The server system 100 includes a log server 120 and a rack server system 140-142. The rack server systems 140-142 each include a Rack Management Controller (RMC) 160, a server node 161, a power node 162, and a fan node 163. However, in this embodiment, the functional nodes included in the rack server systems 140-142 are not limited to the above three (the server node 161, the power node 162, and the fan node 163), for example, the rack. The server system 140~142 further includes a storage module, a control module or other modular circuits with equality. In fact, the functional modules included in the rack server system 140~142 are not the first one. The three embodiments of the figure are limited to and may include at least one or more functional modules.
在機架式伺服器系統140~142內，伺服器節點161、電源節點162以及風扇節點163在工作狀態中會產生/提出許多工作狀態資訊(例如轉速、溫度、電壓、硬碟數量、記憶體容量、異常訊息等)，一般來說這些內容又被稱為日誌資訊，為了有效控管這些日誌資訊，這些日誌資訊會被傳送至機架管理單元160，由機架管理單元160再回報給日誌伺服器120。 In the rack server systems 140-142, the server node 161, the power node 162, and the fan node 163 generate/propose many operational status information (such as speed, temperature, voltage, number of hard disks, and memory) in the working state. In general, the content is also called log information. In order to effectively control the log information, the log information is transmitted to the rack management unit 160, and the rack management unit 160 returns the log. Server 120.
在此實施例中，各節點(伺服器節點161、電源節點162以及風扇節點163)與機架管理單元160彼此之間透過ZigBee無線通訊技術來連接。上述日誌資訊可進一步處理轉換為無線信號並藉由ZigBee無線通訊技術傳送至機架管理單元160。須注意的是，傳送過程並非限制於直接傳 送，由於各節點(伺服器節點161、電源節點162以及風扇節點163)彼此之間亦透過ZigBee無線通訊技術連接，上述無線信號可間接傳送至機架管理單元160(例如從伺服器節點161傳送至電源節點162後，再傳送至機架管理單元160)。另外，機架式伺服器系統140~142內的機架管理單元160與日誌伺服器120亦透過ZigBee無線通訊技術連接。也就是說，機架管理單元160接收到的日誌資訊亦藉由ZigBee無線通訊技術回報給日誌伺服器120。因此，本揭示文件利用ZigBee無線通訊技術節省了先前技術中大量的網路線與高成本的交換機，同時也節省了機架式伺服器系統140~142內的空間。 In this embodiment, each node (server node 161, power node 162, and fan node 163) and rack management unit 160 are connected to each other by ZigBee wireless communication technology. The above log information can be further processed and converted into a wireless signal and transmitted to the rack management unit 160 by ZigBee wireless communication technology. It should be noted that the transmission process is not limited to direct transmission. Sending, since each node (server node 161, power node 162, and fan node 163) is also connected to each other through ZigBee wireless communication technology, the wireless signal can be indirectly transmitted to the rack management unit 160 (eg, transmitted from the server node 161). After the power node 162, it is transferred to the rack management unit 160). In addition, the rack management unit 160 and the log server 120 in the rack server systems 140-142 are also connected by ZigBee wireless communication technology. That is to say, the log information received by the rack management unit 160 is also reported to the log server 120 by the ZigBee wireless communication technology. Therefore, the present disclosure utilizes ZigBee wireless communication technology to save a large number of network routes and high cost switches in the prior art, while also saving space in the rack server systems 140-142.
須補充的是，為了控管各節點(伺服器節點161、電源節點162以及風扇節點163)的工作狀態，當上述日誌伺服器120接收到由機架式伺服器系統140~142內各節點(伺服器節點161、電源節點162以及風扇節點163)所產生的日誌資訊後，會將其傳送至客戶端110，使得客戶端110能即時掌握各節點的工作狀態，客戶端110進一步依照其工作狀態資訊(例如轉速、溫度、電壓、硬碟數量、記憶體容量、異常訊息等)各自給予一用以控制之串列通訊信號(例如溫度過高給予一提高風扇轉速信號、電壓過低給予一提昇電壓信號、異常訊息給予一關機信號等)接著，再藉由ZigBee無線通訊技術將串列通訊信號轉換為無線信號後回傳給機架式伺服器系統140~142內的機架管理單元160，機架管理單元160同樣地藉由ZigBee無線通訊技術將對應各節點(伺 服器節點161、電源節點162以及風扇節點163)的無線信號傳送至對應之節點。同樣地，上述無線信號可自機架管理單元160間接傳送至對應之節點(例如從機架管理單元160傳送至伺服器節點161後，再傳送至電源節點162)。 It should be added that, in order to control the working states of the nodes (the server node 161, the power node 162, and the fan node 163), when the log server 120 receives the nodes in the rack server systems 140-142 ( After the log information generated by the server node 161, the power supply node 162, and the fan node 163) is transmitted to the client 110, the client 110 can immediately grasp the working state of each node, and the client 110 further follows its working state. Information (such as speed, temperature, voltage, number of hard disks, memory capacity, abnormal messages, etc.) are each given a serial communication signal for control (for example, if the temperature is too high, an increase in the fan speed signal is given, and the voltage is too low to give an boost. The voltage signal, the abnormal message is given a shutdown signal, etc.), and then the serial communication signal is converted into a wireless signal by ZigBee wireless communication technology, and then transmitted back to the rack management unit 160 in the rack server system 140~142, The rack management unit 160 similarly uses ZigBee wireless communication technology to correspond to each node (serving The wireless signals of the server node 161, the power node 162, and the fan node 163) are transmitted to the corresponding nodes. Similarly, the wireless signals may be indirectly transmitted from the rack management unit 160 to the corresponding node (eg, from the rack management unit 160 to the server node 161 and then to the power node 162).
值得一提的是，機架管理單元160亦可直接將日誌資訊回報給客戶端110而無須透過日誌伺服器120的收集後，再傳送至客戶端110。(在第1圖中無指示，可參考第2圖) It is worth mentioning that the rack management unit 160 can directly report the log information to the client 110 without being collected by the log server 120 and then transmitted to the client 110.

於此實施例中，基板管理控制模組202另外包含控制電路如溫度補償電路、頻率補償電路、開關電路或是 其它具相等性的控制電路，用以改變伺服器節點161之工作狀態(例如降低工作頻率、關閉伺服器等)。若伺服器節點161收到提高工作頻率的控制信號，則基板管理控制模組202利用頻率補償電路將伺服器節點161的工作頻率提高；若伺服器節點161收到伺服器關閉的控制信號，則基板管理控制模組202利用開關電路將伺服器節點161切換到待機模式。 In this embodiment, the substrate management control module 202 further includes a control circuit such as a temperature compensation circuit, a frequency compensation circuit, a switch circuit, or Other equal control circuits are used to change the operating state of the server node 161 (eg, lowering the operating frequency, turning off the server, etc.). If the server node 161 receives the control signal for increasing the operating frequency, the baseboard management control module 202 uses the frequency compensation circuit to increase the operating frequency of the server node 161; if the server node 161 receives the control signal that the server is turned off, The substrate management control module 202 switches the server node 161 to the standby mode using a switch circuit.
如第2圖所示，電源節點162於實施例中為電源供應模組，電源節點162包含電源控制模組222以及ZigBee通訊模組220。電源節點162在工作狀態中會產生/提出許多工作狀態資訊(例如電源節點162的輸出電壓、輸出電流、溫度等)。 As shown in FIG. 2, the power supply node 162 is a power supply module in the embodiment, and the power supply node 162 includes a power control module 222 and a ZigBee communication module 220. The power node 162 generates/proposes a number of operational status information (eg, output voltage, output current, temperature, etc. of the power supply node 162) in the operational state.
於此實施例中，電源控制模組222與基板管理控制模組202不同的是，電源控制模組222所包含的偵測電路為電壓偵測電路、電流偵測電路、溫度偵測電路或是其他具相等性的偵測電路，用以偵測電源節點162之工作狀態，取得電源節點162之電源日誌資訊。因此電源日誌資訊記錄著電源節點162所有不同工作狀態資訊。另外電源控制模組222所包含的控制電路為電壓補償電路、電流補償電路、電源關斷電路或是其它具相等性的控制電路，用以改變電源224之工作狀態(例如升高輸出電壓、降低輸出電流、關閉電源等)。 In this embodiment, the power control module 222 is different from the substrate management control module 202. The detection circuit included in the power control module 222 is a voltage detection circuit, a current detection circuit, a temperature detection circuit, or Other equal-detection circuits are used to detect the working state of the power node 162 and obtain power log information of the power node 162. Therefore, the power log information records all the different working status information of the power node 162. In addition, the control circuit included in the power control module 222 is a voltage compensation circuit, a current compensation circuit, a power shutdown circuit, or other equivalent control circuit for changing the operating state of the power supply 224 (eg, increasing the output voltage, reducing Output current, power off, etc.).
電源控制模組222與基板管理控制模組202同樣地可以產生符合特定數位信號格式例如通用異步收發信 號(UART signal)之電源狀態信號來傳送電源日誌資訊。再藉由ZigBee通訊模組220將電源狀態信號轉換成符合Zigbee協定的無線信號並傳送至機架管理單元160的ZigBee通訊模組260。 The power control module 222 can generate a specific digital signal format, such as a universal asynchronous transceiver, similarly to the substrate management control module 202. The power status signal of the UART signal is used to transmit power log information. The ZigBee communication module 220 converts the power status signal into a Zigbee-compliant wireless signal and transmits it to the ZigBee communication module 260 of the rack management unit 160.
如第2圖所示，風扇節點163於實施例中為風扇模組，風扇節點163包含風扇控制模組242以及ZigBee通訊模組240。風扇節點163在工作狀態中會產生/提出工作狀態資訊(例如風扇節點163的轉速)。 As shown in FIG. 2, the fan node 163 is a fan module in the embodiment, and the fan node 163 includes a fan control module 242 and a ZigBee communication module 240. The fan node 163 generates/proposes operational status information (eg, the rotational speed of the fan node 163) in the operational state.
於此實施例中，風扇控制模組242與基板管理控制模組202不同的是，風扇控制模組242所包含的偵測電路為轉速偵測電路、電流偵測電路或是其他具相等性的偵測電路，用以偵測風扇節點163之工作狀態，取得風扇節點163之風扇日誌資訊。因此風扇日誌資訊記錄著風扇節點163所有不同工作狀態資訊。另外風扇控制模組242所包含的控制電路為電流補償電路、電源關斷電路或是其它具相等性的控制電路，用以改變風扇節點163之工作狀態(例如提高風扇轉速、關閉風扇等)。 In this embodiment, the fan control module 242 is different from the substrate management control module 202. The detection circuit included in the fan control module 242 is a rotation speed detecting circuit, a current detecting circuit, or the like. The detecting circuit is configured to detect the working state of the fan node 163 and obtain the fan log information of the fan node 163. Therefore, the fan log information records all the different working status information of the fan node 163. In addition, the control circuit included in the fan control module 242 is a current compensation circuit, a power shutdown circuit, or other equivalent control circuit for changing the working state of the fan node 163 (for example, increasing the fan speed, turning off the fan, etc.).
須補充的是，上述提到控制信號的判斷/產生並不限制依據對應同一節點的工作狀態資訊，亦即可依據一節點的工作狀態資訊給予另一節點控制信號。舉例來說，伺服器節點161(伺服器模組)之日誌資訊表示其溫度上升，客戶端控制模組292對應其產生的控制信號包含對應風扇節點163(風扇模組)的風扇控制信號，用以驅動風扇節點163的風扇控制模組242進而提高風扇節點163的轉速。 It should be added that the above-mentioned judgment/generation of the control signal does not limit the information according to the working state of the corresponding node, and the control signal of another node can be given according to the working state information of one node. For example, the log information of the server node 161 (server module) indicates that the temperature thereof rises, and the control signal generated by the client control module 292 corresponding to the fan control signal corresponding to the fan node 163 (fan module) is used. The fan control module 242 that drives the fan node 163 further increases the rotational speed of the fan node 163.
風扇控制模組242與基板管理控制模組202同樣地可以產生符合特定數位信號格式，例如通用異步收發信號(UART signal)之風扇狀態信號來傳送風扇日誌資訊。再藉由ZigBee通訊模組240將風扇狀態信號轉換成符合Zigbee協定的無線信號封包並傳送至機架管理單元160的ZigBee通訊模組260。 Similarly to the substrate management control module 202, the fan control module 242 can generate a fan status signal that conforms to a specific digital signal format, such as a universal UART signal, to transmit fan log information. The fan status signal is converted into a Zigbee-compliant wireless signal packet by the ZigBee communication module 240 and transmitted to the ZigBee communication module 260 of the rack management unit 160.
該無線信號傳送回各節點(伺服器節點161、電源節點162以及風扇節點163)與先前的說明相同，在此不另贅述。須注意的是，當基板管理控制模組202、222、242之控制電路接收到不同的控制信號後，依照其信號內容及上述控制電路的功能分別改變伺服器節點161、電源節點162、風扇244之工作狀態，工作狀態如先前的詳細說明，在此不另贅述。 The wireless signal is transmitted back to each node (server node 161, power node 162, and fan node 163) as previously described, and will not be further described herein. It should be noted that after the control circuits of the substrate management control modules 202, 222, and 242 receive different control signals, the server node 161, the power node 162, and the fan 244 are respectively changed according to the contents of the signal and the functions of the control circuit. The working state and working state are as described in the previous detailed description, and are not described here.
