Memory-Optimized DeHs

Overview

Memory-optimized DeHs are designed for processing large-scale data sets in the memory. They use the latest Intel Xeon Skylake CPUs, network acceleration engines, and Data Plane Development Kit (DPDK) to provide higher network performance, providing a maximum of 512 GB DDR4 memory for high-memory computing applications.

Memory-optimized DeHs are classified into m3 and m6 DeHs.

  • M6 ECSs can be deployed on m6 DeHs.

Number of vCPUs = (Number of sockets x Number of cores x Number of single-core threads - CPU overheads) x CPU overcommitment ratio

  • m3 DeHs

    vCPUs = (2 x 18 x 2 - 12) x 1.07 = 64

  • m6 DeHs

    vCPUs = (2 x 22 x 2 - 12) x 1 = 76
