TeraBox 4000S

4U Server for FPGA Cards

Obsolete Product Notice:

This is an obsolete product and is not intended for new designs. Contact BittWare for a recommended newer product.


BittWare’s TeraBox-4000S offers a 4U, 8-slot chassis that is ideal for all-around density, CPU power, and yet cost-effectiveness. Configurations include up to 8 of BittWare’s large double-width cards using Achronix Speedster 7t, Intel Stratix 10, or Xilinx Virtex UltraScale+ FPGAs. Users seeking maximum logic/memory density can choose the XUP-VV4 for 30M logic cells and 4TB FPGA-attached DDR4 memory.

Or choose the XUP-VV8, which features QSFP-DDs and yields an impressive 64x 100G — for a port density of 16 per rack unit! No matter which configuration you choose, you’re getting BittWare’s installation and support.

FPGA Cards

The TeraBox 4000S is a 4U FPGA server based on the SuperMicro 4029GP-TRT chassis. This server offers two Intel Xeon Scalable CPUs along with high PCIe slot density. With configurations of up to 8 of BittWare’s large double-width cards, this server is an excellent premium option for the 4U form factor.

System Management

For system management, BittWare’s FPGA cards are equipped with a Board Management Controller (BMC), which accepts IPMI 2.0 commands. Use it along with BittWare’s BittWorks II Toolkit to program the FPGA over USB, monitor card power and temperature, and re-program the onboard clocks. You’ll also be able to set points to shut down the card when it gets too hot, access JTAG, or access the software tools remotely.

The TeraBox Advantage

Choosing a TeraBox FPGA server means knowing you are getting a pre-configured and tested solution. This includes setup and installation of your FPGA cards and associated hardware, your choice of operating system, and development tools. Your TeraBox arrives ready for use—giving your team more time for development and deployment.
