Automatic Cross-Server File Storage

[wistow]

Hi

I am currently creating a custom image Hosting website and would appreciate your input regarding cross-server file storage. I know these types of sites eat bandwidth and take up lots of storage space, so I was looking at implementing a feature where the site could be run over a few servers instead of just one.

If I decided to go with this option, what would be the easiest way to implement it using php? How would I be able to build it into the admin panel where when a new server is needed, I can just add it into the admin panel and set it up there, and images/files are automatically shared between the servers available so as not to overcrowd any of the servers?

Thanks in advance,

Craig

Make a php script for each additional server that retrieves the memory/cpu/hdd usage. Memory and cpu numbers should be hourly and daily averages. Have the upload script grab each server's stats every couple of minutes. When a user uploads a file have the script find the least bogged down server of the network and upload the file there. You would want to have a php script on each file server to accept files from the main server. I think there is a way to POST files to another server via PHP, but you would have to look into that.
