2021 Yunqi Conference丨Alibaba Cloud releases the fourth-generation Shenlong architecture, providing the industry's first large-scale flexible RDMA acceleration capability

Introduction to On October 20th, at the 2021 Hangzhou Qida Cloud Conference, Alibaba Cloud released the fourth-generation Shenlong architecture, upgraded to a new eRMDA network architecture, which is the industry's first large-scale flexible RDMA acceleration capability.

On October 20th, at the 2021 Hangzhou Qidayun Conference, Alibaba Cloud released the fourth-generation Shenlong architecture. Compared to the previous generation, fourth-generation architecture to enhance performance basis Dragon , storage IOPS increasing by 300% network PPS increase of 100%, reduce network latency% 80, also upgrade to the new network architecture eRMDA , is the industry's first A large-scale flexible RDMA acceleration capability of , once again achieved a leap in performance.

The storage IOPS reached 3 million, the network PPS reached 50 million, and the network delay was as low as 5 microseconds. Alibaba Cloud's fourth-generation dragon architecture's multiple indicators have once again refreshed the industry's highest level. Based on the leading basic performance, the fourth-generation dragon will bring further performance improvements for common applications such as databases, AI, and big data: MySQL database performance is increased by 60%, and Nginx SSL scenarios are increased by up to 420%.

The dragon architecture is a new generation of integrated software and hardware virtualization technology , which is self-developed by Alibaba Cloud. The virtualization is offloaded with a dedicated chip for processing, and the hardware acceleration IO engine . It has ultra-high performance and flexibility, and is the best cloud native. Carrier: In terms of security, the latest generation of Dragon is equipped with enterprise-level security chips, equipped with trusted computing and encrypted computing capabilities, to achieve system credibility, tamper-proof, and data availability invisible. Among them, the unique flexible RDMA acceleration capability of the fourth-generation Shenlong architecture will benefit the majority of Internet applications.

Elastic RDMA, referred to as eRDMA, is China's first large-scale RDMA acceleration capability on the cloud, which can greatly improve the communication efficiency of large-scale distributed computing, and can dynamically expand with the cluster scale of Alibaba Cloud, and can easily build China's largest RDMA distributed Computing network.

With the exponential expansion of the amount of Internet data, the scale of distributed computing in data centers has become larger and larger, and the overhead of large-scale data transmission between large-scale clusters has also increased. Compared with the traditional TCP network, elastic RDMA can greatly reduce the network communication delay caused by large-scale cluster network interconnection, greatly improve the performance and cost-effectiveness of distributed computing, and help build a larger scale and support larger data volume on the cloud. Distributed computing applications.

In the AI deep learning scenario , eRDMA can improve the training performance of large-scale distributed NLP and visual computing by 30%; in the Spark big data scenario , it improves the computing performance of Spark large-scale distributed big data by 30%; in Redis The KV database scenario can increase the throughput of Redis mixed read and write by up to 130%.

eRDMA allows RDMA networks to move from niche AI and HPC applications to supporting general-purpose computing scenarios, which will bring innovations in computing architecture, and will empower the development of cloud-native technologies such as Microservice, Serverless, and Service Mesh.

Since its launch in 2017, Alibaba Cloud cloud servers have been based on the self-developed Dragon architecture, and unified support for flexible bare metal, virtual machines, and flexible container instances, and other flexible computing product forms, serving medical care, new government affairs, intelligent manufacturing, the Internet, education, etc. Industries. Jiang Jiangwei, head of Alibaba Cloud's basic product division, said that based on the Shenlong architecture, and Alibaba Cloud will continue to promote the inclusive of high-quality computing power and continue to provide the driving force for social innovation .
