Problems solved by technology

[0006] In the above methods, there are technical defects: after using raid5, when a large-capacity hard disk fails and the faulty disk is replaced, the rebuilding time will be as long as several days. If the hard disk failure continues during the rebuilding period, the entire raid5 data will be lost, causing a failure long recovery period

Embodiment Construction

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] see figure 1 , this embodiment discloses a method for storing CDN edge node files, which specifically includes the following steps:

[0074] S101: Obtain a raid card supporting the Nonraid mode, and connect the hard disk group to the edge node server through the raid card;

[0075] The Nonraid mode does not use raid mode, each hard disk is a logical disk, and there is no data block striping.

[0076] A raid card that supports the Nonraid mode is selec...

Abstract

The invention provides a storage method and device for CDN edge node files. The storage method includes the steps that a raid card supporting a Nonraid mode is selected, and hard-disk names of all hard disks are obtained; a hard-disk pack is connected with an edge node server through the raid card; the hard-disk pack is initialized; according to the hard-disk names of all the hard disks, Hash values of file names of all to-be-stored files and the preset rule, all the to-be-stored files are stored to the corresponding hard disks respectively. All the hard disks are in the independent operation state, it is avoided that in the prior art, a hard disk is required to serve as a redundancy disk when a raid5 is established, and the maximum capacity of the edge node server is increased; even if two or above fault disks appear, it is avoided that the whole server cannot be used, and when the fault disks are replaced, data of the fault disks of the edge node server only needs to be newly synchronized, fault time is greatly shortened, and the stability of a system is improved.

Description

technical field [0001] The present invention relates to the technical field of file storage, and more specifically, to a CDN edge node file storage method and device. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. The basic idea is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. By placing node servers all over the network to form a layer of intelligent virtual network based on the existing Internet, the CDN system can real-time base on the network traffic, the connection of each node, the load status, the distance to the user and the response time, etc. The comprehensive information redirects the user's request to the service node closest to the user. Its purpose is to enable users to obtain the required content nearby, solve the congestion situation of the Intern...
