Memory-optimized ECSs

Updated at: Sep 12, 2019 GMT+08:00

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 advertising, e-commerce big data analysis, and IoV big data analysis.

  • M3 ECSs are developed based on the KVM virtualization platform and designed for processing large-scale data sets in the memory. They use latest-generation Intel Xeon Skylake CPUs, network acceleration engines, and DPDK rapid packet processing mechanism to provide higher network performance, providing a maximum memory size of 512 GB based on DDR4 for high-memory computing applications.
  • M2 ECSs use Intel Xeon E5-2690 v4 CPUs and are designed for memory-optimized applications.

Scenarios

  • Applications

    Memory-optimized ECSs are suitable for applications that process large volumes of data and require a large amount of memory, rapid data switching and processing, and low-latency storage resources.

  • Application scenarios

    Big data analysis, precision advertising, e-commerce big data analysis, IoV big data analysis, relational databases, NoSQL databases, and memory data analysis

Notes on Using M2 ECSs

  • M2 ECSs support all rollout OSs.
  • M2 ECSs do not have InfiniBand or SSD NICs configured.
  • M2 ECSs support modifying specifications if the source and target ECSs are of the same type.
  • To improve network performance, you can set the NIC MTU to 8888.

Notes on Using M3 ECSs

  • M3 ECSs support all rollout OSs.
  • M3 ECSs do not have InfiniBand or SSD NICs configured.
  • M3 ECSs support modifying specifications if the source and target ECSs are of the same type.
