Question
A six-node all-flash vSAN cluster has been deployed. Deduplication and compression are enabled. All virtual machines are produced by policies with the rule Primary level of failures to tolerate set to 1. How is a vSAN disk group impacted when the cache device belonging to that disk group fails?
Options
- AThe capacity devices are automatically reassigned to another disk group in the same host.
