Aread missoccurs when the data requested by the host isnotavailable in the cache. As a result, the storage system must fetch the data from the slower disk storage (back-end), leading to higher latency.

Cache hit:Data is already in cache → faster response.

Cache miss (read miss):Data not in cache → fetched from the disk.

Intelligent storage systems incorporate advanced features like automated tiering, deduplication, and compression. These features enable efficient storage utilization and optimized management by automating data placement and reducing manual intervention.

Option A: While intelligent systems may facilitate cloud integration, they do not guarantee cost-free migration.

Option B: Data reduction features help, but the primary advantage is broader efficiency and optimization.

Option C: Creating silos increases complexity; intelligent systems aim to unify and simplify storage management.

Anincidentis anunplanned disruptionof a service or a reduction in its quality, often with anunknown root cause.

Incidents require immediate action to restore service.

Example: SAN switch port down, unexpected storage latency.

Support requestsare typically service requests, not incidents.

Impact actionsare more about changes, not incidents.

Events preventing correctionsmight be problems, not incidents.
