iWarp (RDMA) understanding?

Hey every body.

So I am trying to learn the benefits of iWarp, if any for a client setup.

What I/we wanna accomplish. The client flies and collects multispectral images for agricultur, and they proces these data (stiching images, oberlaying, 3D modeling etc.). As of now they have central storage, where they copy data from, proces the data and put it back. This proces os time consuming. So in an effort to improves their current work flow, we are looking into a new high speed NVME storage, 10gb network and iWarp to try and mitigate the CPU overhead of the network.

So the question. iWarp surely seems smart, in that we can leverage NICs with onboard RDMA chips and iWarp capabilities, and get enhanced latency. BUT. What I am unable to awnser / find, is:

Do the applications they use, need to support iWarp or some thing to be able to benefit from iWarp. It does say that SMB Direct takes care of this, but am I missing something? Anyone have hans-on experience?

Its gonna be between a win 2019 server and win 10 pro workstations.

What i have looked at so fare:
