Multi-channel Gigabit Ethernet data recorder

LONDON — Curtiss-Wright Controls Electronic Systems has introduced the Vortex SDRxE, a fixed-featured off-the-shelf multi-channel Gigabit Ethernet (GbE) streaming data recorder system for demanding sensor-to-processor streaming data applications.

The Vortex SDRxE combines a 3U controller with a reliable, scalable storage subsystem. This rack mountable data recorder can record up to four channels of GbE data at 125MB/s per channel.

The Vortex SDRxE speeds the integration of high-speed data recording and data logging capabilities into subsystems designed for instrumentation recording, mission recording, and SIGINT/ELINT recording applications.

The Vortex SDRxE delivers up to 4 channels of simultaneous GbE data recording and storage. and enables high-volume, continuous streaming recording of GbE data. Other Vortex SDR products support the recording of 10 Gigabit Ethernet (10GbE) and serial FPDP (sFPDP) protocols at line rates, without interruption, from sensors such as radar, sonar, FLIR, RF tuners, MRI, and cameras.

Its flexible storage design enables system integrators to add one or more Vortex SBOD or RAID storage systems as needed for their application's required recording duration. The range of Vortex storage options include a 3U SBOD with 16 fibre channel disks, the compact 2U RAID that houses 12 SATA or SAS disks, and the 4U RAID that supports up to 48 SATA or SAS disks. For extreme applications requiring rugged storage, the Vortex SANbric system supports rotating FC disks.

The Vortex SDRxE supports the special data storage methods required by streaming GbE-based sensor-to-processor applications. Captured GbE data is striped across multiple FC disks in an SBOD to ensure uninterrupted recording. Because Vortex storage technology by-passes the file system it provides total control over data storage and enables high-speed data access via FC from other computers using heterogeneous operating systems.

To simplify control of the Vortex SDRxE recorder, Curtiss-Wright Controls provides the Vortex Graphical User Interface (GUI). This intuitive GUI is fast to learn and easy to setup. After selecting a few parameters, a record or playback session is initiated by simply pressing the corresponding button.

Vortex data recorders feature the uRapidReplay hardware system that enables the SDRxE to capture and time-stamp incoming individual GbE data frames at full GbE line rates prior to storage. This extremely accurate time-stamping enables the precise data playback, via the GbE channels, needed for detailed post analysis.

Time-stamped data is transferred via Fibre Channel (FC) to an external Vortex 3U SBOD(or RAID). With sixteen 450GB FC disks, a single SBOD provides 7.2TB of storage. With four channels of 125GB/s GbE data, the Vortex SDRxE can support nearly 4 hours of recording time. To increase record time only requires the addition of another SBOD. Highly reliable enterprise class, FC disks are d
