Video Location when using 2 servers

If I have 2 servers, 1 for Dolphin website and the other for media server.  When a user uploads a video and its processed, etc. is the video located on the media server or still on the Apache server hosting the dolphin site?

Assuming the media server does not store videos or pictures than I it would not need much space?

Thanks

if using dolphin upload feature for videos, the videos are stored in your website at /public_html/flash/modules/video/files

Okay that makes sense, I have a few more questions pertaining to this topic.

In a 2 server scenario as explained,one server has apache, website, and modules on one server and andother  dedicated media server.

Since uploaded vidoes will reside on the web server how is bandwith consumed?  For example a member views a Video that was uploaded and some members are viewing this video.  Does the members make connections to the streaming server?  I thought the concept is the members stream from the media server however if the video file is on the web server how does that work?

I need to know what server is sending bandwith at what point so I can properly scale my servers and services.  Is there a diagram or some information regarding this?

Thanks

it is not necessary, i dont think, to run 2 physical servers. In my scenario, I have one dedicated server. In which I run both my webserver and my RMS. 5 years and counting and never had any issues with bandwidth.

The RMS is used mostly for streaming use. So when the video chat is in use then your using the media server bandwidth.

For things that don't require the RMS server such as normal videos and sounds then they are served up by your webserver.

So it depends on what is being used.
