Glossary
Active
The functional state or role of a server when it is visible to clients through the
network, running protected applications, and servicing client requests.
Alert
A notification provided by SolarWinds Failover Engine sent to a user or entered
into the system log indicating an exceeded threshold.
Active Directory (AD)
Presents applications with a single, simplified set of interfaces so users can
locate and use directory resources from a variety of networks while bypassing
differences between proprietary services. SolarWinds Failover Engine
switchovers and failovers require no changes to AD resulting in
switchover/failover times typically measured in seconds.
Active–Passive
The coupling of two servers with one server visible to clients on a network and
providing application service while the other server is not visible and not
providing application service to clients.
Active Server Queue
The staging area of the active server used to store intercepted data changes
before being transported across the channel to the passive server.
Advanced Configuration and Power Interface (ACPI)
A specification that dictates how the operating system can interact with the
hardware especially where power saving schemes are used. The primary and
secondary servers must have identical ACPI compliance.
Asynchronous
A process whereby replicated data is applied (written) to the passive server
independently of the active server.
Basic Input/Output System (BIOS)
The program a personal computer's microprocessor uses to get the computer
system started after you turn it on. It also manages data flow between the
computer's operating system and attached devices such as the hard disk, video
adapter, keyboard, mouse, and printer.
Cached Credentials
Locally stored security access credentials used to log into a computer system
when a Domain Controller is not available.
