inconsistent datacenter spec. and license for vSphere replication?

Anyone know how well does the replication fit to datacenters that have different specs?

for example,

there are two vSphere 7 datacenters that need to replicate VMs using vSphere replication 8.6.

But one DC uses "vSphere standard" lincense for hosts and vSAN as shared storage, while the other DC utilizes vSphere enterprise plus and a third party storage(e.g. FC/iSCSI shared storage)

is it gonna impact the maximum number of replications and the size of VM(e.g. vCPU & memory)??

 

B.T.W

Does vSphere replication frequently sync data(between source and destination VM) just like how "fault tolerance" works?

@nblr06,

Heterogeneous datacenters are not an issue as the replication is mainly copying data from one side to another, the issues could appear in terms of performance at the time of a failover as the VMs are currently running on vSAN and the performance from the VMFS could be different but you will need to do some tests to see how your applications work.

Now, for the maximum number of replications, it will depend on the Configurations Maximums of vSphere Replication which is not related to vSAN/VMFS (unless you are using vSAN ESA added in vSphere 8).

Regarding your last question, yes, vSphere Replication replicates the data with a minimum RPO o 5 minutes, however this is not synchronic as Fault Tolerance but asynchronic as it cannot be seconds.
