Description

vNIC main and standby port selection method, device and medium thereof
Technical Field
The present invention relates to the field of network communications technologies, and in particular, to a method, an apparatus, and a medium for selecting a vNIC active/standby port.
Background
Power: performance Optimization With Enhanced RISC, one of the most common CPU architectures. PowerVM: the general term for virtualization technology on a Power server. PowerVC: power Virtualiztion Center, is an official unique private cloud management platform based on a Power mini-machine server and is based on open-source OpenStack implementation. OpenStack: the cloud computing management platform project is an open source cloud computing management platform project, and is a combination of a series of software open source projects. OpenStack provides scalable and resilient cloud computing services for private and public clouds. The project aims to provide a cloud computing management platform which is simple to implement, can be expanded in a large scale, is rich and has unified standards. Currently, the PowerVM provides two ways to implement network virtualization, and when a virtual machine is deployed through an SR-IOV network virtualization way, the PowerVC selects an SR-IOV physical port to be used by the virtual machine through a port label way in network definition.

PowerVC adopts vNIC technology when deploying virtual machines through SR-IOV network virtualization.

Meanwhile, in the current practical production environment, in order to reduce the influence of network problems on devices, there are generally two groups of physical ethernet networks, which are connected to each other and are redundant to each other, and different groups of physical ethernet networks correspond to different network switches. Therefore, when the virtual machine is deployed by using the SR-IOV redundancy mode, and the two selected SR-IOV physical ports on the same physical machine are connected to different network switches, the vNIC device of the virtual machine has redundancy of a switch layer.
In the current PowerVC design and implementation, the PowerVC cloud pipe platform cannot define or identify the topology structure of the traditional network, and the situation that two selected SR-IOV physical ports are connected to the same network switch occurs, at this time, the vNIC device of the virtual machine loses redundancy of the switch layer, and if the single-point switch fails, the vNIC of the virtual machine loses all network connections, so that the problem of service termination is caused.
Therefore, a need exists for a vNIC active/standby port selection method that solves the problem of connecting two selected SR-IOV physical ports to the same network switch in the current PowerVC design and implementation.

Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a vNIC master and slave port selection method, a vNIC master and slave port selection device and a medium thereof.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
When deploying a virtual machine through an SR-IOV network virtualization manner, two mappings for vNIC active and standby ports may be randomly selected from SR-IOV physical ports defined by a network in the existing PowerVC design and implementation. In an actual production environment, in order to reduce the problem that the virtual machine is affected due to network reasons, two groups of physical ethernet networks are deployed, and the two groups of networks are mutually communicated and redundant, so as to ensure that when one group of networks fails, the virtual machine can continuously provide services to the outside through the other group of networks. However, since the vNIC device of the virtual machine is connected to the network group through the switch, when two ports for mapping the vNIC primary and secondary ports randomly selected by the existing PowerVC are located in the same network group, the two ports are connected to the network group through the same switch, which makes the vNIC device of the virtual machine lose redundancy of the switch layer. If this single point switch fails, then the vNIC of the virtual machine will lose all network connections, causing a traffic outage. Therefore, as shown in fig. 1, the present application provides a vNIC active/standby port selection method, including:
s110: adding a new network tag definition for each SR-IOV physical port of the physical host;
s120: receiving a network group tag value of an SR-IOV physical port;
s130: when the virtual machine is created, a main port is selected from SR-IOV physical ports located in network definition on a target host, a network group where the main port is located is recorded, and a standby port is selected from SR-IOV physical ports different from the network group where the main port is located.
It should be noted that, the specific form of the network group tag value is not limited in this application, and may be freely selected according to the actual situation and needs, but this example provides a possible implementation: the legal values of the network group labels are NG1 and NG2, which respectively indicate that the port is connected with the first network group and the port is connected with the second network group, meanwhile, when a larger number of network groups exist in actual use, the legal values of the network labels can also be NG3 and NG4, and the embodiment does not limit the number of the network groups to be only two.
Meanwhile, the present embodiment does not limit the selection of several ports as the primary port or the backup port, but the general implementation is as follows: the main port and the standby port are one. In addition, when the number of the alternative ports meeting the conditions described in the present embodiment is plural, the present embodiment does not limit the selection logic for specifically selecting the primary port or the backup port, and it is easy to understand that no matter what the selection logic is, the technical effect that the primary port and the backup port are not located in the same switch can be achieved as long as the ports that can be selected when the backup port is selected are located in different network groups from the primary port.
Because the structure of the traditional network cannot be identified in the design and implementation of the existing PowerVC, the description information of network topology is added for the SR-IOV physical ports defined by the network, and an operator sets the description information, namely the network group label value, to indicate the network group to which the corresponding SR-IOV physical ports are specifically connected, so that when a virtual machine is created, after one main port is randomly selected, the main port can be known to be connected with the network group through the network label value, and then the port on the other network group is selected when the spare port is selected, thereby enabling the main port and the spare port not to be connected with the same network group, namely not to be connected with the same switch, and when one switch fails, the vNIC device of the virtual machine cannot lose all network connections to cause service interruption.
As can be seen from the foregoing, the present application realizes redundancy of the vNIC device of the virtual machine on the switch layer, and does not cause loss of all network connections when a single switch fails, but in actual production use of the SR-IOV physical port to be used in the vNIC device of the virtual machine, in terms of the server, a plurality of physical entities are used together as one logical body when implementing a certain function, and each physical entity constituting the logical body may be referred to as a drawer. Therefore, if the SR-IOV physical ports corresponding to the main port and the standby port are located in the same drawer, when the drawer fails, the main port and the standby port cannot work normally, and in order to solve this problem, the embodiment provides a preferred implementation manner based on the above embodiment, and selecting the standby port includes:
s131: and selecting a port which is not positioned in the same drawer as the main port as a standby port.
It is easy to understand that when there is no port satisfying both conditions, a port satisfying the condition that the port is not located in the same network group as the master port may be selected at will, or the port may not be selected and reported or otherwise, which is not limited in this embodiment, and a suitable selection logic may be selected according to the actual situation.
The advantage of this embodiment over the above-described embodiments is that: according to the embodiment, when the standby port is selected on the basis of the embodiment, the selection logic is further subdivided, so that the selected standby port is selected if the port which is not located in the same drawer as the main port is located in the condition that the selected standby port is not located in the same network group with the main port, the problem that the main port and the standby port cannot work normally when the drawer fails is avoided, redundancy of the main port and the standby port is further guaranteed on the drawer level, and reliability is improved.
As described in the foregoing embodiment, on the basis of guaranteeing redundancy of the primary port and the backup port on the switch layer, redundancy of the primary port and the backup port on the drawer layer is further guaranteed, and meanwhile, because the SR-IOV physical port is also connected with different adapters, the embodiment further provides a preferred scheme on the basis of the foregoing embodiment, where selecting the backup port further includes:
s132: when there is no port which is not located in the same drawer as the main port, a port which is not located in the same adapter as the main port is selected as the standby port.
Based on the above embodiment, when the standby port is selected, the embodiment determines whether the standby port is located in the same network group or the same drawer as the main port, and also determines whether the standby port is located in the same adapter, and selects a port which is not located in the same adapter as the main port as the standby port, so that redundancy of the main port and the standby port on the adapter layer is realized, one of the adapters connected with the main port or the standby port is ensured not to be affected when the other adapter fails, and reliability is further enhanced.
In the method for selecting the primary and standby ports of the vNIC provided by the present application, only the ports which are not in the same network group as the primary port are selected when the standby port is selected, but the situation that the ports which do not meet the condition are not selected when the standby port is selected is unavoidable, so the present embodiment provides a preferred embodiment for the problem:
s133: selecting the backup port also includes returning an error message when there is no SR-IOV physical port other than the network group in which the primary port is located.
It should be noted that, in this embodiment, the specific embodiment of the return error information and the specific content of the error information are not limited, and may be freely selected according to practical situations. In addition, this embodiment is directed to the case when there is no SR-IOV physical port different from the network group where the master port is located, and if the conditions mentioned in the above embodiments are not satisfied, for example, if the SR-IOV physical port is not located in the same drawer or the same adapter as the master port, the embodiment does not limit whether to return the error information, and may return the error information, or may randomly select one as the backup port under the condition that the SR-IOV physical port is satisfied that the master port is not located in the same network group.
In the embodiment, when the SR-IOV physical port which is different from the network group where the main port is located is not available for selection as the standby port, the error information is returned to prompt an operator to process in time, so that the working reliability of the vNIC equipment of the virtual machine is further ensured.
Since one SR-IOV physical port may be used as a primary port or a backup port of multiple vNIC devices, and it is easy to understand that the more tasks that one SR-IOV physical port assumes for a primary port or a backup port of a vNIC device, the greater the network traffic it carries, and when exceeding the limit value, the effect on the normal operation of the vNIC device will be exerted, so this embodiment provides a preferred scheme, before selecting the primary port, further including:
s201: according to the service condition of the SR-IOV physical port, carrying out corresponding addition and subtraction operation on the main port count value and the standby port count value of the SR-IOV physical port, wherein when a virtual machine is created, the SR-IOV physical port is selected to support the vNIC main port, the main port count value is increased by 1, the SR-IOV physical port is selected to support the vNIC standby port, the standby port count value is increased by 1, when the virtual machine is migrated or deleted, the SR-IOV physical port is selected to support the vNIC main port, the main port count value is decreased by 1, the SR-IOV physical port is selected to support the vNIC standby port, and the standby port count value is decreased by 1;
correspondingly, selecting the master port includes:
s202: the SR-IOV physical ports meeting the conditions are arranged in ascending order according to the count value of the main port, and the first SR-IOV physical port is selected as the main port;
selecting the backup port comprises:
s203: and arranging the SR-IOV physical ports meeting the conditions in ascending order according to the spare port count value, and selecting the first SR-IOV physical port as the spare port.
It should be noted that, when the primary port count value or the backup port count value is arranged in ascending order, a situation may occur that some SR-IOV physical port count values are the same, and since the SR-IOV physical ports with the same count value will not affect the effect brought by the implementation provided in this embodiment no matter how the SR-IOV physical ports are arranged, the SR-IOV physical ports can be freely arranged according to actual needs, and this embodiment does not limit the implementation, but provides a possible implementation as follows:
s204: when the SR-IOV physical ports are arranged according to the main port count value or the standby port count value, if the count values are the same, the SR-IOV physical ports with the same count values are arranged according to the alphabetic order of the port slot numbers.
It is to be understood that this embodiment only requires that the SR-IOV physical ports with the same count value be arranged in the alphabetical order of the port slot numbers, and is not limited as to the arrangement of the ports in the alphabetical order, the descending order, or other order of the alphabetical order of the port slot numbers.
Because the primary port and the standby port are required to be allocated to the vNIC device when the virtual machine is created, the corresponding count value of the selected SR-IOV physical port needs to be increased every time the virtual machine is created, and deleting or migrating the virtual machine indicates that the current virtual machine is to stop working temporarily, and the corresponding primary port and the corresponding standby port are not used any more, so that the use condition of each SR-IOV physical port needs to be obtained by subtracting the corresponding count value of the selected SR-IOV physical port, and when the ports are allocated, the use condition of each SR-IOV physical port can be known.
When the two SR-IOV physical port count values are the same, the two SR-IOV physical port count values are arranged according to the alphabetical order of the port slot numbers, so that the whole ordering process is more accurate, the alphabetical order of the port slot numbers is the existing attribute of the ports, the alphabetical order of the port slot numbers is used as the ordering basis, new information is not required to be added additionally, and the storage space is saved.
As can be seen from the above embodiments, the method for selecting a vNIC primary and secondary port provided in the present application needs to be implemented on a cloud management layer, so in order to better illustrate the method for selecting a vNIC primary and secondary port provided in the present application, the embodiment provides a preferred implementation of the method for selecting a vNIC primary and secondary port implemented on a cloud management layer, as shown in fig. 2, including: host management module 21, network management module 22, resource scheduling module 23, and World Wide Web (Web) interface 24;
the host management module 21 adds a new tag definition to each SR-IOV physical port of the physical host, i.e. step S110, and stores the identification information in the host table of the cloud management platform database 25, and the WEB group tag value of each SR-IOV physical port is set by the WEB interface 24.
The WEB interface 24 provides an interface for an operator to set the network group tag value. The operator may select a tag value of the network group to which each SR-IOV physical port belongs at the SR-IOV port column of the host management menu of WEB interface 24, such as one of the implementations mentioned in the examples above: the legal values of the network group labels are NG1 and NG2, which respectively indicate that the port is located in the first network group and the port is located in the second network group. After the save network group tag is set, the network group tag value for each SR-IOV physical port is sent to the host management module 21 for its saving in the database.
The network management module 22 records that each SR-IOV physical port on the host is used to count the primary port count value and the backup port count value, that is, step S201 is implemented.
The resource scheduling module 23 is responsible for selecting appropriate primary and backup ports for the vNIC device when creating the virtual machine, and the selection logic for selecting the primary and backup ports is:
s301: the SR-IOV physical ports on the target host computer in the network definition are arranged according to the ascending order of the count value of the main port, if the count values are the same, the SR-IOV physical ports are arranged according to the alphabetical order of the port slot numbers;
s302: selecting a first port arranged in ascending order in the step S301 as a main port, and recording a network group in which the port is located;
s303: the SR-IOV ports which are positioned in the network definition and belong to another network group on the target host are arranged according to the ascending order of the count values of the standby ports, and if the count values are the same, the SR-IOV ports are arranged according to the alphabetical order of the port slot numbers;
s304: selecting the port which is arranged in ascending order and is not positioned in the same drawer with the main port in the step S303 as a standby port, and entering the step S305 if the port meeting the condition does not exist;
s305: selecting the port of the first adapter which is not located in the same adapter with the main port in ascending order in the step S303 as a standby port, and if no port meeting the condition exists, entering the step S306;
s306: selecting the first port in ascending order in the step S303 as a standby port, and if the first port does not exist, entering the step S307;
s307: an error message is returned.
