The Fabric40 Advantage: Next-Generation 40Gbps Technology, Enhances Interoperability While Reducing Integration Risk and Development Time

Fabric40 logo

Curtiss-Wright’s innovative Fabric40 initiative ensures that all aspects of 40Gbps data fabric technology are optimally configured to work together, enhancing interoperability and reducing customer integration risks and development time. We take the risk out of extreme OpenVPX Gen3 signaling.

Fabric40 is the industry’s first complete end-to-end system approach for integrating the latest Gen3 high-speed 40 Gbps fabrics into a new generation of radar processing, SIGINT, image processing and Electronic Warfare systems that cannot afford to compromise on performance.

Curtiss-Wright implements this technology with a broad range of complementary Fabric40 modules, delivering over 2x the performance of previous generation SRIO Gen-2-based systems and 4x the performance of 10 GbE-based systems. The Fabric40 family of modules includes the CHAMP-AV9 DSP engine, the VPX6-6802 Switch, and the VPX6-1958 single board computer (SBC), as well as Virtex-7 FPGA processing with the CHAMP-WB-DRFM and CHAMP-FX4.

Atrenne Computing Solutions, a Fabric40 Ecosystem Partner, delivers Gen3 Fabric40 OpenVPX backplanes that support full-speed, bottleneck-free distribution of data over 40Gbps Ethernet, PCIe Gen3 or InfiniBand fabrics.

These modules and backplanes enable the design of a new class of embedded subsystems capable of delivering previously unobtainable levels of performance. Fabric40 solutions reduce both risk and development schedules for the most demanding defense and aerospace applications.

Five Fabric40 Characteristics

1. Reduces Signal Integrity Risks

All Fabric40 products have been developed with highly optimized signal integrity design rules to ensure that high-speed signals are not compromised when interconnects are operating at Gen3 speeds.  

2. Fabric Agnostic

Fabric40 allows system integrators to build optimally configured HPEC systems using the latest high-speed fabrics. Fabric40 supports Ethernet, PCIe Gen3 and InfiniBand protocols with data rates up to 40Gbps to ensure your processing nodes are not starved, waiting for data. Ethernet is supported using industry standard 10G and 40G interconnects, and InfiniBand supports data rates of SDR (10G), DDR (20G) and both QDR and FDR-10 (40G). PCIe Gen3 supports 8G full duplex transmission per lane.

3. Supports RDMA

Fabric40 drivers are optimally configured to take advantage of these high-speed rates. To ensure that processing engines and CPUs are not burdened by high-speed data transfers, all Fabric40 modules support Remote Direct Memory Access (RDMA) in both GbE and InfiniBand modes.

4. Middleware Ties it all Together

The Fabric40 ecosystem also includes middleware software enablement such as IPC and OFED/MPI interfaces, which are highly optimized to support next-generation 40 Gbps systems. These software interfaces provide a high level abstraction of fabrics, operating systems, and even processors, shielding your application from vendor and implementation-specific details, enhancing portability and meeting MOSA requirements.

5. End-to-End Solutions

Fabric40 system elements from Curtiss-Wright and ecosystem partners such as Atrenne provide a complete system solution, including SBCs, DSP and FPGA engines, GPGPU processors, network switches, chassis and backplanes.   You can be confident that your entire next-generation system will work together reliably from end-to-end.
