  • Agenda •  Enterprise Workplace and Data Center Networking Trend •  Arista Networks Introduction •  Arista Datacenter Solution •  Arista and Aruba joint SDN Solution
  • Campus Networking Trends •  Wireless will be pervasive with BYOD •  Reduction in wired ports/interfaces •  Major shifts in end point applications •  Cloud drives large file exchanges •  Peer to peer video sharing requires 4-10X increases •  VDI drives low latency, fast interaction with servers •  Authentication, mobility, resource control •  Point to centralized models -> controllers
  • Campus Bandwidth Drivers BYOD AC Access Points Tunneling/SDN 1Gbps Peer-to-peer apps Campus switch Wired and wireless Cloud and VDI Tunneling for access and resource control 10Gbps uplinks
  • Aruba and Arista Aruba delivers the best wireless solution •  Aruba’s leads technically with AP technologies ! •  Aruba offers POE switch line for AP, and wired access! •  SDN is an extension to Aruba’s WLAN controller approach! Arista’s SDN switches - great extension to this design •  Arista leads technically in 10/40/100 Gbps switching! •  Arista offers best power/rack footprint ! •  SDN is an extension to EOS, current and future platforms
