Detailed Description
Embodiments or examples of the display in the icons are expressed in a specific manner as follows. It should be understood that the embodiments or examples are not intended to be limiting. Any alterations and modifications in the described embodiments, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates.
Fig. 1 is a schematic diagram of a management system 100 of a PCIE device according to an embodiment of the invention. As shown in fig. 1, the PCIE device management system 100 includes a management host 110 and PCIE devices 120. The management host 110 includes a processing unit 112, an input unit 114, and a display unit 116, where the input unit 114 may be a keyboard, a mouse, and the like, and the display unit 116 may be a display screen. It should be understood that the input unit 114 and the display unit 116 are not limited to the management host 110, and may be external to the management host 110, or the functions of the input unit 114 and the display unit 116 may be implemented through a remote electronic device communicatively connected to the management host 110. The processing unit 112 is configured to execute the SAS user management program 112A, the conversion program 112B and the PCIE driver 112C, and it should be understood that data of the SAS user management program 112A, the conversion program 112B and the PCIE driver 112C may be stored in any storage unit (not shown) inside or outside the management host 110, and then loaded from the storage unit for execution when the processing unit 112 is to process the relevant program. In addition, the PCIE device 120 may be a storage device of a PCIE interface, for example, JBOD (Just a Bunch Of Disks), where the PCIE device 120 includes a processing unit 122 for executing a PCIE firmware 122A, and thereby communicates with the management host 110 for data transfer. Similarly, the data of the PCIE firmware 122A may be stored in any storage unit (not shown) inside or outside the PCIE device 120, and then loaded from the storage unit for execution when the processing unit 122 is to process the related program.
In some embodiments of the present invention, when a user at the host end wants to control the operation of the PCIE device 120 or obtain the status data of the PCIE device 120, the user selects the corresponding operation on the SAS user management program 112A through the input unit 114. For example, the SAS user manager 112A may have a plurality of control options corresponding to different operations (e.g., fan control, temperature data reading, display light control, firmware update, status reading, etc.). When the user selects the corresponding operation via the input unit 114, the input unit 114 generates the input signal SIN and transmits the input signal SIN to the processing unit 112, and the sas user management program 112A transmits the SCSI operation message MSCSI of the corresponding operation to the conversion program 112B according to the input signal SIN. It should be understood that the SCSI operation message MSCSI is in a format that can be recognized by the SCSI driver, and the SCSI driver can generate SCSI command data corresponding to the control SCSI interface device, whereas the SCSI operation message MSCSI cannot be recognized directly by the PCIE driver 112C.
In order for the PCIE driver 112C to interpret the control options selected by the user, the conversion process 112B generates a PCIE operation message MPCIE recognizable by the PCIE driver 112C according to the SCSI operation message MSCSI generated by the SAS user management process 112A. In other words, the conversion process 112B generates the PCIE operation message MPCIE indicated as the same control option according to the control option indicated by the SCSI operation message MSCSI, for example, converts the message format of the SCSI operation message MSCSI into the message format corresponding to the PCIE operation message MPCIE. In some embodiments of the present invention, the conversion process 112B includes conversion data, and the conversion data includes a plurality of corresponding SCSI operation messages and a plurality of PCIE operation messages, and the corresponding SCSI operation messages and PCIE operation messages indicate the same control options. Therefore, when the conversion program 112B receives the SCSI operation message MSCSI generated by the SAS user management program 112A, the conversion data is compared with the SCSI operation message to find out the corresponding PCIE operation message, and then the corresponding PCIE operation message is sent to the PCIE driver 112C.
When the PCIE driver 112C receives the PCIE operation message MPCIE, the PCIE command data DPCIE conforming to the PCIE interface format is transmitted to the processing unit 122 of the PCIE device 120 according to the PCIE operation message MPCIE. It should be appreciated that in some embodiments of the present invention, the conversion program 112B and the PCIE driver 112C may be integrated together as a modified PCIE driver, for example, the conversion program 112B of the present invention may be added to the PCIE driver 112C by a patch or update method, so that the modified PCIE driver may directly generate the corresponding PCIE command data DPCIE according to the SCSI operation message MSCSI generated by the SAS user management program 112A.
In some embodiments, when the processing unit 122 receives the PCIE command data DPCIE generated by the PCIE driver 112C, the PCIE firmware 122A executed by the processing unit 122 controls the PCIE device according to the PCIE command data DPCIE to complete the operation indicated by the PCIE command data DPCIE (i.e., the control option executed by the SAS user management program 112A) such as adjusting the fan speed on the PCIE device or lighting a specific light.
In other embodiments, if the control option indicated by the PCIE command data DPCIE is a data request, for example, reading temperature data, operation status, etc. on the PCIE device 120, the PCIE firmware 122A executed by the processing unit 122 generates PCIE response data DRPCIE conforming to the PCIE interface format according to the data requested by the PCIE command data DPCIE, and returns the PCIE response data DRPCIE to the processing unit 112 of the management host 110. Next, when the processing unit 112 receives the PCIE response data DRPCIE, the PCIE driver 112C transmits a PCIE response message MRPCIE to the conversion program 112B according to the PCIE response data DRPCIE. It should be appreciated that the PCIE response message MRPCIE is in a format recognizable by the PCIE subscriber manager but not directly recognizable by the SAS subscriber manager 112A. Therefore, in order for the SAS user management program 112A to recognize the data returned by the PCIE device 120, the conversion program 112B generates the SCSI response message mrcsi recognizable by the SAS user management program 112A according to the PCIE response message MRPCIE. In other words, the conversion program 112B generates the SCSI response message mrcsi indicated as the same data content according to the data content indicated by the PCIE response message MRPCIE, for example, converts the message format of the PCIE response message MRPCIE thereof into the corresponding message format of the SCSI response message mrcsi. In some embodiments of the present invention, the conversion process 112B includes conversion data, and the conversion data includes a correspondence between a plurality of PCIE response messages MRPCIE and a plurality of SCSI response messages mrcsi, and the corresponding PCIE response messages MRPCIE and SCSI response messages mrcsi indicate the same data content. Therefore, when the conversion program 112B receives the PCIE response message MRPCIE, the corresponding SCSI response message mrcsi is found by comparing the PCIE response message MRPCIE with the conversion data, and then the corresponding SCSI response message mrcsi is transmitted to the SAS user management program 112A. Finally, the SAS user management program 112A may transmit the output signal SOUT to the display unit 116 according to the data content indicated by the SCSI response message mrcsi, and the display unit 116 displays the frame corresponding to the data content indicated by the SCSI response message mrcsi according to the output signal SOUT for the user to view the relevant status of the PCIE device 120.
Fig. 2 is a schematic diagram of a management system 200 of a PCIE device according to another embodiment of the invention. As shown in fig. 2, the PCIE device management system 200 includes a management host 210 and PCIE devices 220. The management host 210 includes a processing unit 212, an input unit 214, and a display unit 216, where the input unit 214 may be a keyboard, a mouse, etc., and the display unit 216 may be a display screen. It should be understood that the input unit 214 and the display unit 216 are not limited to the management host 210, and may be external to the management host 210, or the functions of the input unit 214 and the display unit 216 may be implemented through a remote electronic device communicatively connected to the management host 210. The processing unit 212 is configured to execute the SAS user management program 212A and the SCSI driver 212C, and it should be understood that data of the SAS user management program 212A and the SCSI driver 212C may be stored in any storage unit (not shown) inside or outside the management host 210, and then loaded from the storage unit for execution when the processing unit 112 is to process the relevant program. In addition, the PCIE device 220 may be a storage device of a PCIE interface, for example, JBOD (Just a Bunch Of Disks), where the PCIE device 220 includes a processing unit 222 for executing a PCIE firmware 222A and a conversion procedure 222B. Similarly, the data of the PCIE firmware 222A and the conversion process 222B may be stored in any storage unit (not shown) inside or outside the PCIE device 220, and then loaded from the storage unit for execution when the processing unit 222 is to process the relevant process.
In some embodiments of the present invention, when a user at the host end wants to control the operation of the PCIE device 220 or obtain the status data of the PCIE device 220, the user selects the corresponding operation on the SAS user management program 212A through the input unit 214. For example, SAS user management program 212A may have a plurality of control options corresponding to different operations (e.g., fan control, temperature data reading, display light control, firmware update, status reading, etc.). When the user selects the corresponding operation via the input unit 214, the input unit 214 generates an input signal SIN accordingly and transmits the input signal SIN to the processing unit 212, and the sas user management program 212A transmits a SCSI operation message MSCSI of the corresponding operation to the SCSI driver 212C according to the input signal SIN.
When the SCSI driver 212C receives the SCSI operation message MSCSI, it transmits SCSI command data DSCSI conforming to the SCSI interface format to the processing unit 222 of the PCIE device 220 according to the SCSI operation message MSCSI. It should be understood that the SCSI command data dscis in a format that can be recognized by the SCSI firmware executed by the SCSI device, and the SCSI firmware can control the SCSI device according to the SCSI command data dscis, however, the SCSI driver 212C is configured to perform data transfer with the PCIE device 220, and the SCSI command data dscis used by the SCSI driver 212C cannot be recognized directly by the PCIE firmware 222A executed in the PCIE device 220.
In order for the PCIE firmware 222A to interpret the control option selected by the user, the conversion process 222B generates PCIE command data DPCIE recognizable by the PCIE firmware 222A according to the SCSI command data DSCSI. In other words, the conversion program 222B generates the PCIE command data DPCIE indicating the same command and conforming to the PCIE interface format according to the command indicated by the SCSI command data DSCSI, for example, converts the command format of the SCSI command data DSCSI thereof into the command format corresponding to the PCIE command data DPCIE. In some embodiments of the present invention, the conversion process 222B includes conversion data, and the conversion data includes a correspondence between a plurality of SCSI command data and a plurality of PCIE command data, and the corresponding SCSI command data and PCIE command data indicate the same command. Therefore, when the conversion program 222B receives the SCSI command data, the corresponding PCIE command data is found by comparing the SCSI command data with the conversion data, and then the corresponding PCIE command data is transferred to the PCIE firmware 222A.
It should be appreciated that in some embodiments of the present invention, the conversion process 222B and the PCIE firmware 222A may be integrated together as an improved PCIE firmware, for example, the conversion process 222B of the present invention may be added to the PCIE firmware 222A by a patch process or an update process, so that the improved PCIE firmware may directly control the PCIE device 220 according to the SCSI command data DSCSI generated by the SCSI driver 212C.
In other embodiments, if the instruction indicated by the PCIE instruction data DPCIE is a data request, for example, reading temperature data, operation status, etc. on the PCIE device 220, the PCIE firmware 222A executed by the processing unit 222 generates PCIE response data DRPCIE conforming to the PCIE interface format according to the data requested by the PCIE instruction data DPCIE, and converts the PCIE response data DRPCIE into SCSI response data DRSCSI conforming to the SCSI interface format through the conversion procedure 222B. It should be understood that the PCIE response data DRPCIE is in a format that can be directly recognized by the PCIE driver, but not directly recognized by the SCSI driver 212C. Therefore, in order for the SCSI driver 212C to recognize the data returned by the PCIE device 220, the conversion program 222B generates SCSI response data DRSCSI recognizable by the SCSI driver 212C according to the PCIE response data DRPCIE. In other words, the conversion process 222B generates the SCSI response data DRSCSI indicated as the same data content according to the data content indicated by the PCIE response data DRPCIE, for example, converts the message format of the PCIE response data DRPCIE thereof into the message format corresponding to the SCSI response data DRSCSI. In some embodiments of the present invention, the conversion process 222B includes conversion data, and the conversion data includes a corresponding relationship between a plurality of PCIE response data DRPCIE and a plurality of SCSI response data DRSCSI, and the corresponding PCIE response data DRPCIE and SCSI response data DRSCSI indicate the same data content. Therefore, when the conversion program 222B receives the PCIE response data DRPCIE, the corresponding SCSI response data DRSCSI is found by comparing the PCIE response data DRPCIE with the conversion data, and then the corresponding SCSI response data DRSCSI is transferred to the SCSI driver 212C.
Then, when the SCSI driver 212C receives the SCSI response data DRSCSI, the SCSI driver 212C transmits the SCSI response message mrcsi to the SAS user management program 212A according to the SCSI response data DRSCSI. Finally, the SAS user management program 212A may transmit the output signal SOUT to the display unit 216 according to the data content indicated by the SCSI response message mrcsi, and the display unit 216 displays the frame corresponding to the data content indicated by the SCSI response message mrcsi according to the output signal SOUT for the user to view the relevant status of the PCIE device 220.
In summary, through the setting of the conversion program of the present invention, the SAS user management program originally used for controlling the SCSI device in the management host can be extended to be used for controlling and managing the PCIE device, so that the conversion cost and the re-adaptation time of the user in the related management software are greatly reduced, and the control and management of the management host in different interface devices are more flexible.
