Applies to

  • Solid-State Drive (SSD)
  • AFF/FAS Systems

Description

  • Solid-state drives (SSDs) have a more predictable end-of-life as compared to hard disk drives (HDDs).
  • SSDs of the same make and model deployed at the same time on the same system are highly likely to reach end-of-life around the same time.
  • When an SSD reaches 100% of rated life, it might not be able to retain data while powered off for long periods of time.
  • SSDs in this state have an increased risk of data loss.
  • ONTAP includes certain Event Management System (EMS) messages to inform customers of the impending end-of-life of their SSDs.

 
ONTAP generates an event when the rated life of an SSD reaches any of the following three (3) thresholds:

  1. Rated life used >= 90% AND < 95%: shm.threshold.ratedLife
  2. Rated life used >= 95% AND < 100%: shm.threshold.ratedLife2
  3. Rated life used = 100%: shm.threshold.ratedLifeMax
  • The event messages also give an estimate of the number of weeks of rated life remaining for each SSD, based on past usage.
