Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
An embodiment of the present invention provides a method for replacing a hardware accelerator, where the method is applied to a back-end server, and please refer to fig. 1, which shows a flow diagram of the method for replacing the hardware accelerator, where the method may include:
step S101: a hardware accelerator replacement request is received.
The hardware accelerator replacement request is used for indicating that a first hardware accelerator used by a target virtual machine on a front-end server is replaced by a second hardware accelerator.
Illustratively, there are two virtual machines, namely virtual machine 1 and virtual machine 2, the hardware accelerators available for virtual machine 1 are hardware accelerator 1 and hardware accelerator 2, and the hardware accelerators available for virtual machine 2 are hardware accelerator 2, and assuming that virtual machine 1 is currently using hardware accelerator 2, in order to fully utilize the currently existing hardware accelerators without adding new hardware accelerators, the hardware accelerator used for virtual machine 1 can be replaced by hardware accelerator 2, and virtual machine 2 can use hardware accelerator 2.
Step S102: a notification message is sent to the front-end server to replace the first hardware accelerator.
Preferably, when receiving a notification message for replacing a hardware accelerator used by the target virtual machine, the front-end server determines whether the first hardware accelerator currently in use is idle, and if the first hardware accelerator is idle, sends a notification message indicating that the first hardware accelerator can be currently replaced to the back-end server. It can be understood that, if the current first hardware accelerator is executing a data processing task, the hardware accelerator is replaced immediately, which will inevitably interrupt the execution of the current data processing task, and further cause the data processing task to be unable to be executed and completed.
Step S103: and when a notification message indicating that the first hardware accelerator can be replaced currently is received, converting the pre-acquired virtual network service (VNF) configuration information corresponding to the target virtual machine into configuration information corresponding to the second hardware accelerator.
It should be noted that the virtual network service VNF configuration information is simple, abstract, and functionally described, so that the hardware accelerator cannot be configured directly by using the virtual network service VNF configuration information, and it needs to be converted into configuration information that conforms to configuration rules specific to the hardware accelerator vendor.
Step S104: the second hardware accelerator is configured based on configuration information corresponding to the second hardware accelerator.
Specifically, a configuration program provided by a vendor calling the second hardware accelerator configures the second hardware accelerator based on configuration information corresponding to the second hardware accelerator. At this point, the hardware accelerator replacement is complete, i.e., the hardware accelerator used by the target virtual machine is replaced with the second hardware accelerator.
In the method for replacing a hardware accelerator provided in the embodiments of the present invention, when a request for replacing a first hardware accelerator used by a target virtual machine with a second hardware accelerator is received, a notification message for replacing the first hardware accelerator may be sent to a front-end server, and when a notification message indicating that the hardware accelerator can be currently replaced is received, a piece of virtual network service VNF configuration information acquired in advance is converted into configuration information corresponding to the second hardware accelerator, and the second hardware accelerator is configured based on the configuration information corresponding to the second hardware accelerator, so that the first hardware accelerator used by the target virtual machine is replaced with the second hardware accelerator. As can be seen from the above process, the method for replacing a hardware accelerator according to the embodiment of the present invention can implement dynamic replacement of the hardware accelerator without sensing the underlying hardware accelerator, so that the hardware accelerator can be shared among multiple VNF virtual machines, that is, the utilization rate of the hardware accelerator is greatly increased, and accordingly, the hardware cost is greatly reduced.
Referring to fig. 2, a method for replacing a hardware accelerator according to an embodiment of the present invention is shown, where the method is applied to a back-end server, and referring to fig. 2, a flow chart of the method for replacing the hardware accelerator is shown, where the method may include:
step S201: a hardware accelerator replacement request is received.
The hardware accelerator replacement request is used for indicating that a first hardware accelerator used by a target virtual machine on a front-end server is replaced by a second hardware accelerator.
In one possible implementation, the hardware accelerator replacement request may come from carrier-class cloud platform management software.
Step S202: a notification message is sent to the front-end server to replace the first hardware accelerator.
Preferably, when receiving a notification message for replacing a hardware accelerator used by the target virtual machine, the front-end server determines whether the first hardware accelerator currently in use is idle, and if the first hardware accelerator is idle, sends a notification message indicating that the first hardware accelerator can be currently replaced to the back-end server. It can be understood that, if the current first hardware accelerator is executing a data processing task, the hardware accelerator is replaced immediately, which will inevitably interrupt the execution of the current data processing task, and further cause the data processing task to be unable to be executed and completed.
Step S203: and when a notification message indicating that the first hardware accelerator can be replaced currently is received, updating the hardware accelerator corresponding to the target virtual machine in the corresponding relation between the hardware accelerator and the virtual machine.
In some cases, since the hardware accelerators used by the virtual machines need to be known, the corresponding relationship between the virtual machines and the hardware accelerators needs to be maintained, in this embodiment, since the first hardware accelerator used by the target virtual machine needs to be changed to the second hardware accelerator, the first hardware accelerator corresponding to the target virtual machine in the maintained corresponding relationship between the virtual machines and the hardware accelerators needs to be changed to the second hardware accelerator, so as to ensure the accuracy of the maintained corresponding relationship between the virtual machines and the hardware accelerators.
Step S204: and converting the VNF configuration information which is acquired in advance and corresponds to the target virtual machine into configuration information corresponding to the second hardware accelerator.
The process of obtaining VNF configuration information corresponding to the target virtual machine in advance may include: when a creation request of a target virtual machine is received, creating a channel identifier; establishing a communication channel with the front-end server based on the channel identifier; and receiving VNF configuration information sent by the front-end server through a communication channel, wherein the VNF configuration information is sent by the front-end server to the back-end server when the target virtual machine is started. In a possible implementation manner, a backend server is deployed locally, and when a creation request of a target virtual machine is received, a file descriptor FD is created, a UNIX domain socket is created based on the file descriptor FD, and the file descriptor FD is sent to the frontend server. In another possible implementation manner, if the backend server is deployed remotely, a TCP connection channel between the front-end server and the backend server may be established, and the VNF configuration information is sent to the backend server through the TCP connection channel.
Optionally, when the front-end server sends the VNF configuration information to the back-end server, the front-end server may send information of the hardware accelerator at the same time, so that the back-end server allocates the hardware accelerator for the target virtual machine based on the information of the hardware accelerator, where the information of the hardware accelerator may be one or more of a type of the hardware accelerator, vendor information of the hardware accelerator, a characteristic of the hardware accelerator, and the like, and of course, when the front-end server sends the VNF configuration information to the back-end server, the back-end server may not send the information of the hardware accelerator, and allocate the hardware accelerator for the target virtual machine by itself.
It should be noted that, after obtaining the VNF configuration information, the back-end server converts the VNF configuration information into configuration information corresponding to the first hardware accelerator, where the configuration information corresponding to the first hardware accelerator is configuration information that conforms to a configuration rule specified by a manufacturer of the first hardware accelerator; the first hardware accelerator is configured based on the configuration information corresponding to the first hardware accelerator, that is, a configurator provided by a vendor calling the first hardware accelerator configures the first hardware accelerator based on the configuration information corresponding to the first hardware accelerator, so that the target virtual machine can use the first hardware accelerator. In addition, the backend server needs to establish a correspondence between the target virtual machine and the first hardware accelerator in the correspondence between the virtual machine and the hardware accelerator maintained by the backend server.
Step S205: the second hardware accelerator is configured based on configuration information corresponding to the second hardware accelerator.
Specifically, a configuration program provided by a vendor calling the second hardware accelerator configures the second hardware accelerator based on configuration information corresponding to the second hardware accelerator. At this point, the hardware accelerator replacement is complete, i.e., the hardware accelerator used by the target virtual machine is replaced with the second hardware accelerator.
Step S206: after the second hardware accelerator is configured, sending indication information of the second hardware accelerator configuration completion to the front-end server to indicate that the target virtual machine can use the second hardware accelerator.
In the method for replacing a hardware accelerator provided in the embodiments of the present invention, when a request for replacing a first hardware accelerator used by a target virtual machine with a second hardware accelerator is received, a notification message for replacing the first hardware accelerator may be sent to a front-end server, and when a notification message indicating that the hardware accelerator can be currently replaced is received, a hardware accelerator corresponding to the target virtual machine in a correspondence between the hardware accelerator and the virtual machine is updated, and VNF configuration information obtained in advance is converted into configuration information corresponding to the second hardware accelerator, and the second hardware accelerator is configured based on the configuration information corresponding to the second hardware accelerator, thereby replacing the first hardware accelerator used by the target virtual machine with the second hardware accelerator. As can be seen from the above process, the method for replacing a hardware accelerator according to the embodiment of the present invention can implement dynamic replacement of the hardware accelerator without sensing the underlying hardware accelerator and without stopping the VNF service, so that the hardware accelerator can be shared among a plurality of VNF virtual machines, that is, the utilization rate of the hardware accelerator is greatly increased, and accordingly, the hardware cost is greatly reduced.
The embodiment of the invention also provides a method for replacing the hardware accelerator, which is applied to the front-end server and can comprise the following steps:
step S301: indication information is received indicating a replacement of a first hardware accelerator used by a target virtual machine on a front-end server.
Step S302: when the first hardware accelerator is in an idle state, sending a notification message indicating that the first hardware accelerator can be replaced currently to the back-end server, so that the back-end server converts the pre-acquired VNF configuration information corresponding to the target virtual machine into configuration information corresponding to the second hardware accelerator, and configuring the second hardware accelerator based on the configuration information corresponding to the second hardware accelerator.
In addition, the method provided by the embodiment may further include: receiving indication information that the second hardware accelerator configuration is complete to indicate that the target virtual machine is able to use the second hardware accelerator.
When the front-end server receives the indication information that the configuration of the second hardware accelerator is completed, the target virtual machine can use the replaced second hardware accelerator to perform data processing, which indicates that the replacement of the hardware accelerator is completed.
The method for replacing the hardware accelerator provided by the embodiment of the invention can realize the dynamic replacement of the hardware accelerator, so that the hardware accelerator can be shared among a plurality of VNF virtual machines, namely the utilization rate of the hardware accelerator is greatly improved, and correspondingly, the hardware cost is greatly reduced.
