Dedicated General-Purpose DeHs

Overview

Dedicated general-purpose DeHs are classified as c3 and c4 DeHs. DeHs of c3 and c4 types can be used to deploy C3 and C4 ECSs. The C3 and C4 ECSs use high-performance networks to improve comprehensive performance and stability, meeting the requirements of enterprise-level applications for high service stability and computing performance.

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

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

  • c3 DeHs: vCPUs = (2 x 18 x 2 – 12) x 1 = 60
  • c4 DeHs: vCPUs = (2 x 22 x 2 - 14) x 1 = 74
