Block storage access method based on object storage protocol

Abstract

The invention discloses a block storage access method based on an object storage protocol. The block storage access method comprises the following steps: firstly, sending a request for uploading, downloading and deleting an object file through a client of an object gateway service, wherein when the uploaded object file is a mirror image file, the file attribute of the mirror image file is set to be 'X-Meta-Bingo-MyImage'; then, enabling the object storage gateway to identify parameters of the object file, and the parameters comprising file attributes; if the file attribute conforms to 'X-Meta-Bingo-MyImage', calling the block storage interface according to the request, writing the mirror image file into the block storage, downloading the mirror image file, deleting the mirror image file, and then returning to the client; and otherwise, directly executing the request of writing, downloading and deleting the object file in the object storage pool. The problem of data isolation between the storage pools of the distributed storage system is mainly solved, so that a user can conveniently and directly access the block storage in the block storage pool through an object storage protocol, the user does not need to depend on a transfer module or an additional transfer module machine, the waste of resources is reduced, the key problem that a user uses a customized virtual machine in the field of cloud computing is solved, and the invention can be effectively popularized.

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
