Virtual Desktop Infrastructure (VDI) is centrally-deployed, centrally-managed desktop delivery solution. Various user workloads are packaged together into several flavors of personal or “kiosk” type desktops and are sent to a user via web interface. The VDI stores and runs the desktop, including a Windows client operating system (e.g. Windows 7 or 8), custom software applications, and persistent user data, in a server-based virtual machine in a data center. This allows users to interact with the desktop presented on a user device (traditional workstation, thin client, tablet) via Remote Desktop Protocol.
The following table provides list of required components (hardware, software, licenses and effort) and their estimate cost for deploying 200 concurrent user VDI solution, with 75 Virtual Desktop users and 125 Remote Session Host (previously known as Terminal Services) users accessing the system. End-to-end solution is presented.
The design of this VDI solution is based on best practices published by Microsoft and Dell. The image below presents the major building blocks of the solution, with the network assumed to be existing at the client’s site and thus not included in the estimate.
The described VDI solution adheres to the following principles:
- Concurrent users: 75 concurrent Personal Virtual Desktop Sessions (office local or remote) and 125 concurrent Remote Desktop Sessions / Virtualized Applications (e.g. contractors, field technicians, management and maintenance engineers)
- Easily scalable up with additional building blocks
- Desktops support both Persistent, Personal, Kiosk or mixed modes
- Best practices are followed – Systems and Licensing
- Highly Available – N+1 redundancy in the individual hardware components as well as system overall
- 5 year hardware components warranty
- Cost effective solution
