Yes cellular providers need database that track every call including the ones 
which don't go through.  Internet providers need do do the same.

Event data from physics experiments is stored in file systems developed at 
various high-energy physics sites.

we are creating a system to load 5 billion rows/day that is expected to be 
fully deployed 3rd quarter 2008. 
this is on oracle

Verisign has a custom built database that as of february/march 2007 did 36 
billion executions/day. Its the backend DNS server for the internet. if you go or whatever and its not cached you hit this database. They 
expect it to increase its volume by 20%/year for the indefinite future. it is 
written in C and all data is completely in memory. 

I heard that Google has over 1 petabyte of memory for its search engine. 

There is an particle accelerator being built at CERN in Europe. they are going 
to do an experiment sometime next year that will add 1 GB data/minute or a 
second or something like that. Its a custom made system. The only way I can 
think to do it is with straight serial writes and accept some data loss. Does 
anyone know more about this? 

The absolute highest end systems push the edge of the technology available and 
will always need to be custom built specifically for their task.
