 VDX6740&VDX6740T
 Licensing
 Features NOS 4.0 and NOS 4.1
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

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

• Interoperable with legacy STP
deployments (Redundant Links)
• Supports STP, RSTP, PVST+, MSTP
• Entire VCS appears as a single switch
the STP topology
• No loss of bandwidth inside Fabric
• High utilization for E-W Traffic, loop
prevention for N-S traffic
