Facebook: Yes, We Need 100-GigE

September 16, 2009 | Craig Matsumoto | Comments (13)

It's become cliché to say that companies like Facebook would use 100-Gbit/s
Ethernet right now if they had it. But it helps when someone from Facebook
actually shows up and hammers on that point.

"Hold on there Bald Eagle"

Isn't this a case of every problem being a nail if you only have a hammer?
What is all this bandwidth being USED for?
Surely on the Beowulf list we should be looking at this from the angle of parallel processing -
if your huge central pipe is maxed out, then maybe distributing the problem among many smaller,
cheaper pipes (and processing units) is the way to go.
