2 MAKING VIRTUALIZATION STRATEGIC
Few technologies have taken the enterprise by storm
like virtualization. The concept of decoupling hardware
from software first implemented long ago on main-
frames was reinvented with industry-standard servers.
It has since spread to the network, storage and desktops,
bringing a new level of flexibility and agility to each realm
while providing the foundation for cloud computing.

increase efficiency; what network virtualization is
poised to bring in terms of business agility; and what
benefits all of these technologies deliver to both IT
and the business as a whole.
As we look at the evolution of virtualization, enter-
prises will derive the ultimate promise of what
virtualization can deliver and is already delivering
to some pioneering companies. That s the intriguing
part of virtualization s progression: its move from
being a tactical element for IT to a strategic element
for the enterprise.

How Enterprises Are Taking Advantage
of Virtualization
Here are eight situations where HP customers are already
reaping the benefits of virtualization for specific business
scenarios.
SCENARIO #1 ACCOMMODATE EXPLOSIVE GROWTH:
One of the prime advantages that virtualization brings
organizations is the ability to scale and accommodate
growth. One e-commerce service provider1 recently
experienced startling growth not only in its international
business but in the number of services it offered. What s
more, it faced the prospect of adding 25 percent more
storage every year to accommodate that growth. Instead,
the service provider deployed a completely virtualized
environment, starting with server and storage virtualiza-
tion and moving soon to network virtualization. When
it became apparent during the deployment of a large
enterprise application that 30 percent more storage was
required, the IT department was able to easily fulfill the
request. Virtualization gave them the ability to offer
provisioning of all facets of the deployment in a short
amount of time.

SCENARIO #5 REDUCE OPERATIONAL COSTS: A digital
content company5 needed to reduce server deployment
time in order to better serve its customer base. By consoli-
dating physical server instances onto virtualized servers,
it reduced the number of physical servers by more than
half, from 900 to 400. In doing so, its deployment time went
from one month to a few hours, and it reduced power costs
by 30 percent. From a business standpoint, it is now able to
introduce new services sooner and minimize downtime.

cloud-based mobile device management solutions6 needed
to be able to scale its business to accommodate up to five
million users. It deployed a virtualized server and storage
infrastructure that allows it to support on-demand delivery
