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 notication provided by vCenter Server Heartbeat sent to a user or entered into the system log indicating
an exceeded threshold.
Active Directory (AD)
Presents applications with a single, simplied set of interfaces so users can locate and use directory
resources from a variety of networks while bypassing dierences between proprietary services. vCenter
Server Heartbeat 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.
Advanced Conguration and Power Interface (ACPI)
A specication 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 ow 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.
Channel Drop
An event in which the dedicated communications link between servers fails, often resulting in the passive
server becoming active and consequently creating a split-brain syndrome.
Channel NIC (Network Interface Card)
A dedicated NIC used by the VMware Channel.
Checked
The status reported for user account credential (username/password) validation.
