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?

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
