Glossary
H Hardware Agnostic
A key vCenter Server Heartbeat feature enabling the use of servers from different manufacturers, models,
and processing power in a single vCenter Server Heartbeat server pair.
Heartbeat
The packet of information issued by the passive server across the VMware Channel, which the active
server responds to, indicating its presence.
Heartbeat Diagnostics
The umbrella name for the VMware process and tools used to check the production server health and
applicability to the implementation of the vCenter Server Heartbeat solution.
High Availability (HA)
Keeping users seamlessly connected to their applications, regardless of the nature of a failure. LAN
environments are ideally suited for HA.
Hotfix
A single, cumulative package that includes one or more files used to address a problem in a product.
I Identical Nodes
The use of two servers identical in name, IP address, and security identifier (SID).
Identity
The reference of a server’s position in the server pair based upon hardware, either the Primary server or
the Secondary server.
L Low Bandwidth Module (LBM)
A vCenter Server Heartbeat Module that compresses and optimizes data replicated between a Primary
and Secondary server, thereby delivering maximum data throughput and improving application
response time on congested WAN links.
M Machine Name
The Windows or NETBIOS name of a computer.
Management IP Address
An additionally assigned unfiltered IP address used for server management purposes only.
Many-to-One
One physical Secondary server (hosting more than one virtual server) can provide protection to multiple
physical Primary servers.
N Network Monitoring
Monitoring the active server’s capability to communicate with the rest of the network by polling defined
nodes around the network at regular intervals.
Non-Identical Nodes
Two servers in a cluster using differing names and Management IP addresses.
P Passive
The functional state or role of a server that is not delivering service to clients and is hidden from the rest
of the network.
Passive Server Queue
The staging area on the passive server used to store changes received from the active server before they
are applied to the passive server’s disk or registry.
