VCF 3.8/3.9 hardware requirements updated: New sizing options for the Management Domain

When it comes to sizing a VMware Cloud Foundation environment you have to take into account the specific requirements that are applicable to the Management- and Workload Domain:

1. The Management Domain consists of (at least) 4 vSAN Ready Nodes (Hybrid or All Flash) with at least 192 GB RAM per node and 2x 10Gbit (or higher);
2. A Workload Domain consists of (at least) 3 nodes with no specific memory requirements, but always requires 2x 10 Gbit (or higher) NICs.

My colleague Maurice de Haan pointed me on a minor change in the hardware requirements for the Management Domain since VCF 3.8, which provides some new sizing options.

VCF pre-3.8 documentation states:

While VCF 3.8 and later tells:

Note: This specific CPU requirement only existed for the management domain.

The dual socket requirement for All Flash vSAN Ready Nodes in the Management Domain was dropped. This means you can now follow the minimum requirements for vSAN Ready Nodes as detailed in the vSAN documentation. You can choose for a single socket All Flash vSAN node in the Management Domain, as long it is on vSAN Compatibility Guide (and there are a few).
