RPCR included features#

RPCR is a prescribed deployment of Red Hat Enterprise Linux OpenStack Platform that contains the majority but not the entirety of available features in Red Hat Enterprise Linux OpenStack Platform. RPCR is tailored to meet specific customer requirements, and includes the following Red Hat Enterprise Linux OpenStack Platform features in the initial release of RPCR:

**RPCR supported features**#
Red Hat Enterprise Linux OpenStack Platform feature	Additional detail
Dashboard (horizon)	OpenStack Dashboard
	Red Hat Enterprise Linux OpenStack Platform Director dashboard
Identity service (keystone)	RBAC Administrator roles Limited-access roles
	LDAP Log in using LDAP credentials Login accounts are created and removed through LDAP directory membership changes Authenticate through a directory query without modifying the directory
	Load users in bulk with appropriate RBAC permissions, without requiring LDAP or ADFS (Identity backed by a DB)
	Support multiple clusters inside a single instance of Identity User access is differentiated between a development cloud and a production cloud while sharing a single Identity instance
	Multi-factor authentication
	Endpoint URLs can be filtered based on role (such as public, or internal)
	The Galera database stores all Identity service data Pacemaker automates recovery of Galera Fencing is not required during recovery
Image service (glance)	Supports the Python API (glance client module), Dashboard, and command-line interfaces
	Can discover, register, retrieve, and delete virtual machine images
	Can query VM meta-data
	Supported back ends: Converged Storage service (ceph) (preferred) NetApp (optional)
Object storage service (swift)	Backed by Converged Storage service (ceph) Swift API calls ceph (RADOS Gateway) Supports most swift functions including: Authentication Swift ACLs Meta-data List, create, delete objects Get, copy objects Get, update object meta-data Does not support: Expiring objects Object versioning CORS Static Web sites
	Migration between ceph and swift back ends is a manual customer-led migration for which Rackspace does not provide support Plan for size in the beginning as opposed to attempting a migration in the future
Block Storage service (cinder)	Supported back ends: Converged Storage service (ceph) (preferred) NetApp (optional)
	Multi back-end support
	Quotas
	Import and export
	Live snapshots
	Scheduled snapshots
Converged Storage service (ceph)	Five node deployment minimum
	Shared storage solution for Block Storage
	User-space module is used for RADOS for ceph
	Requires a public network and a private network for cluster management
NetApp	Optional
Compute service (nova)	KVM on Red Hat
	Manage compute resources (disk, network, CPU, memory) Ability to adjust settings after configuration without losing the instance
	Local storage
	Ability to assign or reassign IPs to VMs
	RBAC
	Flavors Create catalog of flavors Add/remove/update flavor list
	Image service (glance) Scheduled image snapshots
	LAN management
	Regular migrations (non-live)
	Live migration. Shared storage, such as ceph, enables live migration of guests from one hypervisor to another. This provides a way to bring a hypervisor down for maintenance without impacting the guests, and enables Rackspace to perform low impact upgrades to the cloud.
Networking service (neutron)	VXLAN ML2 Plug-in + OVS Plug-in VXLAN overlays
	PLUMgrid (fast follow) Demarcation between Networking (neutron) API and PLUMgrid PLUMgrid support provided by PLUMgrid team
MaaS	Monitoring of relevant performance and stability information
	Grafana templates
Orchestration service (heat)	Called by Director in the Undercloud to deploy and manage the Overcloud
	Available in the Overcloud to create, update, and manage groups of cloud resources and their software components as a single unit. Used for automated, repeatable deployments with templates.
	Supports Image service (glance)
	Heat-api-cfn support (AWS-style query API)
Red Hat Enterprise Linux OpenStack Platform Director (with Puppet)	Manages all of the Overcloud pieces (nova, keystone, glance, swift, neutron) Controller nodes contain the following components: horizon, keystone, nova API, neutron server, Open vSwitch, glance, cinder volume, cinder API, swift storage, swift proxy, heat engine, heat API, MariaDB, RabbitMQ. The controller also uses Pacemaker and Galera for high availability. Compute nodes contain the following components: Compute, nova KVM, Open vSwitch. Converged Storage service (ceph) nodes contain a ceph Object Storage Daemon (OSD). Object Storage (swift) nodes contain the following components: swift object and container services, Open vSwitch. Block Storage (cinder) nodes contain the following components: cinder volume, Open vSwitch.
	Deploys using Ironic against hardware
	Requires IPMI interface
	Used to adjust parameters after deployment
	Live migration
	In-place updates
	Add, remove resources
	Controller node recovery using Pacemaker (STONITH)
	Uses RabbitMQ
	Uses MariaDB
	Overcloud validation using provided Tempest tests
	Support for integration of custom Puppet configurations (Customer data center integration) Puppet configurations provided by the customer and added to Director by Rackspace
	RackConnect v.3, utilizing F5
