Enterprise Data Replication By Bob Bryar March 2002 for SearchStorage
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?
