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.
