Change cloud server configuration

In a cloud server, you can change the configuration and number of resources:

  • select a different lineup and fixed configuration (except GPU lineup);
  • change the fixed configuration to an custom configuration (except for the GPU lineup);
  • change the number of resources in fixed or custom configuration - vCPU, RAM, local disk size;
  • change an custom configuration to a fixed configuration.

A cloud server configuration with a local disk cannot be changed to a configuration without a local disk and vice versa.

Graphics processors can be added to servers of custom configuration.

When you change the configuration, all data on the cloud server is saved.

    5.1 Expand the block describing the configuration settings.

    5.2 Optionally: select the processor manufacturer. Manufacturer selection is not available in all pools.

    5.3. Optional: If you want the vCPU of the cloud server to be assigned to the physical CPU cores, check the **Dedicated Co **res checkbox.See the Dedicated Co res instruction for details.
    If the cloud server has dedicated cores and you need to disable them, clear the checkbox Dedicated cores.

    5.4 Optional: If the cloud server has dedicated cores and you want to enable Hyper-Threading, check the Hyper-Threading (SMT) checkbox.To disable hyperthreading, clear the Hyper-Threading (SMT) checkbox .

    5.5 Optional: If the cloud server has dedicated cores and you want to place the CPU resources on a single NUMA node, check the Mandatory placement on a single NUMA node checkbox.To not place the cloud server resources on a single NUMA node, clear the Mandatory placement on a single NUMA node checkbox .If cloud server resources cannot be placed on a single node, the modified configuration will not apply.For more information, see the Placement on a single NUMA node subsection of the Dedicated Cores instruction.

  6. Specify the number of resources required.
