NTRDMA v0.1 - An Open Source RDMA Driver for PCIe NTB and DMA

NTRDMA is a new open source Remote DMA (RDMA) driver for PCI express (PCIe) Non-Transparent Bridge (NTB) and general purpose Direct Memory Access (DMA) hardware. A common technique in enterprise storage arrays is to use an internal PCI express bus to connect peers in the system. While system providers such as EMC Corporation have long supported transferring data across the NTB interconnect, the functionality has only ever been supported by proprietary software, tightly integrated hardware drivers and applications, and specific products. With the development new open market hardware platforms featuring NTB, and the release of the NTRDMA open source driver by EMC, this allows for wider adoption of NTB as an RDMA transport.
