The compute, management, and storage layers are converged into a block of vSAN Ready Nodes, hosting VMware vSphere. Sixty-four nodes are supported for vSphere 7.0—that number determines the recommended boundaries of an individual vSphere cluster.
Dell Technologies recommends that you separate the VDI management infrastructure nodes from the compute resources. In smaller environments, 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 accounts for management VM resource reservations and should be factored in for sizing. Compute hosts can be used interchangeably for Citrix Virtual Apps hosted applications and desktops, as required.
