Remote Direct Memory Access (RDMA)

The New Wave DV Fibre Channel Remote Direct Memory Access (FC-RDMA) core provides a complete layer 4 hardware IP solution for the FC-RDMA protocol.

The core provides full FC compliance, hardware-based LUN mapping, and complete offload of RDMA frame handling including: FCP Data IU offload, hardware Command IU Response, DMA controller, frame building/checking, and CRC generation/checking.

The host interface to the core can be AXI or PCIe. The core is built for dropping into a FPGA and providing the complete design from processor interface to FC-RDMA network interface.

This core is targeted towards applications in aerospace and has been used on a wide range of parts at varying operating rates. The core comes with test-benches and example code, making design integration a straightforward task.

Evaluation versions of the FC-RDMA IP core are available and New Wave DV has a set of standard form-factor boards featuring FPGAs, Fibre Channel optics, and off-the-shelf reference designs for quick evaluation of the IP core.
