Rapid development in technology today, data centers are also undergoing change, with the advent of new technologies and the development of ideas, data centers greater emphasis on efficient, reliable and flexible. Driven by emerging technologies artificial intelligence, cloud computing, networking and other data generated showing explosive growth. Such as Internet companies, financial institutions, healthcare, etc., so the rise of a data center construction boom.
With the addition of various sectors and enterprises in recent years, the scale of our data center gradually expanded, according to the COG Advisory (China IDC Circle) "issued 2018--2019 China's IDC industry research report" shows that in 2018, IDC China business the total market reached 122.8 billion yuan, an increase of 29.8% is expected by 2021, IDC China business market will be more than 270 billion yuan, the annual growth rate remained at about 30%.
China Mobile, together with China Telecom, China Unicom, China ICT Academy and Intel co-sponsored server open project, in November 2017 project in ODCC (Open Data Center Committee) server Working Group, the goal is to form a carrier industry depth for telecom application customization open standards, standardized server technology solutions and prototypes.
5G Kwai Fong era of cloud computing will push low-cost, low-power technology development of very large data centers, the demand for servers also produce changes in temperature, dust, corrosion resistance, electromagnetic compatibility, earthquake, also made enhancements. Data center servers must have a more balanced all-around mode, and distributed cloud storage servers in various applications have shown a more comprehensive hardware devices.
Six advantages of distributed storage
- High performance
having a high-performance distributed cloud storage to efficiently manage read, write cache, the cache with significant changes to the overall performance of the memory, the cache data is written first, then synchronize off disc at the appropriate time. - Hierarchical storage
distributed storage memory allows high-speed and low-speed storage deployed separately, or mixed in any proportions cloth, hierarchical storage may play to the best advantage. - Consistency of multiple copies
before storing the data, the data is distributed storage fragmentation, using a copy of the writing, reading of multiple copies consistent technology to ensure the total number of copies is fixed. - Backup and disaster recovery
in distributed storage disaster recovery, an important means is more time snapshot technology, enabling users to achieve the production system can save each version of the data at certain time intervals. - Elastic expansion
due to reasonable distributed architecture, distributed storage can be elastically extended and the estimated calculation, storage capacity and performance. - Standardization storage
distributed storage precedence industry standard interface (SMI-S or OpenStack Cinder) for storing an access for centralized management of storage resources, procurement and storage reduces management costs.
Distributed storage is not only to improve the reliability, availability, access and efficiency of the system, but also easy to expand, the instability common hardware introduced to a minimum. 5G era of distributed cloud storage server will come out on top!
