Figure 1. VMware Horizon on VxRail VMware Horizon clone technology The deployment option for this Dell EMC Ready Solutions for VDI solution supports all cloning techniques available from VMware: full, instant, and linked clones. For the test involving graphics workloads, only one compute node was used with six NVIDIA T4 Tensor Core GPUs configured on that host. One of the hosts was used for both management and compute VMs, and the other three hosts were used only for the compute VMs. For this validation effort, we used a 4-node VxRail cluster.

We validated this solution with the Login VSI and NVIDIA nVector performance tools. For more information about Horizon component design, see the Horizon Reference Architecture available on VMware TechZone. To expand beyond this limit, you can add clusters and balance the VMs and nodes across the new clusters. A vSphere Cluster can have a maximum of 64 nodes and 6,400 VMs per vSAN cluster. Each block has a dedicated vCenter Server and composer servers (if linked clones are used). A block is a collection of one or more resource vSphere clusters hosting pools of desktops or applications. A pod has multiple blocks to provide scalability.

A pod is made up of management servers and a group of interconnected Horizon Connection Servers that broker connections to desktops or published applications. This architecture aligns with the VMware Horizon block and pod design. See the design guide for this solution on the VDI Info Hub for more information about the solution design. The solution runs on the VxRail HCI platform based on VMware vSAN software-defined storage. Figure 1 depicts the architecture of the validated solution, including the network, compute and graphics, management, and storage layers.
