  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 • 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?

  4. 77% 61% 57% 5% Backup and Recovery Capacity Management None Companies are seeking Technological Solutions to many Storage issues! #1 Source: Gartner Dataquest, September 2000

  5. Server Centric Storage Centric Application Server Application Server Application Server File System File System SCSI, FC SCSI, FC JBOD RAID Control File System + RAID Control Evolution of Storage Architectures Network Centric 10/100, GbE, ISCSI

  6. 25% 75% 50% 50% Storage Spending Will Surpass Servers in IT $$ Storage is now a separate, strategic decision Server versus Storage Spending Research from 1999 Server versus Storage Spending projections for 2003 Storage Spending Server Spending “By 2003, servers will become peripheral to storage” Forrester Research

  14. 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. 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 Discussions about internal recovery
