  2. 2. 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)©2000-2005 IMEX Research All rights Reserved IMEX
  3. 3. 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 “Manage your data before it manages you”©2000-2005 IMEX Research All rights Reserved IMEX
