Description Martin Bukatovic 2022-07-25 14:39:13 UTC 
Describe the issue
==================

In the documentation, we are referencing to minimal hw requirements for Ceph,
but we are not doing this for OCP clusters where ODF will be installed: the hw
requirements (cpu, disk and ram) for OPC/ODF clusters are not explicitelly
stated.

Describe the task you were trying to accomplish
===============================================

Setup Metro DR with Advanced Cluster Management cluster environment from
scratch.

Suggestions for improvement
===========================

In the Metro DR documentation, we should explicitelly state that:

- for MetroDR OCP/ODF clusters, hw requirements of external ODF clusters apply
- link to the ODF "Planning your deployment" guide, where the requirements
  are explained in detail

We don't need to repead any information which is already present in the ODF
planning guide.
