Dell PERC 5/i "does" have an option to create multiple LUNs.
So, i have been quite moronic in not trying to apply logic initially.
As for now, i am creating a small "system" disk,
and multiple 500G "data" disks.

I do not really need to have 1 big partition for the data.

So this is a lot simpler setup i believe,
and no chance of hitting the 2T limit.

A big thanks to everyone who guided me, and my apologies if this 
qualifies as a "waste of time" post.

This, for sure, is the best list i have ever experienced.

Thank you all again.
