2 Businesses are facing data migration and mobility challenges Business change and ongoing requirements magnify challenges in managing IT infrastructures - Business cannot be disrupted - Pressure on planned downtime Migration is difficult and complex - Highly specialized skills - Lack of predictable results during migration - Disparate tools and processes - Proprietary technology Mobility and management are obstacles to IT and business flexibility - Data alignment and movement have become the gating operations - Platform and multivendor choices are limited Clients are looking for greater flexibility when selecting solutions, to reduce risk and complexity associated with managing and moving data Migration challenges 41 percent of firms move data at least monthly or weekly 1 82 percent of firms report they experience problems when moving data 2 48 percent of firms rate coordinating outage time with users as the number-one pain point involving migration 3 61 percent of migrations exceeded originally planned downtime 1 36 percent of migrations experience data loss 2 29 percent of firms delay storage purchases due to migration issues 2 Manual data mobility is the number-three highest challenge for implementing tiered storage 3 1. ESG, Data migration everyone is doing it but are they doing it right?, March Softek Migration Study, N = 550, February TheInfoPro, TheInfoPro Storage Study Wave 8, F1000 sample, N = 131, October 13, 2006.

3 Why data is moved? 25% Operational and infrastructure 22% Storage equipment replacement 10% Relocation 16% Server equipment replacement 17% Consolidation 10% End of storage lease 48% migrate for technology refresh 25% migrate for operational and infrastructure reasons 17% migrate for consolidation 10% migrate for relocation Chart source: ESG, Data migration, 700 end users, March 2005.

4 Enterprise data migration: different shapes and sizes Technology refresh Server/storage consolidation Direct attached storage (DAS) to storage area network (SAN) Old array Data migration New array Data migration Data migration SAN Facilitate tiered storage Data migration Improve performance Data migration

5 Moving data presents risks and costs Can you afford these risks and costs? Percentage of end users who experienced problems during data migrations 64% Unexpected downtime Risks 38% Application performance issues 38% Data corruption 34% Missed data or data loss % Excessive staff time Costs 54% Budget overage 51% Technical compatibility issues *Chart source: ESG, Data migration, March 2005.

6 Softek TDMF software can solve migration challenges What is Softek TDMF (Transparent Data Migration Facility) software? - Since 1996, Softek TDMF software has been the industry gold standard for migrating data while providing continuous application availability (Nonstop Data Mobility ) - Softek TDMF host-based software performs nondisruptive data migrations in enterprise environments Why Softek TDMF software? - Provides freedom to move data at your convenience Across vendors storage devices Over distances On leading platforms At virtually any time - Nondisruptive to applications - Enables array and server upgrades - Supports 24x7x365 business continuity and high-availability goals - Helps simplify data migration management
