Ethernet Recorders

The GDP Model 3500 utilizes mature and field-proven recording technology from Ampex Data Systems Corp. to deliver consistent, reliable recording and playback of streaming IP telemetry data. The Model 3500 has been designed for Telemetry over IP (TMoIP), Voice over IP (VoIP) and Video over IP streaming data recording and reproduction applications. Additional operational modes are available for collecting Ethernet traffic for subsequent analysis by industry standard tools such as “Wireshark”.

Performance and Capacity
The Model 3500 is available in a standard 2U 19 inch rack mount unit. The unit provides two 10 Gigabit Ethernet
interfaces configurable as optical (e.g. 10GBase-SR) or copper (10GBase-T, 10GBase-CX, and capable of autonegotiation down to gigabit Ethernet) plus two 1Gigabit Ethernet interfaces (1000Base-T), as well as expansion capability for 40-GigE, 100-GigE and even WiFi networking. These network interfaces can be configured for Management, Record Data, Playback Data or any combination. The unit leverages reliable COTS solid state drive and server technology with over 70 years of Ampex recording experience and expertise, to meet your challenging requirements. It provides for up to 16 high-capacity, high-performance, removable Solid State Devices, with total capacity up to 32TB today and higher tomorrow as drive technology evolves. The Model 3500 offers raw record and playback performance in excess of 1Gigabyte/second sustained, providing a recording duration of more than eight hours, even at the maximum operational rate.

Open System, Trusted Environments
The Model 3500 is integrated into GDP’s Telemetry Range Management Software (TRMS) control architecture which provides complete range control of acquisition, distribution, recording and processing functions in an intuitive user interface. The system runs an approved COTS operating system, Red Hat Enterprise Linux, to ensure that connectivity with sensitive networks is straightforward and that information assurance and cybersecurity policies are consistent with use in government and aerospace environments. The SSDs support 256 bit AES encryption, and some configurations are available with FIPS 140-2 certification. The system uses components
sourced through U.S. supply chains.

Standards Compliance and Interoperability
In addition to supporting GDP’s enhanced protocols, the Model 3500 also supports the standard IRIG 218 TMoIP, IRIG 106 Chapter 10/11, MISB MPEG-2 Transport Stream over UDP and other streaming data protocols. The Model 3500 is designed to be flexible and versatile. Optional post recording file conversion utilities can be used to provide the data file and output stream conversion necessary to support interoperability with legacy or future systems. The front panel display and keys provide an easy-to-use local interface. Web browser control provides extensive setup, configuration, record and playback control. Integration with the GDP TRMS provides system level integration with other range equipment.
