  • ONTAP 9
  • Active IQ Unified Manager 

Answer

  • Performance Capacity is a new feature that ONTAP 9 and Active IQ Unified Manager (AIQUM) together support, which allows you to proactively monitor performance headroom in your storage environment.
  • This feature helps storage administrators address the following concerns:
    • Where is the best place to create a new volume / LUN?
    • Where can this volume / LUN be moved to?
    • Is this cluster over utilized?
    • Is a particular cluster resource over utilized?
    • When will this cluster become over utilized?
Details of Performance Capacity
  • ONTAP measures headroom as a basic calculation per node.
  • AIQUM does more calculations to find the optimal point for CPU and IOPS.
  • This calculation is the point that CPU and IOPS can go the highest before incurring extra storage latency, like the graphic below.

Additional Information

Similar metrics can be obtained from ONTAP CLI to help determine if a node is over utilized.
