  1. Global Delivery of Large Scale VDIwith Quest and Microsoft Daniel BoltonInformation ServicesKingston UniversityMission Statement: To provide a University without walls

  2. About Kingston University • 23,000 Students – 1500 distance learning. • 2500 Staff (excluding temporary staff and guests). • 4 Campuses and multiple satellite offices. • 7000 Desktops (Windows, OS X, Linux). • EST 1000+ Mobile devices (Smart phones, Laptops, Tablets). • Courses run all over the world, China, India, Russia, Greece, etc. • Multiple affiliate institutions.

  3. Business Drivers Original Business Drivers: • To provide “managed” services to mobile and “non-managed” users. • Service delivery for long distance learning students. • Reduce the complexity of the traditional desktop model. • Windows 7 Migration.

  4. Business Drivers Evolved Business Drivers: • Lower the total cost of ownership (where feasible). • Improve service continuity.

  5. Technical Requirements • Location aware – Ability to assign “resources” based on location. • Support for, Windows, Mac and Linux clients. • User environment management. • Integration with Remote Desktop Services (terminal services). • Application Integration – MSI installs, Application Virtualization, etc. • Granular administration – Helpdesk roles, etc. • Connectivity over high latency connections.

  6. Obstacles • User acceptance (at all levels). • Novell lingering on! • IP address allocation. • Applications. • User installed applications. • Identifying the different user types.

  7. User Identification

  8. Our Choice • Quest vWorkspace • Microsoft Hyper-V • Microsoft App-V

  9. Phase 1 – Initial Infrastructure • Designed to support 300 Windows 7 Desktops and 200 RDS sessions. • Utilize existing SAN infrastructure. • Virtual Desktops and RDS servers hosted on Hyper-V (managed by SCVMM). • No Desktop replacements – value added only

  10. Infrastructure

  11. What we are Achieving • Desktops as a Service (DaaS). • Centralised desktop management. • Dynamically assembled desktops.

  12. Dynamically Assembled Desktops

  13. Decisions For Moving Forward • Persistent desktop or non-persistent desktop? • Virtual machine storage, SAN or local disk? • User profiles – folder redirection? Registry capturing? Etc? • Virtualize RDS servers? • Use App-V’s shared cache feature?

  14. Phase 2 – Goals By the end of March 2011 we will (“should”) have the following; • Support for additional 2500 - 3000 virtual Windows 7 desktops. • Support for additional 1500 - 2000 Remote Desktop Services connections. • 300 - 600 Windows 7 RemoteFX “ready” virtual desktops. • Applications streamed using App-V (with shared cache). • Started the next phase of our client hypervisor pilot with vWorkspace integration.

  15. Phase 2 - Infrastructure • 2 Additional vWorkspace connection brokers. • 2 Additional vWorkspace web portals. • An additional vWorkspace user profile server for redundancy. • An additional MS SQL server for fault tolerance vWorkspace DB. • Utilize existing “intelligent” load balancing appliance for web portal connectivity and use to replace the SSL gateway.

  16. Phase 2 - Infrastructure • 50 Additional Hyper-v hosts each with, • 12 CPU Cores • 120GB Memory • 10 146GB 15k SAS drives • 4 Network ports • 1GB GFX card • This gives us (per server), • At least 40 Windows 7 virtual machines with 2GB RAM60 virtual machines was achievable with acceptable performance • 4 – 12 RemoteFX enabled virtual machines • 20 RDS sessions35 sessions with acceptable performance

  17. Infrastructure

  18. Advice • DO NOT RUSH INTO ANYTHING. • ONE SIZE DOES NOT FIT ALL. • IDENTIFY USER REQUIREMENTS. • VIRTUAL DESKTOPS ARE NOT VIRTUAL SERVERS! • YOU DO NOT HAVE TO USE THIN CLIENTS!

  19. Quest and Microsoft • Working with Quest. • Working with Microsoft.
