Memory-optimized ECSs

Overview

Memory-optimized ECSs have a large memory size and provide high memory performance. They are designed for memory-intensive applications that process a large amount of data, such as precision marketing, e-commerce, and IoV big data analysis.

M7n ECSs use third-generation Intel® Xeon® Scalable processors to provide enhanced computing, security, and stability. They can have a maximum number of 96 vCPUs and a memory speed of 3200 MHz, and provide a secure and trusted cloud environment for memory-intensive computing applications.

M6 and M6nl ECSs use second-generation Intel® Xeon® Scalable processors with technologies optimized to offer powerful and stable computing performance. Using 25GE high-speed intelligent NICs, M6 ECSs provide a maximum memory size of 512 GiB based on DDR4 for large-memory applications with high requirements on network bandwidth and packets per second (PPS).
