What does the term 'data consistency' refer to in VPLEX?

The term 'data consistency' in the context of VPLEX refers specifically to ensuring that copies of data are identical across multiple sites or systems. This is crucial in environments where data is accessed and modified simultaneously from different locations, as it ensures that all users work with the same, up-to-date information.

In VPLEX, data consistency plays a vital role in maintaining the integrity of data during operations like virtualization and providing a seamless experience to end-users, particularly in disaster recovery scenarios or when data is shared across different geographical locations. The consistent state of data is a key factor for applications that require real-time or near-real-time synchronization between locations, ensuring that no discrepancies arise when accessing or updating the data.
