Manual advanced sizing is appropriate for new deployments where the workload requirements are well understood. Advanced sizing require additional information but allow complete customization and are suitable when dealing with any well-understood application.


  1. Open on a new browser.
  2. On the VMware Cloud Advanced Sizer, click Get Started and choose Manual.
  3. Select the relevant Workload Type from the drop-down menu.
  4. The profile name is provided with a default name.
  5. Under the Sizer Input, enter the Total number of VMs and you can modify the vCPU/pCore based on your requirement.
    For VDI workload types, you can consider one VM per desktop instance. vCPU/pCore represents the share of virtual CPU per physical CPU.
    Note: The vCPU/pCore option is not provided when you select the workload type as VDI – Full Clone and VDI Instant Clone. For more information on Workload type, see Access VMware Cloud Quick Sizer.
    1. Select Additional tab, when you want to enter more resource entries about the current CPU utilization, memory, storage and I/O related to your workload. Although the values entered are pre-defined by the sizer, if required, you can still continue to modify the values.
  6. Enter the required Input Average.
    1. vCPUs/VM - Represents the share of a virtual CPU per VM.
    2. vRAM/VM - Represents the amount of virtual RAM allocated per VM.
    3. Utilized Storage/VM - Represents the value for total storage needs per VM. The total storage includes storage taken up by the operating system as well as the storage required for all the applications running on the VM.
    Note: The sizer provides additional feature where you can enter an average of your input values. If you are not sure of the average values, then you can enter the input totals.
  7. You can add a new workload profile or duplicate the existing one. Click Add Another Workload Profile.
    1. To manually enter data, click Manual Data.
    2. To import an existing data, click Import Data > RV Tools or Live Optics. For more information on RV tools and Live Optics, see VMware Cloud Advanced Sizer - VDI.
    1. Under the Recommendation section, you can view the calculation displayed for the entered resources. You can also select the Host type (AWS) from the drop-down to reflect the requirement for the selected host type. For more information on host types, see VMware Cloud on AWS Host Type. The current options provided for host type is i3 instance type and i3en instance type.
    2. The Additional Info section provides information related to a detailed breakdown of how the values were calculated for the resources, SDDC and Cluster, Headroom and vSAN policy, and other Sizing Assumptions that were considered. Each of the break up given in this section is based on the inputs that you have provided while calculating the resource estimation for your deployment.
  9. To download the report, click Download report (PDF).
    Note: Your downloaded report is valid up to 30 days only.
  10. To request a Total Cost of Ownership (TCO) for an estimated VMware Cloud on AWS SDDC, click GET TCO, and select Request TCO over email.
    1. Enter your Name, Company name and Contact details.
    2. Enter the required sizing details and click Save. Once you save, a request is created with your sizing requirements and VMware professionals will get back to you. To generate the report, the VMware Cloud sizer sends an email to the TCO team with the required details.
  11. You can also build your own TCO, click Build your own TCO.
    Note: The sizer tool also allows you to save your entries as a project. For more information on project workflow, see Create and Save Your Sizer Project in VMware Cloud sizer.
