3U VPX Intel® Xeon® Processor Single Board Computer
Mouseover Zoom loading...
  • 12-Core 1.5 GHz (2.1 GHz Turbo)
  • Ideal for Virtual Machines and HPEC Applications
  • Extended Life Cycle and 10-year Silicon Reliability
  • Dual 10 Gigabit Ethernet, x8 PCI Express Gen3 Bandwidth
  • Up to 32GB soldered DDR4 with ECC
  • Air-Cooled and Rugged Conduction-Cooled versions

Building on Kontron's successful VX3058, the VX305C 3U VPX Single Board Computer uses the highly integrated 12-core Intel® Xeon® D process, supporting Dual 10 Gigabit Ethernet, high bandwidth PCI Express 3.0, and high speed DDR4 memory. As a result, it is SWaP-C optimized with versatile mezzanine options for XMC, storage, graphics, M.2, and I/O. Combined with Kontron's advanced switch technologies and centralized health management, VX305C is a logical choice for both high thread count and high performance embedded computing applications.

VX305C brings server class applications into the battlefield

Typical programs include:

  • Radar, sonar
  • Imaging systems
  • Airborne fighter and UAV sensors
  • Long term programs in harsh environments

VX305C and leading edge architecture for Multi-CPU computing nodes

VX305C provides two 10 GBASE-KR ports and 8 lanes Gen3 PCI Express to the backplane. A 10 Gigabit Ethernet switch and a PCI Express Switch can be complemented with two respective single star data planes. Kontron’s sample turnkey system StarVX implements this architecture, enabling a significantly higher I/O bandwidth. While computing power has been continuously increasing in the past, and I/O bandwidth did not, the balance of both is back again by Kontron StarVX. VX305C makes it a powerful, leading edge Multi-CPU computing node architecture.

Long term programs: high reliability and low Total-Cost-of-Ownership

Kontron provides a Long Term Supply program service (LTS) for over 15 years. Intel communicates silicon reliability is 10 years. A comprehensive Health Management is optionally available to support easy field maintenance. All this makes the VX305C an ideal candidate for long term programs.
