TeraBox X5000TT

Multi-FPGA system for high performance computing & network processing

Legacy Product Notice:

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


High performance computing (HPC) and network/packet processing applications demand high-power processing and low-latency I/O. BittWare’s Serial Expansion Chassis delivers both, with up to 4.6 Terabits/sec of I/O and the processing power of up to 8 large FPGAs. A scalable, high-performance FPGA platform, it is a turnkey solution that arrives tested and configured, ready for you to begin developing your application. Connect multiple TeraBox X5000TT expansion chassis to a server, such as BittWare’s TeraBox 4000S, and you can have dozens of FPGAs connected to the same host.

8 FPGAs in a 5U server

Support for BittWare’s full range of FPGA cards

Chassis Key Specs

  • 5U, depth 18in (457mm)
  • Host card: PEU8039 x16 PCIe host card
  • Expansion cable: 128Gb/s, 1 or 3 meters
  • Slots: 8x PCIe Gen3 x16

FPGA Cards

The TeraBox X500TT supports up to eight BittWare PCIe boards. Choose from variety of boards based on the UltraScale+ or Stratix 10 FPGAs. System specs will vary greatly, depending on the FPGA board you select. For example with eight BittWare XUP-P3R PCIe boards, which support up to 512Gbytes of DDR4 per board, the chassis can support as much as 4 Terabytes of memory with 4.9 Terabits/sec of memory bandwidth. With four Stratix 10 boards, each chassis supports 16.8 million logic elements.

Development Support

BittWare offers complete development support for the PCIe boards in the TeraBox X5000TT system. Use BittWare’s BittWorks II Toolkit – a collection of libraries and applications that provides complete hardware and FPGA interfaces – along with BittWare’s FPGA examples for traditional HDL FPGA development. Or use SDAccel or OpenCL for a high-level software-like FPGA development flow.

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.
