Objective
Using state of the art technology, IT Executives must execute
tactically against a strategic vision that will provide all Servers
within the corporation, a seamless connection topology to
their most valued corporate resource, data storage
The chosen topology needs to meet several key criteria:
 Return On Investment (ROI)
 Increased Operational Efficiency
 Maintain a High Level of End User Satisfaction
 Meet Business Drivers for Recovery

The Data Struggle
The Data Explosion
 Managing systems diversity
and dispersion of data
 Ensuring the speed and
availability of data
 Ensuring the reliability and
availability of systems
 Ensuring Recovery of Data
is obtainable
The Challenge
Which tools will you
utilize to manage and
protect the data?

Storage Spending Will Surpass
Servers in IT $$
Storage is now a separate, strategic decision

The Data Management Struggle
Gartner estimates that by the end of 2001, 25% of corporate
IT organizations will outsource or consider outsourcing some
aspect of storage infrastructure or management
Outsourcing data
and content storage

Discussions about internal
recovery
 Why can’t we do it ourselves?
 We feel like we’re paying a lot
of money and not getting value!
 I’ve got all the components:

Network

Diverse Centers

Knowledge in High
Availability

Lower Cost of Technology
 What are companies struggling
with?

Change Management

Cost of maintaining dual
environments

Validating the strategy and
capability
