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 drive, a connector board as a connection member is fixed to a main body of the drive with a bolt or the like as a fastening member. Then, the microarray has a slot provided on the extension board on which the edge connector pattern of the connector board of the drive is arranged in a socket, which is a connecting portion 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 by inserting it.

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]

As described above, the conventional microarray can be mounted by slot-in the extension board of the drive (disk device) into the socket of the drive backplane (relay board). Is configured. FIG. 8 shows a conventional slot-in configuration.
