  1. 1. Virtual Desktop Infrastructure (VDI) Centralise the Desktop Cam Merrett Demonstrator
  2. 2. Virtual Desktop Infrastructure Virtualisation Connection Brokers PC/Thin Client/Lockdown PC Remote office options Security Considerations TCO Savings What is VDI?
  3. 3. The Physical World Data security and compliance are at risk. One-off fixes are costly. Desktop refresh is complicated and slow. Applications conflict and impact performance.
  4. 4. The Virtual World Centrally control, track and secure data. Centrally fix and deliver patches globally at a lower cost. Rapidly update PCs or operating systems. Isolate applications to improve performance and speed.
  5. 5. Virtualisation Layer Hypervisor- Example • Runs directly on hardware • Manages resource allocations • Strong fault and security isolation • Encapsulation • Highly scalable architecture • What’s available • vSphere • Microsoft Hyper V • Xen Server

  12. 12. VDI Connection Broker  Generally a Windows Server VM(s)  Web Server component  Datastore containing VDI pool information  Authenticates against Active Directory  Communicates with VM Management Services  Passes Connection details back to User
  13. 13. Benefits Desktop costs  Purchase price £399  Maintenance £140  Half day to install £105 ◦ £35 per hour  Admin – 15 hours £525  Power usage £240  Total £1,409  Per annum £352.25 VDI Costs  Thin client £240  Maintenance £0  One hour to install £35 ◦ £35 per hour  Admin £0  Power usage £20  Back Office £265,000 £530  Total £825  Per annum £206.25 Cost per user model (500 users) 40.3% saving – payback 16 months
  14. 14. Real-World Financial Examples
  15. 15. What made VDI produce such high savings Storage was the most expensive part of VDI and priced the solution higher than PC’s. Thin provisioning from Citrix, VMware or Netapp has cut storage costs by 80%
  16. 16. Additional Incentives/Benefits  Green Computing Initiative  Needs of a mobilised workforce  HA/DR for Desktop estate  Hardware Independence  Smooth the transition to Windows 7
  17. 17. Power Savings with Client Consolidation Client Consolidation uses much less power than traditional desktop deployments ◦ e.g. Assume 200 users  Traditional desktop power consumption: ◦ 200 users X avg 300 watts per PC = 60,000 watts  Client Consolidation power consumption: ◦ 3 x3850 = 6,000 watts + DS4700 = 1,000 watts + 200 Thin Clients x 5 watts = 7,000 + 1,000 = 8,000 watts  Cost savings is 260 watts per desktop ◦Estimated savings of £80 per PC per year! ◦ (assumes 10 pence per KW hour price for electricity).
  18. 18. Security Considerations Secure Client device – End Point security Connection to data centre - SSL VPN / Firewall Secure virtual desktop – Hypervisor AV
  19. 19.  No real physical savings for laptop users - Yet  Laptops can be replicated to backup virtual machine  Laptop sometimes not needed (e.g. office to office)  User can work from any location  The Future : ◦ Client Hypervisor with Secure Partition ◦ Online and Offline Access ◦ Bare metal Performance ◦ Synchronization Laptops
  20. 20. VDI and Remote Office Connectivity & Performance Business Result: - No IT staff at remote locations - High speed access - Data is protected - “single instance of data” - Less hardware, licenses, storage, tape - None or less servers for branch office services - Data is safe!! SAN LAN Data Centre WAN Wide Area Network Core Edge Edge
  21. 21. Very first phase of deciding on VDI Discovery Tool Kit Collect detailed information on current estate OS versions and patch levels, CPU make, model, speed, Physical memory size Age of device Total number of displays and maximum resolution Total number of local disks, total capacity of storage available, total amount of storage utilized Local printers USB devices and peripherals (connected at scan) Applications deployed • The installed applications discovered on the end point, Application usage • The average and maximum memory used by each discovered application • The peak and average CPU usage of each discovered application Local storage usage – the amount of disk space broken down by application
