The maximum number of virtual volumes that can be placed into a single consistency group in a Dell VPLEX environment is800. This limit is set to ensure the manageability and performance of the consistency group within the VPLEX system.

Here’s a detailed explanation:

Consistency Group Capacity:A consistency group in VPLEX is a collection of virtual volumes that are managed together to maintain write-order fidelity, which is crucial for applications requiring strong consistency guarantees.

Limit Rationale:The limit of 800 virtual volumes is determined based on the VPLEX system’s ability to handle the overhead associated with managing a large number of volumes in a consistency group, including the coordination of writes and snapshots.

Operational Management:By capping the number of virtual volumes in a consistency group, VPLEX ensures that the group can be managed effectively without compromising the performance of the storage system.

Documentation Reference:The Dell VPLEX Operate Achievement documents outline the specifications and limitations of VPLEX systems, including the details of consistency group capacities1.

Best Practices:Administrators are advised to follow best practices and guidelines provided by Dell when configuring and managing consistency groups to avoid exceeding the recommended limits and to ensure optimal system performance.

It’s important for storage administrators to be aware of these limitations when planning and implementing VPLEX storage solutions to ensure they are operating within the supported configurations.
