Intensive I-O with Synchronous Replication

Description

Due to the nature of synchronous replication (blocking volume writes while waiting for a response from the target system), you may experience sluggish behavior with any applications that are writing to the mirrored volume. The frequency of these events could be high depending on the ratio of “Volume I/O traffic” to “system resource”. It is recommended that you use asynchronous replication when continuous and intensive I/O traffic is anticipated for the volume or when SIOS DataKeeper is used on a low bandwidth network.
