Fabric Futures Data centers are quickly making significant
transitions to new technology. This session is designed help you
learn what these transitions are, how Cisco can help you enable
them, and how applications will be the central focus for Data
Center technology in the future. Understand how a spine-leaf
architecture improves data center communications, speeds the
adoption of 10/40/100GB networking, and positions you for the next
great networking technical and management innovation called
Application Centric Infrastructure (ACI). 2
