2 is a block diagram showing a storage management and backup solution system of an industrial computer according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a data converter 100 according to the present invention includes a plurality of connectors 11, 13, 15, and 17 for interfacing heterogeneous hard disks 210, 220, A SATA conversion board 30 mounted on the main board 10, an MCP 70 connected to the SATA conversion board 30, a RAID controller 50 and a hot swap controller 90 .

The main board 10 is provided with a SCSI connector 11, an IDE connector 13, and two SATA connectors 15.

Here, the SCSI hard disk 210 is connected to the SCSI connector 11 during data conversion or copying, the IDE hard disk 220 is connected to the IDE connector 13, and the SATA hard disk 230 is connected to the first SATA connector (Not shown).

The second SATA connector 17 is a connection terminal provided to connect the data converted by the SATA conversion board 30 to another SATA hard disk or SSD for copying and backing up.

The SATA conversion board 30 is a conversion board for converting data received from the SCSI, IDE and SATA hard disks 210, 220 and 230 into the SATA system. It should be noted that data received from the SATA hard disk 230 does not undergo any conversion.

The RAID controller 50 receives and converts the SATA data converted by the SATA conversion board 30 to a plurality of SATA hard disks or SATA SSDs 240 and 250. Here, the RAID controller 50 can copy and back up SATA data regardless of whether the recording medium is a hard disk or an SSD. However, the recording medium is constrained to a limiting element called SATA system. Particularly, this limiting factor is determined because the raid controller 50 receives the converted SATA data from the SATA conversion board 30.

When the recording medium to be copied and backed up by the RAID controller 50 is a hard disk, it is preferably a hard disk having the same capacity of the SATA system and an SSD having the same capacity of the SATA system when the recording medium is an SSD Do.

The MCP 70 is a microprocessor and recognizes the main hard disk (or SSD) and the sub hard disk (or SSD) separately from the hard disk or the SSD 240 (250) as a recording medium.

When an error occurs in the main hard disk or the SSD 240, the hot swap controller 90 recognizes the sub hard disk or the SSD 250 as a main unit, and can replace the failed hard disk or the SSD without powering off do.

It is most preferable that the RAID controller 50, the MCP 70 and the hot swap controller 90 are mounted on one board and is connected to the second SATA connector 17 of the main board 10, A connector connected to the second SATA connector 17 and a connector connected to a plurality of HDDs or SSDs are not shown. The RAID controller 50, the MCP 70, and the hot swap controller 90 must be interconnected.

In all of the following embodiments, it is made clear in advance that a SATA type hard disk or SSD to be copied and backed up is mounted in advance.

1. Copy and back up data from the SCSI hard disk (210) to the SATA hard disk or SSD

The SCSI hard disk 210 to be copied is connected to the SCSI connector 11.

Then, the SATA conversion board 30 converts the data stored in the SCSI hard disk 210 into the SATA format according to a pre-installed program.

The converted SATA data is then copied and backed up to the hard disk or SSD 240 (250) to be copied and backed up.

If an error occurs in the main hard disk or the SSD 240, the hot swap controller 90 automatically recognizes the sub hard disk or the SSD 250 as main, 240 and then executes the copying and backup of the data of the SCSI type hard disk 210 to the SATA type hard disk or the SSD 240 or SAT 250 by the SATA method.

2. Copy and backup data from IDE hard disk (220) to SATA hard disk or SSD

The IDE hard disk 220 to be copied is connected to the IED connector 13.

Then, the SATA conversion board 30 converts the data stored in the IDE hard disk 220 into the SATA format according to a pre-installed program.

The converted SATA data is then copied and backed up to the hard disk or SSD 240 (250) to be copied and backed up.

If an error occurs in the main hard disk or the SSD 240, the hot swap controller 90 automatically recognizes the sub hard disk or the SSD 250 as main, 240, and then executes the data copy and backup of the data of the IDE type hard disk 220 to the SATA type hard disk or the SSD 240 (250) by the SATA method.

3. When copying and backing up the data of the SATA hard disk (230) to the SATA hard disk or SSD

The SATA hard disk 230 to be copied is connected to the IED connector 13. [

Then, the SATA conversion board 30 transmits data stored in the SATA hard disk 230 without any conversion, and is copied and backed up to the hard disk or SSD 240 (250) to be copied and backed up.

If an error occurs in the main hard disk or the SSD 240, the hot swap controller 90 automatically recognizes the sub hard disk or the SSD 250 as main, 240), then copy and backup will be completed.

4. When copying and backing up data of SCSI, IDE, SATA hard disks 210, 220 and 230 to the SATA hard disk or SSD

In this case, since the SATA conversion board 30 is the same as the other embodiments except that the data is converted in a predetermined order by a pre-installed program, a detailed description thereof will be omitted.

The program of the SATA conversion board 30 of the present invention can convert data by the following method.

① Converts all SCSI, IDE and SATA hard disks to SATA format

② In case ① above, at least one specific hard disk selected regardless of the data format is converted into SATA data

In this case, in selecting at least one hard disk,

Regardless of the model of the hard disk, only the specific hard disk can be selected for data conversion, and only the hard disk of the same data format can be selected and converted.

It should be noted that the embodiment of the present invention has been shown and described as being limited to only one sub-hard disk or SSD, but is not limited thereto.

The configuration of the present invention is shown as being separated from the main board 10, the SATA conversion board 30 and the RAID controller 50 / MCP 70 / hot swap controller 90, And it is preferable that all of these components are mounted on one board.

2, the storage management and backup solution system of the industrial computer according to the present invention includes a main hard disk 310, a data converter 100, a return hard disk 320, a storage controller 400, (330) and (340).

The main hard disk 310 is a main hard disk mounted on an industrial computer. Here, the main hard disk 310 is any one of IDE, SCSI, and SATA hard disks.

As described above, the data converter 100 according to the present invention can store all data stored in the main hard disk 310 in a predetermined time or in real time even if the type of the main hard disk 310 is IDE, SCSI, or SATA And simultaneously stores the operating system in the SATA type return hard disk 320.

In addition, the storage controller 400 according to the present invention compresses a selected portion or all of the data stored in the returning hard disk 320 within a time determined by the loaded program, and simultaneously copies the data to the backup hard disk 330 (340) .

Here, the backup hard disks 330 and 340 are physically two hard disks, but are recognized as one hard disk by the storage controller 400 that supports mirroring, and backup is simultaneously performed.

The system of the present invention as described above can copy data and operating system to the return hard disk at the same time regardless of the type of the main hard disk installed in the industrial computer and selectively restore the data of the return hard disk by the storage controller So that even if an error occurs in the main hard disk, the hard disk is operated in real time without interrupting or applying the power, so that the return of the industrial line can be accomplished quickly.

In addition, the configuration of the present invention is advantageous in that stable data management can be implemented by backing up selected part or all of the data of the returning hard disk.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
