Executive Summary
Whether for emerging industries such as Internet, big data, and artificial intelligence, or traditional sectors such as finance, medicine, and manufacturing, cloud services have gradually become one of the standards for the next-generation IT infrastructure. Cloud storage products and solutions such as cloud disks will be an important carrier of future business data, so their performance is a key factor to consider for enterprises when choosing cloud services.
Tencent Cloud's CBS performs well across various business scenarios, including the high-load Online Transaction Processing (OLTP) financial transaction systems, high-throughput e-commerce systems, data analytics systems for artificial intelligence, and high-concurrency CDN, etc. Its performance has received positive feedback from customers.
Based on the CBS architecture, storage engine, and hardware infrastructure, Tencent Cloud introduced the Remote Direct Memory Access (RDMA) protocol and partnered with Intel to carry out comprehensive optimizations, including introducing the Storage Performance Development Kit (SPDK) provided by Intel, to optimize the IOPS and latency of NVMe SSDs.
After optimizations on the architecture, engine, and software, Tencent and Intel found the latency of the SSD itself can also be an obstacle for further performance enhancement. The most effective solution to address the issue is to find a storage medium with better performance.
Therefore, Tencent Cloud and Intel leveraged Intel® Optane™ Technology, a cutting-edge memory and storage technology, and used Intel® Optane™ Persistent Memory as the storage core of the next-generation ultra-fast CBS. They also reconstructed how data is written to the storage medium to meet the latency requirement in performance-intensive scenarios.
