The BittWare 250-U2 U.2 FPGA Module is energy-efficient, flexible, and intended to be deployed within conventional U.2 NVMe storage arrays. This allows for FPGA-accelerated instances of erasure coding, deduplication, compression, encryption, hashing, string/image search, database sort/join/filter, and machine learning inference.
The 250-U2 can be delivered as a ready-to-run, pre-configured solution featuring Eideticom’s NoLoad® IP, or be programmed by a user developing in-house capabilities. Users can mix and match storage and acceleration on the front-serviceable 250-U2, housed in a 1U chassis permitting integration of storage units in the same server.
