The WSU1 is a mass storage unit that transfers data at rates up to 115 Gb/s. It supplies the SNAP1 acquisition unit with greater storage and record-playback time (about 11 minutes at 115 Gb/s). The two units combine to make a complete 100G 9.8 TB signal recorder, called the EDT WRAP100G.
The WSU1 has four removable WSM1 storage modules, each providing nonvolatile storage of 2.45 TB (9.8 TB total). Each module also provides 60,000 record-erase cycles, via SLC NAND flash memory, at read-write rates of 3.6 GBytes/second (14.4 GB/s total). Four additional WSM1s can be ordered as a WRAP PACK 100G.
To link to the SNAP1, the WSU1 rear panel has three QSFP+ interfaces (one with two 12.5 Gb/s transceivers and two with four 12.5 Gb/s transceivers each, for 125 Gb/s total). The other rear-panel interfaces are four USB, one VGA, and two 1GbE RJ45 connectors.
The system interface (10GbE NIC) uses an SFP+ for optical or a CX4 for electrical signals.
The COTS embedded computer runs CentOS; it has an Intel® Core™ i7 processor and 4 GB of memory.
EDT software is included.
