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

Overview

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

You can select a dedicated host type based on its supported ECS instance families. Dedicated host types are inherited from the corresponding ECS instance families that are available on shared hosts. You can create ECS instances on a dedicated host of the same type. For example, you can create all ECS instances of the sn1ne instance family on dedicated hosts of the Compute Optimized Type with Enhanced Network Performance. For more information about ECS instance families and the corresponding network performance, see Instance families.

Types

The following table lists the dedicated host types that are currently supported.
Note

The storage-enhanced g5se and network-enhanced g5ne host types are under invitational preview. If you want a chance to be considered for a preview, you can submit a ticket.

*Number of vCPUs = Number of CPU cores × 2 - Number of vCPUs reserved by the host

**Number of vCPUs = (Number of CPU cores × 2 - Number of vCPUs reserved by the host) × CPU overprovisioning ratio

****Note: The total packet forwarding rate or bandwidth of all ECS instances on a dedicated host cannot exceed the capacity of the host. For more information about the network performance of ECS instance families, see Instance families.
