AI Technical Summary

Technical Problem

The existing distributed storage systems cannot accurately divide hot and cold data, resulting in high energy consumption and frequent switching of energy saving levels lead to increased energy loss.

Method used

By introducing a plurality of first storage nodes and second storage nodes into the data storage system, the energy consumption of the first storage node is higher than that of the second storage node. The data aggregation and energy saving level control method are used to aggregate the additional written data into the read replica set, and the read replica set and the read and write replica set are used to replace the traditional hot and cold data distribution method to reduce high-frequency energy saving level switching.

Benefits of technology

It effectively reduces energy losses caused by energy saving level switching and improves the energy efficiency and responsiveness of the data storage system.

Abstract

The invention provides a data storage method and device, a management node, a medium and a data storage system, the data storage method and device are applied to the management node in the data storage system, the data storage system further comprises a plurality of first storage nodes and a plurality of second storage nodes, and the energy consumption of the first storage nodes is higher than that of the second storage nodes. The plurality of first storage nodes are used for responding to a data reading request sent by a terminal device, the method comprises the following steps: receiving a write-in request sent by the terminal device, the write-in request carrying first data; determining a first logic storage unit corresponding to the first data according to the type of the first data; wherein data stored in the logic storage unit can be mapped to each storage node; and additionally writing the first data into the first logic storage unit, so that the first logic storage unit additionally writes the first data into the first storage position of each storage node. According to the method provided by the invention, the energy loss caused by energy-saving grade switching is effectively reduced.
