Today, with the rapid development of science and technology, the data center is also undergoing changes. With the emergence and development of new technology concepts, data centers put more emphasis on efficiency, reliability and flexibility. Driven by artificial intelligence, cloud computing, Internet of things and other emerging technologies, the resulting data shows an explosive growth trend. Such as Internet enterprises, financial institutions, medical industry and so on, thus springing up an upsurge of data center construction.

With the entry of various industries and enterprises, the scale of China's data centers has gradually expanded in recent years. According to the Research report on the Development of China's IDC Industry from 2018 to 2019 released by Science and Technology Consulting (China IDC Circle), the total size of China's IDC service market reached 122.8 billion yuan in 2018, an increase of 29.8% over the same period last year. It is estimated that by 2021, the size of China's IDC service market will exceed 270 billion yuan, with an annual growth rate of about 30%.

The server opening project launched by China Mobile in conjunction with China Telecom, China Unicom, China Communications Institute and Intel was established in the ODCC (Open data Center Committee) Server working Group in November 2017. the goal is to form deeply customized, open standards and unified server technology solutions and prototype products for telecom applications in the operator industry.

In the 5G era, Kuifang Cloud Computing will promote the development of low-cost, low-power technology super-large data center, and the demand for servers will also change, and it will also be enhanced in high temperature resistance, dustproof, corrosion resistance, electromagnetic compatibility, earthquake resistance and so on. The data center server must have a more balanced and versatile mode, and the distributed cloud storage server is a more comprehensive hardware device in each application.

Six advantages of distributed storage

High performance

A high-performance distributed cloud storage can efficiently manage read and write caches, cooperate with high-speed storage to significantly change the overall storage performance, first write data to high-speed storage, and then synchronously set the disk at an appropriate time. Support for hierarchical storage

Distributed storage allows high-speed storage and low-speed storage to be deployed separately, or mixed in any proportion, and the advantages of hierarchical storage can be brought into full play. Consistency of multiple copies

Before storing the data, distributed storage divides the data into pieces, using the consistency technology of writing one copy and reading multiple copies, so as to ensure that the total number of copies is fixed. Disaster recovery and backup

In the disaster recovery of distributed storage, an important means is the multi-point-in-time snapshot technology, which enables the user production system to save each version of data at a certain time interval. Elastic expansion

Thanks to a reasonable distributed architecture, distributed storage can be predicted and flexibly scale computing, storage capacity, and performance. Storage system standardization

Distributed storage preferentially uses industry-standard interfaces (SMI-S or OpenStack Cinder) for storage access to achieve centralized management of storage resources and reduce storage procurement and management costs.

Distributed storage not only improves the reliability, availability and access efficiency of the system, but also is easy to expand to minimize the unstable factors introduced by general hardware. Distributed cloud storage servers will be at the top in the 5G era!
