Doc Text:	For Distributed Compute Node deployments which use storage, `dcn-hci.yaml` has been renamed to `dcn-storage.yaml` because DCN sites with storage have the option of not using HCI (Hyper-Converged Infrastructure). `dcn-hci.yaml` is deprecated but will remain in the environments directory for backwards compatibility. `dcn-hci.yaml` will be removed in Red Hat OpenStack platform 17. `dcn-storage.yaml` should be used in place of `dcn-hci.yaml`.

Description John Fulton 2020-08-13 12:44:59 UTC

All of our DCN with Storage testing has been deployed using HCI (Computes + OSDs). 
We expect using separate compute nodes and separate ceph-storage nodes to "just work".
However, we want to conduct a test of this in a DCN deployment to be sure.

Comment 9 John Fulton 2020-12-02 16:38:45 UTC

This is no longer test-only as we need a small patch in THT to support this.

Though the existing DCN environment and DistributedCompute role will deploy Glance on the edge, it won't easily deploy Cinder A/A without adding that missing Cinder block service.

Comment 10 Alan Bishop 2021-01-23 17:38:36 UTC

Patch merged on stable/train and should be automatically imported for 16.2.

Comment 11 John Fulton 2021-01-27 18:05:16 UTC

Because we should include the rename of an enviornment file I'm setting this back to ON_DEV and setting myself as the engineering assignee.
