Hot Backup
Hot Backup implements a high availability and rapid recovery solution.
Two RMX’s are configured in a Master/Slave relationship: the Master MCU is active while the
Slave acts as a passive, fully redundant Hot Backup of the Master MCU .
All conferencing activities and configuration changes that do not require a System Reset are
mirrored on the Slave MCU five seconds after they occur on the Master MCU .
In the event of failure of the Master MCU , the Slave MCU transparently becomes active and
assumes the activities and functions with the backed up settings of the failed Master MCU .
In AVC -based conferencing , both dial-in and dial-out participants are automatically dialed
out and reconnected to their conferences. However, the Hot Backup solution is optimized for
dial-out participants as all the dial-out numbers are defined in the system and are available
for redialing.
In
SVC-based conferencing , since dial-out is unavailable, SVC-enabled endpoints will have
to manually reconnect to the conference.
The following entities are automatically backed up and updated on the
Slave MCU :
• Ongoing Conferences
— Layout
—
Video Force
— Participant Status (Muted, Blocked, Suspended)
• Reservations
• Meeting Rooms
• Entry Queues
• SIP Factories
• Gateway Profiles
• IVR services (excluding .wav files)
Queries sent from terminals not listed in the Accept SNMP Packets from These Hosts box are
regarded as a violation of the MCU security, and if the Send Authentication Trap check box is
selected, an appropriate message will be sent to all the terminals listed in the SNMP Properties –
Traps dialog box.
