IT Trends
• Compaction• High density computing• Dynamic computer loads• IT / physical infrastructure relationship
The Problem
• More customers reaching power limit• Increased risk of tripping CB• World’s most expensive server• Mostly small data rooms and data centers• Potential impact on Service Providers

Root Cause
• Planning– Capacity - kW– Availability level – N+1– Power density - watts / ft2
• Traditional data center design– Typically built all up front– Built with static power density– Raised floor and perimeter cooling

Proposed Solutions• Change data center specify, design, and build
– Specify the max capacity and availability– Design based on predictable standardized building blocks– Grow in zones – each with its own density and availability
• Rightsize based on your load today• High efficiency components – UPS, VFD Chiller• High voltage distribution• Close coupled cooling• Upgrade utility capacity (source: RSMeans)
– Electrical service > $34,650– Feeder installation > $41,700– Switchgear > $53,280– TOTAL > $129,630
