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¶
Flavor Type | Number of CPUs (Sockets) | Number of Physical Cores | Hardware Specifications | vCPUs |
---|---|---|---|---|
c4 | 2 | 22 |
| 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
