Operating Expense Outstripping New Investments

Most organizations will spend $0.50 for power and cooling for every $1 in servers•$29B to be spent on power and cooling

$8 spent in maintenance for $1 spent in new infrastructure

Cost of housing servers is approximately:• $1,000 per sq. ft. or• $2,400 per server or• $40,000 per rack

Why Virtualize?

Server or data center consolidationAverage physical servers utilized only <15%More efficient use of physical assetsPromotes greater centralization and securityReduced capital and operating costs“Green Computing” – less power / cooling

Flexibility - Allow IT agilityDynamically respond to business needsVirtual workloads are mobile and easy to create and manage

Business ContinuityImprove application availabilityKey part of disaster recovery strategy

nominees are running on XenServer

Tesco, the world's third largest retailer, has embraced virtualization to enable the company to drive growth and expansion in new geographies while increasing operational efficiency. By virtualizing its servers to boost performance, Tesco nearly quadrupled the speed of store transactions while cutting power consumption, overhead and carbon emissions and simplifying IT management.

Virtualizing 1,500 physical servers on XenServer, including 80 XenApp servers

Aiming for a conservative 10:1 consolidation

Hitting 70% CPU utilization (up from 6%)

Reducing carbon emissions by 20% (leveraging corporate "greening" budget)
