VMware, Inc. 87
A Active
The functional state or role of a server visible through the network by clients running protected
applications and servicing client requests.
Alert
A notification 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 among proprietary services. vCenter
Server Heartbeat switchovers and failovers require no changes to AD, resulting in switchover and failover
times measured in seconds.
Active – Passive
The coupling of two servers: one server visible to clients on a network and providing application service,
the other server not visible and not providing application service.
Active Server Queue
The staging area of the active server used to store intercepted data changes before being transported
across the VMware Channel to the passive server.
Advanced Configuration and Power Interface (ACPI)
A specification that dictates how the operating system can interact with hardware using power saving
schemes. Primary and Secondary servers must have the same ACPI compliance.
Asynchronous
A process whereby replicated data is applied (written) to the passive server independently of the active
server.
B Basic Input/Output System (BIOS)
The program a personal computer's microprocessor uses to start the computer system 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.
C Cached Credentials
Locally stored security access credentials used to log in to a computer system when a Domain Controller
is not available.
Channel Drop
An event in which the dedicated communications link between the Primary and Secondary server fails,
often resulting in the passive server becoming active and consequently creating a split-brain syndrome.
