HeartBeat Redundant Server
Issue 1 July 2006 37
HeartBeat Redundant Server
HeartBeat is a High Availability Linux solution designed to provide servers with hardware
redundancy. HeartBeat provides a primary/hot standby server pairing which can share a single
IP address to the external world. HeartBeat continually checks its partner server over a private
link. In the event of failure, HeartBeat allows the “services” it supports to become active on the
standby server until the primary server recovers.
HeartBeat is used in conjunction with MV_WatchDog, which provides application level
monitoring.
Detailed information on HeartBeat setup is provided in Chapter 9: HeartBeat
. The installation
script provided does all the setup, provided the defaults are acceptable.
Tthe Linux-HA project provides HeartBeat. For more information, see:

Updating Firmware
The Avaya IP Telephone File Server Application server can act in one of 4 modes:
● As an TFTP/FTP/HTTP/HTTPS server, called the basic Avaya IP Telephone File Server
Application server to support the IP telephones.
Note:
Note: TFTP and FTP servers apply only to 4600 Series IP Telephones.
● As a basic Avaya IP Telephone File Server Application server plus as a client to pass data
to a central fileserver.
● As a basic Avaya IP Telephone File Server Application server.
● As both file server and client server.
These various options can be selected within the configuration tools provided.
With the exception of the basic mode, the IP Telephone File Server Application software acts as
either the client or server to provide simple file server firmware download. The IP Telephone File
Server Application uses the HTTPS server for secure transmission using TLS.
Note:
Note: The IP Telephone File Server Application uses RSA, AES256 and SHA security
standards as defaults.
