IBM PureFlex System recommends workload placement based on virtual machine 
compatibility and resource availability. Using built-in virtualization across servers, storage and 
networking, the infrastructure system enables automated scaling of resources and true 
workload mobility. 
IBM PureFlex System undergoes significant testing and experimentation, so it can mitigate IT 
complexity without compromising the flexibility to tune systems to the tasks businesses 
demand. By providing both flexibility and simplicity, IBM PureFlex System can provide 
extraordinary levels of IT control, efficiency and operating agility that enable businesses to 
rapidly deploy IT services at a reduced cost. Moreover, the system is built on decades of 
expertise, enabling deep integration and central management of the comprehensive, 
open-choice infrastructure system and dramatically cutting down on the skills and training 
required for managing and deploying the system.
