Network Options
Networking requirements are contingent upon how SolarWinds Failover Engine
is deployed. To deploy as a High Availability (HA) solution, a LAN configuration
is required. To deploy SolarWinds Failover Engine for Disaster Recovery (DR),
a WAN configuration is required. Each network configuration has specific
configuration requirements to ensure proper operation.
Note: SolarWinds recommends that the SolarWinds Channel be configured
on a different subnet than the Principal (Public) network. In the event that this
is not possible, see SWREFID-2528 — Configuring SolarWinds Channel and
Public Connections to use the Same Subnet.
SolarWinds Failover Engine can be configured to run using multiple NICs or a
single NIC.
Multiple NICs
SolarWinds Failover Engine supports use of multiple NICs on each server pair.
When using multiple NICs, one NIC is configured with the Principal (Public) IP
address for client access while a second dedicated NIC is configured with the
SolarWinds Channel IP address. Deploying with multiple NICs provides the
advantage of redundancy and also removes the risk of single point of failure
that exists in single NIC configurations. To configure using multiple NICs on
each server, see Multi-NIC Configuration.
Note: SolarWinds Failover Engine does NOT out-of-the-box support teams of
NICs but can be configured to support teamed NICs with additional configuration
steps when installing with teamed NICs present. See knowledge base article
SWREFID-1947 — How to Install the SolarWinds Failover Engine Packet Filter
Driver on a NIC team (Teamed NICs, NIC Teaming) for more information about
teamed NICs.
Single NIC
SolarWinds Failover Engine also supports use of a single NIC configured to
perform both functions, providing the Principal (Public) IP address to users and
the SolarWinds Channel for data transfer and control. To configure using a
single NIC on each server, see Single NIC Configuration.
Local Area Network (LAN)
When deployed in a LAN environment, SolarWinds Failover Engine requires
that both servers use the same Principal (Public) IP address. Each server also
requires a SolarWinds Channel IP address.
