High-end all-flash memory ushered in architectural change

Some people say that high-end storage is dead, but it is not.

It is inevitable that the traditional high-end storage based on HDD or mixed media will decline. As early as 2016, Gartner predicted that traditional high-end storage would be replaced within 2-5 years. The replacement is high-end storage based on all-flash memory. In recent years, high-end all-flash storage has shown unprecedented vitality and achieved high market growth. The reason for this is that high-end storage with high reliability, high performance, high availability and high consistency is an important feature different from other storage systems, and still has important value in critical business scenarios.

Architecture is the soul of high-end storage. However, when the high-end storage is moving towards flash memory in an all-round way, the architecture of high-end storage still has not made a major breakthrough. The mainstream high-end storage products in the market, whether using directly connected matrix architecture or switching architecture, have not achieved a major breakthrough over the years. For example, high-end storage products using Scale-Up vertical expansion have high stability and reliability, but their scalability can not keep up with the changes of current business requirements; while high-end storage products based on dual-control Scale-Out scale-out solve the problem of scalability, but do not reach the extreme in reliability.

It is a general trend to change the high-end storage architecture. On the one hand, because of the historical burden, the compromise in the storage architecture of high-end storage products brings about a compromise in software function and performance, which can not give full play to the advantages of flash memory; on the other hand, business applications tend to be diversified. the new requirements for data storage are also driving the transformation of high-end storage architecture. As Zhou Yuefeng, vice president of Huawei's IT product line and president of intelligent data and storage, said: "in the smart era, diverse data fusion processing makes storage face new challenges and requirements."

Today, the launch of OceanStor Dorado V6 means that Huawei is the first to take an important step in the transformation of high-end storage architecture in the market.

Soul of SmartMatrix:OceanStor Dorado V6

Huawei OceanStor Dorado V6 SmartMatrix architecture combines the advantages of Scale-Up and Scale-Out architecture. A single system can scale up to 32 controllers and greatly improve end-to-end reliability. It can achieve controller 8 bad 7, business interruption-free, 99.9999% high availability, and can perfectly host core business application scenarios such as finance, manufacturing and operators.

The reason why SmartMatrix can achieve a breakthrough in high-end storage architecture is that it adopts the architecture of separation of computing and storage, the controller engine is completely separated from the hard disk frame, and all engines are directly interconnected with the hard disk frame. The biggest benefit of this architecture is that the controller and storage can be expanded and upgraded independently, which not only greatly improves the flexibility of the storage system, but also brings long-term investment protection to users, reduces storage risk and improves business continuity.

In addition, the storage controller engine uses a fully interconnected front and rear architecture, and a single engine supports 4 control nodes and 28 IO interface modules. Moreover, the interface card is fully interconnected with the node, and the failure of a single node will not cause the interface card to disconnect. Cache architecture uses global memory and multi-copy technology, all nodes share Cache, and can tolerate dual control failure at the same time.

The author believes that in the past few years, the market has realized the limitations of high-end storage architecture, and the reason why it has not made a big breakthrough is that manufacturers have a heavy historical burden, and the cost and risk of innovation are too high. as a result, the high-end storage architecture has been slowly evolving in the all-flash era, often with small steps of improvement. Therefore, the innovation and breakthrough of architecture is often an arduous task, which often requires a comprehensive breakthrough in machine design, component innovation, core chips and software, so as to achieve the architectural breakthrough of the whole storage system.

Huawei OceanStor Dorado V6 SmartMatrix architecture officially achieves a breakthrough in the entire architecture with a point-by-point approach and a comprehensive approach.

First of all, the design and implementation ability of the whole system. Huawei has the best hardware design capability in the industry. The SmartMatrix architecture implements a fully symmetrical AA architecture in the control layer, and the front and rear ends are fully IP interconnected, all support 100GE RoCE interconnection, and also achieve end-to-end NVMe-of. These enable OceanStor Dorado V6 to hold four quad nodes at a height of 4U, and achieve switch-free full interconnection, while providing 28 IO interface cards, all interface cards are fully interconnected with four nodes, and the distributed standby power capability allows the whole system to have excellent power performance.

Secondly, the innovation ability of the core components of the system. Huawei OceanStor Dorado V6's SmartMatrix architecture uses a groundbreaking intelligent hard drive frame with a built-in processor to load workloads such as encryption, compression, data verification, hard disk reconstruction and fault prediction from the controller engine to the hard disk frame, making daily data processing more efficient.

Third, core chip capability. Huawei OceanStor Dorado V6 uses five self-developed chips: intelligent multi-protocol interface chip, intelligent processor chip, intelligent AI chip, intelligent SSD control chip and intelligent BMC management chip. The addition of Kunpeng 920 and Teng 310AI chips has greatly improved the data processing performance. Huawei made the five chips fit perfectly in the storage system, which also improved the performance of the whole system as never before.

The last part is the ability of software adaptation and optimization. Huawei OceanStor Dorado V6 has been redesigned from the underlying storage OS, software functions, etc., using a multi-dimensional balanced distributed architecture, so that it can match the overall hardware architecture, give full play to the software capabilities.

It can be said that SmartMatrix is the soul of OceanStor Dorado V6, and the innovation and breakthrough it brings will determine the height in the future market.

OceanStor Dorado V6: set a new benchmark for all-flash memory

With the blessing of the core SmartMatrix architecture, Huawei OceanStor Dorado V6 has achieved many leading features and really set a new benchmark for all-flash memory. For example, OceanStor Dorado V6 can achieve a stable delay of 20 million IOPS and 0.1ms, which can meet the performance requirements of real-time services, while SmartMatrix architecture brings high reliability with zero fault perception, zero service impact and zero upgrade impact, and can achieve a single system to tolerate up to seven controllers to fail at the same time, making the business truly permanent online. The addition of AI chips and the AI engine OceanStor DJ enable intelligent management of planning, deployment, distribution, operation and maintenance, and optimization throughout the life cycle.

In addition, according to Huawei, the performance impact of OceanStor Dorado V6 can be controlled within 10 per cent when all features are turned on, compared with an industry average of 30 per cent.

Zhou Yuefeng, vice president of Huawei's IT product line and president of intelligent data and storage, said bluntly that OceanStor Dorado V6 is an important embodiment of Huawei's "data + intelligence" concept. "the data infrastructure needs to be redefined because different types of data require diverse computing power, data access needs to be smarter, storage architectures need to move towards convergence, and data processing platforms need to be aware of upper-layer applications," he says. "

"Huawei OceanStor Dorado V6 is flash inclusive, automated, cloud-based and fully converged storage, which will play an important role in the implementation of data infrastructure in the smart era." Zhou Yuefeng said.

Write at the end

Uncompromising, this is the most prominent label of Huawei OceanStor Dorado V6 in the all-flash era.

It can be said that OceanStor Dorado V6 represents a new direction, with a new attitude and advantages to help users meet the coming data challenges, will accelerate China to enter the era of flash memory inclusive.
