I came across two different architecture for Nexus VPC data center deployment
1. Single Homed
2. Dual Homed
Single Homed
Advantages
Redundant teaming configurations from the servers to the fabric extenders.
Dual Homed
Here we add few disadvantages as well.
Disadvantages
Port configuration should match on both switches (5K FEX)
Complex Design
Out of both designs, i would recommend Single homed Design.
