Executive summary
Today we live in a global, 24/7 economy that is pushing the pace of
business to staggering speeds. Forward-thinking leaders of midsize
and large businesses are reevaluating their business models and
looking to technology innovation to provide strategic advantage.
Many businesses are inhibited by their legacy network
infrastructures, which are often proprietary. Their networks are no
longer able to meet current business demands, let alone support
business growth or new technological innovations.
CIOs and network managers are challenged to enable workers to
be mobile, continually connected, and broadly dispersed, and to
interact with one another as well as partners and customers at any
time. At the same time, budgets are constrained, so IT executives
must find ways to increase network capabilities and performance
without increasing costs.
Bringing next-generation technologies into your network enables
you to better meet today’s business demands and put you in a great
position to grasp new opportunities. Businesses can support new
demands and can gain competitive advantage with modern network
infrastructures that are open and based on industry standards.
A modern network infrastructure can also help you reduce the TCO
of your network in a number of ways:
• Modern network infrastructures use open and industry-standard
components, eradicating costly vendor lock-in.
• Modern networking technologies are automated and intelligent,
so your IT staff can dedicate more time to supporting business
growth.
• Network management is centralized, simplified, and streamlined
through a single-pane-of-glass management platform, removing
the need to maintain multiple management platforms.
• Branch office network management is simplified and doesn’t
require dedicated IT staff at remote locations.
If your enterprise is looking for ways to thrive in the new business
world order, read on. We give you five great reasons to modernize
your network now, and we explain how HP, with its advanced
networking technologies, can help you break free from your
legacy network.
Read this paper if you are a CTO, CIO, or IT manager for a midsize or large enterprise interested in
advancing the capabilities, performance, scalability, and security of your network to support
game-changing technologies such as virtualization, cloud computing, mobility, and unified
communications & collaboration (UC&C), as well as lowering the total cost of ownership (TCO) of
your network infrastructure.

4. 4
Help your organization thrive through
mobility and “BYOD.”
As workers use their own digital devices to access corporate
applications, mobility has become the norm. This practice is known
as “bring your own device,” or BYOD.
Consider these IDC top predictions for 2012 and beyond:1
• In 2012, the total unit shipments of smartphones and media
tablets will more than double the unit shipments of PCs. Spending
on these devices now exceeds that for PCs.
• By 2014, the number of “intelligent communicating” devices on
the network will outnumber “traditional computing” devices by
almost 2 to 1.
The mobility explosion has already overtaken the enterprise,
as workers connect to the corporate network with or without
permission. The preferred way to connect will be through WLAN,
rather than lower speed 3G or 4G networks.
Progressive companies will help their workers use these smart
devices to access more than just email and calendaring applications.
Workers must have continual access to their business intelligence,
and companies that develop and encourage the use of customized
mobile applications will keep their employees’ fingers on the pulse
of the business.
The extensive use of mobile devices impacts enterprise networking
in several ways, including an increasing need for secure wireless
access that has sufficient bandwidth and consistent performance
to deliver streaming video and other applications—anytime, in
virtually any location. Businesses must be able to protect both
company- and employee-owned digital devices, while specifying
appropriate network access rules and policies.
Increase business productivity through
unified communications & collaboration.
Companies of all sizes are looking to help workers collaborate more
effectively and efficiently, and to provide customers with more
meaningful interactions. This often creates an explosion in demand
for handling rich media and applications such as streaming video,
large image files, audio, course work materials, video collaboration,
VoIP, and social business solutions. Rather than support individual
applications, it’s much more cost-effective and productive to
implement a single integrated solution for unified communications &
collaboration.
A typical UC&C system has location-aware capabilities that allow
employees to work just about anywhere—in the office, at home, on
the road—using a variety of Internet-enabled devices, including
smartphones, wireless tablets, and of course, desktop and notebook
computers. While implementing a UC&C strategy requires planning,
an investment in new equipment, and considerable setup, the end
result reduces costs for management and communication services
and allows workers to collaborate with ease.
With all of these services now running over your Internet connection
or WAN, you must consider how it impacts latency and quality of
service (QoS). Moreover, workers who are mobile or in a branch office
expect to have the same user experience as their counterparts in the
main office.

5. 5
Support growth and expansion to branch
offices and other locations.
Many midsize and large enterprises are growing, both organically
and through acquisitions. To enhance customer services, businesses
are delivering services closest to the customers. This leads to
numerous branch locations such as remote offices, new storefronts,
warehouses, and factories. If locales were acquired through
acquisitions, there can be a heterogeneous collection of networking
solutions throughout the business. Nevertheless, workers in all
these locations need access to the productivity-enhancing tools in
which the enterprise has invested, and they expect to have a user
experience that is similar to that of the corporate headquarters.
With little to no IT personnel in the branches, corporate IT
organizations must deliver services remotely. What’s more, branch
office networks must be protected by comprehensive security
policies and enforcement to help achieve business continuity.
Modern networking solutions can allow you to roll out a
standardized solution that enables simple, secure access to a full
complement of rich applications with high performance within the
various branch locations and be remotely supported.
Find cost and innovation advantages
through multivendor networks.
Every enterprise has an extensive investment in an existing
networking infrastructure, often with most (if not all) major
components coming from just one vendor. This may no longer be
the best approach to building and maintaining a total network
infrastructure.
According to the Gartner research titled “The Disaggregation of
the Enterprise Network”: “The network infrastructure market has
evolved rapidly during the past three years, from one in which most
organizations adhered to a single-vendor architecture to a more
business-driven network architecture that increasingly uses a
multivendor, best-of-breed approach. Our research found there is
no operational advantage to maintaining a single-vendor approach
(see ‘Debunking the Myth of the Single Vendor Network’).”
Some companies believe that sourcing all components from just one
networking vendor will keep their operations simple, consistent, and
easy to manage. After extensive analysis of hundreds of enterprises,
Gartner analysts conclude that there are benefits to introducing
a second networking vendor, including reducing complexity and
saving budget money:
“Although there is no operational justification for choosing a
single-vendor architecture, we believe that enterprises would
benefit from evaluating the vendors’ operational capabilities,
because there is evidence that different approaches to network
equipment design and operational focus can reduce network
complexity. Those that follow this new approach will find that
they build a better network without functional compromises or
unnecessary overbuilding, while saving substantial amounts
of their total network infrastructure budgets — in most cases,
demonstrating 20 percent to 25 percent total life cycle savings.
Functional and financial analysis has replaced sole-sourcing
convenience, due to the compelling benefits of a disaggregated
approach to network design.”2
In addition, bringing in a second networking vendor will help you
introduce technology innovations that can deliver real business
advantages.

Debunking the Myth of the Single Vendor Network

6. 6
Provide the path to virtualization and
cloud computing for greater flexibility
and agility.
Enterprises are eager to embrace cloud computing because of its
potential for improving agility, cutting costs, and reducing time to
revenue. Through cloud computing, enterprises are transforming
from a service provider role to a service broker. IT organizations
deliver services to end-users that are obtained from a variety of
sources, including public, private or hybrid clouds, outsourcing
providers and managed service providers. To deliver these services,
enterprises often need to consolidate and virtualize data centers, as
well as develop and deploy cloud service solutions to meet the pace
and scaling needs of the business.
The underlying architecture of “the cloud” is a converged
infrastructure in which open and industry standards-based servers,
storage, and networking technologies are preintegrated into a single
computing framework. Additional provisioning and management
technologies are layered on top to provide an entry into cloud
computing.
The network must be agile and flexible so it can effectively obtain
and deliver services from the various aforementioned sources. An
industry standards-based converged infrastructure approach to IT
service delivery helps overcome the complexity, rigidity, and high
cost created by the sprawl of traditional IT. Businesses can reinvest
the savings into innovative and strategic initiatives.
Open networks are the way forward as you look toward the cloud.
Your enterprise needs a network that can easily move applications
and services to the cloud in a seamless, open, and multivendor way.
Characteristics of a modern network
Of course, there are many more than the previous five reasons
to modernize your enterprise network. Mobility, BYOD, UC&C,
virtualization, and cloud computing are driving more application
traffic to the network, and the underlying networks must change
to support them. A legacy network design will eventually reach a
breaking point that will constrain business. Further, enterprises that
don’t segment their network infrastructure could see higher costs
and increased vendor lock-in.
As you reevaluate your network architecture, consider how to
incorporate the following characteristics of a modern network:
• Based on open industry standards
• Scalable in terms of functionality, connectivity, and capacity
• A consistent and pervasive approach to security
• A simplified architecture to increase agility
• A simplified approach to managing the entire network
