Computer system and method of automaticly detecting and managing slot identifier

Abstract

A computing system for identifying a slot in a server rack includes a server rack and a compute tray. The server rack has an insertion slot with a surface pattern. The insertion slot is associated with a slot identifier. The surface pattern has multiple discrete surfaces. The compute tray includes a first group of light transmitters and a second group of light receivers. Each of the first group of light transmitters outputs emitted light toward a discrete surface of the surface pattern. Each of the respective second group of light receivers detects, based on the emitted light, reflected light from the respective discrete surface of the surface pattern. A processor is communicatively coupled with the respective second group of light receivers. The processor is configured to receive a group of signals indicative of the reflected light from the second group of light receivers. The processor is also configured to determine the slot identifier based on the group of signals.
