What type of data access does VPLEX enable across geographically separated sites?

VPLEX enables synchronous data access across geographically separated sites, which is crucial for ensuring data consistency and integrity in environments where applications require real-time access to data. Synchronous data access means that read and write operations are completed on both primary and secondary storage simultaneously, so all changes are immediately available across all sites. This real-time replication is essential for applications requiring high availability and disaster recovery, as it ensures that the data is always current and reduces the risk of data loss during failover scenarios.

The synchronous nature of VPLEX also supports environments where users and applications might be located far apart but still need to interact with the same dataset without delay. This capability is particularly significant for organizations that have implemented a distributed architecture and need to maintain operational continuity and performance across their sites, regardless of geographical distance. In contrast, asynchronous data access, which involves delays between write operations at both locations, does not provide the same level of immediacy and could lead to data inconsistencies if not managed carefully.
