What is the maximum distance supported by VPLEX Geo for synchronized data access?

The maximum distance supported by VPLEX Geo for synchronized data access is indeed up to 100 km. VPLEX Geo utilizes a combination of VMware vMotion and synchronous replication to allow data to be accessed across geographically dispersed locations. This capability is crucial for providing high availability and disaster recovery without sacrificing performance.

The 100 km limit ensures that latency remains low enough to support synchronous operations, which is essential for applications that require real-time data consistency. Beyond this distance, the latency might inhibit the effective performance of synchronous data access, as the time taken for data to travel back and forth could introduce delays that compromise the reliability of the service.

In contrast, longer distances like those represented in other options, such as 200 km or 300 km, would pose technical challenges related to latency and data consistency requirements, making them unsuitable for VPLEX Geo setups utilizing synchronized access. Therefore, the specification of up to 100 km reflects the design and operational limits of the technology to ensure optimal performance.
