Method and System For Near Field Communication (NFC) between Components in a System Chassis

Disclosed is a method and system for Near Field Communication (NFC) between components in a system chassis to self discover, describe, and react to system inventory and behaviors. The method involves adding a NFC device that may be both active and passive to each chassis component. Here, an active device is one where both the target and the initiator can communicate with one another by alternate signal transmission. Alternately, a passive device is powered by the target's electromagnetic field and therefore does not need any power supply. In a passive mode, where no power is available, the component can provide static information. For example, simple presence information can be transmitted in the passive mode. The presence information can be used to provide a basic inventory of the system, without needing to know additional information. In the case of compute nodes, the number of installed compute nodes may be determined. Additional, more detailed information such as serial number and location of the nodes may be provided if the device installed in the component is capable of storing and transmitting this information in the passive mode. Also, in case a component needs to be replaced, this information may be passed on to a higher order component such as Chassis Management Device (CMD). Additionally, instructions regarding the replacement may be brought up or the user may be informed that the CRU/FRU is not compatible in some way.

In the active mode, the components may provide real time information when queried by the CMD...
