[THREDDS #WVA-198552]: NAS Hardware for Thredds Server

Christof,

Most of the buffering is done in memory. This doesn't imply that thredds 
necessarily needs a lot of memory (2 GB can be fine, if a little cramped), 
though more memory always helps. There are a couple processes that do use the 
disk:

1) The TDM, which is a separate daemon you can run for indexing GRIB files, 
writes indexes for GRIB files to disk
2) NCSS, when returning NetCDF4 formatted data, has to first write the data to 
a temporary file on disk. This file is then returned.

I hope this helps.
