Installation guide

Pre-Installation Checks
A set of system and environmental checks performed as a prerequisite to the
installation of SolarWinds Failover Engine.
Primary
An identity assigned to a server during the SolarWinds Failover Engine
installation process that normally does not change during the life of the server
and usually represents the production server prior to installation of SolarWinds
Failover Engine.
Principal (Public) IP Address
An IP address used by clients to contact the server through drive mappings,
UNC paths, DNS resolved paths, etc. to gain access to the server's services
and resources.
Principal NIC
The network card which hosts the Principal IP address.
Principal (Public) Network
The network used by clients to connect to server applications protected by
SolarWinds Failover Engine.
Protected Application
An application protected by the SolarWinds Failover Engine solution.
Quality of Service (QoS)
An effort to provide different prioritization levels for different types of traffic over
a network. For example, SolarWinds Failover Engine data replication may have
a higher priority than ICMP traffic, as the consequences of interrupting data
replication are more obvious than slowing down ICMP traffic.
Receive Queue
The staging area on a server used to store changes received from another
server in the replication chain before they are applied to the disk/registry on
the passive server.
Remote Desktop Protocol (RDP)
A multi-channel protocol that allows a user to connect to a computer running
Microsoft Terminal Services.
Replication
The generic term given to the process of intercepting changes to data files and
registry keys, transporting the changed data across the channel, and applying
them to the passive server(s) so the servers are maintained in a synchronized
state.
