Description

  The present invention relates to a data processing relay device. In particular, the present invention relates to a data processing relay device that relays data processing from a server device to an external storage device of a client device.

  An enterprise server is equipped with a control board called a management board. If the management board firmware supports the virtual KVM (Keyboard, Video, Mouse) function, the server administrator can operate the server keyboard, video, and mouse from a remote environment. Therefore, the server administrator can operate and maintain the server without going to the server installation location.

  A known management board allows a server OS to directly display a removable media file system connected to a console. In this way, the OS of the server can use the removable media connected to the console as if it were directly connected to the server.

  However, depending on the known management board, the virtual KVM function cannot be used unless the file system supported by the server OS and the file system supported by the console are the same. That is, depending on a known management board, a legacy device that is not supported by the server OS cannot be used by the virtual KVM function. In addition, the writing speed of the server OS to the USB device by the virtual KVM function is slow.

  By the way, as a method of reading from or writing to a drive device and a record carrier such as an optical disc, a technique related to format mapping from a standard drive interface to an optical disc format is known (see, for example, Patent Document 1). .)

  However, the technique described in Patent Document 1 is a technique for maintaining compatibility of an interface connected to hardware. Therefore, the OS that controls the drive device needs to support both the recording medium and the interface. Therefore, depending on the technique described in Patent Document 1, even if hardware compatibility is maintained, the burden of software support cannot be reduced.

  In order to solve the above problem, according to the first aspect of the present invention, there is provided a data processing relay device that relays data processing from a server device to an external storage device of a client device, the operation of the data processing relay device being Storage means comprising control means for controlling, a first partition of the same file system as the file system of the external storage device of the server device, and a second partition of the same file system as the file system of the external storage device of the client device And the control means includes a data input acceptance unit that accepts input of data output from either the server device or the client device, and a data input acceptance unit of the two partitions that the storage means comprises The file system of the external storage device from which the data received by the Data copy unit that writes data received by the data input reception unit to the partition of the same file system and data of the write destination partition written by the data write unit to the other partition And a data output unit that outputs the data of the copy destination partition copied by the data copy unit to the same file system device as the copy destination partition of the external storage device of either the server device or the client device. Have.

  In addition, as described above, the summary of the invention does not enumerate all necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  As is apparent from the above description, in the present invention, input of data output from the external storage device of either the server device or the client device is accepted, and the input of the two partitions included in the storage means is input. Write the input data to a partition of the same file system as the file system of the external storage device that is the source of the received data, copy the data of the destination partition to the other partition, and The partition data is output to a device of the same file system as that of the copy destination partition in either the server device or the client device. In this way, in the present invention, for example, by using the virtual KVM function of firmware, it is possible to use an external storage device of a client device having a file system that is not supported by the OS of the server device.

The function and operation of each component will be described below.

  The OS discriminating unit 111 discriminates what OS the server 200 and the console 300 are. Then, the OS determination unit 111 sends data indicating the determination result to the partition generation unit 112.

  When the partition generation unit 112 receives the data indicating the determination result from the OS determination unit 111, the partition generation unit 112 generates a partition in the microSD memory card 120 so that the file system can be used by the OS of the server 200 indicated by the determination result data. . Further, the partition generation unit 112 generates a partition in the microSD memory card 120 so that the file system can be used by the OS of the console 300 indicated by the determination result data received from the OS determination unit 111.

  The command receiving unit 113 receives a data processing command from the server 200 to the console 300. Then, the command receiving unit 113 sends data indicating the received command to the data input receiving unit 114.

  The data input accepting unit 114 accepts input of data output from either the server 200 or the console 300 external storage device. Then, the data input unit 114 sends the received data to the data writing unit 115. More specifically, the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the USB memory 310 and write it to the external storage device of the server 200. In this case, the data input receiving unit 114 receives an input of data output from the console 300. If the content of the command received from the server 200 received by the command receiving unit 113 is a command to read data stored in the external storage device of the server 200 and write it to the USB memory 310, the data input is accepted. Unit 114 accepts input of data output from server 200.

  When the data writing unit 115 receives the data from the data input receiving unit 114, the data writing unit 115 includes the file system of the external storage device from which the data input receiving unit 114 receives the input of the VxFS area 121 and the FAT area 122. The data received by the data input receiving unit 114 is written into the partition of the same file system. More specifically, the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the USB memory 310 and write it to the external storage device of the server 200. In this case, the data writing unit 115 writes the data received by the data input receiving unit 114 in the FAT area 122. If the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the external storage device of the server 200 and write it to the USB memory 310, data write The unit 115 writes the data received by the data input receiving unit 114 in the VxFS area 121.

  The data copying unit 116 copies the data of the write destination partition written by the data writing unit 115 to the other partition. More specifically, the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the USB memory 310 and write it to the external storage device of the server 200. In this case, the data copying unit 116 copies the data in the FAT area 122 written by the data writing unit 115 to the VxFS area 121. Further, when the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the external storage device of the server 200 and write it to the USB memory 310, the data copying unit 116 copies the data in the VxFS area 121 written by the data writing unit 115 to the FAT area 122.

  The data output unit 117 outputs the data of the copy destination partition copied by the data copy unit 116 to a device of the same file system as the copy destination partition in either the external storage device of the server 200 or the console 300. More specifically, the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the USB memory 310 and write it to the external storage device of the server 200. In this case, the data output unit 117 outputs the data in the VxFS area 121 copied by the data copying unit 116 to the server 200. If the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the external storage device of the server 200 and write it to the USB memory 310, a data output unit 117 outputs the data in the FAT area 122 copied by the data copying unit 116 to the console 300.

  The response output unit 118 outputs a response to the command received from the server 200 by the command receiving unit 113 to the server 200. More specifically, the content of the command from the server 200 received by the command receiving unit 113 is a command to read data stored in the external storage device of the server 200 and write it to the USB memory 310. In this case, the response output unit 118 writes the data received by the data input receiving unit 114 into the VxFS area 121 by the data writing unit 115 and then the data copying unit 116 transfers the data in the VxFA area 121 to the FAT area 122. Before copying, the command receiving unit 113 outputs a response to the command received from the server 200 to the server 200.

  FIG. 3 shows an example of the operation flow of the service processor 110. When the OS of the server 200 starts reading processing for a USB device constructed by the firmware, the command receiving unit 113 of the service processor 110 receives an input of a reading command for the USB memory 310 (S101).

  Then, the data input accepting unit 114 of the service processor 110 makes a read request to the USB memory 310 connected to the console via the network in order to respond to the read contents of the USB memory 310 to the OS of the server. (S102), the data read from the USB memory 310 connected to the console 300 is received through the communication line 400 (S103).

  The file system of the USB memory 310 connected to the console 300 is in the FAT format. Therefore, the data writing unit 115 of the service processor 110 writes the read data of the USB memory 310 connected to the console 300 into the FAT area 122 constructed on the microSD memory card 120 (S104).

  When the FAT area 122 is updated, the data copying unit 116 of the service processor 110 also updates the VxFS area 121 (S105). In this way, the read data can be returned in a format that can be recognized by the OS of the server 200.

  After the update of the VxFS area 121 is completed, the data output unit 117 of the service processor 110 returns the read data of the VxFS area 121 to the OS of the server 200 (S106).

  FIG. 4 shows another example of the operation flow of the service processor 110. When the OS of the server 200 starts writing processing for the USB device constructed by the firmware, the data input receiving unit 114 of the service processor 110 receives an input of a writing command to the USB memory 310 (S201).

  When receiving the write data from the OS of the server 200, the data writing unit 115 of the service processor 110 updates the VxFS area 121 (S202).

  In order to prevent the OS 200 writing process of the server 200 from waiting for a long time, the response output unit 118 of the service processor 110 immediately updates the writing data from the OS of the server 200 to the VxFS area 121 and then immediately updates the OS of the server 200. A write completion notification is issued (S203).

  When the VxFS area 121 is updated, the data copying unit 116 of the service processor 110 also updates the FAT area 122 (S204).

  Then, after completing the update of the FAT area 122, the data output unit 117 of the service processor 110 transmits the write data to the USB memory 310 of the console 300 via the network (S205).

  FIG. 5 shows still another example of the operation flow of the service processor 110. When the OS of the server 200 starts the medium initialization process for the USB memory 310 constructed by the firmware, the data input accepting unit 114 of the service processor 110 accepts the input of the initialization command for the USB memory 310 (S301). .

  When receiving a medium initialization command from the OS of the server 200, the data writing unit 115 of the service processor 110 initializes the VxFS area 121 (S302).

  Then, the data copying unit 116 of the service processor 110 initializes the FAT area 122 (S303).

  Then, the data output unit 117 of the service processor 110 transmits a medium initialization command to the console 300, and initializes the USB memory 310 of the console 300 (S304).

  As described above, depending on the server 200 using the management board 100, the USB memory 310 of the console 300 having a file system that is not supported by the OS of the server 200 may be used by using the virtual KVM function of the firmware. Will be able to.

  In addition, the management board 100 immediately returns the contents written from the OS to the OS after updating the VxFS area 121 on the microSD card 120. Therefore, depending on the server 200 using the management board 100, it is possible to speed up the writing process for the USB device constructed by the management board 100 from the OS.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
