This is kind of stupid question but at a minimum I thought it would be interesting to know. What is the limitations in terms of swap devices under RELENG_8 (or 9)? A single swap dev appears to be limited to 32GB (there are truncation messages on boot). I am looking at a possible need of 2-20TB (probably more) with as much main memory that is affordable. I am working with large data sets and there are various ways of solving the problem sets but simply letting the processors swap as they work through a given problem is a possible technique. Processors, memory, storage, and other hardware are open issues but for the minute I'm doing things on the cheap, which, admittedly, has a certain intellectual amusement factor. TIA
