Monitoring the health, power, and cooling of boards used in military systems is just as important as the performance of the end system. System Management directly benefits the warfighter by providing reconfigurability for faster redeployment and health monitoring in the event that elements of the chassis start to fail. 

The "1.1 System Manager" module is a key component to the Sensor Open Systems Architecture™ (SOSA) Technical Standard.  The SOSA Technical Standard describes the System Manager module as providing “system management functionality to and for managed SOSA modules, PICs, and other hardware elements (e.g., power supplies, network switches). Functionality is provided via a set of system management services. The ability to manage and interact with these system management services is enabled through well-defined sets of APIs and sensor component messages.” 

The System Manager module relies heavily on the ANSI/VITA 46.11-2022 standard "System Management on VPX", which provides the key components for monitoring the health, power, and cooling of SOSA plug-in cards and chassis infrastructure, and offers the means to not-only quickly and accurately find and correct faults, but also provide valuable data for predicting future faults.  As a result, the System Manager module is an important element of the overall SOSA architecture. 

In this webcast we will examine what the 1.1 System Manager module is, how ANSI/VITA 46.11 fits into it, and what features SOSA requires of SOSA aligned hardware elements including Chassis Management Modules (CMMs), and individual plug-in cards’ and Power Supply Unit’s Intelligent Platform Management Controller processors.
