MULTI-SOCKET SERVER MANAGEMENT WITH RFID

摘要

Radio frequency identification (RFID) tags embedded in processors within a computing system provide a separate communication path to other components of the computing system during initialization processing, apart from the system interconnect. Upon powering up, each processor causes its RFID tag to broadcast data regarding the processor's interconnect location and initialization status. A RFID receiver senses the RFID tags in the Platform Control Hub (PCH), and each processor's interconnect location and initialization status data is stored in registers within the PCH. During system initialization processing, the BIOS accesses these PCH registers to obtain the processor's data. The interconnect location and initialization status data is used by the BIOS to select the optimal routing table and configure the virtual network within the computing system based on the optimal routing table and the RFID tag data, without interrogating each processor individually over the system interconnect.
