Terabytes of geotiffs is not a problem, there are properly optimized
installations running off hundreds of terabytes, and some ranging in the
petabytes too,
often the trick is setting up the data properly and do not pretend
sub-second response times if you're trying to make GeoServer open hundreds
of files (optimize
the data so that this is not the case instead).
I believe we need a bit more information, please answer the following basic
questions:
* What OS and GeoServer version are you using?
* Is it a image mosaic?
* Are you routinely trying to display all of the mosaic, or just parts of
it?
* Do you have the tiffs already retiled and with overviews?
This presentation also gives some pointers on how to optimize raster data,
and which data structures
to use depending on your input size:
