General Computing DCCs

Overview

General-computing DCCs 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. ECSs can support regular workloads and cope with short-term load surges.

General computing DCCs are classified into s3, s7, s3_pro, s6, and s6_pro types, providing better cost-effectiveness. S3, S7, and S6 ECSs can be deployed on the general computing DCCs.

The number of vCPUs for a DCC is calculated as follows: Number of vCPUs = (Number of sockets x Number of cores x Number of single-core threads – CPU overheads) x CPU overcommitment ratio

  • s3 DCCs

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

  • s3_pro DCCs

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

  • s6 DCCs

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

  • s6_pro DCCs

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

  • s7 DCCs

    vCPUs = (2 x 38 x 2 – 22) x 3 = 390
