Problems solved by technology

However, in the prior art, when the redundant data is distributed on different machines, a random method is adopted, and different machines are not selected, resulting in that the machines with the same data distribution may be fault-prone machines, thus causing difficulties in data maintenance and Increased risk of data loss

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0016] See attached figure 1 , is a multi-node system to which the present invention is applied, and the system includes a plurality of computing nodes.

[0017] See attached figure 2 , a redundant data processing method in a multi-node system, the method comprises the steps of:

[0018] (1) Calculate the m nodes i in the multi-node system according to the storage capacity, operating load and failure frequency according to the following formula (a) to determine the storage risk value R of each node i :

[0019] R i = S i ×P i +1 / F i ×Q i +G i × T i (a);

[0020] where S i Indicates the storage capacity of node i, P i Indicates the weight corresponding to the storage capacity, F ...

Abstract

The invention relates to a redundant data processing method in a multi-node system, a node with a relatively high storage risk value and a node with a relatively low storage risk value are taken as one storage group, thus, an average storage risk value in each group is relatively balanced, a situation where a plurality of nodes for distribution of the redundant data are all frequently failed nodesis avoided, and the redundant data are distributed to the group with balanced storage risk, so data maintenance is facilitated and the risk of data loss is reduced.

Description

【Technical field】 [0001] The invention belongs to the field of data storage, in particular to a multi-node redundant data processing method. 【Background technique】 [0002] Under normal circumstances, the maximum throughput provided by a machine can only reach 200MBps. If the usual machine mirroring method is used, that is, the data on several machines is completely consistent, it will take more than 20 hours to repair 12TB of data. Considering Under normal service pressure, the repair time will reach dozens of hours. [0003] In the prior art, the data storage and processing method in multi-node is proposed, the data is divided into multiple libraries, and several redundant copies are copied. Different redundant distributions of the same library are stored in different locations of different machines, which improves the repair speed. However, in the prior art, when the redundant data is distributed on different machines, a random method is adopted, and different machines a...
