Building on Kontron's successful VX305x and VX305C-40G SBCs, and designed in alignment with the SOSA™ Technical Standard,the VX305H-40G 3U OpenVPX Single Board Computer leverages the VITA 65 (OpenVPX) SLT3-PAY-1F1U1S1S1U1U2F1H-14.6.11 Payload, or Compute Intensive slot profile adopted by both SOSA™ and the US Army CMOSS Modular Open Systems Architecture programs to bring processing and network performance to 3U systems. Using the highly integrated 12-core Intel® Xeon® D processor, the VX305H-40G complements the 40 Gigabit Ethernet Data Plane (40GBASE-KR4) with a second 10 Gigabit Ethernet Data Plane (10GBASE-KR), a 10 Gigabit Control lane (also 10GBASE-KR), and a wide 8-lane PCI Express 3.0 expansion plane. It also provides an XMC site with an 8-lane PCIe Gen3 interface for adding capabilities such as front-panel I/O or large block storage. As a result, it is a SWaP-C optimized computing platform suitable for a wide range of applications. The ITAR-free VX305H-40G is an ideal choice when designing a high-performance sensor system using modular open systems architecture principals.
VX305H-40G brings server class applications into the battlefield
Typical programs are :
Rugged By Design
The high-performance VX305H-40G is available in both air-cooled (for lab or other benign deployed environments) and conduction-cooled Plug-in units as per VITA 48.2 Type 2, Secondary Side Retainer. This enables the VX305H-40G to sustain 70°C card edge temperature according to VITA 47 XMC support. The VX305H-40G is also available with a VITA 48 Ruggedized Enhanced Design Implementation (REDI) Two-Level Maintenance bottom cover option.
Additional Features and Advantages
System health and maintenance is a key differentiator of the VX305H-40G. Provided by the combination of a Kontron-designed VITA 46.11 compatible Intelligent Platform Management Controller (IPMC) for centralized system health and management, and Kontron's Power-On Built-In Test (PBIT) package with its innovative “Reference Learn” approach, the VX305H-40G brings a new level of system health and management capabilities to rugged deployed systems. These built-in features can be augmented by Kontron's CMON Linux Health Monitoring Engine, which creates a continuous flow of health data from customizable test points
for either remote or local monitoring.
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 VX305H-40G an ideal candidate for long term programs.
