The Driving Virtualization Trend
• Changing the data center• Better utilization of new/existing
assets• Flexible, available architecture• Shared resource pools to optimize
data center performance• # of servers virtualized
• Changing IT• Deployment..Management..Mature• Creating the virtual infrastructure
Traditional• Single Workload• Low utilization
• 10-15%
Virtualized• Multiple Workloads• Better Utilization
• 60-80%

So what is “Desktop Virtualization?”
• Shared Desktop• Most users per server• No isolation among users• Ex: Citrix Presentation Server (ICA)
Microsoft Terminal Server (RDP)
• PC Blade• Dedicated blade server (1:1 Mapping)• Costly• Ex: ClearCube, HP
• Virtual Desktop• Multiple users per server (isolated)• Versatile• Ex: VMWare (RDP), Citrix, Sun Solaris & Sun VDI

Power Consumption
• Desktop = 120 watts• Laptop = 90 watts • Thin Client = 8 watts• (3) 800 watts servers can run 1000 pc’s
Desktop Management
• 5% under desktop power management policies• Desktop = 1-2 watts• Laptop = less than 1
E-Waste
• 2% of solid waste from IT equipment• 1.63 Million Tons• 12% recycled

In Summary:
• The benefits of implementing Desktop Virtualization:• Cut time, effort, and PC costs• Significantly improve data security• Reduced login time from 30 to 15
seconds• Significant potential energy savings.
ex. 1 tenth the power consumption• More efficient management,
ex: Cut desktop setup time from 1 hour to 10 minutes, centralized
• Significant compliance improvements• Improved SLAs internally and to your
constituents.
