Practice question 492 of 506 · hard

Several VM disks on a supported cluster have Storage QoS minimums configured. Monitoring shows the physical storage is saturated and reports insufficient throughput for a policy. What conclusion should guide the response?

Choose the single best answer.

  1. A.A configured minimum IOPS guarantees delivery regardless of physical storage capacity
  2. B.Change an Aggregated policy to Dedicated for every VM and assume this creates enough backend IOPS to satisfy all minima
  3. C.Increase every minimum equally and assume that increases the storage system's total available IOPS
  4. D.QoS cannot create missing physical capacity; investigate contention and capacity, then tune policy allocations and workload placement
Show the answer and explanation

✓ Correct answer

  • QoS cannot create missing physical capacity; investigate contention and capacity, then tune policy allocations and workload placement

QoS distributes available performance and reports when storage cannot meet requested minima. Investigate physical contention/capacity and tune allocation or placement. A minimum cannot guarantee nonexistent capacity; raising every minimum or changing policy scope does not create more backend IOPS.
