Agenda

 Strategic Storage Plan
 Managing Hurdles (Knowledge, Budget, Management)
 Data Protection
 Issues (Existing Techniques/Pains)
 Techniques (Mirroring, Snapshots, Replication, CDP)
 Lowering TCO
 Tiered Storage (Aligning Cost of Stg. w Value of Data)
 Standardization/Interchangeability (Investment Protect,Virtualize)
 Autonomics (Lights Out Management)
 Futures
 Information Classification & Mgmt (Reference Metadata Engines)

Data Storage Hurdles
 Budget Mandates
 CEOs Mandate for CIOs: Do more for less
 Migrate to Nex-Gen Infrastructure while protecting existing IT investments
 Justify ROI/TCO (Acquisition + Operating Expenses)

 Knowledge of Emerging Technologies
 Keeping pace with new technologies, products, standards & management
 Avoiding Pain Points - Backing up whole files, despite very little changed
 Full restores when only a few bytes need to be put back
 Management
• Managing Hodge-podgy growth and complexity
 Standardizing on few configurations to reduce complexity
 Establishing Data protection, Business Continuance/Disaster Recovery
 ILM/Regulatory Compliance
 Implementing Virtualization, Provisioning & Lights-out Storage Automation
