2. Atlantis Computing
Software Company focused on I/O optimization for virtualized environments
HQ in Silicon Valley – Mountain View, CA
Proven technology VC funded by
Strategic Relationships with Key Industry vendors
Industry experts on right-sized VDI deployments
3. Atlantis Addresses VDI Costs and User Acceptance
Software only! – Complement Citrix, Microsoft and VMware
Cuts VDI CAPEX & OPEX – below PC cost!
Use less storage – Over 90% less storage needed
Better performance – x10 more IOPS
Use any storage – Shared SAN/NAS, local disks, or SSDs
Or deploy with NO storage – Any server with ILIO Diskless VDI
Delivers fastest VDI – better than PC, enabling BYOD
Use the same infrastructure for stateless and persistent deployments
Supports Windows XP and Win 7, Server 2008
Mitigate Operational Risks
Address boot storms, provisioning, Win7 IOPs and A/V issues

Windows Characteristics: Storage Considerations:
Average I/O hides a multitude of sins Aggregate and Peak I/O
Small 4K Blocks Boot and Logon Storms
Steady State IOPs profile 80% Write, 20% Read RAID Level = PENALTY!

13. ILIO Diskless
Simplest Design Desktop Density Examples
Eliminates risks in storage sizing and networking Cisco B230 M2 Blade – 160
virtual desktops per blade
No PCI-e cards or SSD’s to install and manage
Chassis (6U) – 1,280 virtual
desktops per chassis
Better Scaling Rack (30U) – 6,400 virtual
desktops per rack
ILIO Fast Clone feature provisions a new desktop within 5
seconds to scale from 100’s of desktops in minutes
Scale upwards or outwards locally or remotely with out storage or
WAN impact on additional storage systems
Simpler Administration
No storage to provision, monitor, or administer Read whitepaper at

15. Virtualizing Citrix XenApp
Virtualisation of XenApp – migration to Server 2008 R2
Increase server utilization
Improve manageability
Upgrade to XenApp 6.5
Virtualizing XenApp → Storage Challenges
Requires SAN/NAS storage
Performance - Provisioning, Boot/Logon time and IO intensive application
Shared storage lowers density
Improper sizing impacts density
