[ detailed description ] embodiments
The embodiments or examples shown in the figures are expressed in a particular manner as set forth below. It is to be understood that the embodiment or examples are not to be construed as 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 illustrating a management system 100 of a PCIE device according to an embodiment of the present invention. As shown in fig. 1, a 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 input unit 114 and the display unit 116 may be implemented by a remote electronic device communicatively connected to the management host 110. The processing unit 112 is configured to execute the SAS user manager 112A, the converter 112B and the PCIE driver 112C, and it should be understood that the data of the SAS user manager 112A, the converter 112B and the PCIE driver 112C can be stored in any storage unit (not shown) inside or outside the management host 110, and when the processing unit 112 needs to process the related programs, the data is loaded from the storage unit and then executed. Moreover, the PCIE device 120 may be a storage device Of a PCIE interface, for example, jbod (just a bus Of disks), and the PCIE device 120 includes a processing unit 122 for executing a PCIE firmware 122A, and thereby communicating with the management host 110 for data transmission. Similarly, the data of the PCIE firmware 122A can be stored in any storage unit (not shown) inside or outside the PCIE device 120, and when the processing unit 122 needs to process the related processes, the data is loaded from the storage unit and then executed.
In some embodiments of the present invention, when a user at the management host wants to control the operation of the PCIE device 120 or obtain status data of the PCIE device 120, the user selects a corresponding operation on the SAS user management program 112A through the input unit 114. For example, the SAS customer manager 112A may have a plurality of control options corresponding to different operations (e.g., fan control, temperature data reading, display lamp control, firmware update, status reading, etc.). When the user selects the corresponding operation through the input unit 114, the input unit 114 correspondingly generates the input signal SIN to be transmitted 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 appreciated 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, however, the SCSI operation message MSCSI cannot be directly recognized by the PCIE driver 112C.
In order to enable the PCIE driver 112C to interpret the control option selected by the user, the converter 112B generates the PCIE operation message MPCIE that can be recognized by the PCIE driver 112C according to the SCSI operation message MSCSI generated by the SAS user manager 112A. In other words, the conversion program 112B generates the PCIE operation message mpice 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 mpice. In some embodiments of the present invention, the conversion procedure 112B includes conversion data, and the conversion data includes a corresponding relationship between a plurality of 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. Thus, when the conversion program 112B receives the SCSI operation message MSCSI generated by the SAS user management program 112A, the corresponding PCIE operation message is found by comparing the SCSI operation message with the conversion data, and then the corresponding PCIE operation message is transmitted to the PCIE driver 112C.
When the PCIE driver 112C receives the PCIE operation message MPCIE, it transmits PCIE command data DPCIE conforming to the PCIE interface format 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 converter 112B and the PCIE driver 112C may be integrated together as an improved PCIE driver, for example, the converter 112B of the present invention may be added to the PCIE driver 112C by a patch or an update method, so that the improved PCIE driver can directly generate the corresponding PCIE command data DPCIE according to the SCSI operation message MSCSI generated by the SAS user manager 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 user on the SAS user manager 112A), for example, adjusting the fan speed on the PCIE device or lighting a specific light number.
In other embodiments, if the control option indicated by the PCIE command data DPCIE is a data request, for example, reading temperature data and operating status 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 transmits the PCIE response data DRPCIE back to the processing unit 112 of the management host 110. Then, 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 that can be recognized by the PCIE user manager, but cannot be recognized directly by the SAS user manager 112A. Therefore, in order to make the SAS subscriber manager 112A recognize the data returned by the PCIE device 120, the conversion program 112B generates a SCSI response message MRSCSI that is recognized by the SAS subscriber manager 112A according to the PCIE response message MRPCIE. In other words, the conversion program 112B generates the SCSI response message MRSCSI 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 its PCIE response message MRPCIE into the message format corresponding to the SCSI response message MRSCSI. In some embodiments of the present invention, the conversion program 112B includes conversion data, and the conversion data includes a corresponding relationship between a plurality of PCIE response messages MRPCIE and a plurality of SCSI response messages MRSCSI, and the corresponding PCIE response messages MRPCIE and SCSI response messages MRSCSI indicate the same data content. Therefore, when the conversion program 112B receives the PCIE response message MRPCIE, the corresponding SCSI response message MRSCSI is found by comparing the PCIE response message MRPCIE with the conversion data, and then the corresponding SCSI response message MRSCSI is transmitted to the SAS user management program 112A. Finally, the SAS ue 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 MRSCSI, and the display unit 116 displays a screen corresponding to the data content indicated by the SCSI response message MRSCSI according to the output signal SOUT for the user to view the related status of the PCIE device 120.
Fig. 2 is a diagram illustrating a management system 200 of a PCIE device according to another embodiment of the present invention. As shown in fig. 2, PCIE device management system 200 includes management host 210 and PCIE device 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, and the like, 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 externally connected to the management host 210, or the input unit 214 and the display unit 216 may be implemented by a remote electronic device communicatively connected to the management host 210. The processing unit 212 is configured to execute the SAS user manager 212A and the SCSI driver 212C, and it should be understood that data of the SAS user manager 212A and the SCSI driver 212C may be stored in any storage unit (not shown) inside or outside the management host 210, and when the processing unit 112 needs to process a relevant program, the data is loaded from the storage unit and then executed. Moreover, the PCIE device 220 may be a storage device Of a PCIE interface, for example, jbod (just a bus Of disks), and the PCIE device 220 includes a processing unit 222 for executing a PCIE firmware 222A and a conversion program 222B. Similarly, the data of the PCIE firmware 222A and the conversion program 222B can be stored in any storage unit (not shown) inside or outside the PCIE device 220, and when the processing unit 222 needs to process the related programs, the data is loaded from the storage unit and then executed.
In some embodiments of the present invention, when a user at the management host wants to control the operation of the PCIE device 220 or obtain status data of the PCIE device 220, the user selects a corresponding operation on the SAS user management program 212A through the input unit 214. For example, the SAS customer manager 212A may have a plurality of control options corresponding to different operations (e.g., fan control, temperature data reading, display lamp control, firmware update, status reading, etc.). When the user selects the corresponding operation through the input unit 214, the input unit 214 correspondingly generates the input signal SIN to be transmitted to the processing unit 212, and the SAS user manager 212A transmits the 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 sends SCSI command data DSCSI compliant with the SCSI interface format to the processing unit 222 of the PCIE device 220 according to the SCSI operation message MSCSI. It should be appreciated that the SCSI command data DSCSI is 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 DSCSI, however, the SCSI command data DSCSI used by the SCSI driver 212C is not directly recognized by the PCIE firmware 222A executed in the PCIE device 220.
In order to allow the PCIE firmware 222A to interpret the control option selected by the user, the conversion program 222B generates PCIE command data DPCIE that the PCIE firmware 222A can recognize according to the SCSI command data DSCSI. In other words, the conversion program 222B generates 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 into the command format corresponding to the PCIE command data DPCIE. In some embodiments of the present invention, the conversion program 222B includes conversion data, and the conversion data includes a corresponding relationship 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. Thus, when the conversion program 222B receives the SCSI command data, it finds out the corresponding PCIE command data by comparing the SCSI command data with the conversion data, and then transmits the corresponding PCIE command data to the PCIE firmware 222A.
It should be appreciated that in some embodiments of the present invention, the conversion program 222B and the PCIE firmware 222A may be integrated together as a modified PCIE firmware, for example, the conversion program 222B of the present invention may be added to the PCIE firmware 222A by a patch or update process, so that the modified PCIE firmware can directly control the PCIE device 220 according to the SCSI command data DSCSI generated by the SCSI driver 212C.
In other embodiments, if the command indicated by the PCIE command data DPCIE is a data request, for example, reading temperature data and operating status 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 command data DPCIE, and converts the PCIE response data DRPCIE into SCSI response data DRSCSI conforming to the SCSI interface format through the conversion program 222B. It should be appreciated that the PCIE response data DRPCIE is in a format that can be directly recognized by the PCIE driver, but cannot be directly recognized by the SCSI driver 212C. Therefore, in order to make the SCSI driver 212C recognize the data returned by the PCIE device 220, the conversion program 222B generates SCSI response data DRSCSI that is recognized by the SCSI driver 212C according to the PCIE response data DRPCIE. In other words, the conversion program 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 into the message format corresponding to the SCSI response data DRSCSI. In some embodiments of the present invention, the conversion program 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. Thus, 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 transmitted to the SCSI driver 212C.
Then, when the SCSI driver 212C receives the SCSI response data DRSCSI, the SCSI driver 212C transmits a SCSI response message MRSCSI to the SAS user manager 212A according to the SCSI response data DRSCSI. Finally, the SAS ue 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 MRSCSI, and the display unit 216 displays a screen corresponding to the data content indicated by the SCSI response message MRSCSI according to the output signal SOUT for the user to view the related status of the PCIE device 220.
In summary, through the configuration of the conversion program of the present invention, the SAS user manager originally used for controlling the SCSI device in the management host can be continuously used for control management of the PCIE device, thereby greatly reducing the conversion cost and the re-adaptation time of the user in the related management software, and making the control management of the management host in different interface devices more flexible.
