Application scenarios
In the actual application scenario, we focus on the practical application of "optomagnetic fusion storage system" in smart city and smart park. Yihua-recording optical and magnetic fusion storage system is a data storage planning concept based on the characteristics of big data in the current industry, and also an architectural design scheme of the data center storage system.
From the industrial statistical analysis results, the current unstructured data volume has accounted for more than half of the total data. Especially in large cloud storage data centers, unstructured data can take up more than 80% of the storage space. However, most of the data has the property of life cycle. The access frequency of historical data is reduced to cold data, but the accumulated space is gradually increased.
Relying on the latest blue-ray storage technology and taking large enterprise-class blu-ray disc library as the cold storage target, yihua-lu optical and magnetic fusion storage concept is closely connected with the disk main storage system to form a storage system that can be planned and extended with timeliness, economy and continuous service capacity.
(I) technical description of optical magnetic fusion integrated storage system:
1. Optical magnetic mixing, data automatic hierarchical storage technology, combines the advantages of magnetic storage and optical storage, classifies data and reduces the cost of storage, and the data will be automatically migrated between disk and blu-ray disc library.
2. According to the optimization algorithm for the perception of specific file type content, the uncommon data content is stored in the optical disc library, which will not be accessed in most application scenarios.
3. Data encryption technology supports the encryption of data uploaded by users.
4. De-duplication and compression technology, using online compression and file-based repeated data removal algorithm, supports the compression of data uploaded by users to save space for cold storage.
5. Integrated optical and magnetic storage and supporting application platforms provide cloud services to users in the cloud storage service mode.
6. The optical magnetic fusion storage system and front-end application system are connected by NAS or REST programming API, which can be flexibly selected according to the requirements of system integration. Object storage is adopted at the bottom of the storage system to support distributed storage architecture and parallel processing, and the storage nodes can be extended as required to realize massive expansion of storage space.
(ii) application advantages of optical magnetic fusion storage architecture:
1. For massive unstructured cold data storage, the application of blu-ray disc library equipment will greatly reduce the cost of storage equipment and operation and maintenance costs, improve the safety and reliability of data storage, and achieve significant economic and social benefits:
2. Cold data is not frequently accessed. If it is stored on the disk for a long time, the high performance of the disk will not be given full play, and the disk usage efficiency and ROI will be reduced.
3. Massive cold data storage requires massive storage space, and the cost of the disk storage device with large amount of data is higher than that of CD storage.
4, massive amounts of disk storage devices long running costs and cooling air conditioning power consumption cost, much higher than the cost of the power of the blu-ray disc library and cooling costs, blu-ray disc library to read and write when consumed less than 300 w, when standby power consumption is less than 10 w (reference value: 1 PB data storage for 30 years, blu-ray disc library consumed only about 0.3% of the disk array).
5. The disk life is generally 3-5 years, and the tape life is 5-10 years. The long-term storage of data requires constant replacement of the disk or tape, which increases the maintenance cost. Magnetic tape also has demagnetization, adhesion, wear and other problems, while optical disc storage life up to 100 years, long-term storage without maintenance, reduce maintenance costs.
6. The optical disc media is an unchangeable storage medium, which ensures the authenticity of data writing and complies with the requirements of industry regulations on the authenticity of data archiving and storage, and has legal benefits.
7. The low energy consumption of the optical disc storage equipment is in line with the national requirements of low-carbon, environmental protection and green data center construction.
8. Massive data storage is the basic function of the big data center. The optical magnetic hierarchical storage structure is established to enable the storage system to have unlimited expansion capacity and ensure the continuous and stable operation of the big data center.
9. The reliability and security of blu-ray storage ensure the security of user data and improve the service capacity and level of the data center.
Application examples
Classic example: China hualujin south data lake industrial park
At present, the real intelligent parks in China are not very perfect, but a number of pioneers have emerged. For example, the jinnan dathu industrial park built by China huadu in tianjin is a practical intelligent park and a classic case of intelligent parks. It is called "future science park", also known as "data lake industrial park". We think this is a typical "intelligent park". The park is located in the balitai industrial park, jinnan district, tianjin city, with a total land area of 206,6596.2 square meters, a total construction area of 357,616.6 square meters, and a total investment of 1.67 billion yuan.

The company has positioned the industrial park as the main business type with big data + Internet. Through the construction of smart cities, smart parks and data lakes, the big data industry will be built to form a big data ecosystem based on Beijing, tianjin and hebei. TODA tianjin open data innovation application contest to create the name card of tianjin and promote the development of big data industry. Become China's leading intelligent society, intelligent park service solution provider and operator.
Xi stressed that the 19th CPC national congress mapped out the grand blueprint of finishing building a moderately prosperous society in all respects, embarking on a new journey of building a modern socialist country in all respects and realizing the great rejuvenation of the Chinese nation, and made strategic plans for building a strong cyber country, digital China and a smart society. To speed up the development of digital China, we need to adapt to the new historical orientation of China's development, fully implement the new development concept, cultivate new driving forces through informatization, promote new development with new driving forces, and create new glory with new development.
It is under this background that yi huayu enters the construction period of smart city, smart park and data lake, and in the future it will be accelerated to land in the whole country. The framework system of "city data lake" proposed by the company caters to the development trend of national big data industry and the development requirement of "digital China" proposed by the 19th CPC national congress. In 2016, the market size of China's big data industry was 248.5 billion yuan, and the China commercial industry research institute predicted that the market size would reach nearly 600 billion yuan in 2018. Therefore, the company's big data and smart park with data lake as the core will usher in the golden period of industrial development. At present, the company has cooperated with more than 50 partners to build the data lake ecology, forming the model barrier. With the completion of jiangsu taizhou and xuzhou projects, the company has entered the construction period of data lake, and the strategic concept and application are in the forefront of the industry. In 2017, the company successfully signed framework cooperation agreements with nine regions, and continued to push forward more than 20 regions, laying the foundation for the acceleration of data lake business in the country.
Coordinated development of smart city, smart park and data lake. The "1+3" strategy is to combine the company's traditional smart city, smart park industry and data lake.
