Abstract
A data storage device includes a controller. The controller is coupled to a host device. The controller is configured to determine a quality of a peripheral component interconnect express (PCIe) link, wherein the quality of the PCIe link is either greater than or less than a threshold quality, and transmit an error notification to the host device via a sideband when the quality of the PCIe link is less than the threshold quality. The sideband is a different communication channel than the PCIe link. The error notification includes additional information regarding events occurring in the data storage device resulting in the quality of the PCIe link.
