CinderVolumeEdge is an optional service (defaults to OS::Heat::None)
that can be enabled on DCN/Edge nodes for edge sites that support
persistent block storage (i.e. cinder). The dcn-hci.yaml environment
file enables the service.
The new service supports the following edge deployment models:
1. Edge site with no block storage
- Deploy DistributedCompute nodes
- Use dcn.yaml environment file (the CinderVolumeEdge service
remains disabled)
2. Edge site with traditional HCI storage
- Deploy DistributedComputeHCI nodes
- Use dcn-hci.yaml env file to enable the CinderVolumeEdge service
- Use ceph-ansible.yaml env file to deploy ceph for the RBD backend
3. Edge site with quasi-hyperconverged storage
- Deploy DistributedCompute nodes
- Use dcn-hci.yaml env file to enable the CinderVolumeEdge service
- Use ceph-ansible-external.yaml env file so the RBD backend can
access an external ceph cluster
This patch adds support for number 3, which is a new capability. Whereas
traditional HCI means ceph and cinder services run on compute nodes, the
new model is still quasi-hyperconverged because cinder (as well as
glance) runs on the compute nodes.
