BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper mechanism for a disk device or the like which is detachably mounted on an apparatus main body.

[0002]

2. Description of the Related Art A part of business performed on a conventional mainframe computer is now performed on a network of workstations and personal computers by downsizing the computer. Even in this case, the data storage device of the computer is required to have high speed and large capacity, and also to have high reliability and easy maintenance of the data as the importance of the data to be handled increases. Therefore, a technology of fault tolerance (fault tolerance) developed and used for a mainframe computer is indispensable for a personal computer and the like.

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

Therefore, there has been proposed a device (disk array) for disassembling and reorganizing data exchanged with a host computer by a dedicated disk controller and reading / writing data from / to a plurality of disk drives in parallel. by this,
Speeding up data processing, improving data reliability by writing parity information, and efficiently increasing storage capacity are achieved.

An intelligent array subsystem (IA) that extends the mainframe technology to the area of workstations and network file servers.
There has been proposed a microarray (microarray) having substantially the same function and performance as S) and having a size that can be mounted on a 5.25 inch drive base.

The microarray is provided with, for example, five drives (disk devices), stores data and parity information for error correction, and reconstructs data even if one drive fails. It is configured to be able to. That is, the microarray is configured to decompose data sent from the host into a certain length, generate parity, and record the information in each drive. Note that the microarray is configured to display when a drive fails, for example, by changing the emission color of a status lamp, and emit a warning sound.

In the microarray, an extension board on which an edge connector pattern of the drive is arranged is slotted into a socket of a relay board (drive backplane) to which the drive can be detachably inserted and electrically connected. It is configured so that it can be mounted. Note that both ends of the drive backplane are fixed to the microarray.

Accordingly, since the drive and the microarray are configured in a slot-in structure, when the drive fails and the drive is repaired, it is necessary to easily remove the failed drive even during the communication with the host and repair the drive. Can be. Then, when, for example, a reset operation is performed by mounting the repaired drive, the microarray starts reconstructing data stored in the drive before the repair or the like. Then, the reconstructed data is stored in the repaired drive. In this case, the process is performed in the background regardless of the host, so that the user can continue to access the data.

[0009]

By the way, as described above, the conventional microarray is configured such that the drive can be mounted by slotting the extension board of the drive into the socket portion of the drive backplane. . The mounting of the drive is locked only by pressing the extension board of the drive into the socket portion.

As a result, the stop position of the drive becomes unstable, and the connection between the extension board and the socket may become defective.

On the other hand, since both ends of the drive backplane are only fixed to the microarray, the drive backplane (relay board) is bent when the drive is mounted. This causes a problem of causing a problem.

Therefore, the present invention aims at positioning a disk device or the like with respect to the device main body to prevent, for example, a connection failure.

[0013]

According to the present invention, a board is provided on an apparatus main body into which a disk device or the like having an extension board is pushed in and mounted, and the board has a socket having a socket portion on a surface facing the extension board. In a stopper mechanism of a device or the like, a first mechanism for fixing a board to a device main body.
And a second stopper for restricting the insertion depth of the extension board with respect to the board fixed by the first stopper, on the side of the apparatus body that is closer to the end of the socket part. When the extension board is inserted into the socket portion, portions other than the extension board, such as a disk device, are brought into contact with the second stopper.

The present invention is characterized in that the first stopper holds the board and regulates the movement of the board when the disk device or the like is attached or detached.

[0015]

In the present invention, the disk device 2 is inserted into the cabinet 6 which is the main body of the device until the disk device 2 comes into contact with the stopper 42 as the second stopper. Thereby, the connection between the disk device 2 and the relay board (drive backplane) 50 is ensured. Even if the disk device 2 is pushed from the position of the stopper 42, the pushing is regulated by the stopper 42. Therefore, the pushing of the disk device 2 can be restricted by the stopper 42, and the disk device 2 can be stopped and positioned at a predetermined position of the cabinet 6. Therefore, for example, it is possible to prevent a load from being applied to the relay board 50 on which the electronic components for connecting the disk device 2 are arranged.

In the present invention, the position of the relay board 50 is regulated by the stopper 9 as the first stopper when the disk device 2 is mounted on the relay board 50 of the cabinet 6 which is the apparatus main body. It does not bend and is held in place. Accordingly, for example, the connection between the disk device 2 and the relay board is ensured, and the connection failure of the electronic components arranged on the relay board 50 due to the bending of the relay board 50 can be prevented.
