Конференция Brocade. 4. Развитие технологии Brocade VCS, новое поколение коммутаторов VDX6740

  1. 1. Развитие технологии Brocade VCS, новое поколение коммутаторов VDX6740 Vasiliy Soldatov, SrSE vsoldato@brocade.com, Russia&CIS
  2. 2.  VCS Overview  VDX6740&VDX6740T  Licensing  Features NOS 4.0 and NOS 4.1 Agenda
  3. 3. Ethernet Fabrics vs Legacy Networks Automation, Efficiency and Scale on demand  Inflexible: Rigid architecture, optimized for legacy client/server applications  Inefficient: Spanning Tree disables links to prevent loops, limiting network utilization  Complex: Each switch managed individually  VM-ignorant: No concept of server virtualization  Flexible: Topology freedom, optimized for east/west traffic patterns and virtualized applications  Efficient: All links in the fabric are active with Layer 1/2/3 multipathing  Simple: Entire fabric behaves as logical switch  VM-aware: Facilitates VM/network interoperability CLASSIC, HIERARCHICAL ARCHITECTURE CoreAggregationAccess ETHERNET FABRIC ARCHITECTURE EdgeCore Scalability
  4. 4. Key Value Propositions of VCS Fabric  Zero-touch provisioning, configuration, and VM mobility  Self-forming trunks 5x faster to deploy additional network capacity AUTOMATEDAUTOMATED  All links fully active, none on standby  Multi-pathing at all layers of the network: L1/L2/L3 2x greater network utilization AUTOMATEDEFFICIENT  Flexible deployments  Flexible topology  Native scalable multi- tenancy Evolve rather than replace existing networks Built for Cloud
