What is a consideration when using VPLEX RecoverPoint enabled consistency groups?

When using VPLEX with RecoverPoint enabled consistency groups, it’s important to consider how journals are managed:

Production Journals: These are used by the production volumes for logging write I/Os before they are replicated to the remote site or local copy.

Local Copy Journals: These are used by the local copy volumes for the same purpose as production journals but are specific to the local copies.

Separation of Journals: To ensure proper replication and recovery processes, production and local copy journals must be kept in separate consistency groups.This separation is crucial for maintaining the integrity of the replication and avoiding conflicts between production and local copy operations1.

RecoverPoint Configuration: In a VPLEX environment, RecoverPoint provides continuous data protection and replication.It is configured to work with VPLEX consistency groups to ensure that all writes are captured and can be recovered in case of a failure1.

Best Practices: Dell’s best practices for VPLEX RecoverPoint configurations recommend this separation of journals to ensure that the system can handle failover scenarios correctly and that data is not lost or corrupted1.

By following this consideration, storage administrators can ensure that their VPLEX RecoverPoint environment is configured for optimal data protection and disaster recovery readiness.
