Stacey,

Alternatively, you could use that system as a "relay only" node (i.e., one that 
doesn't do any local processing) and have other systems connect to it. Each 
could request a subset of the data (e.g., only radar products), and each of 
those systems could file their data. Segregating systems by data-type is a 
common practice.

A time-series plot of I/O activity on the system in question could prove 
enlightening.
