Can the actual backplane prevent you from having larger drives? I understand it can be a performance bottleneck, but drive size prevention?
Absolutely, always has.

So I decided to take the CPU dual x5675 and 96gb ram and put it in my dell r710. with my raid h700 controller.
4tb are detecting.

To clarify, this isn't ALWAYS the case. The backplane can limit drive speed and/or size if it's an expander-type backplane.
On Supermicro, for example, if you have a chassis that ends in "TQ" this means the backplane is not an expander and is merely an input ("direct attached") board allowing SAS connections to it. I.e. you use an SF8087 fanout cable and run the 4 SAS sideband connectors to each port on the board.
Also from Supermicro is the "A" chassis which utilize a breakout backplane which takes a SF8087 input cable and then "breaks out" to 4 connections for 4 drives without modifying the instruction set from your card.
While cabling with both of these become messier than expander backplanes, they're almost forever upgradeable. So whether you bought your 32 drive chassis yesterday or 8 years ago, you can still obtain SAS2 speeds from it and large drives. One can also use a SAS3 card with a SFF8643 to SFF8087 cable, though you will be speed limited to 6Gbps.
