Introduction
�Virtualization is becoming the IT infrastructure of the
enterprise’s datacenter. This presentation discusses the
advantages of utilizing this infrastructure for WAN
Optimization deployments
�The presentation will discuss the following
o Benefits of virtualization in the Datacenter
o WAN Optimization deployment options in the Datacenter
o Virtualization and WAN Optimization in the remote branch
o VDI and WAN Optimization

The Drive to Virtualization
� Virtualization is being adopted by more and more enterprises as
the datacenter IT infrastructure of choice
� Underutilized servers in the datacenter are consolidated into a
small number of powerful servers as a virtual OS/Application
o Virtualization is endorsed by the new HW technologies (multi-cores,
native virtualization support in CPU, …)
� The adoption rate is expected to grow:
o Forrester: 66% of the Enterprises will use virtualization by 2009
o IDC: 50% of the physical servers will be virtualized by 2011
o Gartner: by 2015 every aspect of IT will be virtualized

Top Reasons for Virtualization
�Physical Server Consolidation
o Efficient HW utilization
� The 80/ 20 rule
o Density and space
o Power and cooling savings
�Greener IT
o Reduce the carbon footprint
o Use of energy efficient servers
�Storage Consolidation
o Cost efficient solutions
o Easier backups and DR

Top Reasons for Virtualization contd.
� IT
o Smaller IT team
o High Availability, Backups and DR
o Ease of management and control
o Rapid deployment
o Minimal Downtime
o OS Licensing
�And more…
o Legacy support
o Testing
o Scalability

Traditional WAN Optimization in the DC
�WAN Optimization has become an essential part of the WAN infrastructure in the Enterprise
�WAN Optimization deployment in the Datacenter (unlike the remote branch) can pose multiple challenges to the IT organization:
o Medium to large enterprises will require multiple high end appliances in the datacenter - complexity, space, power
o High Availability - backup and DR is complex
o Manageability - monitoring and control
o Scalability - complexity of deployment

Virtual WAN Optimization in the DC
� By leveraging the existing virtual infrastructure in the Datacenter, WAN
Optimization can be deployed as a virtual service or appliance
� A Virtual WAN Optimization solution will provide the same benefits as the
classic one and will get all the benefits of the virtual deployment
o IT Standardization – using the same management and configuration tools in the
Datacenter as the other virtual applications / servers
o Easy to deploy using standard virtualization tools
o Scalable – allows utilization of the best of breed HW, add more as you grow…
o Greener WAN Optimization – power, cooling
� In the future, with the introduction of stronger router blades and switch
blades for the enterprise, we expect to see WAN Optimization running on
the blade as a virtual service with additional services

Virtual WAN Optimization in the DC (cont.)
�Additional benefits:
o Density awareness
o Reuse of the Datacenter’s shared storage (NAS, SAN, …)
� Same backup and DR tools can be used
o Support for high availability based on Virtualization
capabilities
o Flexible and dynamic licensing models for Virtual WAN
Optimization Services (VWOS)
o Cost effective – a SW only solution

Virtual WAN Optimization in the DC (cont.)
�Virtual WAN Optimization considerations:
o Requires an existing virtual infrastructure
o May require additional virtualization licenses
o Supports only ON-LAN (off-path) network deployment
� Not a real issue in the large datacenter
o Requires the right resource allocation
� CPU, Memory, disk space
o Sizing and performance planning
� Difficult to benchmark and to size

Virtualization in the Remote Branch Office
�Virtualization can be used in remote branch offices as a means of deploying WAN Optimization
�WAN Optimization can be installed on the existing server infrastructure in the RBO as a virtual service
�Main benefits:
o Leveraging existing physical infrastructure (space, energy, manageability)
o Deployment in environments where appliance can not be installed (Airplanes, Ships, Hostile environments, etc.)
o Extremely Cost effective (virtualization license is free)

Physical Desktop Consolidation
� Physical desktop consolidation replaces existing desktops in the remote
branch with thin clients running via a remotely accessed Operating
System and Applications
� Virtual Desktop Infrastructure (VDI) is the technical foundation utilized to
deploy desktop consolidation projects
� Using VDI, remote users connect to the datacenter and attain a Virtual
Desktop (Windows XP, Vista, Linux) running enterprise applications
� WAN Optimization solutions for VDI (must be supported) can be deployed
over the virtual infrastructure in the datacenter, allowing a tighter
integration into the environment
Expand Networks Confidential and Proprietary
Virtual Desktop Infrastructure (VDI)
� Thin Client
o HW platform which runs the virtual desktop
� Connection Broker
o Manages connections and resourcesfrom branch to the Data Center
� Virtualized Machines (Remote OS)
o Typically XP, Vista or Linux running over a virtualization layer
� Virtualization Server(s)
o Virtualization servers run virtualization OSes
� Management Console
o Configuration, alerts, statistics and monitoring
Expand Networks Confidential and Proprietary
Conclusion
� WAN Optimization can be deployed as a virtual solution over the existing virtualization infrastructure in the Datacenter
o IT benefits (standardization, HA, backup & DR, configuration & management, flexibility & scalability)
o Cost effective
� The same virtual solution can be applied in the remote branch
o Leverage the physical servers, cost effective
o Deployment flexibility in challenging environments
� Virtualization support goes hand in hand with VDI
o Tighter integration into the Virtual Desktop Infrastructure
� Virtualization support is available (as a controlled release) by Expand Networks
o General Availability is planned for Q3/2008
