Fidus Systems based the design of its Sidewinder-100 PCIe NVMe Storage Controller on a Xilinx Zynq UltraScale+ MPSoC ZU19EG for many reasons but among the most important are PCIe Gen3/4 capability; high-speed, bulletproof SerDes for the board’s two 100Gbps-capable QSFP optical network cages; vast I/O flexibility inherent in Xilinx All Programmable devices to control DDR SDRAM, to drive the two SFF-8643 Mini SAS connectors for off-board SSDs, etc.; and the immense processing capabilities that come from the six on-chip ARM processor cores (four 64-bit ARM Cortex-A53 MPcore processors and two 32-bit ARM Cortex-R5 MPCore processors); and the big chunk of on-chip programmable logic based on the Xilinx UltraScale architecture. The same attributes that made the Zynq UltraScale+ MPSoC a good foundation for a high-performance NVMe controller like the Sidewinder-100 also make the board an excellent development target for a truly wide variety of hardware designs—just about anything you might imagine.
The Sidewinder-100’s significant performance advantage over SCSI and SAS storage arrays comes from its use of NVMe Over Fabrics technology reduce storage transaction latencies. In addition, there are two on-board M.2 connectors available for docking NVMe SSD cards. The board also accepts two DDR4 SO-DIMMs that are independently connected to the Zynq UltraScale+ MPSoC’s PS (processing system) and PL (programmable logic). That independent connection allows the PS-connected DDR4 SO-DIMM to operate at 1866Mtransfers/sec and the PL-connected DDR4 SO-DIMM to operate at 2133Mtransfers/sec.
All of this makes for a great PCIe Gen4 development platform, as you can see from this photo:

Because Fidus is a design house, it had general-purpose uses in mind for the Sidewinder-100 PCIe NVMe Storage Controller from the start. The board makes an excellent, ready-to-go development platform for any sort of high-performance PCIe Gen 3 or Gen4 development and Fidus would be happy to help you develop something else using this platform.
Oh, and one more thing. Tucked onto the bottom of the Sidewinder-100 PCIe NVMe Storage Controller Web page is this interesting PCIe Power and Loopback Adapter:
Fidus PCIe Power and Loopback Adapter
It’s just the thing you’ll need to bring up a PCIe card on the bench without a motherboard. After all, PCIe Gen4 motherboards are scarce at the moment and this adapter looks like it should cost a lot less than a motherboard with a big, power-hungry processor on board. Just look at that tiny dc power connector to operate the adapter!
