In this paper, we first show you how to configure a PVRDMA device in a vSphere environment, including the ESXi host setup, VM setup, and guest operating system setup. We then demonstrate the performance benefits of PVRDMA over TCP and show close performance to RDMA-capable hardware used in passthrough mode, all while supporting vSphere HA, DRS, and vMotion.
