Failover
XProtect Management Server Failover
If a standalone computer running the Management Server service or the SQL Server has a hardware failure, it
does not affect recordings or the recording server. However, these hardware failures can result in downtime
for operators and administrators who have not logged in to the clients.
XProtect Management Server Failover provides high availability and disaster recovery for the management
server. If the management server becomes unavailable on one computer, the other computer takes over
running the system components. In cases of hardware failure, the secure real-time replication of the SQL
database contents ensures that there is no data loss.
XProtect Management Server Failover can help you mitigate system downtime. You can benefit from a failover
cluster when:
l
A server fails – you can run the Management Server service and SQL Server from another computer
while you resolve the problems.
l
You need to apply system updates and security patches – applying security patches on a standalone
management server can be time-consuming, resulting in extended periods of downtime. When you
have a failover cluster, you can apply system updates and security patches with minimal downtime.
l
You need seamless connection – users get continuous access to live and playback video, and to the
system’s configuration at all times.
You configure XProtect Management Server Failover between two computers. To make the failover work, the
following system components must run on each computer:
l
Management Server service
l
Event Server service
l
Log Server service
l
SQL Server
Failover management server (explained)
Failover support on the management server is achieved by installing the management server in a Microsoft
Windows Cluster. The cluster will then ensure that another server take over the management server function
should the first server fail.
