This post contains some sample high level architecture diagrams that I have put together for enablement purposes.
These are not official Dell EMC VCF on VxRail architecture diagrams. I put these together because I wanted something that I could talk to, at this level of detail. And I am simply sharing them for others to use as required (assuming that someone else likes them enough to use them!).
These diagrams are reflective of VCF 3.9.0/3.9.1 on VxRail. Go here for VCF 4 on VxRail diagrams.
As a brief explanation of some of the colour scheme, some of the VCF Management WLD components have a green outline, as these components are responsible for deploying other components in VCF. More detail about that here.
Updated Jan 24th 2020
The replicated components, as well as the replication mechanism itself (SRM), are denoted by a red outline, with the grey items representing placeholder VMs on Target DR Site.
Note: DR for NSX-T is not supported at the time of updating this post
Single Site + Remote WLD (not supported)
Update 1/5/2020 – I have included this architecture specifically to call out that it is currently NOT SUPPORTED by VMware (and therefore VxRail). This architecture is often requested, but as yet is not documented by VMware in the context of a VVD or VCF architecture.
Hopefully it helps others!
