IBM XIV® Storage System: Ease of Management Reinvented
Managing a storage system has become a costly and complicated task. The direct labour cost associated with its management is increasing. In addition, organizations incur hidden indirect costs due to slow responsiveness, ineffective utilization, and inflexibility. This paper discusses how the IBM XIV Storage System's revolutionary built-in virtualization architecture provides a way to drastically reduce the costs of managing storage systems.

Orange- customer case study
The ability to leverage location intelligence was critical to the successful rollout of our 3G network as it enabled us to identify potential customers and where they would likely use our enhanced third generation services. As our decision making process was much more informed by location-based data, we could build our network in areas that will serve our customers most effectively.
