Overview

The DeH category and type define the DeH configuration and determine the type and number of ECSs you can create on the DeH.

The DeH configuration includes the number of CPUs (sockets), number of physical cores, local storage, hardware configuration (CPU model and memory size), and number of vCPUs. Buy DeHs of desired specifications based on the site requirements.

Currently, the following DeH categories and types are supported:

  • General computing DeHs
  • General computing-plus DeHs
  • Memory-optimized DeHs

DeH categories here are for your quick glance only. For details about each DeH category, go to the specific topics.

The number of vCPUs for a DeH 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

  • s3 and s3_pro DeHs

    vCPUs = (2 x 22 x 2 - 16) x 2 = 144

  • s6 and 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

  • c3, c3_pro, and c3ne DeHs

    vCPUs = (2 x 18 x 2 - 12) x 1.07 = 64

  • c6 and 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

  • m3 DeHs

    vCPUs = (2 x 18 x 2 - 12) x 1.07 = 64

  • m6 DeHs

    vCPUs = (2 x 22 x 2 - 12) x 1 = 76
