Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an adaptation control method for an OCP NIC network card according to an embodiment of the present invention. The method can comprise the following steps:
step 101: obtaining network card type information of an OCP NIC network card through an OCP adapter plate; and the OCP NIC network card is connected with the OCP adapter board.
It can be understood that the purpose of this step may be to obtain, by a processor in an adaptation control device (e.g., the intelligent control center in fig. 2) of the OCP NIC network card in the server, network card type information of the OCP NIC network card connected to the OCP adapter board through the OCP adapter board (e.g., the OCP Riser adapter board in fig. 2), so as to determine the network card type of the OCP NIC network card extrapolated from the server. That is, as shown in fig. 2, an OCP Riser adapter board (i.e., an OCP adapter board) may be connected to the OCP NIC network card and the intelligent control center (i.e., the adaptive control device), respectively.
Specifically, for the specific connection mode between the OCP adapter board and the adaptation control device and the OCP NIC network card in this embodiment, the specific connection mode may be set by a designer according to a practical scene and a user requirement, for example, when the server is an ARM (Advanced RISCMachine, a RISC instruction processing set with low power consumption cost) server, the adaptation control device (i.e., the intelligent control center CPLD) in the ARM server shown in fig. 3 may be connected to the OCP adapter board (i.e., the OCP RISER) through a golden finger, and the OCP adapter board may be connected to the OCP NIC network card through a Primary 4C +/Secondary4C connector (i.e., a Primary 4C + Conn and a Secondary4C Conn). As long as the processor of the adaptive control device in the server can obtain the network card type information of the OCP NIC network card through the OCP adapter board, this embodiment does not impose any limitation on this.
It should be noted that, in this step, a specific manner in which the processor of the adaptation control device obtains the network card type information of the OCP NIC network card through the OCP adapter board may be set by a designer, as shown in fig. 3 and 4, the OCP adapter board (i.e., OCP RISER) may receive the network card type information (i.e., the state of PRSNTB [3:0 ]) of the OCP NIC network card (e.g., the network card of the OCP NIC 3.0) through the Primary 4C +/Secondary4C connector (i.e., Primary 4C + Conn and Secondary4C Conn), and then the OCP adapter board transmits the network card type information to the adaptation control device (i.e., the intelligent control center CPLD) through a gold finger. The present embodiment does not set any limit to this.
Specifically, the embodiment does not limit the specific content of the network card type information of the OCP NIC network card, and may be set by a designer, for example, when the OCP NIC network card is an OCP NIC 3.0 network card, the network card type information of the OCP NIC network card may be the state of the PRSNTB [3:0] signal.
Step 102: acquiring connection information of a CPU corresponding to an OCP NIC network card through an OCP adapter board; the CPU is connected with the OCP NIC network card through the OCP adapter board, and the connection information comprises CPU address information.
It can be understood that, in this step, the CPU corresponding to the OCP NIC network card may be a CPU capable of performing subsequent PCIe communication with the OCP NIC network card, such as all or part of CPUs that establish PCIe connection with the OCP patch board. The purpose of this step may be that a processor in an adaptation control device (for example, the intelligent control center CPLD in fig. 3) of the OCP NIC network card in the server acquires, through an OCP RISER (for example, the OCP RISER in fig. 3), connection information of a CPU that is connected to the OCP RISER and that is capable of performing subsequent PCIe communication with the OCP NIC network card, so as to determine a specific connection condition of CPUs that are capable of performing subsequent PCIe communication with the extrapolated OCP NIC network card in the server, that is, a PCIe link condition where each CPU is connected to the OCP RISER. That is, as shown in fig. 3, the OCP patch panel (i.e., OCP RISER) may be connected to the CPU (i.e., PU0 and CPU1) corresponding to the OCP NIC network card through a SlimSAS (an interface specification) connector.
Specifically, for the specific connection mode of the OCP patch panel and the CPU corresponding to the OCP NIC network card in this embodiment, a designer may set the connection mode by himself according to a practical scenario and a user requirement, for example, when the server is an ARM server, as shown in fig. 3 and 5, the OCP patch panel (i.e., OCP RISER) is connected to the CPU (i.e., CPU0 and CPU1) corresponding to the OCP NIC network card through a SlimSAS connector, for example, 4 SlimSAS connectors may be set on the OCP patch panel, each SlimSAS connector is connected to the SlimSAS connector of one CPU through an x8 SlimSAS line, that is, the CPU0 and the CPU1 are respectively connected to 2 SlimSAS connectors on the OCP patch panel. As long as the processor of the adaptive control device in the server can obtain the connection information of the CPU corresponding to the OCP NIC network card through the OCP adapter board, this embodiment does not limit this.
It should be noted that, in this step, a specific manner in which the processor of the adaptation control device obtains the connection information of the CPU corresponding to the OCP NIC network card through the OCP patch panel may be set by a designer, as shown in fig. 3 and fig. 5, the processor of the adaptation control device may read a logic state of an IO port (input/output port) of a preset chip (e.g., PCA9555 chip) in the OCP patch panel through an I2C (Inter-Integrated Circuit bus) signal connected to the OCP patch panel, and obtain a CPU Address ID (i.e., CPU Address information in the connection information) of an upstream PCIe signal of the OCP NIC network card, so as to determine which CPU (CPU0 or CPU1) the 1st/2 x8 lane SlimSAS comes from; the preset chip may be a chip which is arranged in the OCP adapter board and stores connection information of the CPU. The present embodiment does not set any limit to this.
Specifically, the specific content of the connection information of the CPU corresponding to the OCP NIC network card may be set by a designer, and as shown in fig. 5, the connection information of the CPU may include a CPU Address ID (CPU Address information). As long as the processor of the adaptation control device can determine, according to the connection information of the CPU, the PCIe link of the specific connection between the CPU corresponding to the OCP NIC network card and the OCP patch board (i.e., the OCPNIC network card) and the CPU connected to each PCIe link, which is not limited in this embodiment.
It can be understood that there is no necessary logical order between this step and step 101, and this step may be performed first in step 101 and then in this embodiment, or this step may be performed first and then in step 101, or two steps may be performed simultaneously, which is not limited in this embodiment.
Step 103: and determining the working mode of the OCP NIC according to the network card type information and the connection information.
It can be understood that the purpose of this step may be that the processor of the adaptation control device determines, according to the network card type information of the OCP NIC network card and the connection information of the CPU corresponding to the OCP NIC network card, a working mode in which the processor of the OCP NIC network card performs PCIe communication with a corresponding CPU (i.e., a target CPU), so as to determine a target CPU and an upstream PCIe link and a bandwidth in which the OCP NIC network card performs PCIe communication. That is, the working mode of the OCP NIC network card determined in this step may include: target CPU information, upstream PCIe link information, and bandwidth information.
Specifically, the specific manner in which the processor of the adaptation control device determines the working mode of the OCP NIC network card in this step according to the network card type information and the connection information may be set by a designer, and the processor may search the working mode of the OCP NIC network card corresponding to the network card type information and the connection information by using a preset working mode selection list according to the network card type information and the connection information, that is, the optimal working mode of different types of OCP NIC network cards under various CPU connection conditions may be set in the preset working mode selection list. For example, when the OCP NIC network Card is an OCP NIC 3.0 network Card, the preset working mode selection list may be "Table 36: PCIe Bifurcation Decoder for x32, x16, x8, x4, x2 and x1 Card width" in the OCP NIC 3.0 protocol, that is, the processor may perform a list query according to the network Card type information and the connection information and according to "Table 36: PCIe Bifurcation Decoder for x32, x16, x8, x4, x2 and x1 Card width" in the OCP NIC 3.0 protocol, so as to obtain the working mode of the OCP NIC network Card.
Step 104: controlling an OCP NIC network card and a target CPU, and carrying out PCIe communication according to an upstream PCIe link and a bandwidth corresponding to a working mode; the target CPU is a CPU corresponding to the working mode in the CPU.
It can be understood that the purpose of this step may be that the processor of the adaptation control device controls the OCP NIC network card and the CPU (i.e., the target CPU) corresponding to the determined working mode, so that the subsequent OCP NIC network card and the target CPU may perform PCIe communication according to the upstream PCIe link and the bandwidth corresponding to the working mode, thereby implementing dynamic adjustment of the upstream PCIe link and the bandwidth of the OCP NIC network card, enabling the server to compatibly adapt to multiple types of OCP NIC network cards, reducing machine room operation and maintenance accidents caused by incompatibility of the inserted OCP NIC network cards, and improving user experience.
Specifically, the processor of the adaptive control device in this step controls the OCP NIC network card and the target CPU, and the specific mode of PCIe communication according to the upstream PCIe link and the bandwidth corresponding to the working mode may be set by the designer, for example, when the server is an ARM server, that is, a server of an ARM architecture, since the ARM server needs to complete the splitting of the upstream PCIe link and the bandwidth before the start-up, the processor in this step may complete the splitting of the upstream PCIe link and the bandwidth between the OCP NIC network card and the target CPU before the target CPU starts up; for example, the step may include sending the working mode to the BIOS through the OCP patch panel, so as to complete the configuration of the upstream PCIe link and the bandwidth corresponding to the working mode before the target CPU is powered on by using the BIOS; as shown in fig. 6, after determining the working mode of the OCP NIC network card, the processor of the adaptation control device (i.e., the intelligent control center) may set a BID (i.e., BW _ TYPE _ ID) state corresponding to the working mode through a general GPIO Expansion (i.e., input/output interface) in the OCP patch board (i.e., OCP RISER), so that the OCP patch board reports the BID state to a preset working mode chip (e.g., PCA9555 chip) on the motherboard through a cable, so that the BIOS (basic input/output system) on the motherboard can read the BID state through I2C to determine the working mode of the OCP NIC network card, and complete splitting of an upstream PCIe link and a bandwidth between the OCP NIC network card corresponding to the working mode and the target CPU.
Correspondingly, the step may further include the step of transmitting the determined working mode of the OCP NIC network card to the OCP NIC network card and the target CPU by the processor of the adaptation control device, so that the subsequent OCP NIC network card and the target CPU may perform PCIe communication according to the upstream PCIe link and the bandwidth corresponding to the working mode. As shown in fig. 6, after the BIOS on the motherboard reads the BID state through I2C to determine the working mode of the OCP NIC network card, and completes the splitting of the upstream PCIe link and the bandwidth between the OCP NIC network card corresponding to the working mode and the target CPU, the read BID state may be transmitted to the target CPU (e.g., CPU0) through I2C; as shown in fig. 7, after determining the working mode of the OCP NIC network card, the processor of the adaptive control device (i.e., the intelligent control center) may set a BIF [2:0] signal corresponding to the working mode through a general GPIO Expansion (input/output interface) in the OCP RISER (i.e., the OCP RISER), so that the OCP NIC network card can obtain the BIF [2:0] signal through the Primary 4C +/Secondary4C connector (i.e., the Primary 4C + Conn and the Secondary4C Conn), and obtain the determined working mode of the OCP NIC network card.
In this embodiment, the working mode of the OCP NIC network card is determined according to the type information and the connection information of the network card, and the working mode of the OCP NIC network card is determined by using the type of the OCP NIC network card and the connection information of the CPU, which are obtained in real time; through controlling the OCP NIC network card and the target CPU, PCIe communication is carried out according to an upstream PCIe link and a bandwidth corresponding to a working mode, and the upstream PCIe link and the bandwidth are dynamically split by utilizing the determined working mode of the OCP NIC network card, so that the server can be compatible with various OCP NIC network cards, machine room operation and maintenance accidents caused by inserting the OCP NIC network cards in error are reduced, and user experience is improved.
