This is a medium to advanced session on two relatively new features in Cinder. First we will look at the new replication feature which will be available in the Mitaka release. We will show how to configure and utilize replicated volumes in your storage catalog. We plan to have 2 short demos of replication configurations, one from SolidFire and one from NetApp. In the second part of the presentation we will discuss the configuration details necessary in Cinder (and OpenStack) to allow live migration of instances to work with block storage attached.
Key takeaways from this session will include:
- Complete configuration example for replicated volume type.
- An understanding of the features and limitations of Cinder replication during both normal operation and failover.
- The configuration requirements for live migration related to block storage.
