  • Cobra High Speed RecorderCobra High Speed Recorder

    Modular & Flexible

    The Cobra High Speed Recorder is a unique solution for high speed data recording and playback at a rate of up to 20 GB/s (160 Gbps). The system utilizes the PXI Express architecture to provide a modular, flexible solution that can be customized to nearly any requirement. The main recording engine, Cobra, is a PXIe board with high speed RAM and a high performance Xilinx FPGA. This board manages the data movement to and from storage devices and also provides optical fiber channels for high speed data input or output. The Cobra board can be used alone or in concert with additional Cobra boards.

    A typical system configuration will include an Intel processor based controller, one or more Cobra boards, and one or more SSD based storage boards. The PXI Express backplane allows numerous configurations and combinations of storage and recorder boards to match nearly any requirement. Extended systems can also employ an additional chassis to provide additional storage capacity if desired.

    Peer-to-Peer PCI Express

    Conduant’s StreamStor® architecture provides the capability to move data on the PCI Express fabric using Peer-to-Peer techniques. This allows direct hardware data streaming from A/D or other PCI Express sources to or from the data storage without being impaired by system bottlenecks. The system can also accept data from multiple PCI Express sources simultaneously.

    Command/Control

    The Cobra High Speed Recorder can operate independently from a host computer with command/control performed over a network connection. Control can also be automated from a software application using the StreamStor® software API on a network connected computer. A cabled PCI Express option provides connectivity to a host computer for command/control and/or high-speed data access. The cabled PCI Express option provides a 64 Gbps link that can be optionally extended to support long distance links using a PCI Express fiber optic cable.

    Solid State Storage

    The standard storage devices used in the Cobra High Speed Recorder system are M.2 NVMe PCI Express solid state drives. These devices are installed with up to 4 per PXI Express slot using the DM-4M.2 Storage Unit. These drives are available in capacities up to 4 TB each, with even higher capacities expected in the future. The use of solid state drives provides consistent performance even with high levels of shock and vibration. Current standard configurations support up to 128 TB of storage in a 4U 22″ deep chassis. Check with your Conduant sales representative for the latest available storage offerings compatible with the Cobra system.

    High Speed Serial (Optical)

    The Xilinx FPGA on the Cobra board optionally includes up to 24 channels (48 fibers) of high speed optical and can be configured to support many different high speed serial protocols. The protocols possible over these interfaces include ODI (Optical Data Interface), Interlaken, Serial FPDP, and Aurora. Other interfaces can be added according to customer requirements.

    The optical interfaces can also be used to extend the recorder performance. For example, an ODI recorder is capable of 160 Gbps using 4 recorders and a 12 x 14.1 Gbps interface. The optical interface provides a high speed data path that is daisy chained to each recorder so that the speed capability is aggregated across the cooperating recorders.

    The 24 optical fibers can be tailored to customer requirements by bonding channels to create higher speed channels or used independently to record large numbers of slower channels. The Xilinx FPGA also allows Conduant the flexibility to customize an implementation for a particular protocol.

    Trigger/Sync Capability

    The Cobra hardware is connected to the PXI Express backplane instrumentation signals and also has front panel signal connectors. These signal sources can be adapted to customer requirements to provide unique capabilities required for a customer application—triggers, event marking, etc.

    Software API

    The included software development kit (SDK) includes support for .NET development environments. This includes languages such as C#, Visual Basic, and C++ CLI. The SDK also includes a complete “C” based interface to facilitate usage of nearly any programming language. This includes programming environments such as LabVIEW and MATLAB.

    The SDK includes support for features such as wrap mode (circular buffer) for very long duration recording, playback looping, and multiple recording (file) management. Additional features are added regularly and the software can be customized as needed.

     

     

  • The Big River™ DM-4M.2-3U PXI Express storage unit provides up to 15.2 TB of NVME SSD storage in a single PXI Express slot. The DM-4M.2 has a PCI Express Gen3 x8 host interface (up to 8GB/s). With the latest NVME SSD storage, the board delivers high speed data rates for sequential writes of 7.1 GB/s and for sequential reads of 7.1 GB/s in Gen3 PXI Express based systems.

    The single slot design of the DM-4M.2 increases the availability of valuable chassis slots when compared to other solutions and allows for maximum storage flexibility. The DM-4M.2 complies with PCIe Gen3 protocol standards and uses industry standard NVME SSD storage devices. The DM-4M.2 operates under Windows 7, 8.1, and 10, and can utilize the software RAID feature of Windows to combine up to 4 devices on the board into a single addressable device.

    PXIe storage modules offered by Conduant are compatible with all major PXI Express chassis brands, including National Instruments (NI) and Keysight.

  • DM-U.2 removable storage

    The DM-U.2 PXI Express Storage Unit provides up to 7.68TB of removable solid state storage (SSD) in a single PXI Express slot.  It addresses the requirements of users who need to remove and replace PXI Express storage for security or other reasons.  This includes data recording applications where recorded media must be quickly removed and replaced with fresh media between recording missions.   It also facilitates easy data removal for data security reasons when a system is left unattended.

    Each DM-U.2 connects with 4 lanes of PCI Express Gen 3 and supports data rates up to 4GB/s per unit. Performance and storage capacity can be increased by arranging multiple DM-U.2 in a software RAID configuration.

    The DM-U.2 complies with PCIe Gen3 protocol standards and uses industry standard NVM Express (NVMe) SSD storage devices.  NVMe storage devices bypass traditional storage controllers by using a direct to PCI Express connection for the best possible performance. The NVMe drives are compatible with most operating systems including Windows and Linux using standard OS provided drivers. Please contact Conduant sales for information on currently available drive models including capacities and durability.
