IT faces challenges supporting laptop users
• Corporate data “walks out of the office”
• Security policies compromised due to personal use
• Backup policies difficult to enforce
• Long recovery times when devices fail
• Personalization leads to support calls
Laptop users need flexibility
IT needs better security & control of corporate laptops
Use Cases
Multiple desktops on a single device
Run multiple roles - each in their own secure operating system
• System admin, test, and user
• Test and development
• Business and personal
• Multiple security domains
• Multi-system demos
• Extending XenDesktop to the last mile of users
• Control for IT, Flexibility for Users
• Fast deployment of new VM’s to employees or contractors
• Self service recovery to any XenClient device
• Secure corporate data
Desktop Virtualization for corporate Laptops
Solution Components
• Type 1 hypervisor: High performance because it runs on bare metal
• Built on 64-bit open source Xen technology
• Runs multiple virtual desktops simultaneously
• Completely secure isolation for each VM
• Hardware independent VMs
• Service VM Architecture for extensibility
What is XenClient technology?
Local VM

X86 Hardware
• Service VMs add shared or unique functionality to Local VM Desktops
• End user interaction
• Advanced security
• VPN connectivity
• Network acceleration
• Built on XenClient API set
• Service VM SDK – coming in 2011

GPU
• SpeedStep • Dynamic CPU clock scaling based on system loads
• Virtual Battery• Reflects physical battery data into the virtual machines
• Sleep• Suspends VM(s) and puts device into S3 state, works on lid close
• Hibernate• Hibernates VM(s) and puts device into S4 state
• Shutdown/Restart• Graceful operation that shuts down running VM(s)

Secure Application Sharing
XenClient Hypervisor
• Execute app in secure VM
• Seamless display in a less secure VM
• Great user experience with total isolation

Synchronizer
Efficient and Robust Data Transfer
• Virtual Disks are VHD files
• Block level differencing using VHD
• Compressed during upload process (client side)
• Left compressed on the backend
• Block level restart on interrupted downloads

Deployment and Backup
• VHD Files Represent Virtual Disks
• Initial Image Delivered from backend
• OS + Apps + Patches
• Mixed in Single VHD Chain
• Updates via ESD Tools
• New changes go into a VHD snapshot
• Backup of snapshots to the datacenter
• Snapshots can be taken while VM is on
• Don’t need to backup initial image
• Background coalescing to merge older snapshots
• VHD snapshots are compressed before sending
