Curtiss-Wright's new scalable, multi-channel serial FPDP-based streaming data recorder captures, stores, and retrieves data at 245MB/s per channel
The SDRxR is a high-performance record and playback data recorder system designed for demanding sensor-to-processor streaming data applications.
This turn-key system, consisting of a single 3U rack mounted chassis containing the controller, the interface boards, and the hard disk drives for two channels, delivers multi-channel recording of high volume, continuous data streams at rates up to 245MB/s per channel for intensive data applications such as radar, sonar, Flir, RF tuners, and MRI.
This scalable Cots-based data recorder simplifies and lowers the cost of accurate high volume data recording.
The SDRxR, the latest addition to Curtiss-Wright's innovative SDRxL family of streaming data recorders, represents a breakthrough in easing the high-speed capture and retrieval of large quantities of data.
Each SDRxR system comes standard with twelve 300Gbyte fibre channel (FC) hard drives that provide up to 3.6terabytes of disk storage that support up to four hours of recording time per 245MB/s SFPDP channel.
The SDRxR's storage capacity is scalable to virtually any size required.
It supports one, two, or multiple SFPDP channels through the interconnection of multiple 3U controller units which can be operated as a single system.
"Curtiss-Wright's SDRxR streaming data recorder raises the bar for cost-effective, high performance streaming data storage," said Gorky Chin, vice president and general manager of Curtiss-Wright Controls Embedded Computing's Dayton group.
"As the inventor of SFPDP, the Dayton group is the market's leading expert in bringing high speed, scalable data capture to the Cots market.
"The proliferation of sensor data across application types demands an affordable, scalable approach for accurate capture, archival and retrieving of mass amounts of streaming data.
"The SDRxR simplifies this increasingly urgent task".
Streaming data recording.
A single SDRxR controller records one or two channels of streaming SFPDP data at rates up to 245MB/s per channel.
Recording time is approximately four hours per channel when the system is configured with twelve 300GB drives.
The SDRxR uses a unique method of striping multi-channel, high volume data across multiple FC disks to enable uninterrupted recording.
The SDRxR bypasses the host processor's file system to provide total control over data storage.
Archived data retrieval.
Because file system attributes are not embedded with the streaming data, users can access the data at FC rates from heterogeneous PCs.
Archived data can also be retrieved via the SDRxR's gigabit ethernet port at rates up to 1.25Gb/s.
RapidReplay for data playback.
The SDRxR's RapidReplay operator control GUI provides a simple to learn and use VCR-style control interface.
The GUI runs on a customer provided Windows XP/2000-based PC.
Software support.
The SDRxR provides an API for use with embedded systems.
The API runs on Windows XP/2000 and Linux operating environments.
A command line interface (CLI) is also provided with the standard system.
The CLI can be used from a 'terminal' application to directly control record and playback functions.
CLI commands may also be embedded in a user script file using Perl, TCL, or other scripting languages.
