Description

Technical Field

[0001] The present application relates to the technical field of servers, and in particular to a method and system for lighting a back panel of a server. Background Art

[0002] At present, the backplane lighting solution is usually to parse the serial general purpose input / output (SGPIO) signals transmitted by the motherboard, disk array card or network card through a complex programmable logic device (CPLD) to perform corresponding lighting operations; however, in the case of two-port backplane cascade and one interface on the motherboard, both two-port backplanes will receive the same group of upstream SGPIO lighting signals. At this time, the two backplanes cannot distinguish which backplane's hard disk is to be lit by the lighting information of the SGPIO signal.

[0003] In order to allow the two backplanes to distinguish which hard disk the lighting information of a set of SGPIO signals is for, the relevant technology is to design a dip switch on the backplane, and manually set the dip switch according to the corresponding position of the backplane when assembling the whole machine, so that the logic elements on the backplane can distinguish the two backplanes according to different dip switches, thereby realizing the function that the two backplanes respectively use the lighting information of the first two hard disks and the lighting information of the last two hard disks of a set of SGPIO lighting signals.

[0004] The existing manual dialing method is highly dependent on the accuracy of the assembly workers' work. It is necessary to manually identify the lighting mode of each two-port backplane in the server, manually adjust the position of the dial switch or burn the dial information into the logic element. This production mode is extremely wasteful of manpower in the large-scale server production process, affecting the server production efficiency. At the same time, there is a risk of incorrect dialing information and the reliability of dialing is insufficient. Summary of the invention

[0075] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0076] It should be noted that, unless the context clearly requires otherwise, words such as “include”, “including” and similar words throughout the specification and claims should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is “including but not limited to”.

[0077] Furthermore, in the description of the present application, unless otherwise specified, “plurality” means two or more.

[0078] In today's digital age, servers are not only warehouses for data storage, but also the heart of business operations, supporting every link from daily business to complex calculations, and are an indispensable technical pillar for modern enterprises. In the sophisticated architecture of the server, the backplane is responsible for connecting to and managing external hard disks in the server, and is a key board to ensure high-speed and stable data transmission. During server operation, the backplane will detect various states of hard disk operation. In addition to transmitting signal data to the motherboard for analysis, it also has the function of indicating the hard disk status to the user through the LED light on the backplane board.

[0079] At the same time, in order to streamline the backplane space and prevent users from accidentally touching the dip switches and causing the dip switches to change, many existing backplane designs have eliminated the dip switches and instead use instructions to perform dip operations on the logic elements inside before assembling the entire machine. The dip codes are written into the registers inside the logic elements, ensuring the stability of the dip switches inside the backplane.

[0080] Embodiment 1

[0081] The present application embodiment provides a server backplane lighting method, such as Figure 1 , 2 As shown in , 3, the method is applied to a server backplane lighting system, the system includes a mainboard, a circuit board and several backplanes, the mainboard includes a signal circuit card, a controller, each backplane includes a logic element and several hard disks, the controller is connected to the circuit board, the circuit board is respectively connected to the logic element of each backplane, the signal circuit card is respectively connected to the logic element of each backplane, the circuit board includes several extended integrated circuits, the extended integrated circuits correspond to the backplanes one by one, the method includes:

[0082] Acquiring the dial code information of a plurality of extended integrated circuits in the circuit board through the controller;

[0083] The controller sends the dial code information of the extended integrated circuit in the circuit board to the logic element of the corresponding backplane;

[0084] The logic element of each backplane receives the serial input and output signals sent by the signal circuit card;

[0085] Analyze the serial input and output signals according to the source type of the signal circuit card, the status of the serial input and output signals and the dial code information of several extended integrated circuits to obtain the lighting information of several hard disks corresponding to each backplane;

[0086] The corresponding server backplane is lit according to the lighting information of the several hard disks corresponding to each backplane.

[0087] Specifically, the present application proposes a new type of cable device from the hardware level, in which a small circuit board PCB is integrated at the end of the backplane I2C cable close to the mainboard, and the circuit board has two four-channel IO expansion integrated circuits (Expanders) built in. The automatic dialing function is realized by recording the hard disk light dialing information in the expansion integrated circuit and reading the dialing information through the I2C link and transmitting it to the logic element CPLD, while the circuit board is powered by the mainboard;

[0088] The two cascaded backplanes in the server are usually connected to the same I2C Header of the motherboard. The I2C link is transmitted to the I2C (integrated circuit bus) Switch on the motherboard through the baseboard management controller (BMC). Then, two different channels of the I2C switch generate two I2C signals to an I2CHeader on the motherboard, which are then connected to the two backplanes through a Y-type cable to transmit the I2C information. Therefore, although the two IO expansion integrated circuits in the cable integrated PCB are connected to the same I2C Header, the actually connected I2C links are distinguished, so the addresses of the two IO Expander integrated circuits can be set to be consistent without special adaptation. Each IO Expander is mounted on the same I2C link with the corresponding backplane.

[0089] The beneficial effects of the technical solution provided by the embodiment of the present application are:

[0090] This application optimizes the lighting solution of the server backplane, solves the problem of low efficiency of manual dialing lighting during large-scale server production, and ensures the accuracy of the dialing information.

[0091] The technical solution provided in the embodiment of the present application provides a new type of cable device and line topology, which optimizes the lighting solution of the cascaded backplane. At the same time, due to the different lengths of the bit stream string of a group of lighting signals caused by different upstream devices, the backplane can also be adapted to a variety of lighting situations.

[0092] The technical solution provided in the embodiment of the present application realizes the automatic dialing function by using a new cable device, thereby solving the problem of low efficiency of manual dialing in the production process of large-scale servers and ensuring the accuracy of dialing information; by deleting the traditional dialing switch, the board design is streamlined, and the user is prevented from accidentally touching the switch and affecting the dialing; by storing the dialing information under various configurations in the IO expansion integrated circuit, the new cable can be adapted to various lighting usage scenarios and has high versatility.

[0093] Embodiment 2

[0094] The present application embodiment provides a server backplane lighting method, such as Figure 4 As shown, the method is applied to a server backplane lighting system, the system includes a mainboard, a circuit board and several backplanes, the mainboard includes a signal circuit card and a controller, each backplane includes a logic element and several hard disks, the controller is connected to the circuit board, the circuit board is respectively connected to the logic element of each backplane, the signal circuit card is respectively connected to the logic element of each backplane, the circuit board includes several extended integrated circuits, the extended integrated circuits correspond to the backplanes one by one, and the method includes:

[0095] Step S01, obtaining the dial code information of a plurality of extended integrated circuits in the circuit board through the controller;

[0096] The controller sends the dial code information of the extended integrated circuit in the circuit board to the logic element of the corresponding backplane;

[0097] The logic element of each backplane receives the serial input and output signals sent by the signal circuit card;

[0098] Specifically, the cable PCB device is connected to the I2C Header corresponding to the mainboard, and the other two ends are respectively connected to the corresponding backplane, and the SGPIO signal is sent to the corresponding backplane by connecting the Slimline connector cable and the power cable.

[0099] The mainboard controller BMC reads the dial code information of the IO Expander in the cable device PCB through I2C polling, and transmits the 4-bit dial code information of the expansion integrated circuit to the corresponding backplane logic element CPLD on the same I2C link. The two backplane CPLDs will receive the dial code information transmitted by the BMC in turn.

[0100] Step S02, setting a configuration table of signal lighting information corresponding to the first backplane and extended integrated circuit dial information corresponding to the first backplane, and setting the configuration table of signal lighting information corresponding to the first backplane and extended integrated circuit dial information corresponding to the first backplane as a first configuration table;

[0101] A configuration table of the signal lighting information corresponding to the second backplane and the extended integrated circuit dialing information corresponding to the second backplane is set, and the configuration table of the signal lighting information corresponding to the second backplane and the extended integrated circuit dialing information corresponding to the second backplane is set as the second configuration table.

[0102] Specifically, the configuration of each channel on the IO expansion integrated circuit corresponding to the first backplane is shown in the following Table 1:

[0103]

[0104] Table 1: IO channel configuration table of IO Expander integrated circuit corresponding to the first backplane The configuration of each channel on the IO expansion integrated circuit corresponding to the second backplane is shown in Table 2 below:

[0105]

[0106] Table 2: IO channel configuration table of IO Expander integrated circuit corresponding to the second backplane

[0107] Step S03, analyzing the serial input / output signal according to the source type of the signal circuit card, the state of the serial input / output signal and the dial code information of several expansion integrated circuits, and obtaining the lighting information of several hard disks corresponding to each backplane.

[0108] Specifically, the IO Expander integrated circuit inside the cable integrated PCB is responsible for recording the cascade backplane lighting dial code information, and represents the dial code information in different situations by pulling up and down the IO channel. The four-channel IO Expander integrated circuit is sufficient to adapt to the two situations with different SGPIO signal bit stream string lengths. When the upstream SGPIO signal comes from the motherboard or disk array Raid card, a set of SGPIO signals usually contains 12 bits of lighting information, and when the upstream SGPIO signal comes from devices such as IOH card (network card issued by Indosat Ooredoo Hutchison), a set of SGPIO signals usually contains 24 bits of lighting information. At the same time, every 3 bits of lighting information corresponds to a hard disk.

[0109] It is understandable that the backplane uses the SGPIO ADDR signal to distinguish whether the backplane corresponds to a set of SGPIO signal first 12-bit lighting information or the last 12-bit lighting information; usually at the source of the SGPIO signal, the SGPIO ADDR signal will be pulled down to indicate that the backplane corresponds to the first 12-bit lighting information, and the SGPIO ADDR signal will be pulled up to indicate that the backplane corresponds to the last 12-bit lighting information. The signal is transmitted to the backplane logic element CPLD through the Slimline connector. After parsing, the configuration of the backplane in the system can be obtained, and the dial code information can be used according to different configurations to ultimately ensure the correct lighting behavior.

[0110] When the motherboard is powered on, the Slimline connector transmits the SGPIO ADDR signal to the backplane CPLD. The backplane CPLD parses the signal according to the signal status and knows whether the cascaded backplane corresponds to the first 12-bit lighting information or the second 12-bit lighting signal.

[0111] That is, the backplane CPLD determines whether to use the first 2 bits or the last 2 bits of the 4-bit dial code information by parsing the SGPIO ADDR signal.

[0112] This application proposes a new type of cable device and a cascade backplane lighting solution, which can help cascade two backplanes to achieve intelligent dialing and lighting, thereby ensuring the intelligent assembly of the server and the automation of dialing.

[0113] Step S03 also includes:

[0114] Step S031, in response to the signal circuit card being a mainboard card or a disk array card, determining that the state of the serial input / output signal of the signal circuit card is a pull-down mode, and determining the first signal lighting information corresponding to the first backplane and the first signal lighting information corresponding to the second backplane according to the state of the serial input / output signal of the signal circuit card;

[0115] Determine the first dial code information of the extended integrated circuit corresponding to the first backplane according to the first configuration table and the first signal lighting information corresponding to the first backplane;

[0116] Determine the second dial code information of the extended integrated circuit corresponding to the second backplane according to the second configuration table and the first signal lighting information corresponding to the second backplane;

[0117] Determine the first lighting information of the hard disk corresponding to the first backplane (the lighting information of the 0th to 5th positions of the first 12-bit SGPIO signal) according to the first dial code information of the extended integrated circuit corresponding to the first backplane;

[0118] The second lighting information of the hard disk corresponding to the second backplane (the 6th to 11th lighting information of the first 12-bit SGPIO signal) is determined according to the second dial code information of the extended integrated circuit corresponding to the second backplane.

[0119] Specifically, in response to the signal circuit card being a mainboard card or a disk array card, the corresponding SGPIO signal state has only a pull-down mode, then according to the first configuration table, the first backplane parsing dial information 00 corresponds to the use of the 0th to 5th bit light information of the first 12-bit SGPIO signal; according to the second configuration table, the second backplane parsing dial information 01 corresponds to the use of the 6th to 11th bit light information of the first 12-bit SGPIO signal.

[0120] Step S032, in response to the signal circuit card being a network card, the signal state of the signal circuit card is judged, and the serial input and output signals are parsed according to the signal state judgment result of the signal circuit card and the extended integrated circuit dial code information corresponding to the backplane, so as to obtain the lighting information of several hard disks corresponding to each backplane;

[0127] In response to the state of the serial input / output signal of the signal circuit card being in the pull-up mode, determining the second signal lighting information corresponding to the first backplane and the second signal lighting information corresponding to the second backplane according to the state of the serial input / output signal of the signal circuit card (the backplane corresponds to the last 12 bits of lighting information);

[0139] The first hard disk and the second hard disk of the second backplane are respectively lit up through the fourth lighting information of the hard disk corresponding to the second backplane.

[0140] Specifically, the logic element CPLD reads the corresponding hard disk lighting information according to the dial code information, analyzes the SGPIO lighting signal and manages the hard disk lighting.

[0141] If the SGPIO ADDR signal is pulled down, the first backplane parses the dial information 00, corresponding to the use of the 0th to 5th position lighting information of the first 12-bit SGPIO signal, the first three digits of the 0th to 5th position lighting information turn on the first hard disk of the first backplane, and the last three digits of the 0th to 5th position lighting information turn on the second hard disk of the first backplane; the second backplane parses the dial information 01, corresponding to the use of the 6th to 11th position lighting information of the first 12-bit SGPIO signal, the first three digits of the 6th to 11th position lighting information turn on the first hard disk of the second backplane, and the last three digits of the 6th to 11th position lighting information turn on the second hard disk of the second backplane.

[0142] If the SGPIO ADDR signal is pulled up, the first backplane parses the dial code information 10, which corresponds to the 0th to 5th bit lighting information of the last 12-bit SGPIO signal. The first three digits of the 0th to 5th bit lighting information light up the first hard disk of the first backplane, and the last three digits of the 0th to 5th bit lighting information light up the second hard disk of the first backplane; the second backplane parses the dial code information 11, which corresponds to the 6th to 11th bit lighting information of the last 12-bit SGPIO signal. The first three digits of the 6th to 11th bit lighting information light up the first hard disk of the second backplane, and the last three digits of the 6th to 11th bit lighting information light up the second hard disk of the second backplane.

[0144] The switch is connected between the controller and the circuit board;

[0145] The switch is connected to each expansion integrated circuit of the circuit board through a serial communication bus channel whose number corresponds to the expansion integrated circuit of the circuit board.

[0146] Step S06, when one of the hard disks of the backplane is lit, the presence indicator light corresponding to the hard disk is lit;

[0147] When a fault occurs on one of the hard disks of the backplane, the positioning indicator light and the fault indicator light corresponding to the hard disk are turned on, and the hard disk fault of the backplane is detected;

[0148] The detecting of a hard disk failure of the backplane includes:

[0149] Check whether the connection cable between the faulty hard disk and the backplane is secure;

[0150] Check the health of hard disks through hardware monitoring tools;
