Solid State Drives

Description

Solid-state drives (SSDs) have a more predictable end-of-life as compared to hard-disk drives (HDDs). Hence 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
