Use this design decision list for reference related to the configuration of segments for vRealize Suite components in NSX-T Data Center in an environment with a single or multiple VMware Cloud Foundation instances.

After you set up NSX-T Data Center for the virtual infrastructure, the configuration tasks for most design decisions are automated in VMware Cloud Foundation. You must perform the configuration manually only for a limited number of decisions as noted in the design implication. For full design guidance on the NSX segment configuration, see NSX Segments Design for vRealize Suite Components.

Decision ID

Design Decision

Design Justification

Design Implication

VCF-VRS-NSX-SDN-001

Create one cross-instance NSX segment for the components of a vRealize Suite application that require mobility between VMware Cloud Foundation instances.

Enables potential support for workload mobility without a complex physical network configuration.

The components of the vRealize Suite application must be easily portable between VMware Cloud Foundation instances without requiring reconfiguration.

Each NSX segment requires a unique IP address space.

VCF-VRS-NSX-SDN-002

Create one or more local-instance NSX segments for the components of a vRealize Suite application that are assigned to a specific VMware Cloud Foundation instance.

Enables workload mobility within a VMware Cloud Foundation instance without a complex physical network configuration.

Each NSX segment requires a unique IP address space.

Decision ID

Design Decision

Design Justification

Design Implication

VCF-VRS-NSX-SDN-003

Extend the cross-instance NSX segment to the second VMware Cloud Foundation instance.

Enables workload mobility without a complex physical network configuration.

The components of a vRealize Suite application must be easily portable between VMware Cloud Foundation instances without requiring reconfiguration.

Each NSX segment requires a unique IP address space.

VCF-VRS-NSX-SDN-004

In each VMware Cloud Foundation instance, create additional local-instance NSX segments.

Enables workload mobility within a VMware Cloud Foundation instance without complex physical network configuration.

Each VMware Cloud Foundation instance should have network segments to support workloads which are isolated to that VMware Cloud Foundation instance.

Each NSX segment requires a unique IP address space.

VCF-VRS-NSX-SDN-005

In each VMware Cloud Foundation instance, connect or migrate the local-instance NSX segments to the corresponding local-instance Tier-1 gateway.

Configures local-instance NSX segments at required sites only.

Requires an individual Tier-1 gateway for local-instance segments.
