The storage replica supports only synchronous I/O (Input/Output) operations. This means it facilitates real-time mirroring of data between servers, clusters, or extended cluster nodes, allowing simultaneous read and write operations at two different locations. It also supports both synchronous and asynchronous replication, with synchronous replication ensuring real-time data mirroring for continuous availability[1][2][5]. However, note that the support for synchronous I/O may vary based on specific configurations and versions, and future updates might introduce changes[1].
