vCenter Server Heartbeat Packet Filter
The network component, installed on all nodes, that controls network visibility.
vCenter Server Heartbeat Pair
Describes the coupling of the Primary and Secondary node in a vCenter Server Heartbeat solution.
vCenter Server Heartbeat Plug-ins
Optional modules installed into a vCenter Server Heartbeat node to provide additional protection for specific
applications.
vCenter Server Heartbeat Failover Process
A process unique to vCenter Server Heartbeat in which the passive node gracefully (manual) or
unexpectedly (automatic) assumes the role of the active node providing application services to connected
clients.
Virtual Private Network (VPN)
A private data network that makes use of the public telecommunication infrastructure, maintaining privacy
