Description

Technical Field

[0001] This invention relates to the field of distributed block storage, and more specifically to a method and system for using distributed block storage on a bare metal server. Background Technology

[0002] Bare metal servers combine the advantages of physical machines and cloud servers, enabling rapid and automated delivery and convenient operation and maintenance management. Bare metal servers feature physical isolation, providing high security. Bare metal servers offer the same computing performance as physical machines, making them capable of handling virtualization applications, high-IO applications, high-performance computing, and other business applications, meeting the high performance and stability requirements of core application scenarios.

[0003] Traditional bare-metal machines are equipped with a certain number of hard drives for storage. The storage capacity and performance often fail to meet business needs. Replacing or adding hard drives is one way to improve performance, but this operation is costly and inconvenient. Furthermore, since data is stored locally on these hard drives, hard drive failure can lead to data corruption and loss, resulting in low data security.

[0004] After the bare metal of a traditional cloud resource pool is delivered, the use of block storage often requires manual operation of the machine to mount and unmount the block storage, which is complex and has high maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide a method for using distributed block storage on a bare metal server to improve the efficiency of delivering bare metal instances using block storage;

[0006] To address the aforementioned technical problems, this invention provides a method for using distributed block storage on a bare metal server, comprising the following steps:

[0007] Obtain HBA card information for the bare metal server;

[0008] Register the bare metal server on the ironic service based on the HBA card information;

[0009] Generate an Ironicnova configuration file based on the device status information of the bare metal server;

[0010] Install the bare metal server's image agent and Ironicnova configuration file onto the control node.

[0011] Preferably, based on the HBA card information, a bare metal server is registered on the ironic service, specifically including the following steps:

[0012] Based on the HBA card information, bare metal servers are registered in batches on the ironic service via ironicvolume-connector.

[0013] Preferably, the Ironicnova configuration file includes nova-api service information.

[0014] Preferably, the nova-api service information includes nova-compute service information and ironic driver information.

[0015] Preferably, the HBA card information includes the iqn number of the iSCSI block storage service.

[0016] The present invention also provides a system for bare metal servers using distributed block storage, comprising:

[0017] The acquisition module is used to acquire HBA card information of the bare metal server;

[0018] The registration module is used to register bare metal servers on the ironic service based on HBA card information;

[0019] The configuration file generation module is used to generate Ironicnova configuration files based on the device status information of the bare metal server.

[0020] The installation module is used to install the bare metal server's image agent and Ironicnova configuration file to the control node. Compared with the prior art, the advantages of this invention are:

[0021] After enhancing the ironic driver, the existing novavolume-attach interface can be used to mount / unmount volumes planned for use on bare metal within the bare metal instance in real time.

[0022] Bare metal block storage relies on automatic network configuration after the bare metal instance is deployed. This network includes a management network and a storage network. The management network controls nodes to remotely invoke services within the bare metal instance to perform corresponding block storage operations. The storage network connects to iSCSI block storage.

[0023] For bare metal machines with HBA cards, the HBA card wwnn and wwpn numbers need to be collected in batches and registered in batches before delivery to the cloud environment. This registration is used for FC block storage configuration by the backend storage when the machines are mounted.

[0024] Once the bare metal instance is deployed and the management network and storage network are successfully configured, the cloud management platform can be used to mount / unmount iSCSI block storage and FCSAN storage services for the bare metal instance, providing high-performance distributed block storage and significantly improving the efficiency of delivering block storage to the bare metal instance.

[0025] Specifically:

[0026] 1) Enables bare metal machines to use iSCSI distributed block storage and FCSAN storage.

[0027] 2) Improved the automation level of bare metal resource delivery in the cloud computing platform, solving the problem that native OpenStack cannot manage bare metal block storage.

[0028] 3) Reduce the workload of maintenance personnel and improve the delivery efficiency of bare metal block storage. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail as follows:

[0035] like Figure 1As shown, the present invention provides a method for using distributed block storage on a bare metal server, comprising the following steps:

[0036] Obtain HBA card information for the bare metal server;

[0037] Register the bare metal server on the ironic service based on the HBA card information;

[0038] Generate an Ironicnova configuration file based on the device status information of the bare metal server;

[0039] Install the bare metal server's image agent and Ironicnova configuration file onto the control node.

[0040] In a preferred embodiment, registering a bare metal server on the ironic service specifically includes the following steps:

[0041] Batch registration is performed using ironicvolume-connector.

[0042] In a preferred embodiment, the HBA card information includes the iqn number of the iSCSI block storage service;

[0043] In this embodiment, the iqn number of the iSCSI block storage service is the UUID generated when registering the node. Ensuring uniqueness means that the block storage can only be mounted by this bare metal machine, thus avoiding security issues.

[0044] In a preferred embodiment, installing the bare metal server's image agent onto the control node specifically includes the following steps:

[0045] Install the bare metal server's image agent onto the control node using the volume service agent.

[0046] In a preferred embodiment, the Ironicnova configuration file includes nova-api service information.

[0047] In a preferred embodiment, the nova-api service information includes nova-compute service information and ironic driver information.

[0048] To better illustrate the technical effects of the present invention, the present invention provides the following specific examples to illustrate the above technical process:

[0049] This example demonstrates a method for using distributed block storage on a bare-metal server, which includes the following steps:

[0050] 1) Obtain the HBA card information of the bare metal server; register the bare metal server on the ironic service based on the HBA card information;

[0051] 2) The cloud platform sends a Nova volume operation request to the bare metal management module;

[0052] 3) The bare metal management module distinguishes between virtual machines and bare metal instances based on Nova volume operation requests;

[0053] 4) Deploy OpenStack enhancement code;

[0054] The code deployment involves the nova-api service on the control node, the nova-compute service on the ironic compute node, and the ironic driver for the compute service. After deployment, restart the relevant services.

[0055] 5) Deploy the volume service client to the control node;

[0056] Multi-node deployment avoids service unavailability caused by single-node failure.

[0057] 6) Install the bare metal server's image agent onto the control node using the volume service agent;

[0058] The image agent and volume service client are installed in the same way. The volume service agent is installed and enabled when creating the bare metal base image. The service is volume-attachd-agent. The agent will start automatically after the bare metal instance is successfully deployed and the network is ready, connect to the RabbitMQ cluster of the public service node, and wait for the control node to make a remote volume service call.

[0059] 7) Configure the Ironicnova configuration file on the control node.

[0060] 8) Using bare metal volume services through the volume service client:

[0061] Plan separate storage pools (iSCSI block storage and FCSAN storage) for bare metal services and create the appropriate type of block storage.

[0062] 8.1) Mount block storage;

[0063] 8.2) Unmount.

[0064] In this invention, a unified bare metal resource pool is deployed and constructed within each POD according to the network planning, and a bare metal remote management module is deployed within the POD to be responsible for the unified management and scheduling of the bare metal resources of the POD.

[0065] This invention's bare metal block storage service requires integration with OpenStack services to enable unified management of virtual machines and bare metal instance block storage services via a remote management module. It uses the same interface as existing virtual machines using block storage services, eliminating the need for secondary adaptation by the cloud management platform. The specific implementation process is shown below, consisting of three parts:

[0066] 1. Data Registration: Collect bare metal server HBA card information and register ironicvolume-connector in batches to support subsequent mounting of FC block storage;

[0067] II. Remote Operations: Enhance nova-api, nova-compute, and ironic-driver to enable existing volume service interfaces to support volume operations for bare metal instances;

[0068] III. Volume Service Module: The volume service client is deployed on the control node. The volume service agent is installed in the bare metal image. Through nova-api, the volume service client on the control node is called. The client calls the volume service agent inside the target bare metal instance via RPC to complete the volume operation and return a response.
