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
Which tools will you utilize to manage and protect the data?
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

Outsourcing data and content storage
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
15
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 Methodology Effort
