Further, when the authorized user does not use the information processing apparatus 102, the cartridge apparatus 100 is removed from the information processing apparatus 102, so that the information processing apparatus 102 can be prevented from being illegally used.
[0033]
Hereinafter, a state in which the cartridge device 100 is removed from the information processing device 102 is referred to as an offline state for convenience of description.
[0034]
The above is the description of the appearance of the information processing system according to the embodiment of the present invention and the usage form of the user.
[0035]
Next, the configuration and operation of the information processing system according to the present embodiment will be described.
[0036]
FIG. 2 is a block diagram illustrating a schematic configuration of an information processing system according to the present embodiment. The information processing system includes hard disk devices 101a to 101d, a cartridge device 100 accommodating the hard disk devices 101a to 101d, and an information processing device. 102.
[0037]
The cartridge device 100 has a first control unit 200. The first control unit 200 is driven by a battery 206, and can execute a predetermined process in an offline state. The first control unit 200 includes an MPU 201, a cover sensor 202, an interface control unit 203, and a non-volatile memory 204 connected to each other via a bus 205.
[0038]
The MPU 201 has a built-in ROM 201a and executes a program stored in the ROM 201a to control the first control unit 200. Note that the ROM 201a also stores a program for implementing predetermined processing steps in the flowcharts shown in FIGS.
[0039]
The cover sensor 202 detects whether the cover 103 is open or closed. Since the cover sensor 202 is supplied with power from the battery 206, the cover sensor 202 can detect opening and closing of the cover 103 even in an offline state. The interface control unit 203 exchanges various information with the information processing apparatus 102 via the interface line 207.
[0040]
The non-volatile memory 204 stores a history of opening and closing of the cover 103 in the offline state (cover opening / closing history 226) and ID information 225 used for authentication with the information processing apparatus 102. The ID information 225 is acquired from a later-described second control unit 208 in the information processing apparatus 102 via the interface line 207, and is stored in the nonvolatile memory 204.
[0041]
With the above configuration, the cartridge device 100 can detect the opening and closing of the cover 103 and retain information such as the ID information 225 and the cover opening / closing history 226 without receiving power supply from the information processing device 102.
[0042]
The information processing apparatus 102 includes a second control unit 208, a third control unit 209, and a power supply unit 215 that supplies power to the second control unit 208 and the third control unit 209.
[0043]
Here, a startup procedure of the information processing apparatus 102 will be described.
[0044]
First, when a power switch (not shown) is turned on, power is supplied to the second control unit 208 via the power line 216, and the second control unit 208 is activated. The second control unit 208 activated by the power supply sends an instruction to the power supply unit 215 through the control line 230 to start the power supply from the power supply line 217 to the third control unit 209. The third control unit 209 having received the power supply performs various processes by loading and executing an operating system and application programs from the hard disks 101a to 101d.
[0045]
Next, the configurations of the second control unit 208 and the third control unit 209 will be described.
[0046]
The second control unit 208 includes an MPU 210, an interface control unit 212, and a non-volatile memory 211 connected to each other by a bus 213.
[0047]
The MPU 210 has a built-in ROM 210a, and controls the second control unit 208 by executing a program stored in the ROM 210a. Note that the ROM 210a also stores programs corresponding to the flowcharts shown in FIGS.
[0048]
The interface control unit 212 exchanges various information with the third control unit 209 via the interface line 214 and exchanges various information with the first control unit 200 via the interface line 207. Give and receive.
[0049]
The nonvolatile memory 211 stores ID information 227 and the like used when performing authentication with the cartridge device 100. Here, as the ID information 227 stored in the non-volatile memory 211, information input by a predetermined administrator from the operation panel 228 or information managed and received by a management device (not shown) on the network 229 is used. You may.
[0050]
In addition, the ID information 227 (225) may be automatically generated by the second control unit 208 or the third control unit 209. In the case of automatic generation, after the cartridge device 100 is mounted and authenticated, the ID information is changed to ID information different from the authenticated ID information, and is used as the ID information 227 (225). improves.
[0051]
The ID information 227 in the nonvolatile memory 211 is sent to the first control unit 200 by the interface control unit 212 when the administrator operates the operation panel 228. The first control unit 200 stores the received ID information 227 in the nonvolatile memory 204 as ID information 225.
[0052]
When the ID information 227 is automatically generated or changed by the second control unit 208 or the third control unit 209, the ID information 227 is generated based on an operation of the operation panel 228. It is desirable to save time and effort on the user by automatically transmitting and storing the data to the non-volatile memory 204 without transmitting the data to the nonvolatile memory 204.
[0053]
The operation panel 228 has operation buttons and a display (not shown), accepts operations by the operation buttons, and displays a guide message on the display.
[0054]
Further, the second control unit 208 has a function of detecting that the cartridge device 100 is mounted on the information processing device 102. For example, when the cartridge device 100 is mounted on the information processing apparatus 102, the mounting detection function detects a change in the signal level by setting a part of the signal line of the interface line 207 to be terminated from open to ground. This can be achieved by doing
[0055]
The third control unit 209 includes an MPU 218, a disk controller 219, a RAM 220, a ROM 221, an interface control unit 222, and a network control unit 223 connected to each other via a bus 224.
[0056]
The MPU 218 controls the third control unit 209 by expanding a program or the like stored in the ROM 221 into the RAM 220 and executing the program. Note that the ROM 221 also stores a program for realizing predetermined processing steps in the flowcharts shown in FIGS.
[0057]
The interface control unit 222 exchanges information with the second control unit 208 via the interface line 214. The disk controller 219 performs RAID control on a disk array including the hard disk devices 101a to 101d connected via a disk interface 224 (for example, a serial ATA interface).
[0058]
A program loaded from the hard disk devices 101a to 101d is also appropriately loaded in the RAM 220, and this program is executed by the MPU 218. The ROM 221 also stores a BIOS program that is executed first by the MPU 218 after the third control unit 209 is started. This BIOS program loads the operating system stored in the hard disk devices 101a to 101d into the RAM 220.
[0059]
The network control unit 223 controls data communication performed with another device via the network 229.
[0060]
Note that, as described above, the configuration in which the control unit of the information processing apparatus 102 is divided into the first control unit 208 and the second control unit 209 is implemented by receiving a BIOS program from another manufacturer. This is useful for a manufacturer who manufactures the information processing apparatus 102 according to the present invention, and who has difficulty in modifying this BIOS program into a desired mode.
[0061]
Next, an operation when the second control unit 208 activates the third control unit will be described with reference to the flowchart of FIG.
[0062]
The MPU 210 of the second control unit 208 first determines whether or not the cartridge device 100 has been mounted on the information processing device 102 based on the program stored in the ROM 210a (step S301), and the cartridge device 100 has been mounted. Otherwise, the process proceeds to step S302.
[0063]
In step S302, the interface control unit 212 acquires ID information 225 from the nonvolatile memory 204 of the first control unit 200. In step S303, the ID information 225 acquired in step S302 is collated with the ID information 227 held in the information processing device 102 (the non-volatile memory 211), and it is determined whether the two match. As a result, if they do not match, the process proceeds to step S304.
[0064]
In step S304, an authentication operation by the user is requested, and it is determined whether or not the user is a valid user based on the authentication information input from the operation panel 228. The authentication information to be input may be the ID information 227 or a password stored in the nonvolatile memory 211 in advance.
[0065]
In step S305, it is determined whether or not the authentication in step S304 is successful. If the authentication is successful, the process proceeds to step S307, in which the power supply to the third control unit 209 is started to start the third control unit. 209 is started.
[0066]
If the authentication in step S304 fails, the process proceeds to step S306, a warning message to that effect is displayed on the display of the operation panel 228, and the process ends.
[0067]
If it is determined in step S303 that the ID information 225 acquired in step S302 matches the ID information 227 held in the information processing apparatus 102, the process proceeds to step S307, and the third control unit 209 is set as described above. The third control unit 209 is activated by starting power supply to the third control unit 209.
[0068]
When the third control unit 209 is started by the second control unit 208, it immediately supplies power to the hard disk device 101 to start the hard disk device 101, and executes the operating system stored in the hard disk device 101. Load into RAM 220.
[0069]
As described above, in the first embodiment, when a plurality of hard disk devices 101 are used as a disk array device, the information processing device 102 can acquire the storage contents in the cartridge device 100 that accommodates the disk array device. A nonvolatile memory 204 is provided, and ID information 225 for authenticating a pair with the information processing device 102 is stored in the nonvolatile memory 204. On the other hand, the information processing apparatus 102 obtains the ID information 225 from the non-volatile memory 204 of the mounted cartridge apparatus 100, compares the acquired ID information 225 with the ID information 227 held by the own apparatus, and, based on the comparison result, determines whether the disk It is determined whether to start (hard disk device 101), that is, whether to load a system program or the like.
[0070]
As a result, it is possible to authenticate in a short time whether or not the disk array device is valid without activating the hard disk device 101 in the cartridge device 100.
[0071]
For example, even in a case where a single cartridge device is mounted on an information processing device one by one in order to search for a proper cartridge device from a plurality of cartridge devices, a check can be performed without starting up the hard disk device in the cartridge device each time. Therefore, it is possible to quickly search for a proper cartridge device.
[0072]
[Second embodiment]
Next, a second embodiment, which is a partial improvement of the first embodiment, will be described focusing on points different from the first embodiment.
[0073]
In the first embodiment, when the ID information 225 held by the cartridge device 100 mounted on the information processing device 102 matches the ID information 227 held by the second control unit 208, authentication by the user is performed. The third control unit 209 (that is, the hard disk device 101) for realizing the main function without requesting it has been activated.
[0074]
In the second embodiment, even when the ID information 225 held by the cartridge device 100 and the ID information 227 held by the second control unit 208 match, the cover 103 of the cartridge device 100 is opened and closed in an offline state. If there is a possibility that the user has been authenticated, a user authentication for starting the third control unit 209 (hard disk device 101) is requested.
[0075]
FIG. 4 is a flowchart illustrating an operation when the second control unit 208 according to the second embodiment activates the third control unit.
[0076]
The difference from the flowchart of FIG. 3 according to the first embodiment is that the process of step S302 is replaced with the process of step S401, and that the process of step S402 is newly added after the affirmative determination in step S303. . Therefore, here, only step S401 and step S402 will be described, and description of other steps will be omitted.
[0077]
First, in step S401, the cover opening / closing history 226 is acquired from the first control unit 200 together with the ID information 225.
[0078]
In step S402, it is determined based on the cover opening / closing history 226 acquired in step S401 whether or not the cover 103 of the cartridge device 100 has been opened / closed in the offline state. If it is determined that the cover 103 has been opened / closed in the offline state, the process proceeds to step S402. Proceeding to S304, an authentication operation by the user is requested.
[0079]
If it is determined that the cover 103 of the cartridge device 100 has not been opened / closed, the process proceeds to step S307, and the power supply to the third control unit 209 is started to activate the third control unit 209.
[0080]
As described above, in the second embodiment, even if the ID information 225 and 227 match each other, if there is a trace that the cover 103 has been opened in the offline state, the contents are the contents of the cartridge device 100. Since it is determined that there is a possibility that the hard disk device 101 may have been handled illegally, an authentication operation by the user is requested, so that it is possible to more reliably prevent the information processing device 102 from operating by loading an unauthorized program or data. be able to.
[0081]
Since the possibility of improper handling of the hard disk device 101 is determined based on the opening / closing history of the cover 103 detected by the cover sensor 202, the configuration of the cartridge device 100 is simplified without complicating the configuration. Thus, it is possible to determine the possibility of improper handling of the hard disk device 101.
[0082]
Note that the present invention is not limited to the first and second embodiments described above, and various application modifications are possible.
[0083]
For example, in the first and second embodiments, whether or not the third control unit 209 may be activated, that is, whether the information stored in the hard disk device 101 can be loaded into the third control unit 209 The second control unit 208 different from the third control unit 209 that performs the activation (loading) performs the authentication process for determining whether or not the authentication process is performed.
[0084]
However, the process of loading the information stored in the hard disk device 101 into the third control unit 209 is executed by the BIOS program stored in the ROM 221 of the third control unit 209.
[0085]
Therefore, the BIOS processing of the third control unit 209 may execute the authentication processing executed by the second control unit 208. In this case, the process of acquiring the ID information 225 from the nonvolatile memory 204 of the first control unit 200 may be performed by either the first control unit 208 or the second control unit 209.
[0086]
Further, the second control unit 208 transmits the ID information 225 to the first control unit 200 without activating the third control unit 209 after successful authentication as in the first and second embodiments. After acquiring the ID information 225 from the nonvolatile memory 204 (when the second control unit 208 acquires the ID information 225) or immediately after the second control unit 208 is activated (the ID information 225 is acquired by the third control unit 209). If it is acquired, the third control unit 209 needs to be activated.
[0087]
Note that even when the third control unit 209 performs the authentication process, the third control unit 209 supplies power to the hard disk device 101 to start the hard disk device 101 only when the authentication is successful, and executes the system program and the like.
