[asterisk-users] Redundancy / Failover

[Noah Miller]

Hi Norman -

>> To add to what Edgar said, yes, use linux-ha.  It works nicely in
>> combination with DRBD.  DRBD uses a dedicated network interface on
>> each box with a crossover cable between the two.  It does a block
>> level copy of the entire filesystem, so you have two machines that are
>> identical.  The you use the linux-ha heartbeat to monitor the OS and
>> asterisk.  If anything goes wrong, it can fail over to the second
>> machine.
