What’s All the Fuss About?


Problem: Success of Scale-out

“OS+app per server” provisioning leads to server sprawl

Server utilization rates <10%

Expensive to maintain, house, power, and cool

Slow to provision, inflexible to change or scale

Poor resilience to failures


Xen Delivers Virtualization Savings

Consolidation: fewer servers slashes CapEx and OpEx

Higher utilization: make the most of existing investments

“Instant on” provisioning: any app on any server, any time

Robustness to failures and“auto-restart” of VMs on failure


Result: Lower CapEx and OpExS

But What About Windows?

Many customers want multi-OS virtualization• Need Windows, legacy Linux, BSD, Solaris…• Ease of use is paramount (install, manage, P2V)• Must integrate with other infrastructure systemseg: storage virtualization, file systems
