A Block Storage Pool Access Method Based on Object Storage Protocol

Abstract

The invention discloses a method for accessing block storage based on an object storage protocol, which includes first sending a request including uploading, downloading, and deleting an object file through a client served by an object storage gateway; wherein, when the object file is uploaded as a mirror image file, Set the file attribute of the image file shown as: "X-Meta-Bingo-MyImage"; then, the object storage gateway identifies the parameters of the object file, and the parameters include file attributes; if the file attributes conform to "X-Meta ‑Bingo‑MyImage”, call the block storage interface according to the request, the block storage writes the image file, downloads the image file, deletes the image file, and then returns to the client; otherwise , directly execute the request in the object storage pool: write, download, delete the object file. The present invention mainly solves the problem of data isolation between the storage pools of the distributed storage system, so that users can directly access the block storage in the block storage pool through the object storage protocol, and the user does not need to rely on the transfer module, and does not need an additional transfer module. Machines can reduce the waste of resources and solve the key problems of users in the field of cloud computing using customized virtual machines, which can be effectively promoted.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a block storage access method based on an object storage protocol. Background technique [0002] The virtual machine is a major technology in the field of cloud computing, and the virtual disk of the virtual machine needs to use a block device. Ceph is a distributed storage system that is widely used in the field of cloud computing. It can provide object storage gateway services and block storage services. Among them, object storage gateways can support the widely used S3 protocol, and block storage services can be used by virtual machines to provide virtual disks. . Mirroring is the concept of the virtual disk of a virtual machine. By customizing the mirroring, users can easily run private business systems in the virtual machine, such as running web servers, databases, and security software. If users want to create their own designed virtual machines on the cloud platform, they ...

Problems solved by technology

[0006] However, the registration and download of the image is very troublesome. It needs to be operated many times in the middle, and it needs to be transmitted multiple times through the network. Usually the size of the image is more than GB, which takes a long time. In the case of poor network, the time-consuming problem is even more serious; and it only depends on transit The module is easy to cause single point of failure, and the machine network bandwidth, storage capacity and disk I / O performance of the limited transit module increase the difficulty and cost of operation and maintenance; the design of the transit module needs to consider concurrency performance and the distribution of large traffic Consider ensuring that the previous tasks can continue to execute correctly after the service is restarted, which increases the difficulty of development
