Problems solved by technology

[0015] (2) FC-SAN, iSCSI and other block storage technologies implement block data reading and writing between SCSI initiators and targets through SCSI-3 commands, which are suitable for processing a large number of block data I / O read and write requests. The processing of frequent small data I / O read and write requests in the education cloud has a bottleneck in response performance
[0017] (4) Object storage technology cannot provide good response performance for frequent small data I / O read and write requests, and large-scale block data I / O read and write requests
[0018] To sum up, there is no effective solution for how to ensure high response performance when processing I / O requests in educational cloud applications

Embodiment Construction

[0073] In the process of implementing the present invention, the inventor found that there are three typical types of I / O requests on the education cloud platform, such as image 3 As shown, including: 1) large data block I / O write request, corresponding to electronic courseware processing and other services; 2) large data block I / O write request, corresponding to online reading, e-books and other services; 3) small data I / O Continuous read and write requests, the corresponding services include: Internet browsing, log processing.

[0074] Moreover, the inventors further found that, since the block storage device has the ability to provide high-speed I / O, it can be used to handle large data block I / O continuous read and write requests and small data block I / O continuous read and write requests in the education cloud; The distributed file system has high scalability and multi-copy capabilities, which ensures data reliability and is suitable for processing large data block I / O ra...

Abstract

The invention discloses a cloud virtual file system and an I / O (input / output) request processing method thereof. The I / O request processing method of the cloud virtual file system includes: using the cloud virtual file system to receive an I / O request sent by a cloud application system; confirming the type of the I / O request according to parameters carried by the I / O request and a disk reading or writing position requested in the I / O request; invoking a distributed file system to respond to the I / O request or invoking a local file system based on a block device to respond to the I / O request according to the confirmed type of the I / O request.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a cloud virtual file system system and an input / output request processing method thereof. Background technique [0002] The advent of the Internet era has brought new industrial opportunities or opportunities for industrial upgrading and transformation to various industries, such as TV, business, newspapers, etc., which have evolved into Internet TV, e-commerce platforms, portals, etc. based on the Internet platform. . Cloud computing is a more advanced technology in the Internet era. It virtualizes various information (IT, InformaTion) resources and storage resources, and provides software as a service (SaaS, Software-as-a-Service), platform as a service (PaaS, Platform-as-a-Service) and other service models, cloud computing provides new ideas and models for more industrial development. [0003] Education cloud is a cloud computing platform for the education field in the Interne...
