Setting the cache-retention policy for Flash Pool aggregates
Beginning with ONTAP 9.4, you can assign cache-retention policies to volumes in Flash Pool aggregates. Data in volumes with a high cache-retention policy remains in cache longer and data in volumes with a low cache-retention policy is removed sooner. This increases performance of your critical workloads by making high priority information accessible at a faster rate for a longer period of time.
Before you begin
You should know whether your system has any conditions that might prevent the cache-retention policy from having an impact on how long your data remains in cache.
