The H700 and H800 are both based on the LSI 2180 chipset:

I'm not sure what's in the H200, but since it does not have a write
cache you don't want one of those anyway.

Note that early versions of these cards shipped such that you could not
use non-Dell drives with them. Customer feedback was so overwhelmingly
negative that last month they announced that the next firmware update
will remove that restriction:

If I were you, I'd tell Dell that you refuse to make your purchase until
that firmware release is actually available, such that your system ships
without that restriction. That's the right thing to do for the
protection of your company, and it sends the right message to their
sales team too: this sort of nonsense only reduces their sales.
