General Computing-Plus DeHs

Overview

Compared with general computing DeHs, general computing-plus DeHs provide dedicated vCPUs, featuring powerful performance. In addition, the DeHs 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 DeHs include only c4 DeHs.

• C4 ECSs can be deployed on c4 DeHs.

DeH Specifications

Table 1 Specifications of c4 DeHs

Flavor Type	Number of CPUs (Sockets)	Number of Physical Cores	Hardware Specifications	vCPUs
c4	2	22	CPU: Intel Cascade Lake 6266 (frequency: 3.00 GHz; Turbo frequency: 3.40 GHz) Memory: 296 GB (or 303,104 MB)	74

Note

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

• c4 DeHs

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