Very large swap

[Dennis Glatting]

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
