You can configure your values at a global level that are applicable for all the workloads that you want the sizer to calculate.
- SDDC Appliance Size
- You can select the required size from the drop-down menu. By default, sizer uses the Auto option, which selects the SDDC Appliance based on your current workload needs. The literal size of the management appliances to be deployed. You can check the recommended SDDC under Additional Info > SDDC & Cluster.
- Stretched Cluster
- You can select Yes if you want to use a stretched cluster. Storage preference is automatically set to vSAN only for all workload profiles, if you choose to use a stretched cluster.
- Fault Tolerance
- Fault tolerance refers to the vSAN Fault Tolerance configuration. By default, the sizer uses the Auto mode based on SLA-specific managed storage policy recommendations. You can check the recommended fault tolerance policy under Additional Info > Headroom & vSAN Policy. With fault tolerance, you can override the behavior and force a particular configuration. You have the choice of setting Failure to Tolerate (FTT) and Failure Tolerance Method (FTM) to specific values or letting the VMC Sizer automatically determine the settings that can minimize the number of hosts in the recommendation while also complying with the VMC SLA requirements.
- CPU Headroom
- You can enter a valid number to define the headroom. The CPU headroom represents a reserved CPU cores in the SDDC.
- Hyper-threading weight (%)
- You can configure Hyper-Threading weight percentage in Global Settings which can be considered for any host type that supports hyper-threading.
Note: The global setting is applicable to manual and import method of the sizer tool.
