New Normality The CIO’s Balancing Act – Optimize, Grow, Comply
Rapid Growth of Smart Mobile Devices
In 2011, twice as many ‘smart’ mobile devices will ship than laptop devices
These ‘connected’ devices will drive an explosion in social interactions, mobile transactions and digital content creation
Server and network infrastructure will be needed to support resulting edge, application and database workloads
Collaborative, Web and Security Infrastructure will be particularly important
Unit Shipments (Millions)
Smart Devices Grow 4x
Explosive IP Traffic Growth
is Stressing the Current Network Infrastructure
…BUT THE EDGE OF THE MODERN NETWORK IS UNDERGOING ITS OWN
TRANSFORMATION AS WELL
DATA CENTERS HAVE BECOME THE CORNERSTONE OF BUSINESS…

Video, and more, video:
Impact on the enterprise network
Video and related applications will legitimately proliferate
Telepresence becomes more mainstream
Video-survellience and other streaming apps, many vertical-specific, will
be increasingly deployed
Web video has cast its net with enterprise video collaboration apps
(training, marketing)
IT will react to this video explosion
Throw more bandwidth at the problem- good news for infrastructure
vendors
Pressure will increase for vendors to roll out 40/100G sooner rather than
later
Improved compression technologies will be rolled out, but that won’t solve
the problem either

Network Journey
Today’s Network
• Global scale
• Reliable
• High Performance
Meeting DatacenterDemands
• Enabling Consolidation
• Real Time
• Bandwidth optimization
What’s Needed Tomorrow
• Orchestrating Virtualization
• Bringing Business value to IT
• Flexible and dynamic
Key CIO Initiatives- Networking
Need to reduce/optimize IT resources in a touch
economic environment
Support for new emerging applications (VoIP,
Video, WLAN)
Improved manageability across the network and
remote sites
Launching new virtualization services
Scalable infrastructure that can grow to support
- increased traffic
- new sites
- new services
Data Center Drivers & Requirements
• Reduce TCO
• Find means to simplifying the
network
– Cost effective aggregation
– Investment protection for 10 GbE
• Offer best in class services, need to
control costs but deliver high
availability
• Quickly scale to meet demand, roll
out new services
• High availability—always on
• Pay as you grow for capacity and
density
• Ultra high capacity, predictable
performance under load
• End-to-end solution
• Some degree of automation

Datacenter Network Attributes
Note: N=155
Q. When evaluating various Datacenter networking products, please rate the following attributes using a 7 point scale where 7 is
extremely important, 4 is somewhat important, and 1 is not at all important
% of respondents rated important and extremely important

It’s ALL IMPORTANT!
Cloud Will Shape Network Requirements
• Opportunity will reach $1.4 billion in
2011
– Prevailing IT trend of the decade
– Public, private and hybrid models
will emerge
– Industries will migrate at different
rates
Benefits include:
– Reduced TCO
– Dynamic response
– Better allocation of resources
Source: IDC 2011
Evolving Datacenter Networks:
Public, Private or Hybrid?
Q: How does the appeal of private clouds in your organization compare
with that of using public cloud services?
Source: IDC Enterprise Panel – 4Q09, n = 240
Hybrid Environments
• Majority of customers prefer private clouds
• 65% more find private clouds more appealing
• Network needs to support both private internal cloud and hybrid environments
• Infrastructure changes become a natural outcome
Expected Private Cloud Benefits
Virtualization and the Network:
Best Practices Emerge
• Network managers evaluating best
practices
– Default build for IT
– Cloud service providers early
users
– Place in network will dictate
success
– UC apps coming on board
Benefits include:
– Faster time to deploy
– Advantages with application
development

Evolving Virtualized Datacenter Network
“Flatter” Networks• Network simplicity brings
additional cost savings
– Less devices, line cards, power
• Fabric management is a must!-optimize and control bandwidth/services levels to virtual machines
• Agility to achieve virtual machine migration--cloud
• Foundation to automation

Most Important Factor in Enterprise Customers'
Decision for a Campus/HQ LAN/WLAN
Source: IDC Enterprise Networks Survey, 2010
Campus LAN: Refresh Drivers
– More bandwidth, scalability in network infrastructure• Growth of enterprise data and multi-media traffic
• 100Mb to 1GbE, 1GbE to 10gbE Upgrade
• Only 31% IT managers expect network to meet performance requirements in next 12 months*
• Energy Efficiency
– Need for PoE and PoE+• Driven largely by VoIP and 802.11n WLAN Upgrades
– Move to “Flatter” Networks• Network simplicity brings operational cost savings
– Virtualization and the Datacenter• Server Aggregation
• Converged infrastructures

Campus LAN/WAN Attributes
Note: N=135
% of respondents rated important and extremely important
Source: Enterprise Communications Infrastructure Survey, IDC, March, 2010
– Closest to end customer
– Strategic opportunity for IT to
bring business value
– Increased demand for real- time
access to data• Focus on users and transactions
• Business analytics
• Network-centric applications
Remote Branch Network
1/3 will increase the number of branch offices
1/4 of IT budget associated with branch
1/2 will invest in network changes
– Work at home• Branch of one
– Globalization• Enter new markets
• Expansion of customer base
• Seeking competitive advantages
– Collaboration• Leverage employee talent globally
• Communicate with partners and suppliers globally

Emerging Mobile Architectures
Revenge of the consumer- With the rapid
growth of smartphones and tablets, 2011 will
bring a different level of legitimacy to mobility in
the enterprise
Variants of centrally managed Wireless LANs
continue to proliferate:
Direct Forwarding, Controller-based
Centralized vs. Distributed Control, Controller-
less
The differentiation still mostly around how to
handle the control and the management plane
2011 will bring focus, and pressure on
operators, vendors and enterprises to finally
resolve in-building coverage issues

The Role of The Network in Efficiency
1. Voice and video
2. Network based business
3. Intelligent networks are
winning over dumb pipes
4. End point growth
5. Cloud Computing, SaaS and Virtualization
– Today is the New Normal
• Enterprises are investing in the network to jump ahead of competition
• They are open to new ways of deploying the network including virtual network services.
• They are ready to rethink the network; take costs out & increase flexibility
– The dynamics around “Virtual, Mobile, Social” require a new way of rethinking the network
– Architect your network for tomorrows needs
• An intelligent, secure network that excels in application performance
– Cloud will Drive Change on the Network
• Unified Fabric is becoming a reality
• 40/100G is coming- the drivers are there
• WAN is still complex and needs to be an enabler
• Takes costs out and increase flexibility
