General-Purpose DeHs

Overview

General-purpose DeHs can accommodate ECSs with regular workloads and short-term workload surges. They use a CPU-unbound scheduling scheme. vCPUs are randomly allocated to idle CPU hyper threads based on the system loads. If traffic loads are light, the computing performance is high. However, if traffic loads are heavy, vCPUs of different ECSs compete for physical CPU resources, resulting in unstable computing performance.

Currently, only the s3, s6, and s6_pro DeH types equipped with the latest-generation Intel® Xeon® Skylake CPUs, providing better cost-effectiveness, are provided and can be used to deploy S3 and S6 ECSs.

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

  • s6 DeHs

    vCPUs = (2 x 26 x 2 – 16) x 3 = 264

  • s6_pro DeHs

    vCPUs = (2 x 26 x 2 – 16) x 3 = 264

  • s3 DeHs

    vCPUs = (2 x 22 x 2 – 16) x 2 = 144
