How do I take advantage of RDMA in windows


How can I copy blocks of memory from one server to another under windows using RDMA? We don't have infiniband, but we do have 10gb network switches. All I need is an example, but I'm not having much luck with google.

EDIT:

Well no one has answered my question so far. I just need a link to an example, or the name of a few functions. Everything I have read so far seems to be in the driver SDK or in sockets. I want to use RDMA in our software to update local copies of data from a main server. The data is up to 10GB in size. Most of the time the updates are about 1GB, but if a server has to reboot, the entire compressed dataset is 10GB. I want to update some of the data nearly continuously and RDMA seems to be the route to take.


Solution

  • You need NetworkDirect API. There's no documentation whatsoever on how to write something using NetworkDirect, only the interface description. The closest thing to the documentation that I could find is starting from here, and then going deeper into every link. But you can check the ND tests source code for the usage examples.
