Hey,

Upstream we are already using device-class as an option,

deviceClass: The CRUSH device class to use for this selection of storage devices. (By default, if a device's class has not already been set, OSDs will automatically set a device's class to either hdd, ssd, or nvme based on the hardware properties exposed by the Linux kernel.) These storage classes can then be used to select the devices backing a storage pool by specifying them as the value of the pool spec's deviceClass field.
https://rook.io/docs/rook/v1.10/CRDs/Cluster/ceph-cluster-crd/#osd-configuration-settings

Here we can apply the settings, https://github.com/rook/rook/blob/5e0cf952281eea41d82a25d45e38bef6a1fc7be4/deploy/examples/cluster.yaml#L240

So we can provide documentation for downstream how to support it,
Or do you also need UI support for it?

Does this answer your question, can we close this issue?

Comment 14 Parth Arora 2023-02-28 11:55:14 UTC

Hey,
Is there anything else you are looking for this BZ,

Or we can go ahead and close this one.
If you want a documentation to abe added for a downstream you can a doc bug for the same.
Thanks!

Please reopen if something else is remaining.
