----------------------------------
Labels: pull-request-available (was: )
> [Docs] Best practices for heterogeneous deployments
> ---------------------------------------------------
>
> Key: HDDS-15597
> URL: https://issues.apache.org/jira/browse/HDDS-15597
> Project: Apache Ozone
> Issue Type: Task
> Components: documentation
> Reporter: Wei-Chiu Chuang
> Priority: Major
> Labels: pull-request-available
>
> Add to existing docs or create a new page to discuss heterogeneous
> deployments: different deployment strategies, pros and cons, and
> recommendations.
> Deployment options to be considered:
> * datanodes of different number of disks, different capacities.
> * racks of different data density.
> The goal is to keep the data as balanced as possible across disks, datanodes
> and racks. Therefore, data traffic is balanced.
> The discussion must take into account the current Ozone's capabilities and
> limitations. E.g. rack-scatter and rack-aware policies do not consider the
> data density of the racks and the data density of datanodes within the same
> rack; storage policy is yet to be developed. It must also ensure the
> maintenance is easy, and allows new capacity to be added incrementally easily
> into the cluster.
> The write style must be technical, but simple to read.
