Is this something I can achieve with StarWind?

Hello,

I am searching for a solution on an synchronous active-active replication method in vcenter. VMs are on site 1 and need to be sent to site 2 for a quick RTO if site 1 goes down. Then, when site 1 is back it needs to sync the changes made on site 2 back to site 1. Of course, other backup servcies are in place but a restore and such takes much longer.

The sites are connected ONLY via mpls, so the storage systems do not see each other. So it should work over IP. Both sites have Vcenter and ESXi.

Is this something I can achieve with StarWind?

Thanks!!

Welcome to StarWind Forum!
This could work only if you have a witness on the third site or in the cloud.
VSAN, as any active-active mirroring solution, has strict requirements to network redundancy (see https://www.starwindsoftware.com/system-requirements and https://www.starwindsoftware.com/best-p ... practices/). You could benefit of active-passive replication with Veeam or any competitive solution as I doubt any active-active replication solution fits well in this scenario.
You could deploy VSAN at both sites, use it as storage provider for each and use Veeam to replicate data with minimum gap.
I'd suggest talking to our architects here https://www.starwindsoftware.com/v17-request-live-demo.

Having limited storage visibility, how can you achieve near-instant VM failover between vCenter sites over MPLS? I've used VMware Site Recovery Manager (SRM) leveraging vSphere Replication in similar scenarios. It replicates VMs over IP and automates failover/failback, though initial sync can be bandwidth-intensive. Did anyone else find SRM effective or use alternative replication tools like Zerto?

There are system requirements. For the sake of system stability, the networking must meet them.
Please also refer to the guides under https://www.starwindsoftware.com/resour ... al_papers/ to see how the system is configured. Also, I'd strongly recommend having a call with our techs before investing into the solution.
