Need Info for setting up high availability network
 

Is what I have is 7 PIII's I want to setup 2-dns servers, which I have already done, then setup web, mail, ftp, Mysql Database servers, but here is where I get lost: How would it be possible to setup a computer that the other computers go to for data storage, so I can run an automated Controll panel, so I can simply just add more computers for more space as neccessary so I can add unlimited hard drive / Web space ?

My Second Question is: can this be done linking MySql Database servers together Somehow ?

I just do not ever want to run out of hard drive space, and be limited to only how many hard drives I can stick into one computer, if this is possible, could someone atleast point me to a site where I could lern this, or could some one please point me in the right direction ?

Most solutions use clustering and have 2 cluster servers infront of the appliaction/database servers. The 2 cluster servers act as like routers that forward the requests to one of the application servers. The second cluster server will only come into affect should the first one go down.

Allow me to try and simplify my question: What would need to be done to create a way to start out with 1 to 3 servers "Just for storing Data" and be able to just add more computers as necessary "just for storing Data"
as if everything were one big hard drive, and I could just keep adding more space. Why I would need this cluster to be recognized as one hard drive, file, whatever, is explained more the first time I asked this question.

You could do this by just creating nfs shares on each new computer and mounting them on the other computers.

It would seem odd that you wouldn't just upgrade the capacity of the existing servers as this would maintain your resiliency.

You may have your own reasons however.

I can only install so many hard drives on one computer, the fact is that sooner or later I will need to add more space, basically I need endless hard drive space, and I have to make it look to a MySql server that the cluster is just one big hard drive, don't want to have to shut down a network to rebuild it later, I figured all the planning up front would give me a good foundation to start from and something to work towards. I'll look into the NFS. Also does anybody know if one MySql Server can forward a request to another MySql server?

For example, is it possible to have 1 - main Mysql server that would only forward all requests to the appropriate MySql Server?
