Description

一般來說,現行的伺服器(Server)普遍強調各自單獨的效能與功效。基於此概念下所設計出的伺服器,講究的是分工、獨立作業。也就是說,各伺服器節點(Server Node)僅針對自身狀況與需求,動態調整自身的能源消耗,以追求自身節能與效能間的平衡。In general, current servers generally emphasize their individual performance and efficacy. Based on the concept of the server designed, the emphasis is on division of labor and independent work.

有關本揭露的特徵與實作,茲配合圖式作實施例詳細說明如下。The features and implementations of the present disclosure are described in detail below with reference to the drawings.
請參考「第1圖」所示,其為本揭露之機櫃的示意圖。機櫃100包括多個主要電源供應器110_1~110_N、多個備用電源供應器120_1~120_N、多個節點130_1~130_M、機櫃管理控制器(Rack Management Controller,RMC)140與控制單元150,其中N、M為大於1的正整數,且N與M可為相同或不同。Please refer to "Figure 1" for a schematic view of the cabinet of the present disclosure. The cabinet 100 includes a plurality of main power supplies 110_1~110_N, a plurality of backup power supplies 120_1~120_N, a plurality of nodes 130_1~130_M, a Rack Management Controller (RMC) 140, and a control unit 150, where M is a positive integer greater than 1, and N and M may be the same or different.
主要電源供應器110_1~110_N用以分別提供一工作電壓。也就是說,當主要電源供應器110_1~110_N為正常狀態時,例如作為提供機櫃100主要的工作電壓。The main power supplies 110_1~110_N are used to respectively provide an operating voltage. That is, when the main power supplies 110_1 110 110_N are in a normal state, for example, as a main operating voltage for providing the cabinet 100.
備用電源供應器120_1~120_N用以分別提供一工作電壓。也就是說,當備用電源供應器120_1~120_N為正常狀態時,例如作為提供機櫃100備用的工作電壓。亦即,當主要電源供應器110_1~110_N全部發生異常時,備用電源供應器120_1~120_N便提供機櫃100的工作電壓,使得機櫃100仍可正常運作。The backup power supplies 120_1~120_N are used to respectively provide an operating voltage. That is to say, when the backup power supplies 120_1~120_N are in a normal state, for example, as an operating voltage for providing the cabinet 100 for standby. That is, when all of the main power supplies 110_1~110_N are abnormal, the backup power supplies 120_1~120_N provide the operating voltage of the cabinet 100, so that the cabinet 100 can still operate normally.
在本實施例中,主要電源供應器110_1~110_N與備用電源供應器120_1~120_N所能提供的最大供應功率值都相同,此最大供 應功率值例如為500W。並且,主要電源供應器110_1~110_N與備用電源供應器120_1~120_N所接收的輸入源不同。舉例來說,主要電源供應器110_1~110_N所接收的輸入源例如為市電,而備用電源供應器120_1~120_N所接收的輸入源例如為電池或其他的儲能元件。In this embodiment, the maximum power supply values that the primary power supply 110_1~110_N and the backup power supply 120_1~120_N can provide are the same. The power value should be, for example, 500W. Also, the primary power supplies 110_1~110_N are different from the input sources received by the backup power supplies 120_1~120_N. For example, the input sources received by the primary power supplies 110_1 110 110_N are, for example, mains, and the input sources received by the backup power supplies 120_1 120 120_N are, for example, batteries or other energy storage components.
節點130_1~130_M用以分別提供功率資訊。進一步來說,節點130_1~130_M例如各自包括基板管理控制器(Baseboard Management Controller,BMC)與連接介面。基板管理控制器用以偵測節點130_1~130_M的運作狀態,以提供節點130_1~130_M的功率資訊。其中,前述功率資訊例如為節點130_1~130_M之電壓、電流及功率消耗等。Nodes 130_1~130_M are used to provide power information separately. Further, the nodes 130_1~130_M each include, for example, a Baseboard Management Controller (BMC) and a connection interface. The baseboard management controller is configured to detect the operating states of the nodes 130_1~130_M to provide power information of the nodes 130_1~130_M. The power information is, for example, the voltage, current, and power consumption of the nodes 130_1~130_M.
在本實施例中,連接介面例如為內部整合電路(Inter Integrate Circuit,I2C)匯流排、序列周邊介面(Serial Peripheral Interface,SPI)匯流排、通用輸入輸出(General Purpose Input Output,GPIO)匯流排。In this embodiment, the connection interface is, for example, an Inter Integrate Circuit (I2C) bus, a Serial Peripheral Interface (SPI) bus, and a General Purpose Input Output (GPIO) bus.
機櫃管理控制器140可透過前述的連接介面耦接節點130_1~130_M的基板管理控制器,用以接收功率資訊(亦即各節點130_1~130_M之電壓、電流及功率消耗等),並依據功率資訊,計算節點130_1~130_M的總功率消耗值。The rack management controller 140 can be coupled to the baseboard management controllers of the nodes 130_1~130_M through the foregoing connection interface for receiving power information (that is, voltage, current, power consumption, etc. of each node 130_1~130_M), and according to the power information. The total power consumption values of the nodes 130_1~130_M are calculated.
接著,機櫃管理控制器140依據總功率消耗值與單一電源供應器的最大供應功率值,計算電源供應器開啟數量。其中,前述單一電源供應器的最大供應功率值例如為500W。進一步來說,電 源供應器開啟數量例如為總功率消耗值除以單一電源供應器的最大供應功率值。Next, the rack management controller 140 calculates the number of power supply ons based on the total power consumption value and the maximum power supply value of the single power supply. Wherein, the maximum power supply value of the foregoing single power supply is, for example, 500W. Further, electricity The source supply open quantity is, for example, the total power consumption value divided by the maximum power supply value of a single power supply.
在一實施例中,假設總功率消耗值為1400W,且單一電源供應器的最大供應功率值為500W,則機櫃管理控制器140會對總功率消耗值與單一電源供應器的最大供應功率值進行計算,以計算出1400W/500W=2.8,亦即電源供應器開啟數量為2.8台。但是,由於電源供應器不會僅開啟0.8台,因此機櫃管理控制器140會將不足1台電源供應器視為1台電源供應器,使得機櫃管理控制器140所計算出來之電源供應器開啟數量為3台。In an embodiment, assuming that the total power consumption value is 1400 W and the maximum power supply value of the single power supply is 500 W, the rack management controller 140 performs the total power consumption value and the maximum power supply value of the single power supply. Calculate to calculate 1400W/500W=2.8, that is, the power supply is turned on by 2.8 units. However, since the power supply does not only open 0.8 units, the cabinet management controller 140 regards less than one power supply as one power supply, so that the number of power supply calculations calculated by the cabinet management controller 140 is It is 3 sets.
在另一實施例中,假設總功率消耗值為1600W,且單一電源供應器的最大供應功率值為500W,則機櫃管理控制器140會對總功率消耗值與單一電源供應器的最大供應功率值進行計算,以計算出1600W/500W=3.2,亦即電源供應器開啟數量為3.2台,而此時機櫃管理控制器140所計算出來之電源供應器開啟數量為4台。In another embodiment, assuming that the total power consumption value is 1600 W and the maximum power supply value of the single power supply is 500 W, the cabinet management controller 140 compares the total power consumption value with the maximum power supply value of the single power supply. The calculation is performed to calculate 1600 W/500 W=3.2, that is, the number of power supply openings is 3.2, and the number of power supply calculations calculated by the cabinet management controller 140 is four.
控制單元150耦接機櫃管理控制器140、主要電源供應器110_1~110_N與備用電源供應器120_1~120_N,用以接收電源供應器開啟數量,產生多個控制訊號,以啟動成對的至少一主要電源供應器與備用電源供應器。在本實施例中,控制單元150例如為複雜可程式邏輯元件(Complex Programming Logic Device,CPLD)。The control unit 150 is coupled to the cabinet management controller 140, the main power supplies 110_1~110_N and the backup power supplies 120_1~120_N for receiving the power supply open quantity, and generating a plurality of control signals to start at least one main pair. Power supply and backup power supply. In this embodiment, the control unit 150 is, for example, a Complex Programming Logic Device (CPLD).
舉例來說,機櫃管理控制器140計算出電源供應器開啟數量 為3台,控制單元150例如產生對應的控制訊號給主要電源供應器110_1~110_3與備用電源供應器120_1~120_3,以啟動主要電源供應器110_1~110_3與備用電源供應器120_1~120_3。For example, the rack management controller 140 calculates the number of power supply open For example, the control unit 150 generates corresponding control signals to the main power supplies 110_1 110 110_3 and the backup power supplies 120_1 120 120_3 to activate the main power supplies 110_1 110 110_3 and the backup power supplies 120_1 120 120_3.
也就是說,控制單元150控制電源供應器的啟動數量是成對的。舉例來說,當機櫃管理控制器140計算出電源供應器開啟數量為1台時,控制單元150會對應啟動主要電源供應器110_1與備用電源供應器120_1。當機櫃管理控制器140計算出電源供應器開啟數量為2台時,控制單元150會對應啟動主要電源供應器110_1~110_2與備用電源供應器120_1~120_2。其餘則類推。That is, the control unit 150 controls the number of startups of the power supply to be paired. For example, when the cabinet management controller 140 calculates that the number of power supply openings is one, the control unit 150 correspondingly activates the primary power supply 110_1 and the backup power supply 120_1. When the cabinet management controller 140 calculates that the number of power supply openers is two, the control unit 150 correspondingly activates the primary power supplies 110_1~110_2 and the backup power supplies 120_1~120_2. The rest is analogous.
進一步來說,前述控制訊號例如包括啟動訊號DC_ON與供電訊號DC_Rapidon。其中,啟動訊號DC_ON用以控制電源供應器是否啟動。舉例來說,當啟動訊號DC_ON為低邏輯準位時,以開啟電源供應器的運作。當啟動訊號DC_ON為高邏輯準位時,以關閉電源供應器的運作。Further, the foregoing control signal includes, for example, an activation signal DC_ON and a power supply signal DC_Rapidon. The start signal DC_ON is used to control whether the power supply is started. For example, when the startup signal DC_ON is at a low logic level, the operation of the power supply is turned on. When the start signal DC_ON is at a high logic level, the power supply is turned off.
供電訊號DC_Rapidon用以控制電源供應器是否供電。舉例來說,當供電訊號DC_Rapidon為高邏輯準位時,以致使電源供應器提供高電壓,例如12.2V,使得節點130_1~130_M利用提供高電壓的電源供應器進行運作。The power supply signal DC_Rapidon is used to control whether the power supply is powered. For example, when the power supply signal DC_Rapidon is at a high logic level, the power supply is supplied with a high voltage, for example, 12.2V, so that the nodes 130_1~130_M operate with a power supply that provides a high voltage.
當供電訊號DC_Rapidon為低邏輯準位時,以致使電源供應器提供低電壓,例如11.9V,使得節點130_1~130_M不會使用提供低電壓的電源供應器進行運作。When the power supply signal DC_Rapidon is at a low logic level, the power supply is supplied with a low voltage, for example, 11.9V, so that the nodes 130_1~130_M do not operate using a power supply that provides a low voltage.
舉例來說,當機櫃管理控制器140計算出電源供應器開啟數 量為1台時,控制單元150會對應產生低邏輯準位的啟動訊號DC_ON與高邏輯準位的供電訊號DC_Rapidon給主要電源供應器110_1,以及低邏輯準位的啟動訊號DC_ON與低邏輯準位的供電訊號DC_Rapidon給備用電源供應器120_1,以啟動主要電源供應器110_1與備用電源供應器120_1運作,並致使主要電源供應器110_1提供高電壓,而備用電源供應器120_1提供低電壓。因此,節點130_1~130_M便以主要電源供應器110_1所提供的工作電壓進行運作,而備用電源供應器120_1則作為備用電源。For example, when the cabinet management controller 140 calculates the number of power supply open When the quantity is one, the control unit 150 correspondingly generates the low logic level enable signal DC_ON and the high logic level power supply signal DC_Rapidon to the main power supply 110_1, and the low logic level start signal DC_ON and the low logic level. The power supply signal DC_Rapidon is supplied to the backup power supply 120_1 to activate the primary power supply 110_1 and the backup power supply 120_1, and causes the primary power supply 110_1 to supply a high voltage, and the backup power supply 120_1 provides a low voltage. Therefore, the nodes 130_1~130_M operate with the operating voltage provided by the primary power supply 110_1, and the backup power supply 120_1 serves as the backup power supply.
另外,控制單元150會對應產生高邏輯準位的啟動訊號DC_ON給主要電源供應器110_2~110_N與備用電源供應器120_2~120_N,以關閉主要電源供應器110_2~110_N與備用電源供應器120_2~120_N運作。如此一來,可達到省電的作用。In addition, the control unit 150 correspondingly generates the high logic level activation signal DC_ON to the main power supply 110_2~110_N and the backup power supply 120_2~120_N to turn off the main power supply 110_2~110_N and the backup power supply 120_2~120_N. Operation. In this way, the role of power saving can be achieved.
在另一實施例中,當機櫃管理控制器140計算出電源供應器開啟數量為2台時,控制單元150會對應產生低邏輯準位的啟動訊號DC_ON與高邏輯準位的供電訊號DC_Rapidon給主要電源供應器110_1~110_2,以及低邏輯準位的啟動訊號DC_ON與低邏輯準位的供電訊號DC_Rapidon給備用電源供應器120_1~120_2,以啟動主要電源供應器110_1~110_2與備用電源供應器120_1~120_2運作,並致使主要電源供應器110_1~110_2提供高電壓,而備用電源供應器120_1~120_2提供低電壓。因此,節點130_1~130_M便以主要電源供應器110_1~110_2所提供的工作電壓進行運作,而備用電源供應器120_1~120_2則作為備用電源。In another embodiment, when the cabinet management controller 140 calculates that the power supply is turned on by two, the control unit 150 correspondingly generates a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon to the main The power supply 110_1~110_2, and the low logic level enable signal DC_ON and the low logic level power supply signal DC_Rapidon are supplied to the backup power supply 120_1~120_2 to activate the main power supply 110_1~110_2 and the backup power supply 120_1~ 120_2 operates and causes the main power supplies 110_1~110_2 to provide a high voltage, while the backup power supplies 120_1~120_2 provide a low voltage. Therefore, the nodes 130_1~130_M operate with the operating voltages provided by the primary power supplies 110_1~110_2, while the backup power supplies 120_1~120_2 serve as backup power supplies.
另外,控制單元150會對應產生高邏輯準位的啟動訊號DC_ON給主要電源供應器110_3~110_N與備用電源供應器120_3~120_N,以關閉主要電源供應器110_3~110_N與備用電源供應器120_3~120_N運作。如此一來,可達到省電的作用。其餘則類推。In addition, the control unit 150 correspondingly generates the high logic level activation signal DC_ON to the main power supply 110_3~110_N and the backup power supply 120_3~120_N to turn off the main power supply 110_3~110_N and the backup power supply 120_3~120_N Operation. In this way, the role of power saving can be achieved. The rest is analogous.
在主要電源供應器110_1~110_N與備用電源供應器120_1~120_N啟動後,會回傳一電源良好訊號,以表示主要電源供應器110_1~110_N與備用電源供應器120_1~120_N是否正常。接著,電源良好訊號例如可回傳至控制單元150,以便控制單元150可據此判斷主要電源供應器110_1~110_N與備用電源供應器120_1~120_N是否為正常狀態。After the primary power supplies 110_1~110_N and the backup power supplies 120_1~120_N are activated, a power good signal is returned to indicate whether the primary power supplies 110_1~110_N and the backup power supplies 120_1~120_N are normal. Then, the power good signal can be returned to the control unit 150, for example, so that the control unit 150 can determine whether the primary power supply 110_1~110_N and the backup power supply 120_1~120_N are in a normal state.
舉例來說,當電源良好訊號為高邏輯準位時,表示主要電源供應器110_1~110_N與備用電源供應器120_1~120_N為正常狀態。當電源良好訊號為低邏輯準位時,表示主要電源供應器110_1~110_N與備用電源供應器120_1~120_N不為正常狀態。For example, when the power good signal is at a high logic level, it indicates that the main power supplies 110_1 110 110_N and the backup power supplies 120_1 120 120_N are in a normal state. When the power good signal is at a low logic level, it indicates that the main power supplies 110_1~110_N and the backup power supplies 120_1~120_N are not in a normal state.
假設主要電源供應器110_1~110_3啟動,若控制單元150接收到主要電源供應器110_2所產生的電源良好訊號為低邏輯準位,表示主要電源供應器110_2發生異常或損壞,則控制單元150會將異常狀態回報給機櫃管理控制器140,並產生控制訊號(低邏輯準位的啟動訊號DC_ON與高邏輯準位的供電訊號DC_Rapidon)給主要電源供應器110_4,以啟動主要電源供應器110_4。Assuming that the main power supply 110_1~110_3 is activated, if the control unit 150 receives the power good signal generated by the main power supply 110_2 as a low logic level, indicating that the main power supply 110_2 is abnormal or damaged, the control unit 150 will The abnormal state is reported to the rack management controller 140, and a control signal (a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon) is generated to the main power supply 110_4 to activate the main power supply 110_4.
然而,在控制單元150產生控制訊號給主要電源供應器110_4後,若控制單元150仍接收到主要電源供應器110_4所產生的電源良好訊號為低邏輯準位,表示主要電源供應器110_2發生異常或損壞,則控制單元150會將異常狀態回報給機櫃管理控制器140,並產生控制訊號(低邏輯準位的啟動訊號DC_ON與高邏輯準位的供電訊號DC_Rapidon)給主要電源供應器110_5,以啟動主要電源供應器110_5。其餘則類推。However, after the control unit 150 generates the control signal to the main power supply 110_4, if the control unit 150 still receives the power good signal generated by the main power supply 110_4 as a low logic level, it indicates that the main power supply 110_2 is abnormal or If the damage occurs, the control unit 150 reports the abnormal state to the rack management controller 140, and generates a control signal (a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon) to the main power supply 110_5 to start. Main power supply 110_5. The rest is analogous.
另外,當控制單元150判斷出主要電源供應器發生異常時,控制單元150會進一步判斷發生異常之主要電源供應器是否為主要電源供應器110_1~110_N的最後一個,即主要電源供應器110_N。若判斷出發生異常之主要電源供應器不為最後一個主要電源供應器110_N,控制單元150會對應產生控制訊號,以啟動下一個主要電源供應器。In addition, when the control unit 150 determines that an abnormality occurs in the main power supply, the control unit 150 further determines whether the main power supply that has an abnormality is the last one of the main power supplies 110_1 110 110_N, that is, the main power supply 110_N. If it is determined that the main power supply that is abnormal is not the last main power supply 110_N, the control unit 150 generates a control signal correspondingly to start the next main power supply.
若判斷出發生異常之主要電源供應器為最後一個主要電源供應器110_N,控制單元150會產生高邏輯準位的供電訊號DC_Rapidon給備用電源供應器120_1,以使備用電源供應器120_1由提供低電壓轉換為提供高電壓,使得機櫃100仍可正常運作。If it is determined that the main power supply that is abnormal is the last main power supply 110_N, the control unit 150 generates a high logic level power supply signal DC_Rapidon to the backup power supply 120_1, so that the backup power supply 120_1 is supplied with a low voltage. The conversion to provide a high voltage allows the cabinet 100 to still function properly.
若是主要電源供應器110_1~110_N所接收之輸入源發生異常(例如發生停電的狀況),則主要電源供應器110_1~110_N未接收到輸入源,而對應產生低邏輯準位的電源良好訊號。因此,當控制單元150判斷出所有啟動之主要電源供應器110_1~110_3所產生的電源良好訊號都為低邏輯準位時,表示所有主要電源供應器 110_1~110_3發生異常,則控制單元150例如產生高邏輯準位的供電訊號DC_Rapidon給對應數量之備用電源供應器120_1~120_3,備用電源供應器120_1~120_3便由提供低電壓轉換成提供高電壓,以提供節點130_1~130_M所需的工作電源,使得機櫃100仍可正常運作。如此一來,可避免電源供應器發生異常時,機櫃100無法運作的情況發生。If an abnormality occurs in the input source received by the main power supply 110_1~110_N (for example, a power failure occurs), the main power supply 110_1~110_N does not receive the input source, and correspondingly generates a power good signal with a low logic level. Therefore, when the control unit 150 determines that the power good signals generated by all the activated main power supplies 110_1~110_3 are low logic levels, it indicates that all the main power supplies are provided. If an abnormality occurs in 110_1~110_3, the control unit 150 generates, for example, a high logic level power supply signal DC_Rapidon to a corresponding number of backup power supplies 120_1~120_3, and the backup power supply 120_1~120_3 is converted to provide a high voltage by providing a low voltage. In order to provide the working power required by the nodes 130_1~130_M, the cabinet 100 can still operate normally. In this way, it can be avoided that the cabinet 100 cannot operate when an abnormality occurs in the power supply.
另外,若是控制單元150判斷出所有啟動之主要電源供應器所產生的電源良好訊號並沒有都為低邏輯準位,則可參考前述主要電源供應器110_2發生異常的操作範例,故在此不再贅述。In addition, if the control unit 150 determines that the power good signals generated by all the activated main power supplies are not all low logic levels, reference may be made to the operation example in which the main power supply 110_2 is abnormal, so it is no longer Narration.
