[Industrial applications]

 The present invention relates to a locking device such as a disk device detachably arranged in the device body.

[0002]

[Prior art]

 By downsizing computers, some of the work that was done with conventional mainframe computers is now done with workstations and personal computer networks. Even in this case, the data storage device of the computer is required to have high speed and large capacity, and as the importance of the data to be handled increases, the reliability of the data and the ease of maintenance are required. It Therefore, fault tolerance technology developed and used for mainframe computers is essential for personal computers and the like.

As a data fault tolerance data storage of a mainframe computer which has been conventionally used, there is a method of writing the same data in parallel by using two drives. However, with this method, it is necessary to prepare a disk capacity that is twice the required capacity, and to stop the system when replacing a failed disk. Moreover, its processing speed cannot be faster than the speed of a single drive.

Therefore, a device (disk array) has been proposed in which data to be exchanged with a host computer is disassembled and reorganized by a dedicated disk controller to read / write in parallel to a plurality of disk drives. As a result, the speed of data processing can be increased, the reliability of data can be improved by writing the parity information, and the storage capacity can be efficiently increased.

In addition, the mainframe technology has been expanded to the area of workstations and network file servers, and it has almost the same functions and performance as an intelligent array subsystem (IAS), and is mounted on a 5.25-inch drive base. A miniaturized one (microarray) has been proposed.

[0006] For example, five drives (disk devices) are arranged in this microarray, and data and parity information for error correction are stored in this drive, and even if one drive fails, the data is regenerated. It is configured to be built. In other words, the microarray is configured to decompose the data sent from the host into fixed lengths, generate parities, and record this information in each drive. When the drive fails, the microarray is configured to display, for example, by changing the emission color of the status lamp and emit a warning sound.

In addition, in the microarray, the extension board on which the edge connector pattern of the drive is arranged is slot-in into the socket portion of the relay board (drive backplane) to which the drive is detachably and electrically connected. It is configured to be installed by.

Therefore, since the drive and the microarray have a slot-in structure, when the drive fails and the drive is repaired, the failed drive can be easily removed even during the communication with the host. can do. Then, when the repaired drive is mounted and the reset operation is performed, the microarray starts rebuilding the data stored in the drive before the repair. Then, the reconstructed data is stored in the repaired drive. The process in this case happens in the background, independent of the host, so the user can continue to access the data.

[0009]

By the way, as described above, the conventional microarray is configured so that it can be mounted by slotting the extension board of the drive into the socket portion of the drive backplane. . In other words, the drive is locked by simply pressing the drive extension board into the socket. Therefore, a normal disk device may be removed without checking beforehand.

Therefore, an object of the present invention is to prevent accidental removal of a disk device or the like from the device body.

[0011]

[Means for Solving the Problems]

 In this invention, the disk device is removably arranged in the main body of the apparatus, and the locking means for engaging and positioning the disk device with the main body of the apparatus is provided. Only when the locking means is released, It is configured so that it can be removed from the main unit.

As shown in FIG. 4, the button 23 is formed with locking portions 25 on its upper and left sides for preventing the button from coming off. As shown in FIG. 6, the locking portion 25 is always fitted in the hole 2a of the disk device 2. Therefore, the button 23 is restricted in the moving direction (vertical direction) with respect to the disk device 2 by the locking portion 25.

The locking piece 24 is formed by bending a leaf spring. The locking piece 24 has one end fixed to the button 23 by a rivet 26, as shown in FIG. 6A. Further, as shown in FIGS. 4B and 6, the locking piece 24 has its other end fixed to the lower surface of the disk device 2 with a screw 27. The button 23 is configured to be urged downward by the spring force of the locking piece 24 when the button 23 is operated and positioned above.

The disk device 2 has a connector board 30 connected to a drive board (not shown) on one side thereof (see FIG. 4A). An extension board 31 on which an edge connector pattern (not shown) is arranged is formed on the connector board 30. The extension board 31 can be slotted into a socket portion 51 of a relay board (drive back plane) 50 described later.

In the cabinet 6, as shown in FIG. 5, five rails 40 are arranged in parallel at portions corresponding to the guide portions 20 of each disk device 2. The rail 40 has an engagement hole 41 formed on the front side thereof so as to engage with the locking piece 24 of the stopper 22 of the disk device 2. The engagement hole 41 that constitutes this locking means is set so that both ends of the locking piece 24 do not collide with the rail 40 when the disk device 2 is housed in the cabinet 6, as shown in FIG. 6B. Has been done.

In FIG. 5, reference numeral 50 denotes a drive back plane, and the socket portion 51 of the drive back plane 50 is arranged so as to correspond to the extension board 31 of the disk device 2. The drive backplane 50, the memory / EDC board 52, and the CPU board 53 are connected to the array backplane 54, respectively.

As shown in FIG. 5, the cabinet 6 is formed with a stopper 42 at the rear side of the rail 40 for positioning the insertion position of the disk device 2. In addition, the cabinet 6 is provided with support portions 43 for mounting the lid 4 on the front left and right lower sides thereof.

Further, an upper panel 44 that constitutes a mounting body is mounted above the cabinet 6. Further, as shown in FIG. 5, the upper panel 44 is provided with a support portion 45 for fixing an engagement pin (not shown) of the lid 4 at one end thereof. Then, the engagement pin of the lid 4 is engaged with the cabinet 6 and the support portions 43 and 45 of the upper panel 44, so that the lid 4 is mounted on the cabinet 6. The drive backplane 50 is fixed to the other end of the upper panel 44.

When the microarray 1 is powered on and started up, only the status lamp R 2 of the display unit 3 lights up in red. When the disk array S rises and enters a steady state, the status lamp R2 changes from red to green. In the communication state between the host computer and the disk array, the status lamp R2 lights in green and the access lamp R1 lights in orange.

When the disk device 2 fails, the access lamp R1 is turned off and the status lamp R2 changes from green to red. In this case, the disk array S 2 also emits a warning sound, for example. Then, the user recognizes that the disk device 2 in which the color of the status lamp R2 has changed to red has failed, and repairs or replaces the disk device 2.

To remove the defective disk device 2 from the cabinet 6, for example, the reset button R3 is pressed. As a result, the removal of the disk device 2 is transmitted to the disk array S. Then, the failed disk device 2 is removed from the cabinet 6 and repaired.

The disk device 2 that has been repaired or the like is inserted into the removed portion. After that, when the reset button R3 of the inserted disk device 2 is pressed, only the status lamp R2 lights up in red as when the power source was turned on. After that, the access lamp R1 and the status lamp R2 are turned on in response to the same operation as described above.

To mount the disk device 2 on the rail 40 of the cabinet 6, the guide portion 20 of the disk device 2 is inserted along the rail 40. Then, as shown in FIG. 6A, the locking piece 24 of the stopper 22 comes into contact with the front side of the rail 40, so that the locking piece 24 moves upward. Therefore, the button 23 moves upward as the locking piece 24 moves. In this state, the spring force of the locking piece 24 acts to urge the button 23 downward.

Further, when the disk device 2 is inserted until it abuts on the stopper 42 (see FIG. 5) of the cabinet 6, as shown in FIG. 6B, the locking piece 24 engages with the engagement hole 41. The stop piece 24 moves downward due to its urging force. Therefore, the locking piece 24 and the front side of the engagement hole 41 of the rail 40 are held in a state of being opposed to each other, so that the disk device 2 can be held unless the engagement of the locking piece 24 and the engagement hole 41 is released. Cannot be removed by cabinet 6. The button 23 moves downward with the movement of the locking piece 24. Further, in this state, the extension board 31 of the disk device 2 and the socket portion 51 of the drive backplane 50 are connected.

To remove the disk device 2 whose status lamp R 2 has changed from green to red due to a failure from the cabinet 6, the button 23 in the state of FIG. 6B is moved upward. As a result, the state in which the locking piece 24 and the front side of the engagement hole 41 of the rail 40 do not face each other, that is, the engagement between the locking piece 24 and the engagement hole 41 is released. When the disk device 2 is moved to the front side in this state, the disk device 2 can be removed from the cabinet 6 through the state shown in FIG. 6A.

According to this example, the disk device 2 is positioned by the engagement of the locking piece 24 and the engagement hole 41, and the extension board 31 of the disk device 2 and the socket portion 51 of the drive backplane 50 are connected. Can be reliably performed.

Further, according to this example, the disk device 2 can be removed from the cabinet 6 by releasing the engagement between the locking piece 24 and the engagement hole 41. Therefore, according to this example, since the engagement between the locking piece 24 and the engagement hole 41 needs to be released in order to remove the disk device 2 from the cabinet 6, the disk device 2 is mistakenly removed from the cabinet 6. Can be prevented and the safety of its removal can be secured.

FIG. 7 is a block diagram of the microarray 1 of the embodiment. In the figure, 90 is a SCSI controller of the microarray 1. Then, when the S CSI controller 90 is connected to the SCSI adapter 92A of the host system 92 via the SCSI bus 91, the information of the host system 92 is passed through the array backplane 54 to the CPU board 53, the memory / EDC board 52, and the drive bus. Stored in the disk of the disk device (drive) 2 via the backup plane 50.

The shapes and structures of the stopper 22 of the disk device 2 and the rail 40 of the cabinet 6 are not limited to those in the above-described embodiments, but the same can be applied if the disk device can be locked in the cabinet.

Further, a lamp indicating that the engagement between the locking piece 24 and the engagement hole 41 is released may be arranged on the display portion 3 of the disc device 2. Then, this lamp can further ensure the safety of the removal of the disk device 2. Further, when the normal locking means of the disk device 2 is disengaged by mistake, a warning sound may be emitted.

Further, in the above-described embodiment, the example applied to the disk device is shown, but this idea can be applied to a recording / reproducing device using a tape or the like as a recording medium.
