At present, in a server (also referred to as a "server node"), a high-speed cable is often used to connect different hardware boards so as to transmit high-speed signals such as a high-speed serial computer extended bus (PCIE) standard, a serial attached Small Computer System Interface (SCSI) and the like across the boards. A Baseboard Management Controller (BMC) in the server needs to accurately detect the presence, insertion errors, and the like of the high-speed cable. However, in a multi-child server node, there are multiple identical server systems, and these multiple identical server systems often have identical components, and if the high-speed cable is connected across systems in reverse, the bmc cannot detect them, which will seriously affect the service on the client side.

Since the hardware system being tested is powered up, each cable should have signal transmission in the event that the cable is not connected incorrectly therein. Therefore, when no signal is transmitted in a certain cable, the cable is connected incorrectly.

In a possible implementation manner, detecting whether a cable connection error exists in an ith hardware system according to a power-on signal of the ith hardware system and a signal transmitted by each cable in the ith hardware system specifically includes: aiming at any cable in the ith hardware system, under the condition of acquiring a power-on signal and acquiring a signal transmitted by any cable, determining that any cable is not connected wrongly; and determining that any cable is connected wrongly when the power-on signal is acquired and the signal transmitted by any cable is not acquired.

By way of example, FIG. 1 illustrates a cable detection system. As shown in fig. 1, the cable detection system 100 includes: a detection device 110 and a server 120 comprising n (n ≧ 2) hardware systems. The detection device 110 and the server 120 may, but are not limited to, establish a connection through a network card; of course, the connection may be established in other manners, which may be determined according to actual situations. For the power supply mode of the detection device 110 and the server 120, both can use separate power sources to supply power.
The detection device 110 is used to detect whether a cable in the server 120 is connected in error. The detection device 110 may control the server 120 through, but not limited to, an Intelligent Platform Management Interface (IPMI) command. For example, a hardware system in the control server 120 is powered on or off. In addition, the detection apparatus 110 may also read the cable detection results in each hardware system in the server 120 through the IPMI instruction, and output the detection results. For example, the detection device 110 may sequentially control each of the n hardware systems in the server 120 to power on or power off.
Each hardware system in the server 120 is a system that can be independent. The hardware contained in each hardware system may be the same, or partially the same, etc. The hardware in each hardware system may be connected to each other through, but not limited to, a cable (such as a high-speed cable, etc.), and may also be connected to each other through a connector. Illustratively, the hardware system may be an X86 system. Each hardware system may include, for example, a motherboard, a Central Processing Unit (CPU), a disk array (RAID), a Complex Programmable Logic Device (CPLD), a Baseboard Management Controller (BMC), and the like.
The server 120 is provided with a signal detector 121. The signal detector 121 may be hard-wired to hardware downstream of the respective cables, such as by a connector or the like. Meanwhile, the signal detector 121 may be hard-wired to hardware (e.g., BMC or CPLD) in each hardware system for transmitting power-on and power-off states of the corresponding hardware system. The signal detector 121 may be disposed separately, or may be integrated into other hardware (such as a hard disk backplane, a board for managing fans, etc.). Illustratively, the signal detector 121 may be, but is not limited to, a CPLD. For example, the connection mode of two pieces of hardware connected by a cable can be called as a soft connection.
The detection device 110 may control each hardware system in the server 120 to power up or power down, respectively. After the user issues the detection instruction through the detection device 110, the detection device 110 may first control only one hardware system to be powered on, but after the detection of the hardware system is completed, may control the hardware system to be powered off, and control another hardware system to be powered on, and the process is repeated until the detection of all the hardware systems is completed.
In the detection process, after a certain hardware system in the server 120 is powered on, the hardware in the hardware system for transmitting the power-on and power-off states of the system may send a signal that the system is powered on to the signal detector 121 through two rows of serial buses (I2C) or an SGPIO (serial bus input/output) bus. In addition, after the hardware system is powered on, the contained hardware is also powered on, and at this time, signals are transmitted between the hardware connected through the cable. When a signal on a certain cable is transmitted to hardware downstream of the cable, the signal may be simultaneously transmitted to the signal detector 121. If the signal detector 121 obtains both the signal that the hardware system is powered on and the signal transmitted by each cable in the hardware system, it indicates that no connection error exists in the line in the hardware system. If the signal detector 121 acquires a signal that the hardware system is powered on but does not acquire a signal transmitted by a certain cable, it indicates that the line is connected incorrectly, i.e. plugged in incorrectly. The signal detector 121 may transmit the detection result to the detection device 110 after completing the detection of the respective cables, so as to be presented to the user through the detection device 110. Illustratively, the signal detector 121 and the detection device 110 may be directly connected or indirectly connected. When the two are indirectly connected, the two can be connected through hardware in each hardware system for transmitting the power-on and power-off states of the corresponding system. In some embodiments, the signal detector 121 may transmit the detection result to the BMC in the hardware system. Thereafter, the detection device 110 may send an instruction to read the detection result to the CPU in the hardware system. The CPU may then communicate with the BMC and obtain the detection result and transmit the detection result to the detection device 110.
Next, a cable detection method provided in an embodiment of the present application is described based on the system shown in fig. 1.
Illustratively, FIG. 2 illustrates a cable detection method. As shown in fig. 2, the cable detection method may include the steps of:
s201, the detection device 110 obtains a detection instruction issued by a user.
In this embodiment, the detection device 110 may provide a visual interface. Through the interface, the user may issue a detection instruction to detect the cable in the server 120.
S202, the detection device 110 controls the ith hardware system in the server 120 to be powered on, where an initial value of i is 1.
In this embodiment, the detection device 110 may control the ith hardware system in the server 120 to be powered on, so as to detect the cable in the ith hardware system. Wherein the initial value of i is 1. For example, the detection device 110 may send a power-on instruction to the server 110 or the ith hardware system in the server 110, so that the server 120 controls the power-on of the ith hardware system. The server 120 may then control the ith hardware system to power up. When the ith hardware system is powered on, the ith hardware system is in a powered-on state. In addition, all the hardware systems in the server 120 except the ith hardware system are in a power-off state, that is, none of the hardware systems is powered on.
And S203, sending a signal for representing that the ith hardware system is powered on to the signal detector 121 in the ith hardware system.
S204, the signal detector 121 obtains signals transmitted by each cable in the ith hardware system.
S205, the signal detector 121 determines whether the cable in the ith hardware system is connected incorrectly based on the signal used for representing that the ith hardware system is powered on and the signals acquired by the signal used for representing the cable transmission.
In this embodiment, when the signal detector 121 acquires a signal indicating that the ith hardware system is powered on, it may determine that the ith hardware system is powered on. Therefore, it should acquire signals transmitted by the cables in the ith hardware system at this time. If the signal transmitted by a certain cable is not acquired, the connection error of the cable is indicated.
S206, the signal detector 121 sends a message containing a detection result of the cable in the ith hardware system to the detection device 110.
In this embodiment, after completing the detection of the cable in the ith hardware system, the signal detector 121 may send the detection result to the detection device 110. For example, the signal detector 121 may first send the detection result to the ith hardware system, for example, to the BMC in the ith hardware system, and then the ith hardware system sends the detection result to the detection device 110.
In some embodiments, the detection device 110 may issue a result reading instruction for reading the detection result to the server 120 or the ith hardware system in the server 120. After the result reading instruction is obtained by the server 120 or the ith hardware system in the server 120, the detection result may be transmitted to the detection device 110.
And S207, the detection device 110 controls the power-off of the ith hardware system.
In this embodiment, after the detection of the cable in the ith hardware system is completed, the hardware system may be controlled to power down.
S208, the detection device 110 determines whether i = i +1, and determines whether i is greater than n, where n is the number of hardware systems included in the server 120.
In this embodiment, after the detection of the cable in the ith hardware system is completed, another hardware system may be detected. At this time, i = i +1 may be controlled. Meanwhile, it is determined whether i is greater than n, which is the number of hardware systems included in the server 120. If i is greater than n, it indicates that the detection of the cables in all the hardware systems in the server 120 is completed, and at this time S209 may be executed. If i is less than or equal to n, it indicates that the detection of cables in all hardware systems in the server 120 is not completed, and at this time, the process may return to S202.
S209, the detection device 110 outputs a detection result.
In this embodiment, after completing the detection of the cables in all the hardware systems in the server 120, the detection device 110 may output a detection result. In some embodiments, the detection device 110 may also directly display the detection result every time the detection result of the cable in one hardware system is obtained, or may display the detection results after the detection result of the cable in a part of hardware systems is obtained, which may be determined according to actual situations, and is not limited herein.
Therefore, when the cables in the hardware systems in the server are detected, the cables in the hardware systems are detected independently, and other hardware systems are controlled to be powered off in the detection process, so that the interference of other hardware systems is avoided, the detection of the same cables among the same hardware systems is realized, and the problem that the same cables among the same hardware systems cannot be detected due to the connection error of the same cables is solved.
In some embodiments, the steps performed by a component in the server 120 in fig. 2 may also be understood as steps performed by the server 120.
In some embodiments, the process described in fig. 2 may be described as: the detection equipment acquires a detection instruction issued by a user. And responding to the detection instruction, and sequentially controlling each hardware system in the n hardware systems to be powered on by the detection equipment, wherein when one hardware system in the n hardware systems is in a powered-on state, other hardware systems in the n hardware systems are in a powered-off state. The server detects whether a cable connection error condition exists in the hardware system in the power-on state or not based on signals transmitted by each cable in the hardware system in the power-on state in the n hardware systems so as to obtain a detection result corresponding to the hardware system in the power-on state. The method comprises the steps that detection equipment obtains detection results corresponding to each hardware system in n hardware systems to obtain n detection results; and outputting n detection results.
In addition, the server detects whether a cable connection error exists in the hardware system in the powered-on state based on signals transmitted by each cable in the hardware system in the powered-on state in the n hardware systems, which may be specifically described as: for any cable in the hardware system in the power-on state, determining that any cable is not connected wrongly under the condition that the server acquires a signal transmitted by any cable; and determining that any cable is connected incorrectly under the condition that the server does not acquire the signal transmitted by any cable.
For ease of understanding, the following description will be made by taking three hardware systems included in the server 120 as an example.
Illustratively, as shown in fig. 3, each of the hardware systems 1, 2, and 3 includes a CPU, hardware a, hardware B, and BMC. For the hardware system 1, the CPU is hard-wired to the hardware a therein, the hardware a is soft-wired to the hardware B therein, and both the hardware B and the BMC are hard-wired to the signal detector 121 in the server 120. For the hardware system 2, the CPU is hard-wired to the hardware a therein, the hardware a is soft-wired to the hardware B therein, and both the hardware B and the BMC are hard-wired to the signal detector 121 in the server 120. For the hardware system 3, the CPU is hard-wired to the hardware a therein, the hardware a is soft-wired to the hardware B in the hardware system 2 (i.e. the cable is misconnected here), and the hardware B and the BMC are hard-wired to the signal detector 121 in the server 120. Wherein the double-arrowed lines in fig. 3 represent hard connections and the curves without arrows represent soft connections.
When detecting the cable in the server 120, the cable in the hardware system 1 may be detected first, then the cable in the hardware system 2 may be detected, and finally the cable in the hardware system 3 may be detected. Specifically, the hardware system 1 may be controlled to be powered on, and the hardware systems 2 and 3 may be controlled to be powered off at the same time, that is, only the hardware system to be detected is powered on. After the hardware system 1 is powered on, the BMC in the hardware system 1 may transmit a signal to the signal detector 121 that the system is powered on. Meanwhile, the signal transmitted by the cable between the hardware a and the hardware B is transmitted from the hardware B to the signal detector 121. Since the BMC in the hardware system 1 is hard-wired to the signal detector 121, a fault does not occur between the BMC and the signal detector 121, and the signal detector 121 may receive a signal transmitted by the BMC at a high probability; since the hardware a and the hardware B are connected by a soft connection, a cable may be connected by a wrong connection. When the cable between the hardware a and the hardware B is in error, the signal detector 121 cannot acquire the signal transmitted by the hardware B. Therefore, if the signal detector 121 acquires the signal transmitted by the BMC in the hardware system 1 and simultaneously acquires the signal transmitted by the cable between the hardware a and the hardware B, it indicates that the cable between the hardware a and the hardware B is not connected in error. After completing the detection of the cable between the hardware a and the hardware B, the signal detector 121 may transmit the detection result to the BMC in the hardware system 1, and the BMC may transmit the detection result to the detection device.
Further, the cable in the hardware system 2 may be detected. At this time, the hardware systems 1 and 3 can be controlled to be powered off and the hardware system 2 can be controlled to be powered on simultaneously. For the detection process of the cable in the hardware system 2, reference may be made to the detection process of the cable in the hardware system 1, which is not described herein again.
After the detection of the cable in the hardware system 2 is completed, the detection of the cable in the hardware system 3 may be performed. At this time, the hardware systems 1 and 2 can be controlled to be powered off and the hardware system 3 can be controlled to be powered on simultaneously. Since the cable between the hardware a and the hardware B in the hardware system 3 is in a wrong connection and the hardware system 2 is in a power-off state, the signal detector 121 cannot acquire the signal transmitted by the cable, but only can acquire the signal transmitted by the BMC in the hardware system 3 that the system is powered on. Therefore, the signal detector 121 may determine that the cable in the hardware system 3 is connected in error, and send the detection result to the detection device via the BMC in the hardware system 3.
