[0054] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0055] The embodiments of the present application can be applied to scenarios where the resources of a server are expanded. Taking the cloud computing scenario as an example, in order to better provide computing and other services, the server can be connected to an external board to access external devices, which include a network card, a storage device, and the like. Among them, the network card is also called a network adapter or a network interface card. Based on the network card, the hardware device can be connected to the network and perform network communication. The storage device is a device for data storage, such as a disk, a hard disk, and the like. Among them, the disk refers to a memory that uses magnetic recording technology to store data. By inserting a network card on the board, the bandwidth resources of the server can be expanded, and by inserting a storage device on the board, the storage resources of the server can be expanded, thereby improving the performance of the server.

[0056] Among them, such as Figure 1 As shown, the system includes a server 102 and a board 104 , and the server and the board are connected via a PCIe (Peripheral Component Interface Express, a high-speed serial computer expansion bus standard) bus. PCIe is a high-speed serial bus.

[0057] The server includes an operating system (OS) and a basic input / output system (BIOS). The OS is a built-in program that coordinates the server's hardware and interacts with users. The BIOS is a set of programs hard-coded into a read-only memory (ROM) chip on the server's motherboard. The BIOS stores the server's basic input / output (BITO) programs, post-boot self-test routines, and system startup routines. The BIOS also provides system parameters to the operating system. Changes to the system hardware are hidden from the BIOS, serving as a bridge between the hardware and the operating system.

[0058] The board includes a VSEC (Vendor-Specific Extended Capability) module. VSEC is an extended capability provided to vendors as specified in the PCI specification and can be customized by the vendor.

[0059] The board can be plugged into one or more external devices 106, such as external devices 1061, 1062, ..., 106n, where n is a positive integer greater than 0. The type, quantity, and topology of the external devices connected to the board are determined by the board based on the server's expansion capabilities when the server is started.

[0060] Reference Figure 2 , showing an interactive schematic diagram of an embodiment of a server resource expansion method of the present application.

[0061] Step 202: When the server starts, it obtains the storage address of the hardware description information and notifies the board of the storage address of the hardware description information.

[0062] When the server is started, the BIOS of the server generates hardware description information based on the server system resources. The hardware description information is used to describe the hardware data of the system.

[0063] In the embodiments of the present application, the hardware description information may be data in a DSDT (Differentiated System Description Table). The DSDT contains information about all different devices except the basic system. While the basic system is the same for each device, the DSDT describes the system information for each device. The DSDT is a table in the Advanced Configuration and Power Management Interface (ACPI), an interface used by operating systems and applications to manage all power management functions.

[0064] In an optional embodiment of the present application, when the server starts, the storage address of the hardware description information is obtained, including: when the server starts, (the server BIOS) generates the hardware description information based on the system resources of the server; loads the data of the expansion memory from the board, such as reading the data of the read-only memory (ExpansionROM), and obtains the storage address of the hardware description information based on the data of the expansion read-only memory. The data of the ExpansionROM includes the driver of the expansion read-only memory ExpansionROM, and the driver obtains the storage address of the hardware description information. The ExpansionROM is an optional external EPROM (Erasable Programmable Read-Only Memory) chip of the PCI / PCIe device, which is used to store the initialization code or system startup code of the corresponding PCI / PCIe device. Therefore, at startup, the BIOS can obtain the initialization code or system startup code from the ExpansionROM, copy it to the RAM (Random Access Memory), and then execute the code, such as the driver code.

[0065] The system loads data from the expansion read-only memory (ROM) of the board and obtains the storage address of the hardware description information based on the data in the ROM. This includes: loading a driver from the memory and executing the driver; and reading the storage address of the hardware information table based on the driver. The BIOS obtains the driver from the expansion ROM and stores it in the server's RAM. The BIOS directs the ExpansionROM driver to run on the server. The ExpansionROM driver reads the address information of the system hardware information table (DSDT) and notifies the board of this address information.

[0066] Notifying the board of the storage address of the hardware description information includes: a driver determining the storage address of the hardware information table and writing the storage address of the hardware information table into a corresponding designated storage space of the board of the card. An ExpansionROM driver writes the storage address of the DSDT into a space register configured by the board of the card's VSEC (Vendor-Specific Extended Capability).

[0067] VSEC is an expansion capability provided to manufacturers as specified in the PCI specification and can be customized by the manufacturer. The present application embodiment, based on VSEC capabilities, configures the board at the factory, enabling the board to read the DSDT table based on VSEC. Consequently, when the server boots, the storage address of the DSDT is written to the VSEC space register, allowing the board to read the DSDT table.

[0068] Step 204 : The board obtains and parses the hardware description information based on the storage address of the hardware description information of the server to determine the extended configuration information of the server.

[0069] After the server completes the write operation of writing the storage address of the hardware description information into the designated storage space of the board, the board can be informed of the write operation, read the hardware description information based on the storage address accordingly, and then parse the hardware description information to determine the extended configuration information of the server.

[0070] The board obtains and parses the hardware description information based on the storage address of the hardware description information to determine the extended configuration information of the server, including: the board reads the storage address of the hardware information table from the configured storage space; the board's memory access controller, such as a DMA (Direct Memory Access) controller, obtains the hardware information table based on the storage address of the hardware information table; and parses the hardware information table to determine the extended configuration information of the server, wherein the extended configuration information includes: a bus extension range and a storage space extension range. After the ExpansionROM driver writes the storage address of the DSDT table to the board's space register, the board can be notified of the write operation. Thereafter, the DMA controller reads the storage address of the DSDT table from the space register, and then reads the DSDT table according to the storage address, parses the DSDT table, and determines the extended configuration information of the server, wherein the extended configuration information is the resource range of the external device that the server can expand. The bus expansion range refers to the range of buses that the server can support, that is, the number of buses it can support. A bus is a common path for information transmission between various functional components of a device. External devices can be connected to the board through the bus, and then to the server through the board. The storage space expansion range refers to the amount of storage space that can be expanded on the server.

[0071] Step 206: The board generates corresponding topology information based on the extended configuration information of the server.

[0072] In an embodiment of the present application, the external devices connected to the server are subject to the expansion capability limit of the server and are related to the expansion capability of the board. Generally, the board can support a larger bus range and storage space range, while the bus range and storage space range that the server can expand are relatively smaller. Therefore, when the board determines the number of connected external devices based on the extended configuration information, the resource configuration information of the board can also be obtained. The resource configuration information describes the bus range and storage space range that the board can support. Combined with the bus expansion range and storage space expansion range of the server, the number of external devices is determined, and the number of various types of external devices can be determined. The resource configuration information of the board can be obtained, and the resource configuration information includes the bus range and storage space range of the board; based on the bus range of the board and the bus expansion range of the server, the extended bus range is determined; based on the storage space range of the board and the storage space expansion range of the server, the extended bus range is determined; based on the extended bus range and the extended bus range, the number of connected external devices is determined.

[0073] For example, a board supports 50 buses and 100Mb of storage space, and the server supports 5 bus extensions and 100Mb of storage space. Each network card requires one bus and 1Mb of storage space, and each storage device requires one bus and 2Mb of storage space. Therefore, based on the board's resource configuration information and the server's extended configuration information, it can be determined that the board can connect to five external devices. Accordingly, the five external devices can be allocated, for example, to connect to three network cards and two storage devices, or to connect to two network cards and three storage devices.

[0074] After the number of external devices is determined, a topology structure of the external devices is allocated based on the number of external devices, and a bus for connecting each external device is allocated to obtain corresponding topology information.

[0075] The topology information is fed back to the server, so that the server can connect to the external devices connected to the board based on the topology information, thereby expanding the network resources and storage space of the server.

[0076] In summary, when the server starts up, it obtains the storage address of the hardware description information based on the data in the memory of the board, and notifies the board of the storage address of the hardware description information, so that the board can obtain the hardware description information and learn the server's expansion capabilities. The board obtains and parses the hardware description information based on the storage address of the hardware description information, determines the server's expansion configuration information, and generates corresponding topology information based on the expansion configuration information. This can accurately obtain the server's expansion capabilities and allocate the topology of external devices accordingly, allowing the server to connect to external devices. Since the server's hardware description information is obtained based on the data in the board's memory, there is no need to improve the server, and the system is applicable to various types of servers.

[0077] Based on the above embodiment, an embodiment of the present application further provides a resource expansion method for a server, so that the server can connect to an external device, wherein the server performs the following steps.

[0078] Reference Figure 3 , showing a step flow chart of an embodiment of a server resource expansion method of the present application.

[0079] Step 302: When the server starts, the server obtains the storage address of the hardware description information based on the data in the memory of the board.

[0080] Step 304: Notify the board of the storage address of the hardware description information, so that the board determines extended configuration information based on the hardware description information.

[0081] In summary, when the server starts, the BIOS obtains the storage address of the hardware description information and notifies the board of the storage address of the hardware description information, so that the board can obtain the hardware information of the server, thereby analyzing the expansion capabilities and setting the topology information of the external devices accordingly, ensuring that the server can connect to the external devices normally and expand the server's resources.

[0082] Reference Figure 4 , shows a step flow chart of another embodiment of a server resource expansion method of the present application.

[0083] Step 402: When the server is started, the BIOS generates hardware description information based on the system resources of the server. The hardware description information includes a DSDT table.

[0084] Step 404: BIOS loads the driver in the Expansion ROM of the board.

[0085] In step 406, the BIOS stores the driver program in RAM and executes the driver program.

[0086] Step 408: Determine the storage address of the DSDT table based on the driver, and write the storage address of the DSDT table into the storage space configured by the VSEC corresponding to the board.

[0087] In step 410 , the server receives topology information fed back by the board, and connects to external devices connected to the board based on the topology information.

[0088] The embodiments of the present application are applicable to servers of various models, and resources can be expanded in the above manner for both existing servers and newly added servers in the system.

[0089] Based on the above embodiments, the embodiments of the present application also provide a resource expansion method, which enables the board to obtain the expansion capabilities of the server and allocate the topology of external devices, so that the server can easily connect to external devices.

[0090] Reference Figure 5 , shows a step flow chart of an embodiment of a resource expansion method of the present application.

[0091] Step 502: After receiving the write operation for the storage address of the hardware description information of the server, the board reads and parses the corresponding hardware description information to determine the extended configuration information of the server.

[0092] The write operation is an operation in which the BIOS of the server writes the storage address of the hardware description information obtained based on the board into a designated storage space of the board, where the storage address is obtained based on data in a memory in the board.

[0093] Step 504: The board generates corresponding topology information based on the extended configuration information.

[0094] In summary, after the board receives the write operation for the storage address of the hardware description information, it reads and parses the corresponding hardware description information to determine the extended configuration information of the server, that is, the board can obtain the hardware information of the server, thereby analyzing the expansion capability, and setting the topology information of the external device based on the expansion capability of the server to ensure that the server is normally connected to the external device and expand the resources of the server.

[0095] Reference Figure 6 , shows a step flow chart of another resource expansion method embodiment of the present application.

[0096] Step 602: After receiving a write operation for the storage address of the DSDT table, the board reads the storage address of the DSDT table from the configured storage space.

[0097] Step 604: The DMA controller of the board accesses the storage address of the DSDT table and reads the DSDT table.

[0098] Step 606: Parse the DSDT table to determine the extended configuration information of the server.

[0099] The extended configuration information includes: a bus extension range and a storage space extension range.

[0100] Step 608: The board determines the number of connected external devices based on the extended configuration information.

[0101] Step 610: Allocate a topology structure of external devices based on the number of external devices to generate topology information.

[0102] Step 612: The board feeds back the topology information to the server.

[0103] This embodiment of the application pre-configures the VSEC of the card, allowing the server to notify the card of the address of the DSDT table. The card then obtains the server's hardware information, analyzes its expansion capabilities based on this information, and then sets the topology information of external devices based on the server's expansion capabilities, ensuring that the server can normally connect to external devices and expand the server's resources. This makes it applicable to servers of all models.

[0104] Based on the above embodiment, the embodiment of the present application also provides a resource expansion method, such as Figure 7 As shown:

[0105] Step 702: When the server starts, the BIOS generates hardware description information based on the system resources of the server.

[0106] Step 704: BIOS obtains the driver from the ExpansionROM of the board.

[0107] In step 706, the BIOS stores the driver program in RAM and executes the driver program.

[0108] Step 708: The driver determines the storage address of the DSDT table, and writes the storage address of the DSDT table into the storage space configured by the VSEC corresponding to the board.

[0109] Step 710: The board reads the storage address of the DSDT table from the configured storage space.

[0110] In step 712, the DMA controller of the board accesses the storage address of the DSDT table and reads the DSDT table.

[0111] In step 714, the board parses the DSDT table to determine the extended configuration information of the server.

[0112] The extended configuration information includes: a bus extension range and a storage space extension range.

[0113] Step 716: The board determines the number of connected external devices based on the extended configuration information.

[0114] Step 718: The board allocates a topology structure of the external devices based on the number of the external devices to generate topology information.

[0115] Step 720: The board feeds back the topology information to the server.

[0116] Step 722: The server connects to the external device connected to the board based on the topology information.

[0117] The embodiment of the present application is based on the standard specifications of PCIe and ACPI, so that the board can obtain the resource configuration of various servers and improve the compatibility of the board.

[0118] Taking the application in cloud computing scenarios as an example, the servers in the cloud computing system can be various types of cloud servers such as edge computing nodes and control servers. When the cloud server is started, it can connect to smart boards to expand resources in order to better provide services.

[0119] Reference Figure 8 , shows an interactive schematic diagram of an embodiment of a resource expansion method for a cloud server in a cloud computing system of the present application.

[0120] Step 802: When the cloud server starts, the BIOS generates hardware description information based on the server's system resources.

[0121] Step 804: BIOS obtains the driver from the ExpansionROM.

[0122] In step 806, the BIOS stores the driver program in RAM and executes the driver program.

[0123] Step 808: The driver determines the storage address of the DSDT table, and writes the storage address of the DSDT table into the storage space configured by the VSEC corresponding to the board.

[0124] Step 810: The board reads the storage address of the DSDT table from the configured storage space.

[0125] In step 812, the DMA controller of the board accesses the storage address of the DSDT table and reads the DSDT table.

[0126] In step 814, the board parses the DSDT table to determine the extended configuration information of the server.

[0127] The extended configuration information includes: a bus extension range and a storage space extension range.

[0128] Step 816: The board determines the number of connected external devices based on the extended configuration information.

[0129] Step 818: The board allocates a topology structure of the external devices based on the number of the external devices to generate topology information.

[0130] Step 820: The board feeds back the topology information to the server.

[0131] In step 822, the cloud server connects to the external device connected to the board based on the topology information.

[0132] The embodiment of the present application relies on standard specifications such as PCIE and ACPI to obtain server PCI resources so that the device can form a PCI topology that meets the server resource requirements, thereby improving device compatibility and fully utilizing server resources.
