PowerFlex: Support Matrix for OpenStack and Red Hat OpenStack

Validate PowerFlex compatibility

The Elab support matrix docs only contain RHOSP support, even though the topic states OpenStack, see the screenshot below.
https://elabnavigator.dell.com/eln/modernHomeSSM > Simple Support Matrices > Software Solutions > Cloud Management > OpenStack > search for PowerFlex


For example:
PowerFlex 3.6.2 is supported with operating system RHEL 9.2, and RHOSP 17.1 (using Cinder 3.5.7)


It is suggested first to check the PowerFlex release notes, as OpenStack support can be found there.

For example:
PowerFlex 3.5 was released with support for OpenStack Ussuri.

Validate OpenStack compatibility

Once we have the PowerFlex side covered, we must go to OpenStack's official documentation for any other information pieces or to broaden existing information.
https://docs.openstack.org/ > Configuration Guides > Configuration Reference > Block Storage service (cinder) > Volume drivers > Dell EMC VxFlex OS (ScaleIO) Storage driver > Supported VxFlex OS and ScaleIO Versions.

Validate RHOSP compatibility

As mentioned in the first validation section, Elab support matrix docs only contain RHOSP support.

After covering the PowerFlex side, see Red Hat's official documentation for additional information:
https://access.redhat.com/ > Products and Services > Ecosystem Catalog > Red Hat OpenStack Platform > Software > Dell Technologies PowerFlex > Certifications

The OpenStack version on which RHOSP is based can be found in the "About this release" paragraph in the RHOSP release notes:
https://access.redhat.com/ > Products and Services > Product Documentation > Red Hat OpenStack Platform > 16.1 > Release Notes > Chapter 1. Introduction

For example:
RHOSP version 16.1 running on RHEL 8.2 is supported with PowerFlex 3.5 and 3.6.
