General Computing DeHs

Overview

General-computing DeHs can accommodate ECSs with regular workloads and short-term workload surges. They use a CPU-unbound scheduling scheme. vCPUs are randomly allocated to idle CPU hyper threads based on the system loads. If traffic loads are light, the computing performance is high. However, if traffic loads are heavy, vCPUs of different ECSs compete for physical CPU resources, resulting in unstable computing performance.

General computing DeHs are classified into s3, s3_pro, s6, s6_pro, s7, and s7n types, and use the latest-generation Intel® Xeon® SkyLake CPUs, providing better cost-effectiveness. S3, S6, S7, and S7n ECSs can be deployed on the general computing DeHs.

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

s3 DeHs
vCPUs = (2 x 22 x 2 – 16) x 2 = 144
s3_pro DeHs
vCPUs = (2 x 22 x 2 – 16) x 2 = 144
s6 DeHs
vCPUs = (2 x 26 x 2 – 16) x 3 = 264
s6_pro DeHs
vCPUs = (2 x 26 x 2 – 16) x 3 = 264
s7 DeHs
vCPUs = (2 x 38 x 2 – 22) x 3 = 390
s7n DeHs
vCPUs = (2 x 28 x 2 – 20) x 3 = 276
