I would think that some of the physics research facilities like Fermi,
Argonne, Sandia or Los Alamos would have some rather large data
repositories. I've been out of the nuke industry to long. I doubt my "Q"
clearance is any good any more. Cray had many of the computers for these
places but they are being replaced.
I think the NSA probably would kick the CIA's butt on quantity of data.

One of the smaller Physics projects, GLAST (Gamma-ray Large Area Space
Telescope) is looking at storing their data in Oracle. The bulk of thge
data will be a sky map of individual photons, about 20 terabytes, acquired
at a rate of about 1 TB a year. What size is the largest Oracle database at
present? I believe Oracle should be able to handle this, but I'd like to
know if anyone has approached this size. I hear rumors of Oracle databases
of hundreds of terabytes at the CIA, but I have no way to confirm them.

I wrote a little while ago about CERN considering Oracle for LHC project,
and needing a petabyte database. It turns out that the number was
incorrect. The petabyte that was tossed around a few years ago would be for
online and secondary storage only. I don't know their needs for tertiary
storage, but our little project here , called Babar, which is expected to
store half a petabyte of data in online and nearline storage is sized to
300 petabytes when tertiary storage is included. The 0.5 petabytes for
online and nearline will probably be upped. If LHC has the same relationship
between tertiary and online/nearline storage, then they will need something
which can handle about 600 petabytes. Last week I attended a meeting on a
project called SuperBabar. Data estimates of size for that one are one
exabyte. I'm sure there are others in the works which will make SuperBabar
look tiny. The mind boggles.
Babar is not in Oracle and I don't expect SuperBabar will be either.
