Description

Technical Field

[0001] The present invention relates to the field of cloud computing technology, and in particular to a bare metal server online system, method, and device. Background Art

[0002] In the related art, users can create bare metal servers through cloud platform management devices and operate bare metal servers to go online. Generally speaking, bare metal servers ultimately need to be put online in the business network specified by the user.

[0003] However, before the preceding process, that is, when creating a bare metal server, the host system has not yet been deployed on it. Therefore, you must first connect the bare metal server to the pre-provisioned network and retrieve the user-specified system image file from the provision network to run the host system using the system image file. After the host system is deployed, the bare metal server is switched from the provision network to the business network. This phase of switching the bare metal server from the provision network to the business network is called the provisioning phase, and the entire provisioning phase takes a considerable amount of time.

[0004] If cloud hosts continue to come online in the business network during the provisioning phase, the online cloud hosts will occupy the available Internet Protocol (IP) addresses of the business network. As a result, after the bare metal server is switched from the provisioning network to the business network, there will be no available IP addresses in the business network for the bare metal server to go online in the business network, which will ultimately cause the bare metal server to fail to go online in the business network. Summary of the Invention

[0054] By adopting the present invention, regardless of whether there are any available IP addresses in the business network, a separate IP address is not used to create the first DHCP port and run the first DHCP service. Instead, the first DHCP port is created and the first DHCP service is run by reusing the gateway address of the gateway device of the business network. Since the gateway address of the gateway device of the business network generally exists, creating the first DHCP port and running the first DHCP service by reusing the gateway address can ensure that the first DHCP port can be successfully created and the first DHCP service can be successfully run. When the first DHCP port and the first DHCP service can be successfully created or run, the DHCP server can normally respond to the first DHCP request received from the bare metal server, thereby ensuring that the IP address of the business network can be normally allocated to the bare metal server. In this way, the bare metal server can successfully go online on the business network without failure due to the lack of available IP addresses in the business network.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "an," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, and unless the context clearly indicates otherwise, "a plurality" generally includes at least two.

[0065] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0066] In addition, the step sequence in the following method embodiments is only an example and not a strict limitation.

[0067] Figure 1 A schematic diagram of the structure of a bare metal server online system provided by an embodiment of the present invention is shown as follows: Figure 1 As shown, the system may include a cloud platform management device 11 , a Dynamic Host Configuration Protocol (DHCP) server 12 and a bare metal server 13 .

[0068] Among them, the cloud platform management device 11 can be a device built with Openstack (a cloud computing management platform). Through Openstack in the cloud platform management device 11, resource management can be achieved, and resources can be provided to upper-layer applications or users in the form of services. Openstack can be composed of multiple components, and different components are used to implement different functions and provide different services. The components included in Openstack can be, for example, Neutron, Ironic and other components. Among them, Neutron can be used to provide network services, and Ironic can be used to manage bare metal servers 13 and provide services such as deployment and power management.

[0069] A variety of functions can be implemented based on Openstack, including creating virtual machines, managing virtual machine launches, creating bare metal servers 13, and managing bare metal server 13 launches.

[0070] A virtual machine is an operating system that simulates complete hardware system functions through software and runs in a completely isolated environment. Any work that can be done on a physical server can also be done on a virtual machine. When creating a virtual machine on a server, part of the server's hard drive and memory capacity is used as the virtual machine's hard drive and memory capacity. Each virtual machine has its own independent complementary metal oxide semiconductor (CMOS), hard drive, and operating system, allowing it to be operated just like a physical server.

[0071] However, virtual machines execute tasks by invoking underlying physical resources through the virtualization platform or virtual machine controller. Consequently, virtual machines suffer from performance penalties, and especially for tasks requiring high performance (such as high-performance computing), performance limitations can lead to significant latency during the execution of these tasks.

[0072] This is why bare metal servers (BMSs) have emerged. These servers are physical servers with real physical resources. They are flexible and elastic, offering high-performance computing capabilities comparable to traditional physical servers while also offering secure physical isolation.

[0073] It is understood that if a bare metal server 13 is to be used to perform user-specified tasks, it is necessary to create the bare metal server 13 before actually using it, and then connect the bare metal server 13 to the service network established by the user. Connecting the bare metal server 13 to the service network may include configuring an IP address for the service network for the bare metal server 13. The DHCP server 12 in the system provided in this embodiment of the present invention is used to assign an IP address for the service network to the bare metal server 13 when the bare metal server 13 comes online.

[0074] In addition, the DHCP server 12 in the embodiment of the present invention may be a centralized DHCP server 12. Unlike a distributed DHCP server 12, the centralized DHCP server 12 is a server dedicated to allocating IP addresses to the bare metal servers 13. Specifically, the centralized DHCP server 12 provides an IP address allocation service to the bare metal servers 13 through a centralized DHCP service.

[0075] The functions of each device in the system provided by the embodiment of the present invention may include:

[0076] The cloud platform management device 11 is configured to perform network configuration for the physical switch connected to the bare metal server 13 upon detecting that the bare metal server 13 has switched from the provisioning network to the service network. The device obtains the gateway address of the gateway device corresponding to the service network and creates the first DHCP port for the service network by reusing the gateway address.

[0077] The DHCP server 12 is configured to create a first DHCP service in response to the creation operation of the first DHCP port, and run the first DHCP service through the gateway address.

[0078] The bare metal server 13 is configured to send a first DHCP request corresponding to the service network to the DHCP server 12 through a physical switch configured corresponding to the service network.

[0079] The DHCP server 12 is configured to respond to the first DHCP request through a first DHCP service to allocate an IP address in the service network to the bare metal server 13 .

[0080] like Figure 2 FIG. 1 is a diagram showing signaling interactions between devices in a system according to an embodiment of the present invention. Figure 2 This interaction may include:

[0081] 201. When detecting that the bare metal server 13 switches from the provision network to the service network, the cloud platform management device 11 performs network configuration of the service network on the physical switch connected to the bare metal server 13.

[0082] 202. The cloud platform management device 11 obtains the gateway address of the gateway device corresponding to the service network.

[0083] 203. The cloud platform management device 11 creates a first DHCP port of the service network by reusing the gateway address.

[0084] 204. In response to the creation operation of the first DHCP port, the DHCP server 12 creates a first DHCP service and runs the first DHCP service through the gateway address.

[0085] 205. The bare metal server 13 sends a first DHCP request corresponding to the service network to the DHCP server 12 through the physical switch configured corresponding to the service network.

[0086] 206 . The DHCP server 12 responds to the first DHCP request through the first DHCP service to allocate an IP address in the service network to the bare metal server 13 .

[0087] It should be noted that the bare metal server 13 does not have a host system installed before going online. However, the operation of the bare metal server 13 depends on the host system. Therefore, before connecting the bare metal server 13 to the business network, the host system must be deployed on the bare metal server 13. This host system deployment process can be implemented during the provisioning phase. To deploy the host system on the bare metal server 13, before connecting the bare metal server 13 to the business network, it is necessary to first connect the bare metal server 13 to the provisioning network and download the system image file corresponding to the host system through the provisioning network.

[0088] The provision network is a shared network. Before different users bring the bare metal servers 13 online to their respective deployed business networks, they can first connect each bare metal server 13 to the shared provision network.

[0089] Optionally, the process of connecting the bare metal server 13 to the provision network can be implemented as follows: the cloud platform management device 11 is configured to perform network configuration for the provision network on the physical switch in response to the bare metal server 13's online request; and a second DHCP port for the provision network is created. The DHCP server 12 is configured to create a second DHCP service in response to the creation of the second DHCP port. The bare metal server 13 is configured to send a second DHCP request corresponding to the provision network to the DHCP server 12 via the physical switch configured for the provision network. The DHCP server 12 responds to the second DHCP request via the second DHCP service to assign an IP address in the provision network to the bare metal server 13.

[0090] like Figure 3 The following is a signaling interaction diagram for connecting the bare metal server 13 to the provision network. Figure 3 This interaction may include:

[0091] 301. In response to the online request of the bare metal server 13, the cloud platform management device 11 performs network configuration of the provision network on the physical switch.

[0092] 302. The cloud platform management device 11 creates a second DHCP port of the provision network.

[0093] 303. In response to the creation operation of the second DHCP port, the DHCP server 12 creates a second DHCP service.

[0094] 304. The bare metal server 13 sends a second DHCP request corresponding to the provision network to the DHCP server 12 through the physical switch configured corresponding to the provision network.

[0095] 305 . The DHCP server 12 responds to the second DHCP request through a second DHCP service to allocate an IP address in the provision network to the bare metal server 13 .

[0096] In actual applications, users can create a bare metal server 13 through OpenStack and operate the bare metal server 13 online. When the bare metal server 13 online operation is detected, a bare metal server 13 online request can be generated accordingly. In response to the bare metal server 13 online request, the Neutron component in OpenStack can use the neutronserver service and the networkingodl tool to send the network configuration information of the provision network to the physical switch, so that the physical switch can complete the network configuration of the provision network based on the network configuration information.

[0097] The physical switch refers to the physical switch connected to the bare metal server 13. It is understood that in an actual network, multiple physical switches are interconnected. If you want to connect the bare metal server 13 to the network, you need to connect the bare metal server 13 to a physical switch, so that the network can be connected for the bare metal server 13.

[0098] The network configuration information sent to the physical switch may include configuration information for the physical switch access ports and overlay network configuration information. Overlay network configuration information may include interface-specific virtual local area networks (VLANs), aggregation configuration information, and virtual extensible local area network (VXLAN) configuration information.

[0099] Optionally, the cloud platform management device 11 can configure the physical switch by sending network configuration information to the controller, which then performs network configuration on the physical switch based on the received network configuration information. Furthermore, it should be noted that if the cloud platform management device 11 and the controller are considered as a whole, then the cloud platform management device 11 can also be considered to be performing network configuration on the physical switch.

[0100] By configuring the physical switch, after a DHCP request is sent from the bare metal server 13, the DHCP request can be broadcast to the DHCP server 12. Otherwise, the DHCP request cannot reach the DHCP server 12, and the DHCP server 12 cannot respond to the request, and thus cannot assign an IP address to the bare metal server 13.

[0101] A second DHCP port for the provision network can also be created in OpenStack. When the second DHCP port is created in OpenStack, the DHCP server 12 optionally creates a second DHCP server and a second namespace corresponding to the provision network, and then runs a second DHCP server in the second namespace. The DHCP server is used to respond to DHCP requests.

[0102] It's important to note that a namespace can be thought of as an isolated container and independent resource. It provides the operating environment for the DHCP server. In practice, different networks can be mapped to different namespaces. Traffic requesting different network IP addresses is processed in the corresponding namespace, isolating different networks from each other.

[0103] When the DHCP server 12 receives the second DHCP request from the bare metal server 13 , it can respond through the second DHCP server running in the second Namespace, thereby allocating an IP address in the provision network to the bare metal server 13 .

[0104] The following describes how to create a second DHCP port and run the second DHCP service.

[0105] In practice, the provision network's network address is required when creating a secondary DHCP port and running a secondary DHCP service. In the first option, you can obtain the provision network's IP address and create a secondary DHCP port or run a secondary DHCP service based on it. In the second option, you can obtain the gateway address of the provision network's gateway device and reuse it to create a secondary DHCP port or run a secondary DHCP service.

[0106] It is worth noting that if the second optional method is adopted, available IP addresses in the provision network can be saved for the provision network, that is, network resources of the provision network can be saved.

[0107] In some optional embodiments, the user can specify a system image file to be deployed to the bare metal server 13. The system image file can be stored on a Trivial File Transfer Protocol (TFTP) server. After the bare metal server 13 is connected to the provision network, the bare metal server 13 can optionally access the TFTP server using the assigned IP address of the provision network to download the system image file from the TFTP server.

[0108] Optionally, the bare metal server 13 can be used to: obtain a system image file specified by a user; and start the server in a local startup manner to run a host system corresponding to the system image file.

[0109] Specifically, after the bare metal server 13 downloads the user-specified system image file, it notifies the Ironic component in OpenStack. Ironic, through the baseboard management controller (BMC), configures the bare metal server 13 to boot locally. This allows the bare metal server 13 to boot locally, thereby running the host system corresponding to the system image file.

[0110] It is understood that after the bare metal server 13 completes the local startup operation, the provisioning phase is complete, and the bare metal server 13 can then be controlled to switch from the provision network to the service network. Optionally, the cloud platform management device 11 can also be configured to disconnect the bare metal server 13 from the provision network after detecting that the bare metal server 13 has completed the local startup. This can free up network resources in the provision network.

[0111] In some optional embodiments, the process of disconnecting the bare metal server 13 from the provision network can be specifically implemented as follows: Ironic notifies Neutron to delete the network configuration corresponding to the second DHCP port and the provision network in the physical switch. Accordingly, the DHCP server 12 deletes the second namespace.

[0112] As can be seen from the provisioning phase's operational flow, before actually connecting to the service network, a series of device interactions are required during the provisioning phase to connect the bare metal server 13 to the provisioning network and download the user-specified system image file through the provisioning network to complete the deployment of the system image file. Therefore, the execution of the provisioning phase takes a considerable amount of time.

[0113] Based on this, during the time between the creation of the bare metal server 13 and the switching of the bare metal server 13 from the provision network to the business network, if there are continuously cloud hosts online in the business network, then the online cloud hosts will occupy the available IP addresses of the business network. Among them, cloud hosts refer to virtual machines and other bare metal servers 13. If these cloud hosts completely exhaust the available IP addresses of the business network, then the subsequent online operation of the bare metal server 13 in the business network will be affected. Because the network address is required for certain links in the online operation of the bare metal server 13 in the business network. The technical solution provided by the embodiment of the present invention can ensure that after the bare metal server 13 is created, even if there are continuously cloud hosts online on the business network during the provision stage, the bare metal server 13 can be successfully online on the business network. The following will describe in detail the process of the bare metal server 13 switching from the provision network to the business network.

[0114] When it is detected that the bare metal server 13 has switched from the provisioning network to the business network, the cloud platform management device 11 performs network configuration of the business network on the physical switch connected to the bare metal server 13. Specifically, after detecting that the bare metal server 13 has completed the local startup operation, the Ironic component in Openstack can notify the Neutron component to configure the physical switch. Based on the neutronserver service, the Neutron component can use the networkingodl tool to send the network configuration information of the business network to the physical switch, so that the physical switch can complete the network configuration of the business network based on the network configuration information.

[0115] Next, you need to create the first DHCP port for the service network in OpenStack. Since creating the first DHCP port requires the service network's network address, if no available IP addresses exist in the service network, creating the first DHCP port using the IP address will fail. In this embodiment of the present invention, regardless of whether the service network still has available IP addresses, the first DHCP port is not created using a separate IP address. Instead, the first DHCP port is created by reusing the gateway address of the service network's gateway device.

[0116] Since the gateway address of the gateway device of the business network generally exists, creating the first DHCP port by reusing the gateway address can ensure that the first DHCP port can be successfully created. In addition, it should be noted that since the gateway address needs to be reused, the gateway address of the gateway device can also be obtained before creating the first DHCP port, and the gateway address can be reused after the gateway address is known. Specifically, the gateway address of the gateway device can be initially configured in the cloud platform management device 11, and the cloud platform management device 11 sends the gateway address to the controller, and then the controller configures the gateway address of the gateway device. Based on this, the gateway address of the gateway device is stored in the cloud platform management device 11, so the cloud platform management device 11 can directly obtain the gateway address of the gateway device locally.

[0117] When the first DHCP port is created in OpenStack, the DHCP server 12 may optionally create a first DHCP server and a first namespace corresponding to the service network, and then run the first DHCP server in the first namespace. The first DHCP server may be implemented based on DNSmasq (a compact and convenient tool for configuring DNS and DHCP, suitable for small networks, which provides DNS functionality and optional DHCP functionality).

[0118] It should be noted that the concepts of DHCP server and namespace are explained in the previous section describing the provision network. Their meanings and functions here are similar, so you can refer to the previous description and will not elaborate on them here.

[0119] It is worth noting that since the first DHCP service in the first namespace requires the network address of the service network, if no available IP address exists in the service network, the first DHCP service cannot be run normally using the IP address. In this embodiment of the present invention, the first DHCP service can be run by reusing the gateway address of the gateway device in the service network, thereby ensuring the normal operation of the first DHCP service.

[0120] The above method ensures the successful creation of the first DHCP port and the operation of the first DHCP service. Only when the first DHCP port and the first namespace are successfully created or operated can DHCP server 12 properly respond to the first DHCP request received from bare metal server 13, thereby ensuring that the IP address of the business network can be properly allocated to bare metal server 13, so that bare metal server 13 can successfully go online on the business network.

[0121] It's also worth noting that even if there are no available IP addresses in the business network, as long as the first DHCP port is successfully created and the first DHCP service is running, the business network's IP address can be properly assigned to the bare metal server 13. This is because when the bare metal server 13 is initially created, an IP address is already occupied in the business network. In other words, the business network reserves an IP address for the bare metal server 13 at the time of its creation, so the bare metal server 13 can obtain an IP address in the business network. In contrast, if there are no available IP addresses in the business network at the time of bare metal server 13 creation, the creation of the bare metal server 13 will fail, and the subsequent process of bringing the bare metal server 13 online will be unnecessary.

[0122] After creating the first Namespace and running the first DHCP server in the first Namespace, when the DHCP server 12 receives the first DHCP request from the bare metal server 13, the first DHCP server can respond to the first DHCP request with the gateway address, thereby allocating an IP address in the business network to the bare metal server 13.

[0123] In certain optional embodiments, because the first namespace in DHCP server 12 reuses the gateway address, traffic destined for the gateway address also reaches DHCP server 12, raising the question of how DHCP server 12 handles this traffic. This embodiment of the present invention provides a solution to this problem. Optionally, DHCP server 12 is configured to: receive a pending request; if the pending request is a first DHCP request corresponding to a service network, respond to the first DHCP request via the first DHCP service running in the first namespace; and if the pending request is not a first DHCP request corresponding to a service network, not process or discard the pending request.

[0124] In actual application, DHCP server 12 only processes services for itself, such as the first DHCP request corresponding to the service network. For other services that are not its own, it may not process or discard pending requests.

[0125] Specifically, the above process can be implemented through a flow table (OpenFlow). Optionally, the DHCP server 12 is used to: determine the operational behaviors corresponding to different pending requests based on the flow table. The flow table also specifies the operational behaviors corresponding to different pending requests; when the pending request is the first DHCP request corresponding to the service network, the operational behavior includes responding to the first DHCP request through the first DHCP service running in the first namespace; when the pending request is not the first DHCP request corresponding to the service network, the operational behavior includes not processing or discarding the pending request.

[0126] Before actually processing the pending request, it is necessary to identify whether the pending request corresponds to the first DHCP request of the service network. Based on this, the DHCP server 12 can also be used to: determine whether the pending request is the first DHCP request corresponding to the service network based on the matching domain in the flow table.

[0127] The matching domain can be used to distinguish different traffic flows.

[0128] In the flow table, different operational behaviors are set for different pending requests. For example, if a pending request is identified as the first DHCP request for a service network, the first DHCP service running in the first namespace can respond to the first DHCP request based on the corresponding operational behavior recorded in the flow table. If a pending request is identified as not the first DHCP request for a service network, it indicates that DHCP server 12 does not need to process it. Therefore, the pending request can be ignored or discarded based on the corresponding operational behavior recorded in the flow table.

[0129] In addition, in some optional embodiments, the cloud platform management device 11 can also be used to delete the network configuration of the service network in the physical switch in response to the event of deleting the first DHCP port. The DHCP server 12 can also be used to delete the first namespace.

[0130] The event of deleting the first DHCP port may include deleting the first DHCP port in Openstack, deleting the service network by a user, and the like.

[0131] When the event of deleting the first DHCP port is detected, the network configuration of the service network and the first Namespace in the physical switch can be deleted accordingly, thereby releasing certain network resources.

[0132] By adopting the present invention, regardless of whether there are any available IP addresses in the business network, a separate IP address is not used to create the first DHCP port and run the first DHCP service. Instead, the first DHCP port is created and the first DHCP service is run by reusing the gateway address of the gateway device of the business network. Since the gateway address of the gateway device of the business network generally exists, creating the first DHCP port and running the first DHCP service by reusing the gateway address can ensure that the first DHCP port can be successfully created and the first DHCP service can be successfully run. When the first DHCP port and the first DHCP service can be successfully created or run, the DHCP server can normally respond to the first DHCP request received from the bare metal server, thereby ensuring that the IP address of the business network can be normally allocated to the bare metal server. In this way, the bare metal server can successfully go online on the business network without failure due to the lack of available IP addresses in the business network.
