In this section describe the unique components that make up the scenario, +.. what each component provides and why it has been included in order +.. to communicate to the user the capabilities available in this scenario. + +This scenario deploys the High Availability OPNFV Cloud based on the +configurations provided in ha_nfv-kvm_heat_ceilometer_scenario.yaml. +This yaml file contains following configurations and is passed as an +argument to deploy.py script + +* scenario.yaml:This configuration file defines translation between a + short deployment scenario name(os-nosdn-kvm-ha) and an actual deployment + scenario configuration file(ha_nfv-kvm_heat_ceilometer_scenario.yaml) + +* deployment-scenario-metadata:Contains the configuration metadata like + title,version,created,comment. + +* stack-extensions:Stack extentions are opnfv added value features in form + of a fuel-plugin.Plugins listed in stack extensions are enabled and + configured. + +* dea-override-config: Used to configure the HA mode,network segmentation + types and role to node assignments.These configurations overrides + corresponding keys in the dea_base.yaml and dea_pod_override.yaml. + These keys are used to deploy multiple nodes(3 controllers,2 computes) + as mention below. + + * **Node 1**: This node has MongoDB and Controller roles. The controller + node runs the Identity service, Image Service, management portions of + Compute and Networking, Networking plug-in and the dashboard. The + Telemetry service which was designed to support billing systems for + OpenStack cloud resources uses a NoSQL database to store information. + The database typically runs on the controller node. + + * **Node 2**: This node has Controller and Ceph-osd roles. Ceph is a + massively scalable, open source, distributed storage system. It is + comprised of an object store, block store and a POSIX-compliant distributed + file system. Enabling Ceph, configures Nova to store ephemeral volumes in + RBD, configures Glance to use the Ceph RBD backend to store images, + configures Cinder to store volumes in Ceph RBD images and configures the + default number of object replicas in Ceph. + + * **Node 3**: This node has Controller role in order to achieve high + availability. + + * **Node 4**: This node has Compute role. The compute node runs the + hypervisor portion of Compute that operates tenant virtual machines + or instances. By default, Compute uses KVM as the hypervisor. + + * **Node 5**: This node has compute role. + +* dha-override-config:Provides information about the VM definition and + Network config for virtual deployment.These configurations overrides + the pod dha definition and points to the controller,compute and + fuel definition files. + +* os-nosdn-kvm-ha scenario is successful when all the 5 Nodes are accessible, + up and running + +Scenario Usage Overview +======================= +..
