VMware Virtualization: The Foundation for a Green Datacenter

2 Agenda The Datacenter Climate Crisis Prioritizing Green Datacenter Initiatives Laying a Foundation for Efficiency Continuous Rightsizing of IT Infrastructure VMware’s Economic and Environmental Impact VMware Customer Successes

3 Market Perspective Datacenters becoming exponentially more dense Datacenter refresh driven by power/cooling/space Energy cost is consuming more budget and is harder to ignore The divide between IT and facilities is narrowing Environmental impact, govt awareness and corporate initiatives on the rise kW per Rack Cost to Power Server Will Soon Exceed Purchase Price

4 Today’s Model is Broken Poor forecasting + low flexibility = excess capacity Typical datacenter: 3 years excess server capacity Servers consume >50% of average power when idle Datacenters are outdated and hugely inefficient Cooling servers often requires 2x the power consumed Over-provisioned Capacity Inefficient Datacenter Design

5 Datacenter Spend is on the Rise Source: McKinsey & Co.

6 Power Consumption in the Datacenter Computer Rm. AC 34% Server/Storage 50% Conversion 7% Network 7% Lighting 2% Source: APC Where Does the Power Go? Compute resources and particularly servers are at the heart of a complex, evolving system!
