Combining management infrastructure and virtual desktops in the same cluster is acceptable for small-scale and pilot environments to validate the VDI benefits. Dell EMC recommends having dedicated nodes for the management infrastructure and VDI compute within the same or different clusters in the large-scale environment to avoid performance issues.
