About the VMware Validated Design Sizing Tool

Welcome to the update release of the Sizing Tool with support for VMware Validated Design for the Software-Defined Data Center, versions 2.0, 3.0, 4.0, 4.1, 4.2, 4.3 and 5.0 and for the VMware Validated Design for Workload and Management Consolidation, versions 4.1, 4.2, 4.3 and 5.0. See also http://www.vmware.com/go/vvd for more information about the designs.

Note the following features for the Sizing Tool.

The Sizing Tool allows for 1 or 2 region sizing for VMware Validated Designs for SDDC, versions 2.0, 3.0, 4.0, 4.1, 4.2, 4.3 and 5.0. In 4.x sizing is for a two pod design which allows for a single rack with a shared compute and edge pod and one or more racks dedicated to compute. VMware Validated Designs for SDDC 4.2 and later allows for multiple Availability Zones in Region 1.
The Sizing Tool allows for single region, one pod sizing, with the VMware Validated Design for Workload and Management Consolidation, versions 4.1, 4.2, 4.3 and 5.0. This design allows for up to 32 hosts and up to 1500 Virtual Machines in a single region. Management, edge, and compute are co-located in the same pod.
The Sizing Tool offers three selections for hardware - Certified Hardware from the VMware Compatibility Guide, Generic Hardware with vSAN and Generic Hardware with External Storage. The Certified Hardware is limited to Certified Ready Node systems listed on the vSAN Compatibility Guide.
Sizing for vSAN with RAID 5/6 on all flash configurations will assume dedupe and erasure coding.
Users may input a memory overcommit ratio for a workload. This value can be a decimal and has a default of 1, which means that memory is not overcommitted.
Users may input a cpu overcommit ratio for a workload. This is of the form X:1 where X is the number of vCPU that is mapped to a logical processor. The number of logical processors for a system is the number of hyperthreads for that system. The default ratio is an integer value set at 4 vCPU per logical processor. An overcommit value of 1 means that the cpu is not overcommitted for the workload.
Users may input a User Workload VM to Edge VM ratio. This is of the form X:1 where X is the number of user VMs mapped to a single Edge VM. This value is an integer and the default is set at 10 user VMs to a single Edge VMs.
Sizing is generated for the specified workloads and is approximate in nature. The sizing output should be used as a guideline only.
Users can display results in Gigabytes or Terabytes.
The Sizing Tool output may be downloaded as a pdf or csv file

Known Issues

This release of the VMware Validated Design Sizing Tool has the following known issues

Problem: Using browser cached input for numeric input values may not work properly (Safari).
Workaround: Type in the appropriate input values desired or use non-cached dropdown list values to provide numeric input values to the tool.
Problem: Selecting the CPU with a specific Vendor name does not filter the list of CPUs for only that Vendor.
Workaround: Select the Vendor name only and select the specific model of the desired server.
Problem: Some certified servers may not have a 2U form factor.
Workaround: None. Check all servers of interest that they have the appropriate form factor for the intended use.

Problem: Selection of certified servers via the memory selection may not populate the correct result.
Workaround: Select by the Vendor name for servers of interest. Memory will be listed in the detail section of the system.
