Accelerating Your Success ™
2 2

Business Goals of Consolidation
•Server hardware approaching end of life
•Control data center footprint
•Reduce electricity and cooling expense

3 3

Consolidation Impact Assessment
• Considers both the Technical and Financial Impact of Server and
Storage Consolidation
• Uses the VMware Capacity Planner tool
– Non-disruptively captures hardware and software inventory from current
environment
– Measures actual utilization of servers and records the peak workloads
– Uses peak workloads to create consolidation scenario(s)
– Used data collected by VMware from July 19 to September 5, 2008
• Model Financial Impact using Brigham-Gapenski Methodology
– Based on Intermediate Financial Management, 5th Edition (1996)
– Follows the model for evaluating asset replacement “Investment Decisions”
– Provides a familiar analysis for those in finance who support IT
– Develops a Total Cost of Ownership (TCO) baseline of current environment
– Compares the baseline to the TCO of the recommended environment(s)
– Provides a detailed Return On Investment analysis
