1. Enterprise Data Replication
By Bob Bryar
March 2002 for SearchStorage

2. 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

3. The Data Struggle The Data Explosion The Challenge
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?
The more data a company has, the more it comes to depend on it. Data represents transactions of every kind and it’s behind a company’s ability to serve and satisfy customers. That means that data needs to be instantly available to people anytime, anywhere.
And it means that the systems that store and move the data need to be reliable and available.
Dealing with these issues comes down to a people problem. Where will you find the resources with the expertise to manage your data?

4. Companies are seeking Technological Solutions to many Storage issues!
Backup and Recovery
77%
Capacity
61%
Management

None 5% #1
Companies that are seeking a storage services provider report that they are most apt to outsource their storage in combination with other services. In particular, they are seeking backup and recovery services to protect their data, but also capacity and management services.

14. 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
As a solution, Gartner Group estimates that by the end of next year, a quarter of all corporate IT organizations—across all industries—either will outsource or will consider outsourcing as a solution to their data and content storage 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
