[0001]

[Industrial applications]

 The present invention relates to a device for attaching a lid that is openably and closably attached to or detachable from a 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. The microarray has a detachable lid so that if the drive fails, the drive can be pulled out after removing the lid.

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]

[Problems to be solved by the device]

 As described above, the microarray has a detachable lid so that the drive can be pulled out. FIG. 13 is a diagram showing a device for attaching the lid 92 of the disk array S.

In FIG. 1, 89 is a cabinet of the disk array S, 90 is a front panel, and 91 is a microarray, and this microarray 91 is stored in the cabinet 89. The microarray 91 is fixed to a chassis (not shown).

On the front panel 90, engaging portions 90b that engage with stoppers 93 of a lid 92, which will be described later, are formed above and below the opening 90a. The front panel 90 is detachably attached to the cabinet 89. Reference numeral 92 denotes a lid, and a stopper 93 is formed on the lid 92 at a portion corresponding to the engaging portion 90b of the front panel 90. Then, as shown in FIG. 13, by fitting the lid 92 into the opening 90a of the front panel 90, the engaging portion 90b and the stopper 93 are engaged with each other and the lid 92 is mounted. Thereby, the lid 92 covers the front surface of the microarray 91.

By the way, in order to remove the lid 92 from the front panel 90, it is necessary to release the engagement between the stopper 93 of the lid 92 and the engaging portion 90b of the front panel 90 by removing the front panel 90 from the cabinet 89. There is. Therefore, it is difficult to remove the lid 92, and it takes time to repair or replace the drive.

Therefore, an object of the present invention is to facilitate opening / closing or attachment / detachment of a lid.
