Abstract

A system for communication between components in a computer storage system includes a drive enclosure device having a plurality of disk drives. A switch module is electrically coupled to the drive enclosure device. The module has a plurality of physical layer links (PHYs). The module generates out-of-band (OOB) signals to transmit to the drive enclosure device, detects a physical location of an active drive enclosure device by interrogating the PHYs, and sends a serial management protocol (SMP) instruction to the drive enclosure device to perform a task, the SMP instruction based on the physical location.
