Abstract
Systems and methods for detecting types of storage drives connected to a controller, which performs backplane or enclosure management. The controller has multiple pins, which includes N analog pins, such as the PRSNT# pins. Each of the N analog pins is electrically connected to a corresponding detecting circuits. Further, 2*N storage drives may be connected to and controlled by the controller in a way such that each analog pin may be connected to two storage drives via a corresponding detecting circuit for detecting a drive type of each storage drive. Each storage drive may be a SATA/SAS storage drive, or a NVMe storage drive. In operation, the controller receives a voltage from each of the N analog pins, and determines the drive type of each of the two of the 2*N storage drives based on the voltage received from each of the N analog pins.
