You must follow the guidelines if you use vSphere Replication to protect virtual machines on sites that use Storage DRS or Storage vMotion.

  • vSphere Replication is compatible with vSphere Storage vMotion and vSphere Storage DRS on the protected site. You can use Storage vMotion and Storage DRS to move the disk files of a virtual machine that vSphere Replication protects, with no impact on replication.

  • vSphere Replication is compatible with Storage vMotion and saves the state of a disk or virtual machine when the home directory of a disk or virtual machine moves. Replication of the disk or virtual machine continues normally after the move.

  • A full sync causes Storage DRS to trigger Storage vMotion only if you set the Storage DRS rules to be very aggressive, or if a large number of virtual machines perform a full sync at the same time. The default I/O latency threshold for Storage DRS is 15ms. By default, Storage DRS performs loading balancing operations every 8 hours. Storage DRS also waits until it has collected sufficient statistics about the I/O load before it generates Storage vMotion recommendations. Consequently, a full sync only affects Storage DRS recommendations if the full sync lasts for a long time and if, during that time, the additional I/O that the full sync generates causes the latency to exceed the I/O latency threshold.
