  2. 2. “Fundamentally we’ve had to redesign and challenge the way we’ve run distributed infrastructure for the past 15 years. Not a single thing that we’ve done in the past is now acceptable for the future.” Steve Hilton, Chief Information Officer, Credit Suisse Group 19-Dec-13 2 © 2013 Brocade Communications Systems, Inc.

  10. 10. Ethernet Fabrics vs. Legacy Networks AUTOMATION, EFFICIENCY AND SCALE ON-DEMAND ETHERNET FABRIC ARCHITECTURE Access Edge Core Aggregation Core CLASSIC, HIERARCHICAL ARCHITECTURE Scalability  Inflexible: Rigid architecture, optimized for legacy client/server applications  Flexible: Topology freedom, optimized for east/west traffic patterns and virtualized applications  Inefficient: Spanning Tree disables links to prevent loops, limiting network utilization  Efficient: All links in the fabric are active with Layer 1/2/3 multipathing  Complex: Each switch managed individually  Simple: Entire fabric behaves as logical switch  VM-ignorant: No concept of server virtualization  VM-aware: Facilitates VM/network interoperability 19-Dec-13 10 © 2012 Brocade Communications Systems, Inc.

  18. 18. Software-Defined Networking: A Taxonomy Gartner Report, March 12th, 2013  “Ending the Confusion About Software-Defined Networking: A Taxonomy”  Defines the two main SDN approaches: 1. “Device-Based SDN Deployment”  Control protocol such as OpenFlow provisions hardware devices PROGRAMMATIC CONTROL 2. “Overlay-Based SDN Deployment”  Use IP tunnels, e.g., VxLAN, NVGRE, or STT, between vSwitches to create logical overlay networks 3/14/2012 19 © 2012 Brocade Communications Systems, Inc.
