Description

Server startup method and device, storage medium and electronic device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on February 27, 2024, with application number 202410216549.8 and entitled “Server startup method and device, storage medium and electronic device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of computers, and in particular to a server startup method and device, a storage medium, and an electronic device. Background Art

[0004] In the related art, it is usually possible to install an operating system on a server by launching the PXE (Preboot eXecution Environment) function through a network port. However, a server typically includes multiple network ports, and multiple network cards may be connected to multiple network ports at the same time. Currently, the server's network port PXE function defaults to launching in the order identified during startup. Regardless of the type of network card currently connected to the network port, the first recognized network card will be used to execute the PXE function to install the operating system on the server.

[0005] In this case, because different network cards using PXE may install different operating systems on the server, and the currently connected network port is not the first network port or a specific network port such as the one of a smart network card, the first network card identified using PXE may install an operating system that is not the currently required system, or the location of the pre-installed system may not be the currently expected location, making it incompatible with other network cards. For example, if the first network card identified is an OCP (Open Compute Project) network card, the system installed with PXE enabled on the OCP network card will not support the smart network card used on the server at the same time.

[0081] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0082] The method embodiments provided in the embodiments of the present application can be executed in a server device or a similar computing device. Taking operation on a server device as an example, FIG1 is a hardware structure block diagram of a server device of a method for starting a server in an embodiment of the present application. As shown in FIG1 , the server device may include one or more (only one is shown in FIG1 ) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU (Microcontroller Unit) or a programmable logic device FPGA (Field Programmable Gate Array)) and a memory 104 for storing data, wherein the above-mentioned server device may also include a transmission device 106 and an input and output device 108 for communication functions. It will be understood by those skilled in the art that the structure shown in FIG1 is only for illustration, and it does not limit the structure of the above-mentioned server device. For example, the server device may also include more or fewer components than those shown in FIG1 , or have a configuration different from that shown in FIG1 .

[0083] The memory 104 can be used to store computer-readable instructions, for example, software programs and modules of application software, such as computer-readable instructions corresponding to the startup method of the server in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer-readable instructions stored in the memory 104, that is, implementing the above-mentioned method. The memory 104 may include a high-speed random access memory, and may also include a non-transitory memory, such as one or more magnetic storage devices, flash memory, or other non-transitory solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the server device via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

In some examples, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In some examples, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0085] In this embodiment, a method for starting a server is provided. FIG2 is a flow chart of a method for starting a server according to an embodiment of the present application. As shown in FIG2 , the method for starting a server is applied to a basic input and output system installed in the server. A network device interface group is deployed on the server. The network device interface in the network device interface group is used to connect to a network device. The network device has a pre-boot execution environment control function. The process of the method includes the following steps:

[0086] Step S12, in response to determining that the peripheral component interconnection standard enumeration phase has been reached, detecting presence information of the network device interfaces in the network device interface group, wherein the presence information is used to indicate whether the corresponding network device interface is connected to a network device;

[0087] In some embodiments, FIG3 is a schematic diagram of a server according to an embodiment of the present application. As shown in FIG3 , the entire server includes a server motherboard and a connected network card, wherein the network card is connected to an expansion slot (Slot0 to Slot3, for example only, the number of expansion slots and the connected network card can be adjusted according to actual needs), the expansion slot is connected to CPU (Central Processing Unit) 0 via a PCI (Peripheral Component Interconnect) bus, CPU0 is connected to BIOS via CPU1, CPU0 is connected to CPU1 via a UPI (Ultra Path Interconnect) bus, and CPU1 is connected to BIOS (Basic Input Output System) via an SPI / LPI (Serial Peripheral Interface / Low Power Interface) bus. The server startup method is applied to the basic input and output system installed in the server, and the basic input and output system can be, but is not limited to, the BIOS in FIG3 .

[0088] In some embodiments, the network device interface may be, but is not limited to, a network port, and the network device may be, but is not limited to, a network card. As shown in FIG3 , when the network device is a network card, the network device may be, but is not limited to, a Smart NIC, an OCP NIC (i.e., an Open Compute Project NIC), or a PCI standard NIC (i.e., a Peripheral Component Interconnect NIC). Smart NICs, Open Compute Project NICs, and Peripheral Component Interconnect NICs all have a pre-boot execution environment control function.

[0089] In some embodiments, the pre-boot execution environment control function may be, but is not limited to, a PXE (Preboot eXecution Environment) function.

[0090] Step S14, disabling a pre-boot execution environment control function of a reference network device corresponding to a plurality of reference network device interfaces in the network device interface group, wherein the reference network device interface is a network device interface for indicating a network device interface connected to the reference network device;

[0091] In some embodiments, taking Figure 3 as an example, a smart network card, an OCP network card, and a PCI network card are connected to the network device interface group of the server. The smart network card, the OCP network card, and the PCI network card are all reference network devices, and the pre-boot execution environment control function of the smart network card, the OCP network card, and the PCI network card is turned off. This application uses the network devices deployed on the server as smart network cards, OCP network cards, and PCI network cards as examples to illustrate the server startup method. The network devices can also be host bus adapter HBA (Host Bus Adapter) network cards and host channel adapter HCA (Host Channel Adaptor) network cards. Because each type of network card has different functions and speeds, different network cards configured on the server have different business requirements. For example, smart network cards focus on virtual cloud services, OCP network cards focus on network data exchange, and PCI interface network cards focus on traditional information transmission. All physical network cards perform network information transmission, but in a server configured with a smart network card, it is necessary to use the PXE function on the smart network card to start and install the cloud system. If the network without a smart network card uses the PXE function to start and install the system, the system will be installed to the local storage hard disk and the cloud system cannot be started. The server startup method proposed in this application can overcome the problem of low compatibility between the pre-boot execution environment control function enabled during the server startup process and the network equipment in the server.

[0092] Step S16: Filtering a target network device from the multiple reference network devices based on the reference device types of the reference network devices correspondingly connected to the multiple reference network device interfaces, wherein the target network device is a network device having a target startup priority corresponding to the target device type thereof being the highest among the multiple reference network devices, the device type of the network device being used to indicate a device version of the network device, and the pre-boot execution environment control functions of the device versions being downwardly compatible, and each device type being set to a corresponding startup priority proportional to the indicated device version;

[0093] In some embodiments, the device type of a network device is used to indicate the device version of the network device. The pre-boot execution environment control function of the device versions from high to low is backward compatible. Taking the smart network card, OCP network card and PCI network card as examples, the device versions from high to low are: smart network card, OCP network card and PCI network card. The pre-boot execution environment control function of the smart network card is compatible with the normal operation of the smart network card, OCP network card and PCI network card; the pre-boot execution environment control function of the OCP network card is compatible with the normal operation of the OCP network card and PCI network card, but not compatible with the normal operation of the smart network card; the pre-boot execution environment control function of the PCI network card is only compatible with the normal operation of the PCI network card, but not compatible with the normal operation of the smart network card and OCP network card. Each device type is set to a corresponding boot priority that is proportional to the indicated device version. The boot priority from high to low is: smart network card, OCP network card and PCI network card.

[0094] In some embodiments, the pre-boot execution environment control function of the smart network card can be compatible with the normal operation of the smart network card, OCP network card and PCI network card. It can be understood that when the smart network card turns on the pre-boot execution environment control function, the operating system installed in the server can support the normal operation of the smart network card, OCP network card and PCI network card.

[0095] The pre-boot execution environment control function of the OCP network card is compatible with the normal operation of the OCP network card and the PCI network card, but is not compatible with the normal operation of the Smart NIC. This means that when the pre-boot execution environment control function is enabled on the OCP network card, the operating system installed on the server cannot support the normal operation of the Smart NIC, but can support the normal operation of the OCP network card and the PCI network card.

[0096] The pre-boot execution environment control function of the PCI network card is only compatible with the normal operation of the PCI network card, and is not compatible with the normal operation of the Smart NIC and OCP network card. It can be understood that when the pre-boot execution environment control function of the PCI network card is enabled, the operating system installed in the server cannot support the normal operation of the Smart NIC and OCP network card, but can support the normal operation of the PCI network card.

[0097] It is worth noting that when the pre-boot execution environment control function is enabled on the Smart NIC, the operating system installed on the server is the cloud system, which is installed in the Smart NIC. When the pre-boot execution environment control function is enabled on the OCP NIC and PCI NIC, the operating system installed on the server is the local system, which is installed on the local storage hard disk.

[0098] Step S18: starting the pre-boot execution environment control function of the target network device.

[0099] In an embodiment of the present application, a server startup method is proposed, which is applied to a basic input and output system installed in the server, wherein a network device interface group is deployed on the server, and the network device interfaces in the network device interface group are used to connect to network devices, and the network devices have a pre-start execution environment control function. In response to determining that the startup process of the server has executed to the peripheral component interconnection standard enumeration stage, the presence information of the network device interfaces in the network device interface group is detected to determine whether the corresponding network device interface is connected to the network device, and the pre-start execution environment control functions of the corresponding reference network devices on multiple reference network device interfaces in the network device interface group are turned off. The presence information of the reference network device interface is used to indicate the network device interface that is connected to the reference network device, thereby avoiding the situation similar to the related art in which the reference network device interface is directly started upon detecting that the network device interface is connected to the reference network device. The pre-start execution environment control function of the network device is used to prevent the low compatibility between the pre-start execution environment control function and the network device in the server. Furthermore, according to the reference device type of the reference network device correspondingly connected to the multiple reference network device interfaces, the target network device is screened from the multiple reference network devices, wherein the target network device is the network device with the highest target startup priority corresponding to the target device type among the multiple reference network devices. The device type of the network device is used to indicate the device version of the network device. The pre-start execution environment control function of the device version from high to low is downward compatible. Each device type is set to a corresponding startup priority proportional to the indicated device version; therefore, starting the pre-start execution environment control function of the target network device can ensure that the started pre-start execution environment control function is compatible with the current network device of the server. The above technical solution solves the problem of low compatibility between the pre-start execution environment control function turned on by the server during the startup process and the network device in the server in the related technology, and achieves the technical effect of improving the compatibility between the pre-start execution environment control function turned on by the server during the startup process and the network device in the server.

[0100] In some embodiments, in response to determining that the network device is a network card device, screening the target network device from the plurality of reference network devices according to the reference device types of the reference network devices correspondingly connected to the plurality of reference network device interfaces includes:

[0101] S21, identifying a device type of each reference network device among the multiple reference network devices until all reference network devices among the multiple reference network devices are identified, thereby obtaining multiple reference device types;

[0102] S22, in response to determining that the multiple reference device types include a Smart NIC type, determining a Smart NIC type network card device among the multiple reference device types as a target network device with the highest startup priority;

[0157] In some embodiments, in order to better understand the process of starting the above-mentioned server, the startup process of the above-mentioned server is described below in combination with the embodiments, but it is not used to limit the technical solutions of the embodiments of the present application.

[0158] In this embodiment, a method for starting a server is provided. FIG4 is a schematic diagram of a server startup process according to an embodiment of the present application. As shown in FIG4 , the method mainly includes the following steps:

[0159] Step S401: In response to determining that the server is started, the BIOS identifies and determines the type of network card in the PCI enumeration phase, and sets the presence information of the Smart NIC, OCP NIC, and PCI interface NIC.

[0160] Step S402: assigning initial values ​​(i.e., first network port parameters) to the identified network ports of each type of network card, creating a network card PXE function setting option (equivalent to a control option) for each network port, displaying it in the BIOS interface (Basic Input and Output System interface), and updating the network card boot classification group (equivalent to the target detection sorting);

[0161] Step S403: After the network card startup classification group is created, the network card type is confirmed through the device identification message of the network card type;

[0162] Step S404: In response to determining that the Smart NIC is present, the PXE function of the network port of the Smart NIC is enabled, and the PXE functions of the network ports of the remaining OCP NICs or PCI standard NICs are disabled. At the same time, the initial values ​​of the network ports are updated and the shutdown function is set. The BIOS interface displays the Smart NIC enabled and the PXE functions of the remaining network ports disabled.

[0163] Step S405: In response to determining that the Smart NIC does not exist and that both the OCP NIC and the standard PCI NIC are identified, the PXE function of the network port of the OCP NIC is enabled, and the PXE functions of the network ports of the remaining standard PCI NICs are disabled. At the same time, the initial values ​​of the network ports are updated and the shutdown function is set. The BIOS interface displays the OCP NIC enabled and the PXE functions of the remaining network ports disabled.

[0164] Step S406: In response to determining that the OCP network card does not exist and a standard PCI network card is identified, the PXE function of the network port of the identified PCI standard network card is enabled, and at the same time, the BIOS interface displays that the PXE function of the PCI standard network port is enabled;

[0165] Step S407: Step 4-6 is to automatically turn on or off the network port PXE function. Based on step 4-6, the network port can be manually turned on or off.

[0166] Figure 5 is a swimlane diagram of a server startup process according to an embodiment of the present application. As shown in Figure 5, the server startup process involves the server, BIOS and network port control. The server startup method is run through the BIOS, and the PXE function of the server network port is controlled to install the operating system in the server, thereby realizing the entire process from powering on the server to entering the operating system.

[0167] The server startup method proposed in this application designs a solution for turning off or on the network port function in combination with the type of network card used, that is, when the smart network card, OCP network card, and PCI standard network card are all configured in the server system, no matter which network port is recognized first, the network port PXE function of the smart network card is turned on, the network port PXE functions of the other network cards are turned off, and the above-mentioned PXE function is controlled as a control option in the BIOS interface; when there is no smart network card, and there are OCP network card and other standard PCI network cards, no matter which network port is recognized first, the network port PXE function of the OCP network card is turned on, the network port PXE functions of the other network cards are turned off and the PXE functions are controlled in the BIOS interface. The IOS interface controls the above PXE function as a control option. When there is no smart network card or OCP network card and a standard PCI network card is present, the PXE function of the network port of the first identified network card is enabled, and the PXE functions of the network ports of the remaining network cards are disabled, and the above PXE function is controlled as a control option in the BIOS interface. If it is necessary to support the requirement of enabling the PXE function when both the smart network card and the OCP network card are in place, the PXE function of the smart network card and the OCP network card is enabled in the same way, the PXE function of the network port of the remaining network cards is disabled, and the above PXE function is controlled as a control option in the BIOS interface.

[0168] The present application relates to a method for dynamically controlling the PXE booting of a network port. In response to determining that a server is booting, the PCI enumeration stage of the BIOS identifies the type of network card in the PCI device, such as the smart network card, OCP network card, and standard PCI network card in place information. According to the identification result, the PXE of the network card is enabled by default and the BIOS interface control options of each network port are innovated. At the same time, according to the message type of the PCI device, the network card types such as the smart network card, OCP network card, and standard network card identified in the booting process are identified. According to the priority of the network card device, the network port PXE function is set for each identified network card. At the same time, during the BIOS booting process, it supports manual special settings for the activation of the network port PXE function for use in specific environments. In the solution proposed in the present application, in response to determining PCI enumeration, the BIOS sets and updates the BIOS interface display options according to the device presence information and the expected priority of the network port PXE function activation. When special needs arise, the network port PXE function can be set through the BIOS interface to ignore the need for the BIOS to automatically control the activation of the PXE function.

[0169] In the solution proposed in this application, when the BIOS is started, the presence information of the smart network card, OCP network card, and PCI standard network card is identified during the PCI enumeration process. At the same time, BIOS options are created for the network ports of each type of identified network card and enabled by default. Different BIOS option setting functions are set according to the device message type to confirm what type of network card exists and different requirements for enabling the PXE function of different network card types. At the same time, it supports the need to manually set special network port functions to be turned on or off. It supports both automatic identification of the PXE function started by the network card and modification of the PXE setting function for special needs. The solution proposed in this application is applicable to server products of any architecture.

[0170] The solution proposed in this application has strong replicability and scalability. By combining the server startup, the BIOS identifies the presence information of the smart network card, OCP network card, and standard PCI network card during PCI enumeration. At the same time, the PXE function of the network port is enabled and a control option for the PXE function of each network port is added and enabled in the BIOS interface. The current network card type is confirmed by the message type of the network card device. In response to determining that the current network card type is a smart network card, the PXE function of the smart network card is enabled, and the PXE functions of other non-smart network cards are turned off. In response to determining that the smart network card is not identified and the OCP network card is identified, the PXE function of the OCP network card is used and the PXE functions of other non-OCP network cards are turned off. In response to determining that the smart network card and the OCP network card are not identified, the PXE function of all network ports is enabled. At the same time, the PXE function of the corresponding network port is set and displayed accordingly in the BIOS interface. When any PXE function that does not meet the above expectations needs to be modified manually, the PXE function of the specific network port can be enabled in the BIOS interface, and the automatic control of the PXE function can be ignored. This solution is convenient and easy for R&D and operation and maintenance personnel to adjust according to actual business needs. It supports any architecture server product and has strong versatility and high applicability.

Based on this understanding, the technical solution of the present application, or the part that contributes to the relevant technology, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
