Hi guys,

I`m novice with VoIP and Kerio Operator.
Can you share ideas and real life experience how to setup Kerio Operator in high-available configuration.

We are thinking about VoIP solution and I`m want to be sure that users could be able to communicate if something will happen with hardware (i mean Kerio Operator Appliance 3210).

We bought a spare appliance ((stored offline in the supply room) and we keep regular backups of the config files.

We can cut over within, say, 30 minutes of an outage. I guess we could keep the spare hot in the rack to reduce the cutover time.

Not exactly high-availability, but the parameters have been accepted by management.

Interested to know any other plans/configs folks have.

To be honest, the only real solution for H A would be to setup your Operator in a virtual environment with multiple virtual hosts and redundant SAN.

I agree with Nicholas. A Operator in Virtual environment is only HA solution. Otherwise you must make script that backup after every change to the second Operator. But that means both online and that will give problems.
Kerio Operator can only be Passive/Active placed. So one Active Operator and keep always current backup ready. Passive Operator is powered off and must be update with most latest config backup.

The method I'll be using is with Hyper-V replication. Not true HA, but pretty close to it.

Essentially you have your regular server replicate the VM to a little box. (Micro Server or Mac Mini or something small and cheap).
Then you can run up the VM within a few seconds if you need to, and it's always up to date.

The replication works at the block level so it's pretty much always consistent.
