SolarWinds Failover Engine Diagnostics
The umbrella name for the SolarWinds Failover Engine process and tools used
to verify the production servers health and suitability for the implementation of
a SolarWinds Failover Engine solution.
SolarWinds Failover Engine Heartbeat Packet Filter
The network component, installed on all servers, that controls network visibility.
SolarWinds Failover Engine Pair
Describes the coupling of the primary and secondary server in a SolarWinds
Failover Engine solution.
SolarWinds Failover Engine Plug-ins
Optional modules installed into a SolarWinds Failover Engine server to provide
additional protection for specific applications.
SolarWinds Failover Engine Switchover/Failover Process
A process unique to SolarWinds Failover Engine in which the passive server
gracefully (switchover) or unexpectedly (failover) assumes the role of the active
server providing application services to connected clients.
Split-Brain Avoidance
A unique feature of SolarWinds Failover Engine that prevents a scenario in
which primary and secondary servers attempt to become active at the same
time leading to an active-active rather than an active-passive model.
Split-Brain Syndrome
A situation in which more than one server in SolarWinds Failover Engine Cluster
are operating in the active mode and attempting to service clients, resulting in
the independent application of different data updates to each server.
Subnet
Division of a network into an interconnected but independent segment or domain,
intended to improve performance and security.
Storage Area Network (SAN)
A high-speed special-purpose network or (subnetwork) that interconnects
different kinds of data storage devices with associated data servers on behalf
of a larger network of users.
Switchover
The graceful transfer of control and application service to the passive server.
Synchronize
The internal process of transporting 64KB blocks of changed files or registry
key data, through the SolarWinds Channel, from the active server to the first
