Embodiment 1

[0039] Such as figure 1 As shown, a low-energy cluster storage replication device based on data behavior includes:

[0040] The metadata server is mainly responsible for providing virtual services to customers. The request sent by the customer will first arrive at the metadata server, and then the metadata server will forward the request to an effective scheduling algorithm according to the specific load situation of the storage server. A suitable storage server is used for processing. When the storage server is processed, it does not need to go through the metadata server and returns the result directly to the client. In this way, the metadata server acts as a load balancer on the cluster storage system. Roles;

[0041] Storage servers are divided into hot node sets and cold node sets, among which:

[0042] Hot node collection, it stores small data volume and frequently accessed hot data by customers. It is always working to ensure the quality of service of the storage system. The...

Abstract

The invention discloses a data behavior based low-energy consumption cluster storage replication device and method. The data behavior based low-energy consumption cluster storage replication device comprises a metadata server and a storage server. The storage server is composed of a hot node set and a cold node set. The data behavior based low-energy consumption cluster storage replication method includes that the hot node set is in a normally open state to store hot spot data frequently accessed by clients and provides QoS (quality of service) guarantee for a storage system; the cold node set stores cold spot data containing large amount of data and seldom accessed by the clients, automatically transfers into a dormant state in the absence of requests, and immediately switches back to a working state to process requests once arriving. Since data access behaviors of the clients are subject to a 80/20 rule, that is, 80% of the requests concentrate on 20% of the hot spot data, while only 20% of the requests access to 80% of the cold spot data. By the method, energy consumption of a system can be greatly reduced on condition that the quality of service of storage cluster system performance is guaranteed.

Description

Technical field [0001] The invention relates to the field of data storage and replication research, in particular to a low-energy-consumption cluster storage replication device and method based on data behavior. Background technique [0002] Due to the application requirements of computer technology, data is increasing explosively. Because cluster storage based on commercial components has high scalability, it is becoming a next-generation storage system architecture for big data. However, with the continuous expansion of system scale, hardware failure in the system has become a normal state. The main reasons for these hardware failures are hardware overheating, power failure, disk damage, network wiring and maintenance, etc. In addition, due to natural disasters, hacker attacks, etc., the system will fail. Various failures will reduce the availability of the storage system to the 95% to 99.6% range. This is unacceptable for the majority of users. Data replication technology ...
