•
Server Protection – provides continuous availability to end users through
a hardware failure scenario or operating system crash. Additionally,
SolarWinds Failover Engine protects the network identity of the production
server, ensuring users are provided with a replica server on the failure of
the production server.
•
Network Protection – proactively monitors the network by polling up to three
nodes to ensure that the active server is visible on the network.
•
Application Protection – maintains the application environment ensuring
that applications and services stay alive on the network.
•
Performance Protection – monitors system performance attributes to ensure
that the system administrator is notified of problems and can take
pre-emptive action to prevent an outage.
•
Data Protection – intercepts all data written by users and applications, and
maintains a copy of this data on the passive server which can be used in
the event of a failure.
SolarWinds Failover Engine provides all five protection levels continuously,
ensuring all facets of the user environment are maintained at all times, and that
the Public network continues to operate through as many failure scenarios as
possible.
Communications
SolarWinds Failover Engine communications consist of two crucial components,
the SolarWinds Channel and the Principal (Public) network.
To accommodate communications requirements, SolarWinds Failover Engine
can be configured to use either multiple NICs (1 X Channel and 1 X Principal
(Public) connection) on each server providing a separate dedicated SolarWinds
Channel network from the Principal (Public) network or a single NIC on each
server to fulfill both the SolarWinds Channel and Principal (Public) network
connection requirements.
