Nallatech 250-SoC – NVMe-over-Fabric (NVME-oF)

The 250-SoC enables the creation of remote, disaggregated storage or Ethernet Just-a-Bunch-of-Flash (EJBOF) to dramatically reduce the storage cost, footprint and power within data centers.

The 250-SoC features a Xilinx Zynq UltraScale+ MPSoC device featuring both FPGA fabric and 64-bit ARM processors. This powerful, feature-rich device coordinates data transfer between two 100GbE network ports, on-board DDR4 memory and a PCIe Gen 4 host interface.

250-SoC FPGA Acceleration Card with Xilinx Zynq UltraScale+ FPGA SoC

This innovative storage product is available either fully-programmable or as a pre-programmed solution featuring Xilinx’s NVMe-over-Fabric IP. This optimized design implements the NVM Express-over-Fabrics protocol offload and RDMA NIC protocol. This turnkey solution provides reliable transport of NVMe frames with low latency, high throughput, and massive scalability to remote hosts.

Notice: Nallatech’s PCIe compliant FPGA boards rely on the host’s cooling capabilities to stay within its acceptable operating temperature limits.

The user must make sure that the FPGA application is designed within the power limits documented by Nallatech and that sufficient cooling is provided to make sure the maximum FPGA die temperature is 15C below the maximum operating limit. Nallatech recommends that users perform a thermal characterization of their application in their system to meet these requirements.
