QuestionQ122

Troubleshooting and Repairing

The cluster-level backend IOPS performance graph displays a higher-than-normal number of IOPS for back-end storage.

What could be a possible reason for this condition?

  • A Data resynchronization is in progress.
  • B Not enough capacity for slack space is on vSAN datastore.
  • C There is VM storage I/O traffic.
  • D DRS is invoking multiple vMotion migrations.
Explanation

vSAN back-end IOPS include internal replica and resynchronization traffic. Resynchronization caused by repair, policy changes, maintenance-mode evacuation, or rebalancing can increase the cluster’s back-end IOPS. VM I/O is reported as client or VM front-end traffic rather than as the back-end metric.
