Method and System for Managing Electronic Devices using Electromagnetic Interference (EMI) Signatures

Typically, management of electronic devices involves making management elements smarter which incurs a cost or a performance penalty. For example, adding capability of performance metric reporting involves processing overhead and intelligence which makes firmware more complex.

Disclosed is a method and system for managing electronic devices using Electromagnetic Interference (EMI) signatures. All electronic devices include a physical attribute of an EMI signature. This physical attribute can be measured and utilized for management purposes without impacting performance or adding complexity to electronic devices which are managed. The EMI signatures perform management tasks such as detecting data mismatch, computing bandwidth usage or detecting bottleneck.

In a computing environment, the EMI signatures of memory chips can be compared to identify a data mismatch on low complexity hardware without a performance penalty. Further, a similarly non-intrusive load measurement of an Ethernet port can be performed using the EMI flux as an indicator of usage. A diagnostic test can be performed by applying a state (a certain data value) that should produce a known EMI signature. The produced EMI signature can be used to detect issues such as grounds, shorts, visible light output on a screen, etc.

Thus, the disclosed method and system manages electronic devices without overh...
