Maximum PC

The article Face-To-Face was amazing. However, it opened up a bunch of questions that us geeks would like to know (OK, maybe just me). Just maybe you , Gordon Mah Ung, know and would be willing to tell us on the forum.
The front end servers were running Linux but which one (Red Hat, Solaris, Ubuntu, something else...)?
What database were they running in the back, (DB2, SQL, Oracle…)?
Just how big is the feed into this one data center in Pineville Oregon(OC3)?
Are these servers custom made for FaceBook or can anyone buy them?
What do they do with their antiquated servers? Would they be up for sale?

Please tell!!

hey...
Face to face article is really inspiring.... after reading all questions come in my mind that carry Bill z. i want to know the answers or discussion about these points.....but article is really amazing and has good points......thanks

Agreed - more detail would be great. Also, the article states "For more information on Facebook's datacenter, visit maximumpc.com to see our full write-up." However, I can't find such a write-up anywhere. Can someone please post a link if it exists? If not, can you folks actually do the write-up?

Thanks - we are very interested in this; it's not every day that you get to know about datacenter computing hardware.
