The RTR 2757 is capable of capturing these streams in real time at rates as high as 12.5 Gigabytes per second. The rack includes up to 122 TB of NVMe (Non-Volatile Memory Express) storage, using high-performance NVME U.2 drives in a RAID0 configuration to provide extremely high-speed real-time recording. Drives are front-panel removable via eight individual drive trays. The independent operating system drive is also removable via the front panel. This architecture improves the recording speed by fifty percent over previous generations of Talon recorders.
The industrial grade 4U rackmount chassis of the RTR 2757 houses a dual Xeon server class motherboard. It is optimized for cooling and ruggedized to operate in challenging environments. A single QSFP28 optical port supports up to four independent UDP streams for a combined real-time recording rate up to 12.5 GB/s (100 Gigabits/s).
This allows users to stream data from four of the RFSoC's A/D channels over 100 Gigabit Ethernet and capture them as independent files on the recorder. The recorder captures only the Ethernet payload, providing data files similar to other Talon recorders and compatibility with the SystemFlow signal analysis tools. The data format used for storage follows the NTFS standard, allowing users to remove drives from the instrument and read the data using standard Windows-based systems, eliminating the need for file format conversion.
