thought you might find this of interest!
Yet, I imagine you probably know about this kinda stuff…
>>>To provide a reference point for the conversation, Rocketboom
currently uses 1 dedicated 100mbs server on Dreamhost to handle the
database and webpages alone and 2 dedicated 100mbs servers on Datagram
to host the videos and the images, for a total of a 300mbit/sec pipe
size. The 2 datagram servers are mirror images (they both hold the
same video and image files) and every single request for a video or
image is alternated like a switch back and forth to each of the two
servers. Our audience number is about 150,000/day of steady flow and
every video now gets over 250,000 downloads (mostly reaching that
number over the course of a few days). Last month we used 12 terabytes
of data transfer on the two Datagram servers and not more than a
Terrabyte on the Dreamhost server (mostly html and xml pages).
