Compatibility of vSphere Replication with Other vSphere Features

vSphere Replication is compatible with certain other vSphere management features.

You can safely use vSphere Replication in combination with certain vSphere features, such as vSphere vMotion. Some other vSphere features, for example vSphere Distributed Power Management, require special configuration for use with vSphere Replication.

Table 1. Compatibility of vSphere Replication with Other vSphere Features

vSphere Feature	Compatible with vSphere Replication	Description
vSphere vMotion	Yes	You can migrate replicated virtual machines by using vMotion. Replication continues at the defined recovery point objective (RPO) after the migration is finished.
vSphere Storage vMotion	Yes	You can move the disk files of a replicated virtual machine on the source site using Storage vMotion with no impact on the ongoing replication.
vSphere High Availability	Yes	You can protect a replicated virtual machine by using HA. Replication continues at the defined RPO after HA restarts a virtual machine. vSphere Replication does not perform any special HA handling. You can protect the vSphere Replication appliance itself by using HA.
vSphere Fault Tolerance	No	vSphere Replication cannot replicate virtual machines that have fault tolerance enabled. You cannot protect the vSphere Replication appliance itself with FT.
vSphere DRS	Yes	Replication continues at the defined RPO after resource redistribution is finished.
vSphere Storage DRS	Yes	You can move the disk files of a replicated virtual machine on the source site using Storage DRS with no impact on the ongoing replication.
VMware Virtual SAN datastore	Fully supported in vSphere Replication 5.5.1. Experimental support in vSphere Replication 5.5.	You can use VMware Virtual SAN datastores as the source and target datastores when configuring replications. Note: VMware Virtual SAN is a fully supported feature of vSphere 5.5u1. You can use Virtual SAN in production environments with vSphere Replication 5.5.1 and vSphere 5.5u1. Virtual SAN is an experimental feature in vSphere 5.5. You can perform testing with Virtual SAN with vSphere Replication 5.5.0 and vSphere 5.5, but it is not supported for use in production environments. See the release notes for the vSphere Replication 5.5.0 release for information about how to enable Virtual SAN in vSphere 5.5.
vSphere Distributed Power Management	Yes	vSphere Replication coexists with DPM on the source site. vSphere Replication does not perform any special DPM handling on the source site. Disable DPM on the target site to allow enough hosts as replication targets.
VMware vSphere Flash Read Cache	Yes	You can protect virtual machines that contain disks that use VMware vSphere Flash Read Cache storage. Since the host to which a virtual machine recovers might not be configured for Flash Read Cache, Site Recovery Manager disables Flash Read Cache on disks when it starts the virtual machines on the recovery site. Site Recovery Manager sets the reservation to zero. Before performing a recovery on a virtual machine that is configured to use vSphere Flash Read Cache, take a note of virtual machine's cache reservation from the vSphere Web Client. After the recovery, you can migrate the virtual machine to a host with Flash Read Cache storage and manually restore the original Flash Read Cache setting on the virtual machine.
vCloud APIs	Not applicable	No interaction with vSphere Replication.
vCenter Chargeback	Not applicable	No interaction with vSphere Replication
VMware Data Recovery	Not applicable	No interaction with vSphere Replication.
