Agenda
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

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

Native scalable multi-
tenancy
Evolve rather than
replace existing networks
