By optimizing efficiency, enterprises can better protect their investments and ensure they achieve a high return on investment (ROI).This renewed focus on efficiency has been partly generated by the tough economic climate over the past few years, with enterprises being more careful in terms of how they spend their money. In addition, a new generation of storage technologies has emerged that make these efficiency enhancements possible.
