This topic describes the managed rules that are related to Alibaba Cloud dedicated hosts (DDHs) and the methods to fix non-compliance issues.

ddh-cpu-min-count-limit

Checks whether the number of vCPUs for a dedicated host of your account is greater than or equal to the specified threshold value.

Trigger type: configuration change

Applicable resource type: ACS::ECS::DedicatedHost

Input parameter: cpuCount. You can specify the minimum number of vCPUs for a dedicated host.

Cause: The number of vCPUs for a dedicated host of your account is smaller than the specified threshold value. You can fix this non-compliance issue by using one of the following methods:
  • Method 1: Create a dedicated host and select a type that complies with the rule. You cannot modify the type of a dedicated host after it is created. Therefore, you must create a dedicated host that meets the requirements of Cloud Config. Cloud Config detects the configuration change and starts to re-evaluate the resource within 10 minutes.

    You can release a non-compliant dedicated host if it uses the pay-as-you-go billing method. If the dedicated host uses the subscription billing method, it cannot be manually released.

    Risks: After the dedicated host is released, the resources associated with the dedicated host become unavailable. All the data of the Elastic Compute Service (ECS) instances on the dedicated host will be cleared and cannot be restored. Before you release a dedicated host, we recommend that you migrate the ECS instances on the dedicated host to another dedicated host of your account.

    For more information, see Migrate ECS instances between different dedicated hosts.

  • Method 2: Change the value of the input parameter and click Re-evaluate on the details page of the rule.

ddh-memory-min-size-limit

Checks whether the memory size of a dedicated host of your account is greater than or equal to the specified threshold value.

Trigger type: configuration change

Applicable resource type: ACS::ECS::DedicatedHost

Input parameter: memorySize. You can specify the minimum memory size of a dedicated host. Unit: GiB.

Cause: The memory size of a dedicated host of your account is smaller than the specified threshold value. You can fix the non-compliance issues by using one of the following methods:
  • Method 1: Create a dedicated host and select a type that complies with the rule. You cannot modify the type of a dedicated host after it is created. Therefore, you must create a dedicated host that meets the requirements of Cloud Config. Cloud Config detects the configuration change and starts to re-evaluate the resource within 10 minutes.
    You can release a non-compliant dedicated host if it uses the pay-as-you-go billing method.
    Note If the dedicated host uses the subscription billing method, it cannot be manually released.

    Risks: After the dedicated host is released, the resources associated with the dedicated host become unavailable. All the data of the ECS instances on the dedicated host will be cleared and cannot be restored.

    Before you release a dedicated host, we recommend that you migrate the ECS instances on the dedicated host to another dedicated host of your account.

    For more information, see Migrate ECS instances between different dedicated hosts.

  • Method 2: Change the value of the input parameter and click Re-evaluate on the details page of the rule.

ddh-socket-min-count-limit

Checks whether the number of physical CPUs, namely CPU sockets, of a dedicated host of your account is greater than or equal to the specified threshold value.

Trigger type: configuration change

Applicable resource type: ACS::ECS::DedicatedHost

Input parameter: socketCount. You can specify the minimum number of physical CPUs.

Cause: The number of physical CPUs of a dedicated host of your account is smaller than the specified threshold value. You can fix this non-compliance issue by using one of the following methods:
  • Method 1: Create a dedicated host and select a type that complies with the rule. You cannot modify the type of a dedicated host after it is created. Therefore, you must create a dedicated host that meets the requirements of Cloud Config. Cloud Config detects the configuration change and starts to re-evaluate the resource within 10 minutes.

    You can release a non-compliant dedicated host if it uses the pay-as-you-go billing method. if it uses the pay-as-you-go billing method. If the dedicated host uses the subscription billing method, it cannot be manually released.

    Risks: After the dedicated host is released, the resources associated with the dedicated host become unavailable. All the data of the ECS instances on the dedicated host will be cleared and cannot be restored.

    Before you release a dedicated host, we recommend that you migrate the ECS instances on the dedicated host to another dedicated host of your account.

    For more information, see Migrate ECS instances between different dedicated hosts.

  • Method 2: Change the value of the input parameter and click Re-evaluate on the details page of the rule.
