(B)在接收到來自該儲存設備回應於該小型電腦系統介面機箱服務指令而產生，並通過傳輸控制協定和網際網路協定傳送的一小型電腦系統介面機箱服務回覆資料後，將該小型電腦系統介面機箱服務回覆資料封裝為支援Redfish及Swordfish標準之其中一者之資料格式的一標準回覆資料。(B) upon receipt of an SCSI Chassis response data from the storage device in response to the SCSI Chassis command and transmitted via Transmission Control Protocol and Internet Protocol, the SCSI The system interface chassis service response data is packaged as a standard response data in a data format that supports one of the Redfish and Swordfish standards.

本發明的功效在於：藉由該機架管理模組通過傳輸控制協定和網際網路協定傳送該小型電腦系統介面機箱服務(SES)指令至該儲存設備，以直接自該儲存設備獲得該小型電腦系統介面機箱服務回覆資料，此外，藉由該機架管理模組將該小型電腦系統介面機箱服務回覆資料封裝為支援Redfish或Swordfish標準的該標準回覆資料，藉此一遠端的管理端即可利用該機架管理模組封裝好的標準回覆資料直接管理該儲存設備。The effect of the present invention is: the rack management module transmits the Small Computer System Interface Enclosure Service (SES) command to the storage device through the transmission control protocol and the Internet protocol, so as to directly obtain the small computer from the storage device The system interface chassis service reply data, in addition, through the rack management module, the small computer system interface chassis service reply data is packaged into the standard reply data supporting the Redfish or Swordfish standard, so that a remote management terminal can The storage device is directly managed by using the standard reply data encapsulated by the rack management module.

參閱圖2，本發明儲存設備管理方法之實施例，適用於管理一儲存設備11，並藉由一經由一提供小型電腦系統介面機箱服務的區域網路(SES over ethernet)與該儲存設備11連接的機架管理模組12來實施。該機架管理模組12還經由一通訊網路與一主機13及一管理端14連接，該主機13還透過SAS電纜或PCIe與該儲存設備11連接。該儲存設備11、該機架管理模組12及該主機13皆包含一網路卡111、121、131。值得一提的是，圖2僅示例出一台儲存設備11，然而，該儲存設備管理方法亦可管理多台儲存設備11。Referring to Fig. 2, an embodiment of the storage device management method of the present invention is suitable for managing a storage device 11, and is connected with the storage device 11 through a local area network (SES over ethernet) that provides small computer system interface chassis services The rack management module 12 is implemented. The rack management module 12 is also connected to a host 13 and a management terminal 14 via a communication network, and the host 13 is also connected to the storage device 11 via a SAS cable or PCIe. The storage device 11 , the rack management module 12 and the host 13 all include a network card 111 , 121 , 131 . It is worth mentioning that FIG. 2 only illustrates one storage device 11 , however, the storage device management method can also manage multiple storage devices 11 .

該儲存設備11之實施態樣可為一磁碟簇，或一閃存簇等。當該儲存設備11為磁碟簇時，該儲存設備11係透過SAS電纜與該主機13連接，當該儲存設備11為閃存簇時，該儲存設備11係透過PCIe與該主機13連接。該儲存設備11中的網路卡111是該儲存設備11中之擴展器(expander) 晶片中的網路介面，擴展器晶片是回報硬碟狀態以及該儲存設備11的管理核心晶片。The implementation of the storage device 11 can be a cluster of disks, or a cluster of flash memory. When the storage device 11 is a disk cluster, the storage device 11 is connected to the host 13 through a SAS cable, and when the storage device 11 is a flash memory cluster, the storage device 11 is connected to the host 13 through PCIe. The network card 111 in the storage device 11 is the network interface in the expander (expander) chip in the storage device 11 , and the expander chip is the management core chip for reporting the status of the hard disk and the storage device 11 .

該管理端14由一管理者所持有，該管理端14之實施態樣可為一智慧型手機、一平板電腦、一筆記型電腦，或一個人電腦等。The management terminal 14 is held by a manager, and the implementation form of the management terminal 14 can be a smart phone, a tablet computer, a notebook computer, or a personal computer.

參閱圖2與圖3，本發明儲存設備管理方法的實施例包含下列步驟。Referring to FIG. 2 and FIG. 3 , the embodiment of the storage device management method of the present invention includes the following steps.

在步驟31中，在該機架管理模組12經由該通訊網路接收到來自該管理端14之一Redfish指令後，該機架管理模組12將該Redfish指令封裝為一小型電腦系統介面機箱服務(SES)指令，並通過傳輸控制協定和網際網路協定將該小型電腦系統介面機箱服務指令傳送至該儲存設備11。由於該儲存設備11僅可處理SES資料，因此須將Redfish指令封裝成該SES指令，以供該儲存設備11進行相關處理。In step 31, after the rack management module 12 receives a Redfish command from the management terminal 14 via the communication network, the rack management module 12 encapsulates the Redfish command into a small computer system interface chassis service (SES) command, and transmit the SCSI chassis service command to the storage device 11 through transmission control protocol and internet protocol. Since the storage device 11 can only process SES data, the Redfish command must be encapsulated into the SES command for the storage device 11 to perform related processing.

在步驟32中，在該機架管理模組12接收到來自該儲存設備11回應於該SES指令而產生，並通過傳輸控制協定和網際網路協定傳送的一小型電腦系統介面機箱服務(SES)回覆資料後，該機架管理模組12將該SES回覆資料封裝為支援Redfish及Swordfish標準之其中一者之資料格式的一標準回覆資料，並經由該通訊網路將該標準回覆資料傳送至該管理端14，該機架管理模組12係利用網路封包(TCP/IP)的方式封裝該SES回覆資料。圖4示例出被封裝為支援Redfish資料格式的封包內容。In step 32, the rack management module 12 receives a Small Computer System Interface Enclosure Service (SES) generated in response to the SES command from the storage device 11 and transmitted through TCP and Internet Protocol. After replying the data, the rack management module 12 encapsulates the SES reply data into a standard reply data in a data format supporting one of the Redfish and Swordfish standards, and sends the standard reply data to the management via the communication network Terminal 14, the rack management module 12 uses network packet (TCP/IP) to encapsulate the SES reply data. Figure 4 shows an example of the packet content encapsulated to support the Redfish data format.

在本發明之其他實施方式中，也可設計為由該機架管理模組12定期地自動傳送該SES指令至該儲存設備11，而該管理端14在需要時，傳送一與該SES回覆資料相關的資料請求至該機架管理模組12，在該機架管理模組12接收到來自該管理端14之該資料請求後，傳送該標準回覆資料至該管理端14。由於該管理端14係直接與該機架管理模組12溝通，且該機架管理模組12已定期傳送該SES指令至該儲存設備11來取得SES回覆資料，使得該機架管理模組12在收到該管理端14的資料請求後即可直接將定期取得的SES回覆資料封裝為支援Redfish及Swordfish標準之其中一者之資料格式的標準回覆資料後回傳給該管理端14，因此該機架管理模組12無須再將該管理端14的資料請求封裝成一SES資料請求，再轉傳至該儲存設備11來取得SES回覆資料。In other embodiments of the present invention, it can also be designed that the rack management module 12 automatically sends the SES command to the storage device 11 on a regular basis, and the management terminal 14 sends a response data corresponding to the SES when needed. Relevant data requests are sent to the rack management module 12 , and after the rack management module 12 receives the data request from the management terminal 14 , it sends the standard reply data to the management terminal 14 . Since the management terminal 14 communicates directly with the rack management module 12, and the rack management module 12 has regularly sent the SES command to the storage device 11 to obtain SES reply data, the rack management module 12 After receiving the data request from the management terminal 14, the regularly obtained SES reply data can be directly encapsulated into a standard reply data in a data format that supports one of the Redfish and Swordfish standards, and then sent back to the management terminal 14, so the management terminal 14 The rack management module 12 does not need to encapsulate the data request of the management terminal 14 into a SES data request, and then forward it to the storage device 11 to obtain the SES reply data.

綜上所述，本發明儲存設備管理方法，藉由該機架管理模組12通過傳輸控制協定和網際網路協定傳送該小型電腦系統介面機箱服務(SES)指令至該儲存設備11，以直接自該儲存設備11獲得該小型電腦系統介面機箱服務回覆資料，此外，藉由該機架管理模組12將該小型電腦系統介面機箱服務回覆資料封裝為支援Redfish或Swordfish標準的該標準回覆資料，藉此一遠端的管理端14即可利用該機架管理模組12封裝好的標準回覆資料直接管理該儲存設備11，再者，使用現有的Redfish或Swordfish標準亦可減少開發新標準的成本，故確實能達成本發明的目的。In summary, in the storage device management method of the present invention, the rack management module 12 transmits the Small Computer System Interface Enclosure Services (SES) command to the storage device 11 through TCP and Internet Protocol, so as to directly Obtaining the SCSI chassis service reply data from the storage device 11, and packaging the SCSI chassis service reply data into the standard reply data supporting the Redfish or Swordfish standard by the rack management module 12, In this way, a remote management terminal 14 can directly manage the storage device 11 by using the standard reply data packaged by the rack management module 12. Moreover, using the existing Redfish or Swordfish standard can also reduce the cost of developing a new standard , so the purpose of the present invention can indeed be achieved.

惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。But the above-mentioned ones are only embodiments of the present invention, and should not limit the scope of the present invention.
