There are, look better.

I'd suggest to go for a mosaic anyways :-p
Seriously, of course you cannot have a capabilities document with 20 million
entries, that would kill any client.
That many images normally have some sort of structure. Maybe they refer to
different
times or different elevations, but the data is actually always the same in
nature (
e.g., barometric pressure, temperature, and so on).
In such case you should probably give GeoSever 2.2.x a spin and use the
WMS time/elevation support:

Alternatively tiles in a mosaic can be associated with whatever extra
attributes you
want, and those attributes can be used in a CQL_FILTER that will be passed
to
the mosaic to select only the tiles of the mosaic you actually want.
There is little/no documentation on this, but if you look at the mosaic
tests in geotools
you should be able to figure out how to use it (hopefully someone will show
up and
do the grunt work of documenting these abilities)
