Dedicated Host:Dedicated host types

Last Updated:Feb 10, 2025

The type of a dedicated host determines the type and number of ECS instances that you can create on the dedicated host. This topic describes the types of dedicated hosts.

Overview

The type of a dedicated host refers to the physical server specifications of the dedicated host. The specifications include the CPU model, memory capacity, local storage space, number of CPU cores, number of CPU sockets, and number of vCPUs.

The predefined ECS instances on a dedicated host can be used in the same scenarios as the ECS instances on a shared host. Therefore, you can create ECS instances on a dedicated host whose type is compatible with the ECS instances. For example, you can create all types of ECS instances which belong to the g6, c6, r6, and ic6 instance families on a General-purpose g6 dedicated host. For more information, see Overview of instance families.

Custom instance types allow you to customize the vCPU-to-memory ratio. For example, you can create custom types of ECS instances on a dedicated host whose type is General-purpose Overprovisioned g6s. You can also change the number of vCPUs and the memory size.

Available types

The available types include overprovisioned, enhanced, general-purpose, memory-optimized, compute-optimized, and local disk types. The performance of different types may vary. When you purchase a dedicated host, select the type that best suits your needs.

Note

The following information explains the columns marked with ①, ②, ③, and ④ in the tables.

  • ①: Number of vCPUs for non-overprovisioned type = Number of CPU cores × 2

  • ②: Number of vCPUs for overprovisioned type = Number of CPU cores × 2 × CPU overprovisioning ratio

  • ③: For information about local disks, see Local disks.

  • ④: The total packet forwarding rate or bandwidth of all the ECS instance types on a dedicated host must be less than that of the dedicated host. For information about the network performance of all the ECS instances, see Overview of instance families.
