A Cloud Foundation rack can contain 4 to 32 heterogeneous servers. Servers must be from the same vendor, but can be of different models and sizes with variable CPU, memory, storage size and type, and disk configurations (e.g. hybrid or all flash).

You can select the servers you want to use for the management domain as well as workload domains. This gives you the flexibility to use say hybrid servers for the management domain and all flash servers for workload domains.

For information on supported hardware, see VMware Compatibility Guide.
