Deep dive why networking must fundamentally change

  1. 1. Why Networking Must Fundamentally Change Larry Hart Head of WW Marketing
  2. 2. The Journey to Efficiency Builds On Virtual Foundation STRATEGIC AGILITY QUALITY OF DATA CENTER SERVICE EFFICIENCY Policy Driven Automation ECONOMIC Dynamic Resource Optimization SAVINGS Rapid Provisioning Disaster Recovery High Availability Server & Storage Consolidation
  3. 3. Why DC Management Must Change Legacy Networks Next Gen DC Networks (Physical) (Virtual) MANAGEMENT CHALLENGES MANAGEMENT SOLUTIONS • Growth means complexity • High performance and scalability built- • Does not scale with virtualization in demands VS • Virtualization-aware components • Cannot keep up with storage growth • Unified Fabric enabling new levels of • Made up of discrete devices storage flexibility • Multitude of management tools • Network building blocks are interactive and scalable TECHNOLOGY CHALLENGES • Data center orchestration • Single Server with Single Application TECHNOLOGY SOLUTIONS • Discrete Communications and Storage •Dynamic Server with Virtual Applications Fabrics VS •Unified Fabrics for Communications and Low Bandwidth in the rack Storage •Lossy QoS •More bandwidth per port •Lots of Ports •“Near” Lossless •Fewer Ports – Higher Bandwidth Fabric convergence, port proliferation, management sprawl & virtualization forcing network management changes. Does that mean your legacy network needs to be thrown out? How do we manage this change?
  4. 4. The Next Step in Efficiency Flexible infrastructure orchestrated through unified infrastructure management Unified Infrastructure Management Compute Storage Networking 4
