should be fine for Trilinos and deal.II.

That shouldn't be a problem for storing matrices and vectors, and I suspect also not for the iterative solvers. I'm not sure the direct solvers in Trilinos can handle that, though. That should be relatively simple to find out with a little test program, though.
