Visualize Categorise your data Perform clean-up Improve utilisation Virtualize Simplify your storage infrastructure Make open vendor choice a reality Make the infrastructure dynamic Automate Integrate with systems management Workflow automation 3
Virtualisation Simplify the underlying IT infrastructure and its management to help lower cost and complexity while increasing your ability to respond to changing demands Orchestration Storage Infrastructure Management Disk Disk Hierarchical Storage Management Archive Management Storage Virtualization Advanced Copy Services Hardware Infrastructure Tape Recovery Management Storage Networking Content Management 4
Infrastructure Simplification Some terminology Consolidation Leverage advances in storage density to consolidate many older devices into fewer or one newer device. Virtualization Separate the logical representation of a resource from its physical implementation improving flexibility and simplifying management. 5

Improved Application Availability Traditional 1. Stop the application 2. Move data 3. Re-establish host connections 4. Start application Volume Controller 1. Move data Host systems and applications are not affected. Virtual Disk Volume Controller 13
Reduced Cost and Improved Flexibility for Replication Services Traditional Replication service API s differ by vendor, making it difficult to integrate applications Lower-cost disks offer primitive, or no replication services Volume Controller Common replication API, wide, that does not change as storage hardware changes Replication targets can be on lower-cost disks, reducing the overall cost of exploiting replication services FlashCopy Metro Mirror Business Copy Continuous Access Volume Controller SVC IBM DS8000 IBM DS6000 HP EVA HP EVA IBM DS8000 IBM DS4300 FC EMC Sym HP EVA IBM DS4100 S-ATA 14
