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 are classified into the following types: c3, c3_pro, c3ne, c6, c6_pro, and c7n_pro.

Both c3 and c3_pro DeHs house C3 ECSs. C3 ECSs come with the latest Intel Xeon Skylake CPUs and high-performance networks for enterprise-level applications that require enhanced service stability and improved computing performance.
c3ne DeHs house C3ne ECSs. C3ne ECSs come with the latest Intel Xeon Skylake CPUs and 25GE high-speed iNICs to offer an intranet bandwidth of up to 40 Gbit/s and network forwarding capacity of up to 10 million packets per second (PPS), thereby addressing the requirements of enterprise-level applications on high computing and network performance.
Both c6 and c6_pro DeHs can house C6 ECSs.
c7n_pro DeHs can house c7n ECSs.

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

c3 DeHs
vCPUs = (2 x 18 x 2 – 12) x 1.07 = 64
c3_pro DeHs
vCPUs = (2 x 18 x 2 – 12) x 1.07 = 64
c3ne DeHs
vCPUs = (2 x 18 x 2 – 12) x 1.07 = 64
c6 DeHs
vCPUs = (2 x 22 x 2 – 14) x 1 = 74
c6_pro DeHs
vCPUs = (2 x 22 x 2 – 14) x 1 = 74
c7n_pro DeHs
vCPUs = (2 x 28 x 2 – 14) x 1 = 98
