BittWare 250-SoC Accelerator Card

BittWare 250-SoC Accelerator Card offers a directly attached accelerator and NVMe-over-fabric designed for the creation of remote, disaggregated storage, or Ethernet Just-a-Bunch-of-Flash (EJBOF). The 250-SoC Card reduces the storage cost, footprint, and power within data centers.

The BittWare 250-SoC Accelerator Card includes the Xilinx Zynq UltraScale+ MPSoC device featuring both programmable logic and 64-bit ARM processors. The 250-SoC device is powerful and feature-rich, allowing coordination of data transfers between two 100GbE network ports, on-board DDR4 memory, and a PCIe Gen 3 host interface.
