[asterisk-users] Asterisk Redundancy

I agree that better hardware is needed.
I'm looking into buying my own servers and getting a rack in a data centre.
I'll impliment a redundancy solution at the same time.

Thanks for the links.

Get a "Host" that has redundant power supplies.  Was it the power
supply in the server or a phase?

Even an HP DL360 has redundant power supplies, you just yank out the
bad one and put a new one in, no downtime.

If it is power in the building, then maybe you should move your system
to a better "Host" that has different phases and plug your server into
both, via dual power supply, like the DL360.

All of my servers at Equinix are plugged into two different "Power
Sources".

You can also use HA Linux (Heartbeat) in case a box dies.

Thanks,
Steve T
