Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0033] The embodiment of the present invention is aimed at the cluster NAS environment, when multiple cluster NAS nodes provide users with the same shared file system, the client distributes the access requests to different cluster nodes according to the policy through the load balancing agent, so as to realize the average load distribution , so as to avoid the situation that some nodes are overloaded and other nodes are too idle.

[0034] When multiple clients need to access the NFS service provided by the clustered NAS, a load balancing agent is installed for each client. The load balancing agent of each client is responsible for processing the local NFS requests without affecting other clients.

[0035] Such ...

Abstract

The invention relates to the technical field of cluster network attached storage and discloses a network file system access method and device. The method comprises the following steps: receiving network file system input/output request; if the mount point corresponding to the request is in cluster state, distributing the IP addresses of the remote server providing the network file system according to the request; and utilizing the distributed IP addresses to perform network file system access. By using the network file system access method, device and system of the invention, a plurality of different cluster NAS nodes in the cluster can be selected for NFS shared access so as to realize the load balance among the cluster NAS nodes and the maximization of the resource utilization.

Description

technical field [0001] The present invention relates to clustered NAS (Network Attachment Storage, network attached storage) technology, in particular to a network file system access method, device and system. Background technique [0002] All information can be roughly divided into two categories: one type of information can be represented by data or a unified structure, which is called structured data, such as numbers and symbols; the other type of information cannot be represented by numbers or a unified structure at all, such as Text, images, sounds, and even web pages are called unstructured data. [0003] At present, with the rapid development of applications such as Web and video, the demand for unstructured data storage is becoming more and more intense, and NAS technology with large capacity and high performance is widely favored. Among them, the cluster NAS technology has been rapidly developed due to its high scalability and high performance. The clustered NAS s...
