In a data center designed for high availability, a company is implementing a VPLEX solution to ensure continuous access to data across geographically dispersed locations. The architecture includes two data centers, each equipped with a VPLEX cluster. The company needs to determine the optimal configuration for synchronous replication to minimize latency while maximizing data availability. If the round-trip latency between the two sites is measured at 10 milliseconds, what is the maximum distance (in kilometers) that can be supported for synchronous replication, assuming the speed of light in fiber optic cables is approximately 200,000 kilometers per second?
