Kunpeng General Computing-plus DCCs

Overview

Kunpeng general computing DCCs use Kunpeng 920 processors and 25GE high-speed intelligent NICs to cost-effectively provide a baseline level of vCPU performance with the ability to burst above the baseline, meeting the requirements of migrating infrastructure services to the cloud.

Kunpeng general computing-plus DCCs are classified into kc1 and kc1_pro. They can be used to house kC1 ECSs.

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

  • kc1 DCCs

    vCPUs =(2 x 64 x 1 – 12) x 1 =116

  • kc1_pro DCCs

    vCPUs =(2 x 64 x 1 – 12) x 1 =116
