NFC communication with an information handling system supplemented by a management controller and advertised virtual tag memory
First Claim
1. An information handling system comprising:
- a chassis operable to support processing components;
a processor disposed in the chassis and operable to execute instructions for processing information;
memory disposed in the chassis and interfaced with the processor, the memory operable to store the instructions and information;
a management controller disposed in the chassis and interfaced with the processor, the management controller operable to manage operational conditions associated with processing components within the chassis including at least the processor;
a near field communication (NFC) transceiver disposed in the chassis and operable to wirelessly communicate with an NFC device external to the chassis, the NFC transceiver having a tag memory that stores information to transmit to the external NFC device and information received from the external NFC device; and
a microcontroller interfacing the management controller with the near field communication transceiver, the microcontroller managing the tag memory to adapt the NFC transceiver communications to a selected one of plural data transfer modes including at least populating tag memory with data to replace data read from the tag memory as the data is read so that a tag memory read event provides an amount of data greater than the tag memory size.

Abstract
Near Field Communication (NFC) supports server information handling system management through communication between a mobile information handling system and a baseboard management controller. Enhanced transfer by NFC of management information is provided by manipulating the NFC tag memory assigned for information transfer with the aid of a microcontroller coordinating NFC transfers at the baseboard management controller, such as with coordinated storage operations at a tag memory an supporting processors/microcontrollers. The microcontroller manages tag memory and/or system memory so that the portable information handling system writes and reads information beyond the capabilities of unaided tag memory.

9. A method for communication of information to a server information handling system management controller from an external information handling system having a near field communication (NFC) device, the method comprising:
-
exchanging NFC configuration information between the external NFC communication device and an NFC transceiver disposed in the server, the NFC transceiver having a tag memory, the configuration information including tag memory configuration information of the tag memory of the NFC transceiver indicating a selected one of plural data transfer modes; and communicating information between the external NFC communication device and the NFC transceiver according to the selected one of plural data transfer modes as indicated by the tag memory configuration information; wherein the selected one of plural data transfer modes include at least a tag memory size greater than the NFC transceiver tag memory, the data transfer mode adding data to the tag memory as data is read from the tag memory. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for NFC transfers of information, the system comprising:
-
a portable information handling system having an NFC communication device and an NFC application stored in non-transitory memory, the NFC application operable to command the NFC communication device to send information to another NFC communication device according to configuration information shared with the other NFC communication device; and a server baseboard management controller operable to manage operations of a server information handling system and having an NFC transceiver operable to communicate information stored in a tag memory, the NFC transceiver managed by a microcontroller; wherein the microcontroller manages configuration information sent to the NFC communication device to represent the tag memory with configuration information that differs from the actual configuration of the tag memory, the configuration information including at least a tag memory size greater than the actual tag memory size of the NFC transceiver tag memory, the microcontroller writing information into the tag memory as information is read from the tag memory so that the amount of information provided by a tag memory read exceeds the amount of information stored in the tag memory at the start of the tag memory read. - View Dependent Claims (17, 18, 19, 20)
