Hi Graeme, thanks very much for this ! So the following paragraph :
Management components can be co-hosted on the same vSphere cluster as the end-user resources if desired. This architecture is more typical in smaller environments or where the use of converged hardware is used and the cost of providing dedicated hosts for management is too high. If you place everything on the same vSphere cluster, you must configure the setup to ensure resource prioritization for the management components. Sizing of resources (for example, virtual desktops) must also take into account the overhead of the management servers. See VMware vSphere Resource Management for more information.
In summary, stipulats that vSphere & Horizon can be managed by the same vCenter server which is managing the same cluster, correct? Does this apply to Horizon 8 ? Thanks very much James
