Plug-in
An optional module that can be installed into a vCenter Server Heartbeat server to provide additional
protection for a specific application.
Pre-Installation Checks
A list of system and environmental checks performed before the installation of vCenter Server Heartbeat.
Principal IP address
An IP address used by clients to contact the server through drive mappings, UNC paths, DNS resolved
paths, to access the server's services and resources.
Principal NIC
The network card that hosts the Principal IP address.
Protected Application
An application protected by vCenter Server Heartbeat.
Q Quality of Service (QoS)
An effort to provide different prioritization levels for different types of traffic over a network. For
example, vCenter Server Heartbeat data replication can have a greater priority than ICMP traffic, as the
consequences of interrupting data replication are more obvious than slowing down ICMP traffic.
R Remote Desktop Protocol (RDP)
This multi-channel protocol connects 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 VMware Channel, and applying them to the passive server so both servers
are maintained in a synchronized state.
Role
The functional state of the server in the pair that can be either active or passive.
Rule
A set of actions vCenter Server Heartbeat to perform when defined conditions are met.
S Security Identifier (SID)
A unique alphanumeric character string that identifies each operating system and each user in a network
of Windows NT, Windows Server 2000, Windows Server 2003, and Windows Server 2008 systems.
Server Monitoring
Monitoring the active server by the passive server, using a heartbeat message, to ensure that the active
server is functional.
Server Pair
The generic term used to describe the coupling of the Primary and Secondary server in vCenter Server
Heartbeat.
Shared Nothing
A key vCenter Server Heartbeat feature whereby hardware is not shared between the Primary and
Secondary servers, thus preventing a single point of failure.
SMTP
A TCP/IP protocol used in sending and receiving e-mail between or among servers.
