Interaction with Other OpenStack Service Components

Based on the configuration, the BMSs may interact with other OpenStack services including:

• The OpenStack Telemetry module (Ceilometer) for using IPMI measurement.
• The OpenStack Identity service (Keystone) for requesting identity authentication.
• The OpenStack Image service (Glance) for retrieving images and image metadata.
• The OpenStack networking service (Neutron) for providing DHCP and network configuration.
• The OpenStack Compute service (Nova) is used together with the BMSs to function as the user-oriented API for instance management. The BMSs provide the admin/operator APIs for hardware management. The OpenStack Compute service also provides the scheduling function, tenant quota, IP address allocation, and other services that are not provided by the BMSs.
• OpenStack object storage (Swift) for providing temporary storage for configdrive, user images, deployment logs, and check data.
