Hot Backup

19-98
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.
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.
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)
• Recording Link
• Profiles
• IP Network Settings:
— H.323 settings
— SIP settings
— DNS settings
— Fix Ports (TCP, UDP) settings
— QoS settings
