Request processing method of distributed storage system

Abstract

The invention discloses a request processing method of a distributed storage system and belongs to the technical field of information storage. The method comprises, in a multi-copy distributed storage system with main new energy source power supply and supplementing mains power supply, dynamically opening and closing data nodes to enable the entire system to dynamically matched with the power supply of new energy sources; adding SSD (solid state disk) nodes, which take SSDs as storage mediums, as system buffers, dividing non-deferrable timely requests for closing the data nodes into two phases including a low-energy-consumption timely online response phase and a high-energy-consumption background offline storage phase, guaranteeing performance requirements during the online phase, and making full use of the new energy sources during the offline phase; meanwhile, for also taking system reliable into consideration, laying off the free space in the data nodes as virtual SSDs for backing up dirty data in the data nodes. Compared with traditional data node opening and closing strategies based on load change, the request processing method of the distributed storage system can greatly improve the utilization rate of the new energy sources under the premise of not affecting request response.

Description

technical field [0001] The invention belongs to the technical field of information storage, and more specifically relates to a method for processing requests of a distributed storage system. Background technique [0002] With the rapid development of the information age, all kinds of information (text, sound and images, etc.) have increased dramatically at an incredible speed. The rapid growth of data has the most direct impact on the data center is the continuous growth of the number of servers, and the energy consumption of large data centers is very alarming. Different from traditional high-carbon electricity, new energy often has the characteristics of unstable intervals and dynamic changes. How to maximize the use of new energy is also a major problem faced by data centers. The most important problem in the study of maximizing the utilization of new energy is how to dynamically match the unstable and dynamically changing new energy with the load of the system. The solu...
