  • Storage Optimization: Storage optimization efforts continued in 2009 with a goal of continuous improvement in the levels of consolidation and savings that can be achieved. New disk arrays with higher densities and multiple tiers of storage were used to consolidate onto fewer, more cost-effective, disk arrays. FAST technology was adopted to automate the movement of information between tiers of storage for optimal performance and cost efficiency. Enterprise Flash Drives (EFD) were tested with performance sensitive Oracle and SQL database applications.
