Telemetry: Enhancing Customer Triage of Intel® SSDs

by Behnam Eliyahu and Monika Sane

Telemetry refers to an umbrella of tools, utilities, and protocols to remotely extract and decode information for debugging potential issues with Intel® SSDs. Telemetry works over industry standard protocols, and eliminates or minimizes the need to remove SSDs from customer systems for retrieving debug logs. Telemetry thus enables host tools, Intel technical sales specialists, (TSS), Intel application engineers (AEs), and Intel engineering teams to better identify and debug performance excursions, exception events and critical failures in Intel® SSDs, without sending the physical drive to Intel for failure analysis. This capability is designed in accordance with NVMe* 1.3 telemetry specifications as well as corresponding ACS 4 SATA definitions (which are common industry standards), and is expected to accelerate debugging of external and internal bug sightings pertaining to Intel® SSDs. The key difference between NVMe and SATA is the fact that there is no controller-initiated capability on SATA drives.[…]
