DXserver processes are maxing out the IOPS on the VMs in Azure

Products

• CA Directory

Issue/Introduction

All of sudden you may experience that the IOPS (Input / Output Operations Per Second) climbing to 100% at certain times of the day (e.g. in the morning until the end of the day) and this keeps repeating every day.

Resolution

Problem is related to IPOS being set too low at Operating System level. Try to raise (e.g. make it 2x) the current IOPS at OS level.

For example: If the current IOPS value is set to 500, raise it to 1100.

Once done, monitor with Performance Analyzer Tool and you will notice the IOPS being stabilized at lower % usage compare to what you have originally seen. Meaning not at 100%.
