We had a server outage and was asked by our client to "do what it takes to make sure this doesn't happen again. The only solution I can think of would be to have two servers that replicate each other dynamically. The server has a proprietary database application on it, and it running Windows Server 2003.
I'd like some opinions as to what other people do in this situation when they are running mission critical servers and cannot afford to be down at all.
It's a health care environment and runs 24/7, therefore there's never a convenient time to reboot the server, or perform maintenance.
Ultimately it would be nice to test these fault tolerant servers by "unplugging" one and not missing a beat.
Thanks for your help with this...
