The compute, management, and storage layers are converged into a single VxRail Appliance or vSAN Ready Nodes block, hosting VMware vSphere. vSphere 6.7 supports a maximum of 64 nodes per cluster.
Dell Technologies recommends that you separate the VDI management infrastructure nodes from the compute resources. Because our test environment was small, both management and compute are in the same vSphere HA cluster. Optionally, 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 must be factored in when sizing.
Compute hosts can be used interchangeably for Citrix Virtual Apps hosted applications and desktops, as required.
