How Chassis Management Improves OpenVPX System Development
VITA 46.11 defines a chassis management architecture for OpenVPX that provides automated oversight and administration tools, offering better insights into a system’s health. As more intelligent monitoring functions are implemented in OpenVPX applications, the need to ensure smooth system operation and effective resource management becomes increasingly important.
A Chassis Manager has three primary functions to help keep systems healthy, manage system power and ensure proper cooling (Figure 1):
Resource management: discover all intelligent FRUs (IPMCs), boards, and sensors in the chassis, as well as any other components that support VITA 46.11
Event monitoring: provide a history of all events on the sensors for each FRU, such as an over-temperature or an under-voltage condition
Diagnostics and response: flag any abnormal or failed sensors or fans, as well as clogged filters; adjust fan speed for irregular temperature conditions; report or shut down due to over-/under-voltage/current conditions
