Detailed Description
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It should be understood that in the description of the application, "at least one" means one or more than one, and "a plurality" means two or more than two. In addition, the words "first," "second," and the like, unless otherwise indicated, are used solely for the purposes of description and are not to be construed as indicating or implying a relative importance or order.
Fig. 1 is a flow chart of a configuration method for a sideband interface protocol of a network controller according to an embodiment of the present application. As shown in fig. 1, the configuration method includes the following steps.
Step S110: and configuring at least two network interfaces according to a first binding mode through an operating system of the driving side so as to form a first binding port.
Step S120: and aggregating at least two Ethernet interfaces of a network interface card on a logic side corresponding to the at least two network interfaces based on the binding configuration of the first binding port so as to generate a first link aggregation group, wherein the binding configuration of the first binding port is determined based on the first binding mode, and the first link aggregation interface corresponds to the first link aggregation group.
Step S130: after generating the first link aggregation group, a network controller sideband interface module of the network interface card is notified about the first link aggregation group and the first link aggregation interface.
Step S140: and responding to the channel enabling command received from the board management controller through the network controller sideband interface module, analyzing the channel enabling command to determine a specific Ethernet interface indicated by the channel enabling command, judging whether collision exists based on the specific Ethernet interface, and if collision does not exist, updating an output interface of the board management controller to be the first link aggregation interface.
The command format of the channel enabling command is defined by a network controller sideband interface protocol and comprises a configuration type original equipment manufacturer command, wherein the configuration type original equipment manufacturer command at least comprises a network protocol address of the board level management controller, and the network controller sideband interface module is used for realizing interaction between the board level management controller and the network interface card by utilizing the network protocol address of the board level management controller and an output interface of the board level management controller.
Referring to fig. 1, a board level management controller (Baseboard Management Controller, BMC) generally refers to a small system integrated on a motherboard independent of a server system, has basic core functions, and provides out-of-band management of servers. The board-level management controller can communicate with the outside through an independent management Network port integrated on the server board, and in order to save the independent management Network port, the board-level management controller uses an Ethernet interface on a Network interface card (Network INTERFACE CARD, NIC) through a Network controller sideband interface (Network Controller-Sideband Interface, NC-SI) and communicates with the Network interface card according to a Network controller sideband interface protocol, so that the board-level management controller can use the Network interface card on a main board like the independent management Network port, thereby saving the independent management Network interface and reducing the cost of the server. When the operating system on the server deploys the service, a Binding (BOND) technology, also called Link Aggregation (LA) technology, may be adopted, which means that two or more ethernet interfaces are bound together, and the traffic is forwarded by using member interfaces under the same binding port in a manner such as hashing, polling, etc., so that a point-to-point communication technology can be used to increase bandwidth and improve reliability. Considering that the network controller sideband interface protocol allows the board level management controller to use the ethernet interface on the network interface card based on the channel strength, it is desirable to meet both the requirements of the network controller sideband interface protocol on the network interface card and the requirements of the binding technology, and to be able to flexibly adapt the requirements of the user for the input/output service customization, that is, to adapt the binding relation between various different network interfaces and the link aggregation relation between the ethernet interfaces, as will be described in further detail below.
With continued reference to fig. 1, at step S110, at least two network interfaces are configured according to a first binding mode by the operating system of the drive side to thereby construct a first binding port. Then, in step S120, at least two ethernet interfaces of the network interface card on the logical side corresponding to the at least two network interfaces are aggregated based on the binding configuration of the first binding port, thereby generating a first link aggregation group. The binding configuration of the first binding port is determined based on the first binding mode, and a first link aggregation interface corresponds to the first link aggregation group. Here, the operating system at the driving side forms the first binding port by two or more network interfaces, so that the bandwidth is increased, the reliability is improved, and the traffic forwarding can be performed on the member interfaces under the same binding port in a manner of hash, polling and the like. The first binding mode represents a binding relationship between the at least two network interfaces, e.g. a primary standby mode, i.e. one device is active and the other device is standby, and e.g. a broadcast mode, i.e. all packets are sent out from all network interfaces. The binding configuration of the first binding port represents a corresponding configuration of the first binding mode, so that the switch is configured accordingly based on the binding configuration of the first binding port, and at least two ethernet interfaces of the network interface card on the logic side, which correspond to the at least two network interfaces, are aggregated to generate a first link aggregation group. The first link aggregation group means that two or more ethernet links are bundled together to form one logical link, each link aggregation group (Link Aggregation Group, LAG) corresponding to one link aggregation interface, where the first link aggregation interface corresponds to the first link aggregation group. When forwarding traffic, the first link aggregation group needs to select one or more interfaces from the member interfaces for data forwarding. The link aggregation relation between the member interfaces of the first link aggregation group, i.e. the ethernet interfaces, is determined by the management plane of the operating system, and the at least two ethernet interfaces correspond to the at least two network interfaces. Therefore, depending on the actual configuration situation of the network interface card, for example, a plurality of physical network cards may be bound into one logical network card, and the corresponding relationship between the network interface on the driving side and the ethernet interface on the network interface card may be different, and considering that different tenants in the application scenario of multiple tenants may put various customization requirements on input and output, therefore, the binding relationship between various different network interfaces and the link aggregation relationship between the ethernet interfaces need to be adapted. As mentioned above, the network controller sideband interface protocol allows the board level management controller to use the ethernet interface on the network interface card based on the channel strength, so there may be a conflict between the usage requirements that the board level management controller puts on the ethernet interface on the network interface card based on the network controller sideband interface protocol and the usage requirements that the operating system puts on the ethernet interface based on the binding mode and link aggregation relationship, that is, there may be a conflict between the requirements from the management plane of the board level management controller and the requirements from the management plane of the operating system. Considering that the control plane of the board level management controller and the control plane of the operating system are independent of each other, in the case that the operating system adopts the binding technology, the requirement of the network controller sideband interface protocol on the network interface card and the requirement of the binding technology need to be satisfied at the same time, which will be described in detail below.
With continued reference to fig. 1, after the first link aggregation group is generated, a network controller sideband interface module of the network interface card is notified about the first link aggregation group and the first link aggregation interface at step S130. Here, the network controller sideband interface module is a dedicated module and dedicated hardware in the network interface card for implementing data interaction and traffic forwarding between the board level management controller and the network interface card. In step S140, by the network controller sideband interface module, in response to receiving a channel enable command from a board level management controller, the channel enable command is parsed to determine a specific ethernet interface indicated by the channel enable command, whether a collision exists is determined based on the specific ethernet interface, and if no collision exists, an output interface of the board level management controller is updated to be the first link aggregation interface. The command format of the channel enabling command is defined by a network controller sideband interface protocol and comprises a configuration type original equipment manufacturer command, wherein the configuration type original equipment manufacturer command at least comprises a network protocol address of the board level management controller, and the network controller sideband interface module is used for realizing interaction between the board level management controller and the network interface card by utilizing the network protocol address of the board level management controller and an output interface of the board level management controller. Here, based on the network controller sideband interface protocol, the channel between the board level management controller to the out interface of the board level management controller is established using configuration class original equipment manufacturer (Original Equipment Manufacturer, OEM) commands included in the command format of the channel enable command, in combination with the network controller sideband interface header of the channel enable command and other fields. it should be appreciated that for board level management controllers, the board level management controller simply issues channel-enabled commands having a command format defined by the network controller sideband interface protocol, and therefore, the management plane of the board level management controller is unaware of the management plane for the network interface card. In other words, the control plane of the board level management controller and the control plane of the operating system are independent from each other, the board level management controller does not sense the requirement from the control plane of the operating system, and the requirement of the network controller sideband interface protocol on the network interface card and the requirement of the binding technology are simultaneously met by utilizing the command format of the channel enabling command provided by the network controller sideband interface protocol and the configuration type original equipment manufacturer command in the command format. On the one hand, the operating system at the driving side configures at least two network interfaces according to a first binding mode so as to form a first binding port, and the corresponding Ethernet interfaces are aggregated based on the binding configuration of the first binding port, so that the requirements of the control surface of the operating system can be flexibly adapted; on the other hand, the conflict checking is carried out through the sideband interface module of the network controller, and when no conflict exists, the output interface of the board level management controller is updated to be the generated link aggregation interface, so that the requirements of the management and control surface of the board level management controller can be flexibly adapted; and finally, establishing a channel for interaction between the board-level management controller and the network interface card by utilizing the network protocol address of the board-level management controller included in the configuration-type original equipment manufacturer command. Therefore, the reliability and the bandwidth requirements of an operating system are met, and the management network port of a special board-level management controller is saved, so that the network interface card supports the use of the sideband interface technology and the binding technology of the network controller. In addition, the BMC uses the Ethernet interface on the NIC based on channel strength through the NC-SIC protocol, and the switch can forward through any Ethernet interface, and the configuration method for the sideband interface protocol of the network controller shown in figure 1 can simultaneously meet the requirements of the BMC and the two sides of the switch, so that the method is beneficial to meeting the service deployment requirements on the server.
Fig. 2 is a schematic diagram of a network interface card according to an embodiment of the present application. As shown in fig. 2, the operating system 212 on the drive side configures at least two network interfaces (network interface a220 and network interface B222 are exemplarily shown in fig. 2) to thereby construct a first binding port 224. On the network interface card 214, based on the binding configuration of the first binding port 224, at least two ethernet interfaces (ethernet interface a230 and ethernet interface B232) of the network interface card 214 on the aggregation logic side corresponding to the at least two network interfaces (network interface a220 and network interface B222) are generated to generate a first link aggregation group. The binding configuration of the first binding port is determined based on the first binding mode, and the first link aggregation interface 234 corresponds to the first link aggregation group. After the first link aggregation group is generated, the network controller sideband interface module 240 of the network interface card 214 is notified about the first link aggregation group and the first link aggregation interface 234. In response to receiving a channel enable command from the board level management controller 210, the network controller sideband interface module 240 parses the channel enable command to determine a specific ethernet interface indicated by the channel enable command, determines whether a conflict exists based on the specific ethernet interface, and updates an output interface of the board level management controller 210 to the first link aggregation interface 234 if no conflict exists. Wherein the command format of the channel enable command is defined by a network controller sideband interface protocol and includes a configuration class original equipment manufacturer command including at least a network protocol address of the board level management controller 210, the network controller sideband interface module 240 is configured to implement interaction between the board level management controller 210 and the network interface card 214 using the network protocol address of the board level management controller 210 and an outgoing interface of the board level management controller 210.
Referring to fig. 2, the network controller sideband interface protocol allows the board level management controller 210 to use the ethernet interface on the network interface card 214 based on channel strength, so there may be a conflict between the usage requirements that the board level management controller 210 puts on the ethernet interface on the network interface card 214 based on the network controller sideband interface protocol and the usage requirements that the operating system 212 puts on the ethernet interface based on binding mode and link aggregation relation, that is, there may be a conflict between the requirements from the management plane of the board level management controller 210 and the requirements from the management plane of the operating system 212. For example, the requirement of the management plane of the board management controller 210 is to use the ethernet interface a230, and the requirement of the management plane of the operating system 212 is to use the active-standby mode and use the ethernet interface a230 as the outgoing interface of the standby link, which means that only traffic passing through the active link, i.e., the ethernet interface B232, can be forwarded, thus facing a conflict between the requirement of the management plane from the board management controller 210 and the requirement of the management plane from the operating system 212.
The network interface card 214 shown in fig. 2, applying the configuration method for the network controller sideband interface protocol shown in fig. 1, establishes a channel for interaction between the board level management controller 210 and the network interface card 214. In this way, the reliability and bandwidth requirements of the operating system 212 are simultaneously satisfied, and the management network port of the special board-level management controller 210 is saved, so that the network interface card 214 supports the use of the network controller sideband interface technology and the binding technology at the same time.
Referring to fig. 1 and 2, in one possible implementation, when the network controller sideband interface module determines that there is a conflict, the network controller sideband interface module sends an asynchronous event notification to the board level management controller. In some embodiments, the asynchronous event notification is defined by the network controller sideband interface protocol and includes a connection status field to indicate whether a conflict exists between the particular ethernet interface and the first link aggregation group. Thus, with the network controller sideband interface protocol, a new type of notification, namely asynchronous event notification (Asynchronous Event Notification, AEN), can be defined, which can further extend the conflict resolution mechanism of the board level management controller and the operating system in terms of Ethernet interface usage.
In one possible implementation, the network controller sideband interface module determines that there is a collision when the particular ethernet interface indicated by the channel enable command belongs to the at least two ethernet interfaces and the channel enable command is received before the first bonded port is established. In this way, the channel enable command is received before the first bonding port is established, which means that the operating system has not completed configuring the bonding relationship when the board level management controller enables the ethernet interface having the bonding relationship, thus bringing about a use conflict. Thus, the conflict checking is realized by utilizing the expansibility of the channel enabling command.
In one possible implementation, the configuration class oem command further includes a connection mode field for indicating that the specific ethernet interface is shared between the board level management controller and the operating system, that the board level management controller monopolizes the specific ethernet interface, or that the board level management controller prefers to use the specific ethernet interface. Here, using the connection mode field, the usage of the board level management controller and the operating system with respect to the ethernet interface may be classified, thereby facilitating subsequent collision checking and port usage scheduling.
In some embodiments, the network controller sideband interface module determines that a conflict exists when the particular ethernet interface indicated by the channel enable command belongs to the at least two ethernet interfaces and the connection mode field indicates that the board level management controller monopolizes the particular ethernet interface. Here, the board level management controller monopolizes the specific ethernet interface, meaning that the board level management controller does not share the specific ethernet interface with the operating system. Thus, when the specific ethernet interface belongs to the at least two ethernet interfaces, this means that it is difficult for the operating system to use the specific ethernet interface in the first binding mode and the binding configuration of the first binding port, and thus there is a conflict.
In some embodiments, the network controller sideband interface module determines that a conflict exists when the particular ethernet interface indicated by the channel enable command does not belong to the at least two ethernet interfaces, the connection mode field indicates that the board level management controller monopolizes the particular ethernet interface, and the operating system requires use of the particular ethernet interface. Here, the specific ethernet interface does not belong to the at least two ethernet interfaces, which means that in the unbound mode, the board-level management controller monopolizes the specific ethernet interface and the operating system requires the use of the specific ethernet interface, so that it can be judged that there is a conflict.
In some embodiments, the network controller sideband interface module determines that there is no conflict when the particular ethernet interface indicated by the channel enable command belongs to the at least two ethernet interfaces and the connection mode field indicates that the board level management controller prefers the particular ethernet interface, and the scheduling priority of traffic associated with the board level management controller is higher than the scheduling priority of traffic associated with the operating system. In this way, since the exclusive mode is not configured and the board management controller is configured to preferentially use the specific ethernet interface, it can be determined that there is no conflict, and the network interface card is a high-priority schedule for the scheduling priority of the traffic associated with the board management controller, which helps to avoid packet loss of the board management controller when the operating system side flow is large.
In one possible implementation manner, the configuration method further includes: after updating the outbound interface of the board-level management controller to be the first link aggregation interface, the network interface card performs hash selection on the network traffic from the board-level management controller so as to select a member interface in the first link aggregation group corresponding to the first link aggregation interface to perform traffic forwarding. Thus, after being combined into the binding port and aggregated into the link aggregation group, the subsequent network traffic of the board level management controller is hashed by the network interface card within the link aggregation group to select the ethernet interface, which helps to increase bandwidth and improve reliability.
In some embodiments, the first binding mode is a primary and standby mode, and the configuration method further includes: executing, by the operating system, a handoff between the primary link and a backup link in response to a primary link failure, and informing the network controller of a handoff between the primary link and the backup link by a sideband interface module; and constructing a free address resolution protocol request corresponding to the network protocol address of the board level management controller through the network controller sideband interface module, and sending the address resolution protocol request through the standby link so as to update an address resolution protocol request interface corresponding to the network protocol address of the board level management controller. In this way, if the binding mode configured by the os is the active-standby mode, this means that when the switch fails, that is, when the primary link fails, a link switching may be performed and a free address resolution protocol (Address Resolution Protocol, ARP) request may be sent to the network interface corresponding to the standby link, so that the peer switch may refresh the outgoing interface corresponding to the network protocol address of the board level management controller, thereby completing the failover of the network on the os side. Therefore, the adaptation master-slave mode is realized, and the adaptation of the requirements of users on input and output business customization is facilitated, namely the adaptation of binding relations among various network interfaces and link aggregation relations among Ethernet interfaces is required.
In some embodiments, the first binding mode is a load balancing mode in a unstacking scenario, and the configuration method further comprises: and executing address resolution protocol request double-sending processing on the network protocol address of the board level management controller through the network controller sideband interface module. In this way, by performing address resolution protocol request double-sending processing, that is, ARP double-sending, on the network protocol address of the board management controller, a load balancing mode under the scenario of unstacking is achieved, which is beneficial to flexibly adapting the requirements of users for customizing input and output services, that is, the binding relationship between various different network interfaces and the link aggregation relationship between ethernet interfaces.
In one possible implementation, the configuration class original equipment manufacturer command further includes a vendor number field, a vendor custom subcommand field, and a binding mode enable field, where the vendor number field is used to indicate a vendor of the board level management controller, and the binding mode enable field is used to indicate whether the board level management controller uses binding. Thus, the network controller sideband interface protocol and the expansibility of the channel enabling command are utilized, so that the conflict checking and the port use scheduling are facilitated.
In one possible implementation, the first binding mode is a primary-standby mode, a load balancing mode, a broadcast mode, or a dynamic link aggregation mode. Thus, the control surface requirement of the operating system can be flexibly adapted.
