The compute, management, and storage layers are converged into a single VxRail appliance or vSAN Ready Nodes block hosting VMware vSphere. The number of nodes that are supported for vSphere 6.7, which is 64, determines the recommended boundaries of an individual vSphere cluster.
Dell Technologies recommends that the VDI management infrastructure nodes be separated from the compute resources. In small environments, both management and compute can be placed in the same vSphere HA cluster. In this scenario, the management node can also be used for VDI VMs with an expected reduction of 30 percent of host resources for these nodes only. The 30 percent reduction accounts for management VM resource reservations and should be factored in when sizing.
Compute hosts can be used interchangeably for Horizon Apps hosted applications and desktops, as required.
