just for wish to be impressed: what is vendor of megaservers and what are parameters (like ram, number of processors, type of processors (intel)). If it is not another top secret.

Can't really answer that question because the "Megaserver"is multiple servers networked and coded to work together as one giant server.]

its not just a big unit. It is a technology that allows the data center to place people into instances of the game based on zone population. Other games do this based on an established server population but Zenimax is trying to do this with the ENTIRE population of a Publishing Region. IE one for all of Europe and another for all of North America.

The hardware will probably be the standard Blade Server Array housed in specialized buildings that handle all kinds of IT needs. Some of these facilities are pretty impressive. Punch "Data Center" into google and check it out. I would expect Zenimax is going to lease server space at an existing facility like other mmos do.
