MeetingPlace server failure
MeetingPlace 8112 and 8106 can handle several critical component failures 
without affecting service. The following table describes the types of 
redundancy features.
Using the shadow server to recover site disaster
One site disaster recovery method is the MeetingPlace Shadow Server. The 
Shadow Server is a backup system that can replace the 8112 or 
8106 conference server in case of system or site failure. Switching over to the 
shadow server ensures that complete MeetingPlace function can be returned 
with minimal loss of time and disruption in service.
For more information about the shadow server, see

Description
N+1 hot swappable 
redundant power supply/
fans
If a power supply fails, the system continues to operate 
with no experienced downtime. In addition, a new 
replacement power supply can be hot swapped 
(inserted while the system is up and running).
Duplicate databases
The server database is stored on two separate disk 
drives (Disk 1 and Disk 2). One is established as the 
primary drive, the other as a backup. Assuming that 
the database on Disk 1 is the active one, the system 
copies all database contents to the database on Disk 2. 
This process occurs in the background, while the 
system is operating. It does not affect system 
performance.
If Disk 1 fails, the system can be restarted using Disk 2 
with the latest copy of the database. If Disk 2 fails, the 
system continues to operate. However, voice files on 
Disk 2 can be lost in this case.
Network backup
It is recommended that network backups be performed 
once each night, in addition to available disaster 
recovery mechanisms. (For more information about 
backing up the database, see

OTE
Before performing a network backup, 
MeetingPlace Network Backup Gateway must be 
installed. See the MeetingPlace Network Backup 
Gateway System Manager’s Guide
