Horizon 7 Sizing and Consumption Model : 7.3 Infrastructure Blueprints
   
7.3 Infrastructure Blueprints
Each tenant blueprint defines the sizing constants and specification of hosts in the resource cluster, primarily compute and storage. These values will be used to calculate the resource capacity for each tenant, and will reflect the service levels for a given tenant.
In the following examples, a single blueprint will be used (Blueprint 1), and will be based on the Silver SLA as outlined in Section 9, Service Levels.

Note Additional host blueprints can be specified for features such as vGPU, vSAN All-Flash vs Hybrid and varying CPU / Memory specifications, in addition to different service levels (Bronze, Silver, Gold, Platinum).

The maximum host memory and CPU utilization stated here is an example. Other environmental factors such as overheads running NSX and vSAN will need to be considered.
