponding to a data amount of 1 / N (for example, N = 10) of the total write amount. When the remaining life falls below the threshold Th2, the disk controller 206 determines that the SSD 207 is likely to fail in the near future, and advances the process to S105.

  In S105, the disk controller 206 copies the data stored in the SSD 207 to the HDD 6, thereby backing up the data and continuing the power supply to the SSD 207. Thereafter, the disk controller 206 ends the process. As a result, it is possible to prepare for the case where the SSD 207 reaches the end of its life and the time when the SSD 207 has failed is earlier than expected. In such a case, the MFP 1 can operate by using the data backed up in the HDD 6. . Thereafter, the disk controller 206 ends the process.

  In S104, if the remaining life is not less than the threshold Th2 (that is, if there is room in the remaining life of the SSD 207), the disk controller 206 ends the process without performing data backup. However, the disk controller 206 may back up the data stored in the SSD 207 to the HDD 6 as in S103 or S105 from the viewpoint of data protection.

  Note that the processing according to the flowchart of FIG. 5 is repeatedly executed at regular time intervals, for example, during the operation of the SSD 207. In addition, the disk controller 206 stops the power supply to the SSD 207 in S103, and when the SSD 207 is replaced with a new SSD after stopping the operation of the SSD 207, the data copied to the HDD 6 is restored to the new SSD. May be.

  FIG. 6 is a diagram showing an example of control by the disk controller 206 described above. As long as the remaining life of the SSD 207 does not fall below the threshold Th1, the disk controller 206 controls the writing of data to the storage device so that the low frequency data is stored in the HDD 6 and the high frequency data is stored in the SSD 207 as described above. Do. The low frequency data is stored in the HDD operation area (first storage area) of the HDD 6.

  FIG. 6A shows the control by the disk controller 206 when the remaining life of the SSD 207 falls below the threshold Th2 (“YES” in S104). In this case, the disk controller 206 copies the data stored in the SSD 207 to the SSD save area (second storage area) of the HDD 6. After that, the disk controller 206 controls data writing so that the low frequency data is stored in the HDD operation area of the HDD 6 and the high frequency data is stored in the SSD 207 as before.

  FIG. 6B shows control by the disk controller 206 when the remaining life of the SSD 207 falls below the threshold Th1 (“YES” in S102). In this case, the disk controller 206 copies the data stored in the SSD 207 to the SSD save area (second storage area) of the HDD 6. Thereafter, the disk controller 206 stops the power supply to the SSD 207 and performs data write control so that both the low frequency data and the high frequency data are stored in the HDD 6. Specifically, as shown in FIG. 6B, data write control is performed so that the low-frequency data is stored in the HDD operation area of the HDD 6 and the high-frequency data is stored in the SSD save area of the HDD 6. In this manner, data write control according to the type of data to be written to the storage device can be appropriately realized based on the remaining life of the SSD 207.

  As described above, in the MFP 1 of the present embodiment, the disk controller 206 acquires the parameter value related to the life of the SSD 207 from the SSD 207 and determines the remaining life of the SSD 207 based on the acquired parameter value. When the remaining life of the SSD 207 falls below the threshold Th2, the disk controller 206 copies the data stored in the SSD 207 to the HDD 6 and continues the operation of the SSD 207. Further, when the remaining life of the SSD 207 falls below the threshold Th1 (<Th2), the disk controller 206 copies the data stored in the SSD 207 to the HDD 6 and stops the operation of the SSD 207.

  Thus, according to the determination result of the remaining life of the SSD 207, the data stored in the SSD 207 is backed up before the SSD 207 reaches the life. As a result, even if the SSD 207 reaches the end of its life, the MFP 1 can operate by using the data backed up in the HDD 6.
