Recap on RHEL OSP 6.0 (Juno) Session title Session title Confidential Non confidential
What s the latest in RHEL OSP 6.0? OpenStack Compute (Nova) Support for NUMA and vcpu topology configuration SR/IOV port support for guests where supporting hardware is available Continual improvement on live-upgrade support Support for serial console Technology Preview for Ironic - Bare-metal Nova Driver Evacuation to scheduled host Previous versions of Nova meant specifying a host to evacuate to Now, Nova asks the scheduler to re-place instances after a migration
What s the latest in RHEL OSP 6.0? OpenStack Block Storage (Cinder) Support for volume replication where backend driver permits for disaster recovery purposes Implements bandwidth restrictions on volume-copy to help with QoS Many new plugins/drivers, e.g. FusionIO, XtremIO, Datera (all certification pending) OpenStack Identity Service (Keystone) Multi-backend for multiple-domains, i.e. an external backend per domain PKI token compression to ease data throughput Configurable hash algorithm for PKI; default is still MD5, but SHA256 recommended
What s the latest in RHEL OSP 6.0? OpenStack Networking (Neutron) Full IPv6 support for tenant and provider networks High Availability for Neutron routers (via VRRP) Distributed Virtual Routing (DVR - Tech Preview) Allows multi-host routing for throughput and availability Further parity with nova-network
What s the latest in RHEL OSP 6.0? OpenStack Data Processing (Sahara) Will be fully supported in RHEL OSP 6.0 (previously technology preview) Certification of both HortonWorks and Cloudera distributions Hadoop 2.4.0 support Ceph Integration Support for Ceph RBD-backed ephemeral storage Permits diskless compute nodes and live-migration Now supports copy-on-write (Glance image > Nova ephemeral disk)
Update on RHEL OSP 7.0 (Kilo)
What s coming in RHEL OSP 7.0? Based on the upstream Kilo release, expected July 2015 Major new features and changes include- Trove (DBaaS) - Fully supported DNS-as-a-Service (Designate) - Technology Preview File share (-as-a-service, Manila) - Technology Preview Operational Tools - Technology Preview Evolution of installation and management platform - RHEL OSP Manager Looking into VM/ High Availability
What s coming in RHEL OSP 7.0? OpenStack Networking (Neutron) Full-support for Distributed Virtual Routing (DVR) - what is this?
Distributed Virtual Routing (DVR) Pre-DVR Topology- DNAT w/floating IP s External Network Host A Host B L3 Agent SNAT Tenant Network
Distributed Virtual Routing (DVR) Pre-DVR Topology- DNAT w/floating IP s External Network Host A Host B L3 Agent Single Point of Failure SNAT Tenant Network
Distributed Virtual Routing (DVR) With DVR, routing for instances without floating IP s still goes via L3 agent External Network Host A Host B L3 Agent SNAT Tenant Network
Distributed Virtual Routing (DVR) With DVR, routing for instances with floating IP s goes via compute nodes themselves DNAT w/floating IP s External Network Host A Host B SNAT L3 Agent SNAT - No Floating Tenant Network
What s coming in RHEL OSP 7.0? OpenStack Networking (Neutron) Full-support for Distributed Virtual Routing (DVR) Per-port security group implementation - i.e. remove anti-spoof/filtering IPv6 everywhere - will include API s, message-bus, database, etc. DPDK-enabled/accelerated Open vswitch (Tech Preview)
What s coming in RHEL OSP 7.0? OpenStack Compute (Nova) Full-support for Ironic (Bare-metal as a Service) Support for file-system quiescing (via guest agent) - consistent snapshots Support for vhost-user virtual interface plugging
What s coming in RHEL OSP 7.0? OpenStack Compute (Nova) Full-support for Ironic (Bare-metal as a Service) Support for file-system quiescing (via guest agent) - consistent snapshots Support for vhost-user virtual interface plugging OpenStack Volume Service (Cinder) Snapshot-based Backup support - volume remains online during backup Import/Export of Snapshots - Re-import existing volumes via metadata Volume multi-attach - attach volumes to multiple instances simultaneously Private volume types - restrict certain storage tiers to select users
What s coming in RHEL OSP 7.0? OpenStack Identity (Keystone) Hierarchy support - nested projects, sub-admin support Federation support - authenticate against external providers, SAML and OpenID Switch over to Keystone v3.0 API - most services currently use v2.0.
