Release Notes

This is the first release of Trilio Site Recovery for OpenStack, providing self-service disaster recovery for Nova VMs. The API enables OpenStack tenants to replicate Cinder volumes to a secondary site using Pure Storage FlashArray and automate failover, failback, and DR testing workflows.

New features

Volume Replication via Pure Storage FlashArray
Replicate Cinder volumes attached to Nova VMs from a primary OpenStack site to a secondary site using Pure Storage FlashArray replication. Ensures data consistency and readiness for recovery at the target site.
Automated Failover
Trigger a failover to the secondary OpenStack site through the API, automatically promoting replicated volumes and recreating Nova VM instances at the target site to restore workloads after a disaster event.
Automated Failback
Restore workloads back to the primary OpenStack site once it is available again. The failback workflow reverses replication direction and recreates VMs on the original site with minimal manual intervention.
Non-Disruptive DR Testing
Validate disaster recovery readiness without impacting production workloads. Spin up test instances at the secondary site from replicated volume snapshots, verify recoverability, and tear down the test environment — all without interrupting live VMs.
Self-Service Tenant API
Expose all disaster recovery operations — replication configuration, failover, failback, and DR testing — through a tenant-scoped REST API, empowering OpenStack tenants to manage their own DR without requiring operator intervention.
