Issue/Introduction

The <dx-platform>/tools/dbench-fio.sh script allows to Benchmark Kubernetes persistent disk volumes with fio: Read/write IOPS, bandwidth MB/s and latency.
It is based on https://github.com/leeliu/dbench, it launches benchmark daemonset pods on all the nodes and runs the fio commands.

This script will help you verify and ensure throughput for NFS storage is as per DX Platform hardware requirement:
