For many COTS [commercial off-the-shelf] vendors and VITA members, the Tri-Service Memo issued in January 2019 by the secretaries of the Army, Navy, and Air Force was the highest validation of several decades of their combined efforts.
For critical and intelligent deployed embedded modules, air-flow-through (AFT) cooling describes an approach that brings the coolant much closer to heat-generating electronics than standard conduction-cooled approaches. As a result, compared to conduction cooling, AFT increases the amount of power that can be cooled and decreases device temperatures.
For many COTS vendors and VITA members, the Tri-Services Memo issued in January 2019 by the secretaries of the Army, Navy and Air Force was the highest validation of several decades of their combined efforts. The memorandum clearly stated that, going forward, modular open systems approach (MOSA) supporting standards “should be included in all requirements, programming and development activities for future weapon system modifications and new start development programs to the maximum extent possible.” Examples of MOSA standards include the Sensor Open Systems Architecture (SOSA) and CMOSS, both of which rely on OpenVPX hardware as their foundation.
At the 2018 Embedded Tech Trends conference, results were presented from early simulations that conclusively established 100 Gigabit Ethernet could be successfully implemented on VPX using existing and newly announced copper connectors. At that time, many in the industry thought that optical interconnects and fiber would be required to support 100 GbE speeds.
