These are the supported topologies for stateful services on Tier-0 or Tier-1 in active-active HA mode.
Greenfield Topologies
In new installations, note the following considerations when building one of the supported topologies for stateful services on a
NSX Edge cluster:
- Tier-1 sateful active-active gateways running stateful services must be connected to Tier-0 stateful active-active gateways and must be hosted on the same NSX Edge cluster.
- Tier-1 active-standby gateways can be connected to Tier-0 stateful active-active gateways but Tier-1 gateways must be hosted on a different NSX Edge cluster.
Brownfield Topologies
In existing installations, note the following considerations when building one of the supported topologies for stateful services on a
NSX Edge cluster:
- An existing Tier-1 gateway in active-standby HA mode cannot be configured to be in active-active HA mode. You need to create a new Tier-1 gateway in active-active HA mode.
- Tier-0 active-standby gateways cannot be converted to Tier-0 active-active gateways.
- Tier-1 stateless active-active gateways can be converted to stateful active-active gateways if there no Tier-1 gateways attached to Tier-0 gateways.
Tier-0 Active-Active and Tier-1 Active-Active HA mode
Tier-0 Active-Active and Tier-1 Active-Standby HA mode
Tier-0 Active-Active HA mode (no Tier-1 gateways)
Tier-0 Active-Active and Tier-1 Distributed Router only
