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
