ACM Redundancy
5.0A provides a system redundancy feature. Two systems, primary and
secondary, need to be set up and connected through a Dataprobe A\B
switch box. Generally, the primary server is in control of all operations,
while the secondary server keeps a connection with the primary server.
When the primary server goes down, the secondary server should take over
control. The primary and secondary servers must be located in the same
LAN.
In a redundancy system, a keep-alive service serves an important role,
responsible for checking the primary server status and asking the secondary
server to take over when the primary server is down. In the AltiWare
system, AltiBackup is enhanced to provide the keep-alive service.
You can access Redundancy Configuration by selecting Redundancy
from the System Management menu.
Figure 1. Redundancy Configuration
AltiGen recommends that the two systems, primary and secondary, be
EXACTLY identical. All boards, and physical ID, must be in the same
order for redundancy to work.
