• Designed to combine storage capacity from multiple disk systems into a single reservoir of capacity that can be better managed as a business resource and not as separate boxes
• Designed to help increase storage utilization by providing host applications with more flexible access to capacity
• Designed to help improve productivity of storage administrators by enabling management of heterogeneous storage systems using a common interface
• Designed to support improved application availability by insulating host applications from changes to the physical storage infrastructure
• Designed to enable a tiered storage environment in which the cost of storage can be better matched to the value of data
• Designed to support advanced copy services from higher- to lower-cost devices and across storage systems from multiple vendors

Building a more flexible and responsive IT infrastructure

In IT today, the only constant is change. Achieving best business results from a complex enterprise-class IT infrastructure means more than simply deploying new solutions; it means redefining IT as a versatile instrument of business strategy, which can change in parallel with changing demands.
