What are the storage methods of data?

Distributed storage is a data storage technology, which uses the disk space on every machine in the enterprise through the network. These scattered storage resources constitute a virtual storage device, and the data is distributed and stored in every corner of the enterprise.

Distributed storage system, which can distribute data on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage server has become the bottleneck of system performance and the focus of reliability and security, which can not meet the needs of large-scale storage applications. Distributed network storage system adopts scalable architecture, uses multiple storage servers to share storage load, and uses location servers to locate and store information, which not only improves the reliability, availability and access efficiency of the system, but also is easy to expand.

Advantages of distributed storage

Scalability: The distributed storage system can be extended to hundreds or even thousands of such clusters, and the overall performance of the system can be linearly improved.

Low cost: The automatic fault tolerance and automatic load balancing of distributed storage systems allow the construction of distributed storage systems on low-cost servers. In addition, linear scalability can also increase and reduce the cost of servers and realize the automatic operation and maintenance of distributed storage systems.

High performance: Whether it is a single server or a distributed storage cluster, a distributed storage system needs high performance.

Ease of use: Distributed storage systems need to provide a convenient and easy-to-use interface. In addition, they need complete monitoring and operation tools and can be easily integrated with other systems.

Sugiyama distributed unified storage USP

Using distributed technology, the storage media such as HDD and SSD of standard x86 servers are abstracted into resource pools, which provide standard access interfaces for blocks, files and objects for upper applications.

At the same time, it provides a clear and intuitive unified management interface, reduces deployment and operation and maintenance costs, and meets the needs of large-scale storage resource pool construction with high performance, high reliability and high scalability.
