In this section, we are going to discuss the sizing of the components previously described in the architecture section. We will start by looking at the management blocks containing the connection servers, security servers, and then the servers that host the desktops before finishing off with the desktops themselves.

The management block and the block hosting the virtual desktop machines should be run on separate infrastructure (ESXi hosts and vCenter Servers); the reason being due to the different workload patterns between servers and desktops and to avoid performance issues. It's also easier to manage, as you can determine what desktops are and what servers are, but more importantly it's also the way in which the products are licensed. With vSphere for desktop that comes with Horizon View, it only entitles you to run workloads that are hosting and managing the virtual desktop infrastructure.
