Build a national data element circulation data infrastructure for the large market of national unified data elements

4. Rapid improvement, broad prospects for development and application

First, investment has increased rapidly and maintained a rapid growth trend. It is estimated that the growth rate of China's saving investment from 2017 to 2019 is as high as 45.4%, far exceeding the growth rate of saving investment in developed countries such as the United Kingdom and the United States of 18.5% and 3%. Second, the adequacy of China's storage power has gradually increased, reaching 8.9%, indicating that the proportion of data that can be stored in the data set that is created, collected or copied in China has reached 8.9%, which can better support the high-quality development of the digital economy. Third, the rapid development of full flash storage. From the perspective of market size, IDC data shows that in 2021, China's full flash storage market share accounted for 19%, and maintained a rapid growth level of 26%.

03 Development Path

According to the new data infrastructure construction idea of "focusing on the point, bringing the line with the point, promoting the surface with the line", the data infrastructure construction of various industries, fields and regions will be promoted in stages.

1. The first stage: strong capacity to promote the transformation and upgrading of key node all-flash data centers

Combined with the specific application scenarios, starting from the construction of a single data center, transformation and upgrading are carried out in accordance with the construction requirements of all-flash data centers, and the proportion of all-flash in new data infrastructure is increased, and the overall storage level of China's data infrastructure equipment is effectively improved.

The first is to mark the five characteristics of all-flash data centers and promote the upgrading of traditional data centers. Medium flash storage (also known as "silicon advance magnetic retreat"), the use of flash hard disk (SSD) to gradually replace mechanical hard disk (HDD), "fourteen five" period should achieve flash memory ratio of more than 50%; Network IP, promote all-flash data center high-performance Ethernet storage network, gradually realize all-IP network, increase bandwidth, improve protocol conversion efficiency, improve overall performance by more than 35%, save operation and maintenance costs; Data protection is multidimensional, improving data disaster recovery capability for core data and important data in terms of data disaster recovery speed, recovery speed, copy usage frequency, disaster recovery data scope, disaster recovery level, and retention time. Storage and computing decoupling, that is, using the storage and computing decoupling architecture, through application transformation, to achieve data resource sharing of multiple computing facilities and efficient utilization of storage facilities, avoid large-scale data redundancy to occupy storage space, and improve comprehensive data management capabilities; Intelligent management, the use of AI, automation and other technologies to achieve the autonomous operation and maintenance of data center equipment, reducing operation and maintenance costs. Reduce data center energy consumption through unified resource scheduling, efficient provisioning and recycling.

In accordance with the above five standards, promote key industries such as government departments at all levels, financial industry, health care, manufacturing industry, and communications industry to take the lead in realizing the advanced deployment of full flash storage technology, while speeding up the process of flash storage of traditional mechanical hard disk, promoting the transformation and upgrading of the stock "scattered small and old" data centers in different batches, and creating all-flash data center model projects.

The second is to take the construction of national data infrastructure hub nodes as an opportunity to improve the coverage of all-flash data centers. Optimize the layout of data infrastructure construction, take the national integrated big data center and the construction of the "East data and West calculation" project as an opportunity to increase the proportion of data infrastructure construction with full flash data centers as nodes, and the flash memory ratio of new data centers should exceed 70%; Improve the memory level, promote the key node data infrastructure memory level to single cluster PB level, storage performance to μs level delay; Promote all-IP storage network, actively promote high-performance Ethernet storage network, streamline the operating system protocol stack, achieve faster throughput bandwidth and lower latency, intelligent operation and maintenance management; Establish and improve the disaster recovery system, expand disaster recovery coverage, upgrade data disaster recovery level, and realize local active-active/active-passive disaster recovery, remote 3DC, and cloud data protection. Promote green "zero carbon" development, use flash storage media, storage and computing decoupling data sharing and intelligent management and other technologies and means to gradually promote the green and energy-saving development of data centers with the advantages of high quality and high utilization of storage resources; Establish and improve the standard and specification system for data infrastructure, accelerate the formulation and promotion of common and key technical standards for data infrastructure, and improve standards for data sharing, network security, testing and evaluation related to data infrastructure.
