D-VPX-DY-A-24 Exam Dumps : Dell VPLEX Deploy Achievement

The maximum number of synchronous consistency groups supported by VPLEX is 256. This number is determined by the system’s capabilities and is designed to ensure optimal performance and manageability.

Consistency Groups: Consistency groups in VPLEX are used to group multiple virtual volumes together to ensure write-order fidelity, which is crucial for applications requiring transactional integrity12.

Synchronous Operations: Synchronous consistency groups are particularly important for environments where data must be kept consistent across geographically dispersed clusters in real-time12.

System Limitations: The limit of 256 synchronous consistency groups is set to balance the system’s performance with the need for data consistency. It ensures that the system can maintain the required performance levels while providing the data protection and availability features12.

Configuration and Management: Administrators must carefully plan and manage the consistency groups within the limits of the system to ensure that all critical data is protected and that the system operates efficiently12.

Documentation Reference: For detailed information on configuring and managing consistency groups, administrators should refer to the Dell VPLEX Deploy Achievement documents and best practice guides12.

In summary, the verified answer to the maximum number of synchronous consistency groups supported by VPLEX is 256. This limitation is part of the system design to ensure high availability and performance.

"The MetroPoint topology can maintain up to five copies of data, including one remote copy and one local copy at each VPLEX site. It provides protection for each of the VPLEX Metro sites with continuous local replication via RecoverPoint"..

When using VPLEX with RecoverPoint enabled consistency groups, it is important to ensure that local copy volumes and production volumes are placed in separate consistency groups. This separation is crucial for maintaining the integrity of the data replication and recovery processes.

Consistency Group Configuration: Consistency groups in VPLEX are logical groupings of virtual volumes that VPLEX treats as a single unit for operations such as data mobility and recovery. When RecoverPoint is enabled, these groups also align with RecoverPoint consistency groups for replication purposes1.

Separation of Volumes: Keeping local copy volumes (volumes used for local replication) and production volumes (active volumes serving data to hosts) in separate consistency groups helps to prevent any potential conflicts or issues with replication and ensures that the local copies are consistent and usable for recovery1.

RecoverPoint Replication: RecoverPoint provides continuous data protection and replication for recovery to any point in time. The separation of volumes into different consistency groups helps to manage and maintain the replication process effectively1.

Operational Management: By separating these volumes into different consistency groups, administrators can manage operations such as replication, failover, and recovery with greater precision and control1.

Best Practices: This separation is part of the best practices recommended by Dell EMC when configuring VPLEX with RecoverPoint, ensuring that the system operates efficiently and that data is protected in case of any failures1.

In summary, when using VPLEX with RecoverPoint enabled consistency groups, local copy volumes and production volumes must be placed in separate consistency groups to ensure proper replication and recovery processes.
