Dell DVS Simplified Appliance. Desktop Virtualization Solutions Overview A typical Dell DVS Enterprise VDI deployment requires components that are not needed for the typical DVS Simplified Appliance customer. An illustration of a typical DVS Enterprise deployment is shown in Figure 1 and described below: Provisioning Servers: These management servers control the dynamic provisioning and de-allocation of virtual desktops. - Page 13 While this DVS Enterprise VDI architecture is cost-effective for large deployments, it requires a sizable investment that may not be efficient for smaller deployments. Dell configures the solution for customers and provides a thoroughly-tested, well-integrated appliance.
