General Computing-Plus DeHs

Overview

Compared with general computing DeHs, general computing-plus DeHs provide dedicated vCPUs, featuring powerful performance. In addition, the DeHs use latest-generation network acceleration engines and Data Plane Development Kit (DPDK) to provide higher network performance, meeting requirements in different scenarios.

General computing-plus DeHs include only c4 DeHs.

  • C4 ECSs can be deployed on c4 DeHs.

  • CPU: Intel Cascade Lake 6266 (frequency: 3.00 GHz; turbo frequency: 3.40 GHz)
  • Memory: 296 GB (or 303,104 MB)

74

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

  • c4 DeHs

    vCPUs = (2 x 22 x 2 – 14) x 1 = 74
