Preparing the storage environment for SRA
Prepare the storage environment for IBM Storage Ceph Storage Replication Adapter based on your disaster recovery configuration.
Before you install and configure IBM Storage Ceph Storage Replication Adapter, prepare the storage environment according to the disaster recovery model that you plan to use.
SRA supports both snapshot mirroring and stretch cluster disaster recovery configurations.
- Snapshot mirroring
- Uses snapshot-based replication between protected and recovery clusters to enable disaster recovery operations.
- Stretch cluster configurations
- Uses a single Ceph cluster that spans two locations. Disaster recovery operations are location-based and do not rely on replication between clusters.
Select the appropriate procedure based on your configuration:
- Preparing the storage environment for mirrored configurations
- Preparing the storage environment for stretch cluster configurations
Important: Ensure that the storage environment is configured according to the selected disaster recovery model before you install and configure SRA.
