The second logic circuit device 41 obtains the first operation data stored in the first register according to the second logic signal group. Send a corresponding notification signal with a second operation data to the second operation processor 43, the second operation processor 43 operates in the passive mode according to the second operation data of the notification signal, and then controls the second operation processor 43. The second clock generator 42 generates the second control signal and transmits it to the second backplane control terminal I2. The second control signal is the clock signal. The second operation processor 43 obtains another part of the second operation data. One implementation is that the second logic circuit device 41 generates and stores the second operating data in a second register of itself according to the second logic signal group, and the second arithmetic processor 43 indirectly through other chips or The second operating data stored in the second register is directly obtained from the second logic circuit device 41 .
當該固態硬碟5是雙埠類型，且該第一伺服器3處於主動模式、該第二伺服器4存在且處於被動模式時，由處於主動模式的該第一伺服器3輸出該切換訊號，處於被動模式的該第二伺服器4不輸出該切換訊號，接著，該第一資料分配器25根據來自該第一伺服器3的該切換訊號，使其該第一分配組的一端A0的第一控制訊號傳輸到該第一分配傳輸端Y，再由該第一分配傳輸端Y傳送到該第一背板傳輸端O1以供該固態硬碟5經由第一硬碟端SD1(其定義是包括多個PIN腳的IO埠)所接收，使該固態硬碟5可以透過該第一背板傳輸端O1的第一硬碟端SD1及該第一資料分配器25來與該第一伺服器3溝通，該第二資料分配器26根據來自該第一伺服器3的該切換訊號，使其該第二分配傳輸端Y’的第二控制訊號傳輸到該第二分配組的另一端B3，再由該第二分配組的另一端B3傳送到該第二背板傳輸端O2以供該固態硬碟5經由第二硬碟端SD2(其定義是包括多個PIN腳的IO埠)所接收，且使該固態硬碟5的第二硬碟端SD2也可以透過第二背板傳輸端O2及該第二資料分配器26來與該第二伺服器4溝通。因而該第一伺服器3與該第二伺服器4分別可經由該第一資料分配器25，該第二資料分配器26而可傳輸訊號到雙埠類型的固態硬碟5，即使該固態硬碟5為單埠類型的固態硬碟5，也能確保處於主動模式的第一伺服器3可以透過第一資料分配器25、第一背板傳輸端O1及經由第一硬碟端SD1來與固態硬碟5溝通或進行資料傳輸。上述說明僅以當下運作中的伺服器所要讀取的其中一固態硬碟為例，但不以此為限，在此需進一步說明的是，本案的固態硬碟5的數量可以是複數個，也就是說，第一伺服器3及第二伺服器4均透過背板模組2連接多個固態硬碟5，其中，當該固態硬碟5是雙埠類型時，該背板模組2是透過第一背板傳輸端O1及第二背板傳輸端O2分別連接雙埠類型的固態硬碟5的第一硬碟端SD1及第二硬碟端SD2；當該固態硬碟是單埠類型時，該背板模組2僅透過第一背板傳輸端O1連接固態硬碟5的該第一硬碟端SD1，且該背板模組2的第二背板傳輸端O2不連接固態硬碟5。When the solid state drive 5 is a dual-port type, and the first server 3 is in active mode, and the second server 4 exists and is in passive mode, the first server 3 in active mode outputs the switching signal. , the second server 4 in passive mode does not output the switching signal, and then the first data distributor 25 makes one end A0 of the first distribution group according to the switching signal from the first server 3 The first control signal is transmitted to the first distribution transmission terminal Y, and then transmitted from the first distribution transmission terminal Y to the first backplane transmission terminal O1 for the solid state drive 5 to pass through the first hard disk terminal SD1 (its definition is received by an IO port including a plurality of PIN pins, so that the solid state drive 5 can communicate with the first server through the first hard disk end SD1 of the first backplane transmission end O1 and the first data distributor 25 The second data distributor 26 communicates with the server 3, and the second data distributor 26 transmits the second control signal of the second distribution transmission end Y' to the other end B3 of the second distribution group according to the switching signal from the first server 3. , and then transmitted from the other end B3 of the second distribution group to the second backplane transmission end O2 for the solid state drive 5 to be transmitted through the second hard disk end SD2 (which is defined as an IO port including multiple PIN pins) Receive, and enable the second hard disk end SD2 of the solid state drive 5 to communicate with the second server 4 through the second backplane transmission end O2 and the second data distributor 26 . Therefore, the first server 3 and the second server 4 can respectively transmit signals to the dual-port type solid state drive 5 through the first data distributor 25 and the second data distributor 26, even if the solid state drive 5 Disk 5 is a local type solid state drive 5, which also ensures that the first server 3 in the active mode can communicate with the first data distributor 25, the first backplane transmission terminal O1 and the first hard disk terminal SD1. SSD 5 communicates or performs data transfer. The above description only takes one of the solid state drives to be read by the currently operating server as an example, but is not limited to this. What needs to be further explained here is that the number of solid state drives 5 in this case can be plural. That is to say, both the first server 3 and the second server 4 are connected to multiple solid-state drives 5 through the backplane module 2. When the solid-state drives 5 are dual-port types, the backplane module 2 The first backplane transmission terminal O1 and the second backplane transmission terminal O2 are respectively connected to the first hard disk terminal SD1 and the second hard disk terminal SD2 of the dual-port type solid state disk 5; when the solid state disk is a local port type, the backplane module 2 is only connected to the first hard disk terminal SD1 of the solid state drive 5 through the first backplane transmission terminal O1, and the second backplane transmission terminal O2 of the backplane module 2 is not connected to the solid state disk 5 Hard drive 5.

A control signal is transmitted to the first distribution transmission terminal Y, and then transmitted from the first distribution transmission terminal Y to the first backplane transmission terminal O1 for the solid state drive 5 to receive through the first hard disk terminal SD1, so that The solid state drive 5 can communicate with the first server 3 through the first hard drive terminal SD1, the first output terminal O1 and the first data distributor 25. The second data distributor 26 is configured according to the data from the first data distributor. The switching signal of the server 4 causes the second control signal of the second distribution transmission end Y' to be transmitted to the other end B3 of the second distribution group, and then transmitted from the other end B3 of the second distribution group to the third The two backplane transmission terminals O2 are for the solid state drive 5 to receive through the second hard disk terminal SD2, so that the solid state hard disk 5 can distribute through the second hard disk terminal SD2, the second output terminal O2 and the second data The server 26 is used to communicate with the second server 4, so the first server 3 and the second server 4 can respectively pass the first data distributor 25, and the second data distributor 26 can transmit signals to both parties.

第三實施例。Third embodiment.
參閱圖4，為本發明伺服系統的一第三實施例，與該第一實施例的差別在於，該第二伺服器4是處於非預備狀態，也就是未開機狀態/不存在狀態/維修狀態而不輸出邏輯準位為0的第二存在訊號，因此，該第一偵測存在端PEER_PRSNT1未收到第二存在訊號而處於預設為1的邏輯準位，且連接該背板模組2的該固態硬碟5可以屬於雙埠類型也可以屬於單埠類型，以下以連接於背板模組2的固態硬碟5屬於單埠類型，且是經由其第一硬碟端SD1連接於背板模組2的第一背板傳輸端O1為例，因此僅由該第一伺服器3的該第一邏輯電路裝置31根據該第一邏輯訊號組產生該通知訊號與該切換訊號，且由該第一運算處理器33根據該通知訊號控制該第一時脈產生器32產生該第一控制訊號並經由該第一背板控制端I1傳送到該第一資料分配器25，再由該第一資料分配器25根據該切換訊號將該第一控制訊號傳送到該第一背板傳輸端O1以供該固態硬碟5的第一硬碟端SD1所接收，此時，該第一控制訊號是該時鐘訊號。Referring to Figure 4, a third embodiment of the servo system of the present invention is shown. The difference from the first embodiment is that the second server 4 is in a non-preparatory state, that is, not powered on/non-existent/maintained. Instead of outputting the second presence signal with a logic level of 0, the first detection presence terminal PEER_PRSNT1 does not receive the second presence signal and is at a default logic level of 1, and is connected to the backplane module 2 The solid state drive 5 can be of dual port type or single port type. In the following, the solid state hard drive 5 connected to the backplane module 2 belongs to the single port type and is connected to the backplane via its first hard disk end SD1.

A data distributor 25 transmits the first control signal to the first backplane transmission terminal O1 according to the switching signal for reception by the first hard disk terminal SD1 of the solid state disk 5. At this time, the first control signal is the clock signal.
當該固態硬碟5是單埠類型，且該第一伺服器3處於預備狀態，也就是開機狀態/運作狀態、該第二伺服器4處於非預備狀態，也就是未開機狀態/不存在狀態/維修狀態而不輸出邏輯準位為0的第二存在訊號時，該第一偵測存在端未收到第二存在訊號而處於預設為1的邏輯準位，因此，該第一伺服器3更產生一切換訊號到該第一資料分配器25與該第二資料分配器26，使該第一資料分配器25根據該切換訊號將其該第一分配組的一端A0所接收來自該第一伺服器3的第一控制訊號傳輸到該第一分配傳輸端Y，再由該第一分配傳輸端Y傳送到該第一背板傳輸端O1以供該固態硬碟的第一硬碟端SD1所接收，使該固態硬碟5可以透過第一硬碟端SD1、該第一輸出端O1及該第一資料分配器25來與該第一伺服器3溝通，因而可傳輸訊號到單埠類型的固態硬碟5。When the solid state drive 5 is a local port type, and the first server 3 is in a standby state, that is, a powered on state/operational state, the second server 4 is in a non-ready state, that is, not powered on/does not exist. /When the maintenance state does not output the second presence signal with a logic level of 0, the first detection presence terminal does not receive the second presence signal and is at the default logic level of 1.

The first control signal of a server 3 is transmitted to the first distribution transmission terminal Y, and then transmitted from the first distribution transmission terminal Y to the first backplane transmission terminal O1 for the first hard disk terminal of the solid state drive. SD1 receives it, so that the solid state drive 5 can communicate with the first server 3 through the first hard drive end SD1, the first output end O1 and the first data distributor 25, and thus can transmit the signal to the local port. Type SSD 5.
第四實施例Fourth embodiment
參閱圖5，為本發明伺服系統的一第四實施例，與該第二實施例的差別在於，該第二伺服器4是處於非預備狀態，也就是未開機狀態/不存在狀態/維修狀態而不輸出邏輯準位為0的第二存在訊號，因此，該第一偵測存在端PEER_PRSNT1未收到第二存在訊號而處於預設為1的邏輯準位，且連接該背板模組2的該固態硬碟5可以屬於雙埠類型也可以屬於單埠類型，以下以連接於背板模組2的固態硬碟5屬於單埠類型，且是經由其第一硬碟端SD1連接於背板模組2的第一背板傳輸端O1為例，該第一伺服器3根據接收的該第一邏輯訊號組對應於該主動模式的該邏輯訊號組，選擇由該第一資料分配器25切換連接該第一伺服器3與該固態硬碟以做為傳輸路徑，並由該第一邏輯電路裝置31本身產生的該第一控制訊號，並藉由該第一資料分配器25傳送到該固態硬碟5經由該第一硬碟端SD1所接收，此外，該第一控制訊號是該重置訊號。Referring to Figure 5, a fourth embodiment of the servo system of the present invention is shown. The difference from the second embodiment is that the second server 4 is in a non-preparatory state, that is, not powered on/non-existent/maintained. Instead of outputting the second presence signal with a logic level of 0, the first detection presence terminal PEER_PRSNT1 does not receive the second presence signal and is at a default logic level of 1, and is connected to the backplane module 2 The solid state drive 5 can be of dual port type or single port type. In the following, the solid state hard drive 5 connected to the backplane module 2 belongs to the single port type and is connected to the backplane via its first hard disk end SD1. Taking the first backplane transmission end O1 of the board module 2 as an example, the first server 3 selects the first data distributor 25 according to the received first logical signal group corresponding to the logical signal group in the active mode. The first server 3 and the solid state drive are switched as transmission paths, and the first control signal generated by the first logic circuit device 31 itself is transmitted to the first data distributor 25 The solid state drive 5 is received through the first hard drive terminal SD1. In addition, the first control signal is the reset signal.
在上述該第四實施例中，即使該背板模組2所連接的固態硬碟5屬於雙埠類型，該第一資料分配器25與該第二資料分配器25的切換機制與第四實施例中背板模組2連接單埠類型的固態硬碟5的切換機制相同，也就是說，該第一伺服器3根據對應於該主動狀態的該邏輯訊號組，選擇該第一資料分配器25做為該第一控制訊號傳輸路徑，並由該第一邏輯電路裝置31本身產生該第一控制訊號，並藉由該第一資料分配器25傳送到該固態硬碟5，因而可傳輸訊號到單埠類型或雙埠類型的固態硬碟。In the above fourth embodiment, even if the solid state drive 5 connected to the backplane module 2 is of dual-port type, the switching mechanism of the first data distributor 25 and the second data distributor 25 is different from the fourth implementation. In the example, the switching mechanism of the backplane module 2 connected to the local type solid state drive 5 is the same. That is to say, the first server 3 selects the first data allocator according to the logical signal group corresponding to the active state. 25 serves as the first control signal transmission path, and the first logic circuit device 31 itself generates the first control signal and transmits it to the solid state drive 5 through the first data distributor 25, so that the signal can be transmitted To a single port type or dual port type solid state drive.
第五實施例Fifth embodiment
參閱圖6，為本發明伺服系統的一第五實施例，其與該第一實施例的差別在於，該第一伺服器3處於非預備狀態，也就是未開機狀態/不存在狀態/維修狀態而不輸出邏輯準位為0的第一存在訊號，因此，該第二偵測存在端PEER_PRSNT2未收到第一存在訊號而處於預設為1的邏輯準位，且連接該背板模組2的該固態硬碟5可以屬於雙埠類型也可以屬於單埠類型，以下以連接於背板模組2的固態硬碟5屬於單埠類型，且是經由其第一硬碟端SD1連接於背板模組2的第一背板傳輸端O1為例，該第二伺服器4處於預備狀態，也就是開機狀態/運作狀態，因此在該第五實施例中，該第一伺服器3不產生該切換訊號，該第二伺服器4根據該第二邏輯訊號組對應的被動模式及未收到第一伺服器3所傳送的第一存在訊號的狀態，而使第二伺服器4運作於主動模式，並產生該第二控制訊號與該切換訊號，並由該第二資料分配器26根據該切換訊號將該第二控制訊號傳送到該第一資料分配器25，且該第一資料分配器25根據該切換訊號將該第二控制訊號傳送到該第一背板傳輸端O1以供該固態硬碟5經由該第一硬碟端SD1所接收，更詳細而言，該第二資料分配器26的該第二控制端S2根據該切換訊號選擇由其第二分配傳輸端Y’將該第二控制訊號傳輸到該第二分配組的一端B2，並傳送到該第一資料分配器25的該第一分配組的另一端A1，該第一資料分配器25根據該切換訊號，使該第一分配組的另一端A1接收的該第二控制訊號傳輸到該第一分配傳輸端Y，此時該第二控制訊號是該時鐘訊號及該重置訊號其中至少一者。Referring to Figure 6, a fifth embodiment of the servo system of the present invention is shown. The difference from the first embodiment is that the first server 3 is in a non-preparatory state, that is, not powered on/non-existent/maintained. Instead of outputting the first presence signal with a logic level of 0, the second presence detection terminal PEER_PRSNT2 does not receive the first presence signal and is at a default logic level of 1, and is connected to the backplane module 2 The solid state drive 5 can be of dual port type or single port type. In the following, the solid state hard drive 5 connected to the backplane module 2 belongs to the single port type and is connected to the backplane via its first hard disk end SD1. Taking the first backplane transmission end O1 of the board module 2 as an example, the second server 4 is in a ready state, that is, a power-on state/operating state. Therefore, in the fifth embodiment, the first server 3 does not generate According to the switching signal, the second server 4 causes the second server 4 to operate in the active mode according to the passive mode corresponding to the second logical signal group and the state of not receiving the first presence signal sent by the first server 3. mode, and generate the second control signal and the switching signal, and the second data distributor 26 transmits the second control signal to the first data distributor 25 according to the switching signal, and the first data distributor 25 25. According to the switching signal, the second control signal is transmitted to the first backplane transmission terminal O1 for the solid state drive 5 to receive through the first hard disk terminal SD1. More specifically, the second data distributor The second control terminal S2 of 26 selects its second distribution transmission terminal Y' according to the switching signal to transmit the second control signal to one terminal B2 of the second distribution group and transmits it to the first data distributor 25 At the other end A1 of the first distribution group, the first data distributor 25 transmits the second control signal received by the other end A1 of the first distribution group to the first distribution transmission end Y according to the switching signal. When the second control signal is at least one of the clock signal and the reset signal.
在上述該第五實施例中，當該固態硬碟5是雙埠類型(圖未示)，該第一資料分配器25與該第二資料分配器25的切換機制與第五實施例中背板模組2連接單埠類型的固態硬碟5的切換機制相同，也就是說，該第一伺服器3處於未開機狀態/不存在狀態而不輸出邏輯準位為0的第一存在訊號、該第二伺服器4處於開機狀態而運作於主動模式時，該第二伺服器4更產生一切換訊號到該第一資料分配器25與該第二資料分配器26，使該第二資料分配器26根據來自該第二伺服器4的該切換訊號，使其該第二分配傳輸端Y’的第二控制訊號傳輸到該第二分配組的一端B2，再由該第二資料分配器26的第二分配組的一端B2由傳到該第一資料分配器25的第一分配組的另一端A1，再由該第一資料分配器25根據來自該第二伺服器4的該切換訊號使其該第一分配組的另一端A1的第二控制訊號傳輸到該第一分配傳輸端Y，再由該輸出端傳Y送到該第一背板傳輸端O1以供雙埠類型的該固態硬碟5經由該第一硬碟端SD1所接收，因而可傳輸第一控制訊號至電連接於該第一背板傳輸端O1的單埠類型的固態硬碟5或是同時連接第一背板傳輸端O1及第二背板傳輸端O2的雙埠類型的固態硬碟(圖未示)。綜上，由第一實施例的圖2、第三實施例的圖4、第五實施例的圖6可知無論固態硬碟5為雙埠類型或單埠類型時，該第一資料分配器25與該第二資料分配器26受一切換信號的控制，以將該第一控制訊號與該第二控制訊號的至少之一傳送到該該第一背板傳輸端O1與該第二背板傳輸端O2的至少之一，以根據各伺服器的預備狀態，也就是開關機狀態/連接狀態/運作狀態，自動切換至僅經由第一硬碟端SD1或是經由經由其第一硬碟端SD1及經由其第二硬碟端SD2來與固態硬碟溝通，達成皆可與雙埠/單埠傳輸類型的固態硬碟溝通及傳輸資訊的目的。In the above fifth embodiment, when the solid state drive 5 is a dual-port type (not shown), the switching mechanism of the first data allocator 25 and the second data allocator 25 is the same as that in the fifth embodiment. The switching mechanism of the board module 2 connected to the solid state drive 5 of the local port type is the same, that is to say, the first server 3 is in the unpowered state/absent state and does not output the first presence signal with a logic level of 0. When the second server 4 is powered on and operates in the active mode, the second server 4 further generates a switching signal to the first data distributor 25 and the second data distributor 26 so that the second data distributor The controller 26 transmits the second control signal of the second distribution transmission end Y' to one end B2 of the second distribution group according to the switching signal from the second server 4, and then the second data distributor 26 One end B2 of the second distribution group is transmitted to the other end A1 of the first distribution group of the first data distributor 25, and then the first data distributor 25 uses the switching signal from the second server 4. The second control signal from the other end A1 of the first distribution group is transmitted to the first distribution transmission terminal Y, and then transmitted from the output terminal Y to the first backplane transmission terminal O1 for the dual-port type of solid state The hard disk 5 is received through the first hard disk terminal SD1, so that the first control signal can be transmitted to the local type solid state disk 5 electrically connected to the first backplane transmission terminal O1 or simultaneously connected to the first backplane. The transmission terminal O1 and the second backplane transmission terminal O2 are dual-port solid state drives (not shown). In summary, it can be seen from FIG. 2 of the first embodiment, FIG. 4 of the third embodiment, and FIG. 6 of the fifth embodiment that the first data allocator 25 does not matter whether the solid state drive 5 is a dual-port type or a single-port type. The second data distributor 26 is controlled by a switching signal to transmit at least one of the first control signal and the second control signal to the first backplane transmission terminal O1 and the second backplane transmission At least one of the terminals O2 can automatically switch to only the first hard disk terminal SD1 or the first hard disk terminal SD1 according to the preparation status of each server, that is, the power on/off status/connection status/operation status. And communicates with the solid-state drive through its second hard drive terminal SD2, achieving the purpose of communicating and transmitting information with dual-port/single-port transmission type solid-state drives.
第六實施例Sixth embodiment
參閱圖7，為本發明伺服系統的一第六實施例，與該第二實施例的差別在於，該第一伺服器3處於非預備狀態，也就是未開機狀態/不存在狀態/維修狀態而不輸出邏輯準位為0的第一存在訊號，因此，該第二偵測存在端PEER_PRSNT2未收到第一存在訊號而處於預設為1的邏輯準位，且連接該背板的該固態硬碟5可以屬於雙埠類型也可以屬於單埠類型，以下以連接於背板模組2的固態硬碟5屬於單埠類型，且是經由其第一硬碟端SD1連接於背板2的第一背板傳輸端O1為例，該第二伺服器4根據接收的該第二邏輯訊號組對應的被動模式及未收到第一伺服器3所傳送的第一存在訊號而運作於主動模式，選擇依序由該第二資料分配器26、該第一資料分配器25做為傳輸路徑，並由該第二邏輯電路裝置41本身產生該第二控制訊號，再藉由該第二資料分配器26、該第一資料分配器25傳送到該固態硬碟5經由該第一硬碟端SD1所接收，此外，該第二控制訊號是該重置訊號。Referring to Figure 7, a sixth embodiment of the servo system of the present invention is shown. The difference from the second embodiment is that the first server 3 is in a non-preparatory state, that is, not powered on/non-existent/maintenance state. The first presence signal with a logic level of 0 is not output. Therefore, the second presence detection terminal PEER_PRSNT2 does not receive the first presence signal and is at a default logic level of 1, and the solid state hard drive connected to the backplane Disk 5 can be of the dual-port type or the single-port type. In the following, the solid-state hard drive 5 connected to the backplane module 2 belongs to the single-port type and is connected to the third hard disk of the backplane 2 via its first hard disk terminal SD1. Taking the backplane transmission terminal O1 as an example, the second server 4 operates in the active mode according to the passive mode corresponding to the received second logical signal group and the first presence signal sent by the first server 3. The second data distributor 26 and the first data distributor 25 are selected as transmission paths in sequence, and the second logic circuit device 41 itself generates the second control signal, and then uses the second data distributor 41 to generate the second control signal. 26. The first data distributor 25 transmits it to the solid state hard disk 5 and receives it through the first hard disk terminal SD1. In addition, the second control signal is the reset signal.
在上述該第六實施例中，當該固態硬碟5是雙埠類型，該第一資料分配器25與該第二資料分配器25的切換機制與第六實施例中背板2連接單埠類型的固態硬碟5的切換機制相同，也就是說，該第二伺服器4根據接收的該第二邏輯訊號組對應的被動模式及未收到第一伺服器3所傳送的第一存在訊號而運作於主動模式，選擇依序以該第二資料分配器26、該第一資料分配器25做為該第二控制訊號的傳輸路徑，並由該第二邏輯電路裝置41本身產生該第二控制訊號，再藉由該第二資料分配器26、該第一資料分配器25傳送到屬於雙埠類型的該固態硬碟5經由該第一硬碟端SD1所接收，因而可傳輸第二控制訊號至電連接於該第一背板傳輸端O1的單埠類型的固態硬碟，也可以傳輸第二控制訊號至電連接於該第一背板傳輸端O1及第二背板傳輸端O2的雙埠類型的固態硬碟。In the above-mentioned sixth embodiment, when the solid state drive 5 is a dual-port type, the switching mechanism of the first data distributor 25 and the second data distributor 25 is the same as that of the backplane 2 in the sixth embodiment. The switching mechanism of the solid state drives 5 is the same. That is to say, the second server 4 receives the passive mode corresponding to the second logical signal group and does not receive the first presence signal sent by the first server 3. When operating in the active mode, the second data distributor 26 and the first data distributor 25 are selected as the transmission path of the second control signal in sequence, and the second logic circuit device 41 itself generates the second control signal. The control signal is then transmitted through the second data distributor 26 and the first data distributor 25 to the solid state hard drive 5 belonging to the dual-port type and is received through the first hard disk terminal SD1, so that the second control signal can be transmitted The signal is sent to a local solid state drive electrically connected to the first backplane transmission terminal O1, and the second control signal can also be transmitted to a second control signal electrically connected to the first backplane transmission terminal O1 and the second backplane transmission terminal O2. Dual-port type solid state drive.
綜上所述，上述實施例的優點在於：設計在背板模組2中第一資料分配器25與第二資料分配器26的電路連接，與控制二分配器25、26的切換來傳送分別來自第一控制信號與第一控制信號到固態硬碟5，而無論固態硬碟5是雙埠類型或單埠類型時，且不論背板模組2同時連接第一伺服器3及第二伺服器4還是背板模組2僅連接第一伺服器3及第二伺服器4其中任一者，皆能經由切換信號對背板模組2的傳輸路徑切換，而使第一、第二伺服器3、4能經由背板模組2的第一資料分配器25與第二資料分配器26傳送信號到固態硬碟的第一硬碟端SD1，而不至於使連接背板模組2且不具有第二硬碟端SD2的單埠類型的固態硬碟5，在背板模組2僅連接第一伺服器3及第二伺服器4其中任一者時，發生常常無法與固態硬碟5溝通的窘境。因此，達到使雙節點伺服系統內部的伺服器皆可與雙埠傳輸類型及單埠傳輸類型的固態硬碟傳輸資訊的目的，故確實能達成本發明的目的。To sum up, the advantage of the above embodiment is that: the circuit connection between the first data distributor 25 and the second data distributor 26 is designed in the backplane module 2, and the switching of the two distributors 25, 26 is controlled to transmit the respective data. From the first control signal and the first control signal to the solid state drive 5, no matter the solid state drive 5 is a dual port type or a single port type, and no matter the backplane module 2 is connected to the first server 3 and the second servo at the same time, Either the server 4 or the backplane module 2 is only connected to the first server 3 and the second server 4, the transmission path of the backplane module 2 can be switched through the switching signal, so that the first and second servers The devices 3 and 4 can transmit signals to the first hard disk end SD1 of the solid state drive through the first data distributor 25 and the second data distributor 26 of the backplane module 2 without causing the connection to the backplane module 2 and The local type solid state drive 5 without the second hard drive end SD2 often fails to communicate with the solid state drive when the backplane module 2 is only connected to either the first server 3 or the second server 4. 5 communication dilemma. Therefore, the purpose of enabling all servers in the dual-node server system to transmit information with dual-port transmission type and single-port transmission type solid state drives is achieved, and the purpose of the present invention can indeed be achieved.
