NFS distributed file service system and construction method

Abstract

The invention relates to an NFS distributed file service system and a construction method. An existing NFS single-node deployment mode is improved. A multi-level NFS service level is designed and introduced; the front NFS file service gateway is respectively connected with each relay NFS file service gateway; then, the relay NFS file service gateway is respectively butted with each NFS file service node; finally, each NFS file service node is in butt joint with the storage equipment; according to the method, the virtual file directory corresponding to the NFS service of each level in sequenceis obtained on the basis of the storage path of each file in the storage equipment, and finally the virtual file directory presented on the user side is formed, so that the files in the storage equipment are accessed, the data access capability is effectively improved, and the data access working efficiency is ensured.

Description

Technical field [0001] The invention relates to an NFS distributed file service system and a construction method, belonging to the technical field of distributed file systems. Background technique [0002] At present, cloud computing is a hot topic of enterprise cloud construction. The advantages of cloud computing can be summarized into two categories, operability and economy. Cloud computing provides fast self-service. Through API, resource deployment and removal tasks can be automated, which improves agility and delivery speed, and increases the flexibility of enterprise information systems. As the underlying service of cloud computing, distributed file storage provides important data support for cloud computing. Distributed file storage can effectively store and manage the massive amounts of data generated during enterprise production management. At the same time, using the advantages of cloud computing, the distributed file system can easily achieve elastic scaling. [0003...

AI Technical Summary

Problems solved by technology

NFS has formulated a protocol specification for network file access and transmission, which effectively solves the problem of network-based file access. However, traditional NFS or NAS (network-attached storage devices) are deployed on a single node, and the capacity of a single-node physical hard disk cannot meet the growing needs of enterprises. Massive data access requirements, that is, general NFS file servers or NAS (network attached storage devices) are mounted real physical hard disks, which provide access capabilities such as file creation and modification for physical hard disks, and file directories and files are created and stored in corresponding file directory

However, with the increase of the file directory tree, it is difficult to carry out unified management of the file directory, and the massive directory tree structure will also reduce the efficiency of physical hard disk usage
