We’ve been asked to offer a technical proposal for a new established TV station, and the IT manager of the station has a long list of requirements, we covered it all, only one issues lift as we never done it before:

They want about 20-60 GB server for hosting and they want to have a mirror server, incase the 1st server was down, so it would redirect the visitors to the mirror server, I'm thinking of getting them a dedicated or semi-dedicated server, but how do you do the mirror issue.
Some one said to get two dedicated servers, but:
1. How we make it that when one is down, it automatically directed to the other.
2. Should they be from two different companies and to different countries?
3. The web site will be with CMS and DB, how do you make sure that the mirror server have all the new data that was updated in the 1st server’s DB, do they have like shared DB or something, and how..

P.S. We use PHP/ MySql technology.

DISCLAIMER: I work at F5, there are other products that will do this too.

In general:

You setup two web servers and two database servers.
Your application needs to be static on the web server so you can maintain identical servers and use the databases (and replication) to maintain identical backends. I'm not sure how CS would do this since it writes to the local web server disks, you probably need to tweak it to not create user folders, and to store all files, photos, attachments only in the database. I bet the Telligent guys will help for a little cash, they shoudl have a white paper I'm sure Microsoft has it setup this way.
Then you need to handle the traffic redirection. It may be as simple as a DNS setting and TTL which is fucntional, cheap but not very robust. Or, you can use a product like BigIP from F5 http://www.f5.com/products/bigip/ to handle traffic management base don server availability. This is assuming you only want to do a hot spare (redudancy). If you want to use BOTH servers and have redundancy then BigIP will handle the balancing of traffic and redirection if a server goes down.

The real key thing to making this work though is the application and Telligent will have to assist with proper config.
