To configure your On-Premise Search nodes for HA, you'll need to add a load balancer and a new service named Ingress Replicator for the Search service.
| Search Component | Nodes Required | Notes |
|---|---|---|
| Ingress Replicator 1 and 2 | 2 separate nodes | It is okay to run an Ingress Replicator on the same host as a Search Broker. The Ingress Replicator journals everything to disk to guarantee all ingressed activities will be delivered at least once. |
| Search Service 1 and 2 | 2 separate nodes | The Ingress Replicators are configured with the host:port of each Search Service. |
