Cisco Public Local Edition Session Objectives Datacenter 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
