 What kind of distributed storage is needed in 5g Era


Today, the 5g industry chain, including system equipment, smart phones, chip modules, testing and measurement, has entered a mature stage. Under the guidance of policies and operators, various innovative applications for consumers and industries are springing up in an endless stream. According to incomplete statistics, China has more than 19 industries and more than 4000 organizations carrying out 5g cross industry innovation, involving the mainstream scenes of transportation, medical, manufacturing, energy, new media and other industries.

With the advent of 5g era, with the synergy of cloud, AI, big data and other new technologies, the data flowing on the network will grow geometrically. According to Huawei [email protected] It is predicted that the new data volume will reach 180zb by 2025, 18 times of that in 2018; similar figures have also appeared in many third-party reports.

On the one hand, this is a good thing. Data has become one of the power sources of human social progress. Both the development of digital economy and the digital transformation of various industries are based on data value mining. In April this year, the central government issued the opinions on building a more perfect market-oriented allocation system and mechanism of factors, bringing data into the scope of production factors for the first time. On the other hand, to make use of data, we must first survive. However, according to statistics, less than 2% of the current data are saved, and most of them have to be abandoned; from mobile phone, wearable devices to smart home, smart community, to intelligent medical treatment, intelligent factory, and autopilot. The diversity of scenarios drives the diversity of data. In the future, with more fierce digital floods, the situation will be more severe.

It can be seen that storage has become the demand of 5g era, and storage devices need to be upgraded to provide stronger carrying capacity and keep up with the pace of data growth.

What kind of distributed storage do operators need?

As the builders and operators of 5g network, telecom operators are bound to bear the brunt of this storage revolution; at the same time, operators are the leaders of the value chain, and their choices often affect many people.

Today, distributed storage is becoming a trend. IDC predicts that by 2023, about 40% of storage systems will be based on distributed architecture. But at the same time, the debate between soft hard decoupling or soft hard integration has become a continuous focus. The former once became politically correct, and with the passage of time, the latter began to gain the upper hand.

For the support requirements of 5g three typical application scenarios, distributed storage must achieve high performance, large capacity, low delay, and also consider the reliability, cost and other aspects. This can not be achieved only by pure software. It is just a castle in the air to talk about software definition without hardware. In fact, even Internet companies, pioneers of distributed storage and software hardware decoupling, have begun to embrace the integration of software and hardware through self-study or merger and acquisition, because they find that even with outstanding software capabilities, they need high-performance hardware to match.

As a telecom operator with the largest network scale, the largest number of users and the highest brand value in the world, China Mobiles choice is very representative. In recent years, the centralized purchase of distributed storage has gradually tended to integrate software and hardware. At the end of last year, the results of the annual centralized purchase of distributed block storage at the headquarters of the group caused a ripple in the industry. The overall scale of centralized purchase exceeded 200 million yuan, and the winning bidders were manufacturers with strong hardware capabilities such as Inspur and Huawei.

The announcement of the results of centralized acquisition of distributed block storage in the second phase of network cloud resource pool project in 2019 means that China Mobile has gone further and firmly on the road of integrating software and hardware. The purpose of this centralized procurement is to support the construction of nfv full cloud network in the 5g era of China Mobile, carrying core business such as 5gc, IMS, EPC, etc., and the final purchase amount is nearly 600 million yuan (excluding tax). The winning bidder is Huawei, China Mobile integration and Inspur, which is totally inclined to the integration of software and hardware. In the announcement of the successful candidates for centralized acquisition of distributed block storage from 2020 to 2021, Huawei, which has always adhered to the integrated software and hardware model and recently released the oceanstor storage Pacific series of special hardware, once again gained more than half of the high proportion share.

It is worth mentioning that reliability is an important dimension to measure it equipment for the telecom industry which often starts with six nines. In this respect, the distributed storage with integrated software and hardware is naturally dominant. Based on hardware optimization and long-term stability test, the failure rate of hardware level can be minimized. In addition, in the software hardware integration mode, each component is a known firmware and driver version, so it is very clear to obtain and define the information state, so it can significantly improve the fault state recognition rate, and once the components have problems, they can be obtained and processed in the first time. On the contrary, software hardware decoupling is essentially equivalent to transferring a series of work, such as software and hardware matching and optimization testing, which should have been completed by storage manufacturers, to the enterprise. Not only is the performance of the storage device not as good as that of the hardware and software integration, but also in disguised form increases the difficulty of deployment and maintenance, increases the total cost of ownership, and even has the risk of disputes among suppliers. All disputes will eventually return to the nature of business. In 5g era, driven by massive and diverse data, the market demand for exclusive hardware is continuously rising. Whether the software and hardware are decoupled or integrated, the market will make a choice.
