Create fewer virtual switches, preferably just one. For each type of network traffic, configure a single portgroup to simplify configuration and monitoring.

Design Decision

Design Justification

Design Implication

SDDC-VI-Net-002

Use vSphere Distributed Switches (VDS).

vSphere Distributed Switches simplify management.

Migration from a VSS to a VDS requires a minimum of two physical NICs to maintain redundancy.

SDDC-VI-Net-003

Use a single VDS per cluster.

Reduces complexity of the network design.

Reduces the size of the fault domain.

Increases the number of vSphere Distributed Switches that must be managed.
