General Computing-plus DCCs

Overview

Compared with general computing DCCs, general computing-plus DCCs provide dedicated vCPUs, featuring powerful performance. In addition, the DCCs 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 DCCs are classified into c7, c7_pro, c7_a, c7_b, c3, c3_pro, c6, and c6_pro types. C3, C7, and C6 ECSs can be deployed on the general computing-plus 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

  • c3 DCCs

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

  • c3_pro DCCs

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

  • c3ne DCCs

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

  • c6 DCCs

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

  • c6_pro DCCs

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

  • c7 DCCs

    vCPUs = (2 x 32 x 2 – 0) x 1 = 128

  • c7_pro DCCs

    vCPUs = (2 x 32 x 2 – 0) x 1 = 128

  • c7_a DCCs

    vCPUs = (2 x 38 x 2 – 0) x 1 = 152

  • c7_b DCCs

    vCPUs = (2 x 38 x 2 – 0) x 1 = 152
