Storage and Availability Objectives
Manage storage growth
• Improve operations• Reduce cost per GB• Utilize existing assets
Increase availability and DR readiness
• What isn’t Mission Critical?• Maintenance windows shrinking• Site consolidation & A-A DR
Reduce cost with new technology
• Server virtualization• x86 servers• Thin storage
