Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent computing centers, in particular to an address allocation method and device and related equipment. BACKGROUND

[0002] In the RoCE (RDMA (Remote Direct Memory Access) over Converged Ethernet) VLAN (Virtual Local Area Network) networking of an intelligent computing center, due to the large scale of server network cards, the IP address allocation and management of servers is often a complex task, and the system usually uses DHCP (Dynamic Host Configuration Protocol) technology to allocate addresses for server network cards. In order to support high reliability access, the storage network of the intelligent computing center needs to use M-LAG (Multichassis Link Aggregation Group) networking access, and under M-LAG access, the conventional DHCP mode cannot be used, and DHCP relay technology needs to be used. In the tenant scenario, the size of the tenant network segment cannot be known in advance, and can only be specified when the tenant is created, so it is not possible to pre-configure the DHCP relay server, and thus under the RoCE VLAN networking, the configuration of the DHCP server needs to be performed manually during the process of the tenant being online or offline, which brings difficulties to the operation and maintenance of users and introduces the possibility of errors.

These terms are only used to distinguish one type of information from another.

In addition, depending on the context, the word "if" used can be interpreted as "when" or "in response to determining" or "in response to ascertaining".

[0045] Under the RoCE VLAN networking of the intelligent computing center, due to the large scale of the server network card, the IP address allocation and management of the server is often a complex work, and the system usually uses the DHCP technology to allocate addresses for the server network card. In order to support high reliability access, the storage network of the intelligent computing center needs to use M-LAG networking access, and under the M-LAG access, the conventional DHCP mode cannot be used, and the DHCP relay technology needs to be used.

[0046] Specifically, under the M-LAG networking scenario, if the DHCP mode is used, the DHCP Server is respectively deployed on the access equipment included in the M-LAG system, and the computing server double-standard access M-LAG system, which may cause address allocation error / conflict. Therefore, the DHCP relay technology needs to be used, a third-party DHCP relay Server is deployed, and then in the multi-tenant scenario, the size of the network segment required by the tenant cannot be predicted in advance, and can only be determined when the tenant is created, so it is impossible to pre-configure the DHCP relay Server, and under the RoCE VLAN networking, the configuration of the DHCP relay Server needs to be manually performed in the process of the tenant online / offline, which brings difficulties to the operation and maintenance of the user and introduces the possibility of error.

[0047] For example, the current address allocation process is as follows:

[0048] 1. Assign HOST1 and HOST2 two computing nodes to the tenant;

[0049] 2. The network card 1~network card 8 of the computing node is used as a parameter network, each network card has its own independent network segment, the DHCP server is respectively enabled on leaf1~leaf8, and the address pool of the DHCP is dynamically specified using the parameter network segment when the tenant is created;

[0050] 3. The network card 9~network card 10 on the computing node is used as a storage network card, and is used for communication with the storage service side, the network card 9 and the network card 10 form a bond port, and are respectively connected to two storage clients leafs to form an M-LAG system;

[0051] 4. Since the storage network card uses the M-LAG mode to access, if the same DHCP mode as the parameter network is used, the DHCP server is respectively enabled on leaf9 and leaf10, which will cause DHCP allocation confusion, so the DHCP relay mode is needed;

[0052] 5. The DHCP relay method requires the deployment of an additional DHCP server, and then forwards the DHCP requests of the storage network card to the DHCP server. Since this DHCP server is usually deployed independently, it cannot be dynamically operated during the tenant's online process and can only be configured manually. As a result, under RoCE VLAN networking, the server's M-LAG access network card cannot automatically complete the IP address configuration and requires manual intervention, making it impossible to complete the entire process fully automatically.

[0053] In practical applications, tenant networks are dynamically changing and can only be determined when a tenant comes online. Therefore, it is impossible to pre-configure the address pool of the tenant's storage network on the DHCP server. Manually configuring the storage network segment on the DHCP server makes it impossible to achieve fully automatic tenant online / offline status. Since the server's address is managed on a third-party DHCP server, it is not easy for the cloud side and the controller to know the specific usage of IP addresses within the network segment, which is not conducive to the overall network operation and maintenance. Storage networks usually have the requirement of fixed and unchanging IP addresses, and DHCP relay cannot guarantee that the client will be assigned the same IP address every time, which may bring abnormalities to the storage operation. DHCP relay technology requires additional server deployment, which increases the consumption of client hardware and software resources.

[0054] Based on the above points, it can be seen that DHCP relay technology is not suitable for tenant scenarios where network segments are dynamically added or deleted.

[0055] To address the aforementioned issues, this application provides a scheme for allocating addresses to the computing servers corresponding to tenants based on a controller. This scheme enables automated tenant online / offline status while ensuring that the IP addresses of each tenant's computing server are fixed, thus meeting users' requirements for fixed IP addresses.

[0056] For example, see Figure 1 The diagram shown is a detailed flowchart of an address allocation method provided in an embodiment of this application. This method is applied to a controller, where agent programs are deployed on each access device managed by the controller, and a communication link is established between the controller and the agent programs of each access device. The method includes the following steps:

[0057] Step 100: Determine the tenant information of the newly created tenant, wherein the tenant information includes the target computing server information assigned to the tenant and the target tenant network segment information assigned to the tenant.

[0058] In the embodiment of the present application, the target access device includes a first access device and a second access device, and the first access device and the second access device constitute a cross-device link aggregation system; the target computing server includes at least one computing server, and a target network card of each target computing server includes a first network card and a second network card, wherein the first network card and the second network card constitute a logical virtual interface, the first network card accesses the first access device, and the second network card accesses the second access device.

[0059] That is, the controller is in a pipe access device group M-LAG system, for example, see Figure 2 As shown in the figure, a networking schematic diagram provided by the embodiment of the present application, the target access device includes access device 1 (such as Leaf-1) and access device 2 (such as Leaf-2), Leaf-1 and Leaf-2 constitute an M-LAG system, assuming that the target computing servers allocated to the target tenant are server 1 and server 2, then the network card 1 of server 1 accesses Leaf-1 (such as the downlink interface 1 of Leaf-1), the network card 2 of server 1 accesses Leaf-2 (such as the downlink interface 1 of Lefa-2), the network card 1 of server 2 accesses Leaf-1 (such as the downlink interface 2 of Leaf-1), and the network card 2 of server 2 accesses Leaf-2 (such as the downlink interface 2 of Leaf-2). The network card 1 and the network card 2 of server 1 constitute a virtual logical port 1, such as a bond port, and the virtual logical port double rules access the M-LAGA system composed of access device 1 and access device 2; similarly, the network card 1 and the network card 2 of server 2 also constitute a virtual logical port 2, and the virtual logical port double rules access the M-LAGA system composed of access device 1 and access device 2.

[0060] In the embodiment of the present application, the server can be a computing server in an intelligent computing network, the access device can be a storage client Leaf in the intelligent computing network, and the storage network of the intelligent center requires the access device to constitute an M-LAG system. When allocating IP addresses for the storage network card of the computing server, in order to avoid IP address allocation errors / conflicts, the conventional DHCP mode cannot be used. Only the DHCP relay mode can be used, and in the tenant scenario of the intelligent center, in order to realize automatic planning of the tenant network and automatic online / offline of the tenant, the DHCP relay mode no longer meets the scene requirements.

[0061] In the embodiment of the present application, when determining the tenant information of the newly created tenant, a preferred implementation manner is:

[0062] receive the tenant information of the newly created tenant sent by the cloud, wherein the tenant information comprises the tenant name of the newly created tenant, the target computing server information allocated to the tenant and the target tenant network segment information allocated to the tenant; determine the target computing server allocated to the tenant and the target tenant network segment allocated to the tenant based on the tenant information.

[0063] That is, when creating a tenant, the administrator determines the number of computing servers required by the tenant, and allocates the target computing server satisfying the requirement of the tenant to the newly created tenant. Further, the administrator can also determine the size of the tenant network segment required by the tenant according to the number information of the target computing server, so as to allocate the target network segment satisfying the requirement of the tenant to the tenant in the cloud. Finally, the cloud sends the information of the newly created tenant to the controller.

[0064] In the embodiment of the application, if the tenant information does not comprise the tenant network segment information allocated to the newly created tenant, when determining the tenant network segment information of the newly created tenant, a preferable implementation manner is:

[0065] determining an available network segment satisfying a preset condition from a preset address pool, and allocating the available network segment as the target tenant network segment to the newly created tenant.

[0066] That is, if the administrator does not allocate the target tenant network segment to the newly created tenant in the cloud, the controller can determine an available network segment satisfying the requirement of the tenant from the preset address pool in the local based on the number of the target computing server allocated to the tenant, and determine the available network segment as the target tenant network segment allocated to the tenant.

[0067] Step 110: instruct the target access device accessed by the target computing server to create a logical virtual interface, and set the IP address of the logical virtual interface as the gateway address of the target tenant network segment.

[0068] After the controller determines the target computing server allocated to the newly created tenant, determines the access device accessed by the to-be-configured network card of the target computing server, and determines the tenant network segment of the tenant, the controller allocates the subnet gateway according to the tenant storage network, instructs the access device accessed by the to-be-configured network card of the target computing server to create a logical virtual interface (such as a VLAN interface), and configures the IP address of the VLAN interface as the gateway IP address of the tenant network segment of the tenant after determining that the access device creates the corresponding VLAN interface.

[0069] Step 120: allocate a target IP address to the target computing server from the target tenant network segment.

[0070] Then, the target network card of the target computing server needs to be allocated with an IP address. In actual application, two network cards of the target computing server are connected to the M-LAG system, that is, two network cards of one target computing server form a logical virtual interface, and the logical virtual interface is connected to the M-LAG system in a dual mode, so that the logical virtual interface is allocated with an IP address.

[0071] In step 130, an address allocation instruction carrying the target IP address is sent to the target computing server through a communication link between the agent program and the target server, so that the target computing server configures the target network card based on the IP address carried by the address allocation instruction, wherein the target network card is a network card connected to the target access device.

[0072] Specifically, the controller selects an available IP address from the tenant network segment as the target IP address allocated to the target computing server, and communicates with the agent program deployed on the target computing server to send an address allocation instruction carrying the target IP address, so that the target computing server configures the target IP address carried as the IP address of the logical virtual interface after receiving the address allocation instruction.

[0073] For example, assuming that the target computing server includes server 1 and server 2, the network card 1 and the network card 2 of the server 1 form a logical virtual interface 1, and the network card 1 and the network card 2 of the server 2 form a logical virtual interface 2, the controller allocates an available IP1 from the tenant network segment to the server 1, and allocates an available IP2 from the tenant network segment to the server 2, then the controller sends the available IP1 carried in the address allocation instruction to the agent program of the server 1 through a communication link 1 between the agent program and the server 1, and the server 1 configures the IP address of the logical virtual interface 1 as IP1; similarly, the controller sends the available IP2 carried in the address allocation instruction to the agent program of the server 2 through a communication link 2 between the agent program and the server 2, and the server 2 configures the IP address of the logical virtual interface 2 as IP2.

[0074] Further, in the embodiment of the present application, after allocating the IP address to the target network card of the target computing server corresponding to the newly created tenant, the mapping relationship between each target network card and the IP address allocated thereto is maintained; when the upper limit of the target network card of the target computing server is detected, it is judged whether the target IP address corresponding to the target network card is maintained locally, if yes, the target IP address is allocated to the target network card; otherwise, an IP address is allocated to the target network card from the tenant network segment corresponding to the target tenant corresponding to the target computing server.

[0075] That is, when the tenant is offline and then online, or the target server is recovered / restarted, and the target network card is online, first, it is judged whether the target IP address corresponding to the target network card is maintained locally. If it exists, the maintained IP address is directly allocated to the target network card. If it does not exist, the IP address is allocated to the target network card again. It is ensured that the IP of the target network card of the target computing server allocated to the tenant is fixed during the process from creation to deletion of the tenant, and the IP change caused by network abnormity is avoided, so as to affect the business operation.

[0076] Based on the same inventive concept as the above-mentioned embodiments, an exemplary structure of an address allocation device provided by the embodiments of the present application is shown in FIG. 1, which is applied to a controller.
