Description

Technical Field

[0001] This application relates to the field of cloud computing technology, and in particular to a method, apparatus and equipment for mounting cloud disks on a bare metal server. Background Technology

[0002] In the current cloud computing field, the use of cloud disks on virtual machines has become very common. More and more users, having experienced the advantages of cloud disks, also expect bare-metal servers to be able to use them. Due to the high reliability, rapid creation, dynamic expansion, data backup and rollback capabilities of cloud disks, and their ability to be emulated as PCIe disks for virtual machines by virtual operating system emulators (QuickEMUlator, QEMU), the use of cloud disks on virtual machines has become mainstream in the cloud.

[0003] However, bare metal is essentially a physical server. Without external hardware assistance, it cannot simulate a PCIe hard drive as a cloud disk. This limitation means that when bare metal is used in a cloud disk, either the security is unreliable or the performance is very poor.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0074] Bare metal is essentially a physical server. Without external hardware assistance, it's impossible to simulate a PCIe hard drive as a cloud disk. This limitation means that using cloud disks on bare metal is either prohibitively expensive, unreliable in terms of security, or has poor performance. Therefore, current technology cannot simultaneously meet the needs of bare metal using cloud disks while ensuring low cost, high security, and high performance.

[0075] To address the aforementioned issues, the technical concept of this application is as follows: By establishing a network proxy among the computing service node, cloud disk management service node, and cloud disk storage pool node, and determining cloud disk-related information, the bare metal server can directly access the cloud disk storage pool node. This path is the shortest, avoiding network traffic bottlenecks, improving the throughput performance of cloud disk data, avoiding high load on network platform nodes, avoiding impact on virtual machine network bandwidth, improving cluster stability, and ensuring high performance. Furthermore, by isolating the tenant network and the OpenStack cluster network through the network proxy, the security of user data and the security of the cloud platform management plane are guaranteed.

[0076] refer to Figure 1 , Figure 1This is a schematic diagram illustrating a scenario for mounting a cloud disk on a bare metal server according to an embodiment of this application. The scenario may include a management environment computing node, a management environment cloud disk storage pool node, and bare metal nodes. The management environment computing node may include computing service nodes (e.g., Nova service) and cloud disk management service nodes (e.g., Cinder volume management service). The computing service nodes and cloud disk management service nodes can be deployed on the same server or on different servers; no specific limitation is made here. The management environment cloud disk storage pool node may include storage network proxy service sub-nodes (e.g., bm-storage-agent service) and service sub-nodes for providing cloud disks (e.g., gateway service, i.e., gw service). The bare metal nodes include bare metal servers such as bare metal node 1 and bare metal node 2.

[0077] Specifically, for the computing nodes in the management environment:

[0078] a) Nova service

[0079] i. Receive the user's request to mount the cloud disk (referring to the first request to mount the cloud disk);

[0080] ii. Send a request to the cloud disk management node (referring to the cloud disk management service node) to prepare the cloud disk and the cloud disk attribute settings (referring to the second cloud disk mount request);

[0081] iii. Send the prepared cloud disk information to the bare metal (referring to the bare metal server) and request to mount the cloud disk (referring to the third cloud disk mount request);

[0082] iv. Notify the user that the cloud drive has been successfully mounted;

[0083] b) Cinder Volume Management Service

[0084] i. Receive cloud disk mounting requests from the Nova service (referring to the second cloud disk mounting request);

[0085] ii. Generate the cloud drive connection username (i.e., username) and password;

[0086] iii. Request the gateway service (used to provide cloud disk service sub-nodes) of the backend storage pool (referring to the cloud disk storage pool node) to prepare the iSCSI volume;

[0087] iv. Request the bm-storage-agent (storage network agent service sub-node) program of the backend storage pool to prepare the tenant's cloud disk network agent;

[0088] For the management environment cloud disk storage pool node.

[0089] a) bm-storage-agent service

[0090] Prepare a network proxy for the tenant's cloud disk based on the tenant's network information.

[0091] b) GW service

[0092] Create an iSCSI device (cloud disk), inject the initiator ID (bare metal characteristic identifier, which refers to the identification information of the bare metal server), and inject the username and password of the cloud disk.

[0093] c) Tenant cloud disk network proxy space

[0094] Network proxy space is a proxy space allocated on the storage pool nodes. Each cloud disk network corresponds to one proxy space (Linux network namespace), and its necessity and advantages are as follows:

[0095] i. Ensure tenant isolation. Different tenants use different proxy spaces, which are independent of each other and do not affect each other. Different tenants can use the same IP address range and IP address when mounting iSCSI cloud disks.

[0096] ii. Ensure data security.

[0097] Because the proxy spaces are independent of each other, it ensures that tenant A cannot access tenant B's cloud disk, thus preventing data snooping and network attacks.

[0098] iii. Ensure the security of the management cluster.

[0099] Tenants access cloud disks through a proxy, preventing users from directly accessing local resources on the storage pool server and thus avoiding attacks on the entire cloud platform by malicious users.

[0100] For bare metal nodes

[0101] The bm-guest-agent (client or user client that mounts the cloud disk) service on the bare metal node is used to receive cloud disk information from the Nova service, including the network proxy address, the target and portal of the iSCSI cloud disk's LUN device, and information such as username and password.

[0102] Regarding the internet

[0103] a) Management network. This is the management plane network of the OpenStack cloud platform, used for managing cloud resources. User bare-metal instances are not connected to this network.

[0104] b) Service Network / Tenant Network / Computing Network. These three terms all refer to the service network. It is the network used by users for normal internet access and production activities. Users only have the service network and can only access networks on the service network that are in the same isolated area as them.

[0105] Therefore, this application connects to the business network through storage nodes (referring to cloud disk storage pool nodes) and runs a network proxy management program, enabling bare metal servers to directly access the storage pool servers via a Layer 2 physical network link. This path is the shortest, avoiding network traffic bottlenecks and improving the throughput performance of cloud disk data; it avoids high load on network platform nodes; it avoids impacting virtual machine network bandwidth, improves cluster stability, solves the problem of poor performance, and ensures high performance. By isolating the tenant network and the OpenStack cluster network through the network proxy, it ensures the security of user data and the security of the cloud platform management plane.

[0106] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0107] See Figure 2 As shown, Figure 2 This is a flowchart illustrating a method for mounting a cloud disk on a bare metal server, as provided in an embodiment of this application. The method is applied to a computing service node and includes:

[0108] S201. Receive a first cloud disk mounting request, wherein the first cloud disk mounting request includes the identity information of the cloud disk and the identification information of the bare metal server.

[0109] S202. Based on the first cloud disk mounting request, determine the cloud disk mounting information and send a second cloud disk mounting request to the cloud disk management service node. The second cloud disk mounting request includes cloud disk mounting information, which includes connector ID and storage network subnet ID.

[0110] S203. Receive cloud disk related information and network proxy address sent by the cloud disk management service node, wherein the cloud disk related information is determined by the cloud disk storage pool node, and the network proxy corresponding to the network proxy address is created by the cloud disk storage pool node.

[0111] S204. Based on the identification information of the bare metal server, send a third cloud disk mounting request to the corresponding bare metal server, so that the bare metal server, based on the cloud disk related information and network proxy address in the third cloud disk mounting request, sends a cloud disk mounting success message to the computing service node after the cloud disk is successfully mounted.

[0112] In this embodiment, taking Nova-compute (or Nova Compute Service) as the computing service node and Cinder as the cloud disk management service node as an example, the user can send a cloud disk mounting request to Nova-compute through the user console (e.g., a webpage). Nova-compute receives the cloud disk mounting request from the user and determines the cloud disk mounting information based on the cloud disk's identity information (e.g., the cloud disk ID) and the bare metal server's identification information in the cloud disk mounting request. The cloud disk mounting information includes the connector ID and the subnet ID of the storage network (i.e., subnet_uuid). Nova-compute sends the cloud disk mounting information to Cinder, and Cinder prepares the cloud disk connection information based on the cloud disk mounting information. The cloud disk storage pool node then determines the cloud disk information, including cloud disk-related information and the network proxy address. Nova-compute sends a cloud disk mount request to the corresponding bare metal server based on the bare metal server's identification information. After the cloud disk is successfully mounted, the bare metal server sends a message to Nova-compute indicating that the cloud disk has been successfully mounted, based on the cloud disk information and network proxy address in the mount request.

[0113] The method for mounting cloud disks on bare metal servers provided in this embodiment enables bare metal servers to directly access cloud disk storage pool nodes by establishing a network proxy among computing service nodes, cloud disk management service nodes, and cloud disk storage pool nodes, and determining cloud disk-related information. This path is the shortest, avoiding network traffic bottlenecks, improving cloud disk data throughput performance, avoiding high load on network platform nodes, avoiding impact on virtual machine network bandwidth, improving cluster stability, and ensuring high performance. By isolating the tenant network and the OpenStack cluster network through the network proxy, the security of user data and the security of the cloud platform management plane are guaranteed.

[0114] In one possible design, determining the cloud disk information based on the first cloud disk mounting request includes:

[0115] Determine the connector ID based on the identification information of the bare metal server;

[0116] Based on the identity information of the cloud disk, query the subnet ID of the storage network used by the bare metal server to mount the cloud disk.

[0117] In this embodiment, Nova-compute determines the connector id based on the bare metal server's identification information, and simultaneously queries the subnet_uuid of the cloud disk network used by the bare metal server.

[0118] In one possible design, sending a third cloud disk mount request to the corresponding bare metal server based on the bare metal server's identification information includes:

[0119] Create a temporary interface on the computing network of the computing service node;

[0120] The temporary interface is bound to the IP address under the tenant's cloud disk network and labeled with the virtual LAN tag of the cloud disk network, so as to connect with the client that mounts the cloud disk on the corresponding bare metal server.

[0121] Send a third cloud disk mounting request to the client that has mounted the cloud disk.

[0122] In this embodiment, nova (i.e., Nova-compute) sends cloud disk connection information to the bm-guest-agent in the bare metal system. Specifically, since the computing network of the management environment compute node is a trunk port, in order to ensure network connectivity with the bare metal system, a temporary interface needs to be created on this network port. This interface is bound to an IP address under the tenant cloud disk network, and the VLAN tag of this network is also added, so that the nova service can connect to the bm-guest-agent service of the bare metal node; the volume connection information (here referring to the cloud disk connection information) is sent to the bm-guest-agent of the bare metal node.

[0123] In one possible design, after sending the third mount cloud disk request to the corresponding bare metal server, the method further includes:

[0124] The cloud disk mounting success message was received from the bare metal server.

[0125] A message indicating successful mounting of the cloud disk will be sent to the user console.

[0126] In this embodiment, the agent within the bare-metal node connects to the agent on the storage node via the iSCSI protocol based on the volume connection information, thus establishing a cloud disk connection. Once the cloud disk connection is complete, Nova returns the result to the user.

[0127] For example, in combination Figure 3 As shown, the implementation process of the method for mounting a cloud disk on a bare metal server in this embodiment is as follows:

[0128] 1. User issues cloud disk mounting operation.

[0129] II. Preparation for Nova-compute to process cloud disks.

[0130] a) Received a user's request to mount the cloud disk. This request will contain information about the cloud disk (referring to the cloud disk's identity information, such as its ID) and the bare metal identification information;

[0131] b) Obtain the connector id based on the bare metal's identification information, and simultaneously query the subnet_uuid of the cloud disk network used by the bare metal;

[0132] c) Send the above information to Cinder, and Cinder will prepare the cloud drive connection information.

[0133] III. Cinder prepares cloud drive connection information.

[0134] a) Cinder receives the mounted cloud disk information from nova and creates a username and password based on the connector ID and the cloud disk ID;

[0135] b) Send a request to the GW service of the storage pool node (i.e., the cloud disk storage pool node) to inject the username, password and bare metal identity into the cloud disk, and at the same time get the cloud disk connection information (portal, target, lun) returned by the GW service.

[0136] c) Send the subnet_uuid information from nova to the bm-storage-agent service of the storage pool node to create a tenant cloud disk network agent.

[0137] IV. Creating a Network Proxy using Bm-storage-agent

[0138] a) Based on the subnet UUID, determine the user's network and IP address, and create a network proxy to ensure that the bare metal can access the network proxy;

[0139] b) Return the network proxy address to Cinder.

[0140] 5. Cinder returns cloud drive connection information, network proxy information, etc. to Nova.

[0141] 6. Nova sends cloud disk connection information to bm-guest-agent in the bare metal.

[0142] a) Since the compute network of the management environment compute node is a trunk port, to ensure network connectivity with the bare metal system, a temporary interface needs to be created on this interface. This interface is bound to an IP address from the tenant cloud disk network, and a VLAN tag for that network is added. This allows the Nova service to connect to the bm-guest-agent service on the bare metal node.

[0143] b) Send the volume connection information to the bm-guest-agent of the bare metal node.

[0144] 7. The agent within the bare metal node connects to the agent on the storage node via the iSCSI protocol based on the volume connection information, thereby enabling cloud disk connection.

[0145] 8. Once the cloud drive connection is complete, nova will return the results to the user.

[0146] Therefore, this application connects to the business network through storage nodes (referring to cloud disk storage pool nodes) and runs a network proxy management program, enabling bare metal servers to directly access the storage pool servers via a Layer 2 physical network link. This path is the shortest, avoiding network traffic bottlenecks and improving the throughput performance of cloud disk data; it avoids high load on network platform nodes; it avoids impacting virtual machine network bandwidth, improves cluster stability, solves the problem of poor performance, and ensures high performance. By isolating the tenant network and the OpenStack cluster network through the network proxy, it ensures the security of user data and the security of the cloud platform management plane.

[0151] The computing service node sends the cloud disk-related information and the network proxy address to the computing service node, so that the computing service node sends a third cloud disk mount request to the corresponding bare metal server according to the bare metal server's identification information. The bare metal server is used to send a cloud disk mount success message to the computing service node after the cloud disk is successfully mounted, based on the cloud disk-related information and network proxy address in the third cloud disk mount request.

[0158] A request to provide a cloud disk network proxy is sent to the storage network proxy service sub-node in the cloud disk storage pool node, so that the storage network proxy service sub-node determines the storage network to which the user belongs based on the subnet ID of the storage network, creates a network proxy based on the storage network to which the user belongs, and feeds back the network proxy address corresponding to the network proxy to the cloud disk management service node.

[0159] This application connects to the business network via storage nodes (referring to cloud disk storage pool nodes) and runs a network proxy management program. This allows bare metal servers to directly access the storage pool servers through a Layer 2 physical network link. This path is the shortest, avoiding network traffic bottlenecks and improving the throughput performance of cloud disk data. It also avoids high load on network platform nodes, prevents impact on virtual machine network bandwidth, improves cluster stability, solves performance issues, and ensures high performance. By isolating the tenant network and the OpenStack cluster network through the network proxy, it ensures the security of user data and the security of the cloud platform management plane.

Cinder returns the cloud disk connection information and network proxy information to Nova. Nova sends the cloud disk connection information to bm-guest-agent in the bare metal. The agent in the bare metal node connects to the storage node's proxy via the iSCSI protocol based on the volume connection information, thus establishing the cloud disk connection. After the cloud disk connection is complete, Nova returns the result to the user.

[0168] In this embodiment, the network proxy for the storage pool node is as follows:

[0169] 1. Create a tenant network proxy space based on the network identifier sent by Cinder; this is a Linux namespace.

[0170] 2. Call the SDN controller to allocate a proxy VLAN interface for the tenant network of the storage pool node, and assign a tenant service network IP address to that interface, such as... Figure 1 Tenant A's cloud storage address is 192.168.0.200 / 24.

[0171] Third, place the proxy VLAN interface in the network proxy space. In this way, the traffic of users accessing the cloud disk will be directly imported into this namespace.

[0172] IV. Create vethpair device pairs (e.g.) Figure 1 The device pairs are phy-vlan100 / vlan100-phy and phy-vlan200 / vlan200-phy. One end of each device pair is located in the proxy space, and the other end is located locally on the storage pool server, used to connect the proxy space and the local storage pool.

[0173] 5. Within the proxy space, configure routing rules and set up network forwarding via iptables.

[0174] Therefore, this application connects to the business network through storage nodes (referring to cloud disk storage pool nodes) and runs a network proxy management program, enabling bare metal servers to directly access the storage pool servers via a Layer 2 physical network link.
