Hi Andrzej,

That’s right, you need to enable both Hyper-V hosts as Replica servers.

Hi Ashok,

For migration from VMware to Hyper-V there are a few different options, my suggestion would be Microsoft Virtual Machine Converter. It’s been retired by Microsoft, Altaro covered it here, Microsoft’s announcement of the retirement is here, and it’s available for download here (use this link at your own risk, since Microsoft isn’t offering the tool as a download anymore).
As for testing Hyper-V Replica you can do that in between two physical Hyper-V hosts or even between two “host” VMs in Hyper-V using nested virtualization.

Hi Mohammed,

This is a big question, and there’s not enough context around the details of your environment, so don’t take this answer in a comment in a forum as the only advice you need. However, in my experience, SAN replication is very expensive (first you pay for one SAN, then the second SAN in the DR site, then you pay for the license to do replication between them) but I suspect if you already have it in place, it’s the best technical solution, especially for such a large deployment.
Hyper-V Replica is a very competent solution, if you were considering switching to it at the scale you’re operating at I would suggest managing it with System Center Virtual Machine Manager, and perhaps also use Azure Site Recovery for a “third site” orchestration (your VM data is NOT replicated to Azure, it’s just a location to manage the orchestration of the replication and failover). Note that Hyper-V Replica does NOT failover automatically, it’s not a geo / stretched cluster solution and thus requires manual intervention for failover.

I hope that gives you some insight into your different options.

Hello Nirmal

Thanks for the nice article.

Currently, we are using SAN based replication to replicate the VM workloads(CSVs) from primary to DR site.

Is Hyper-V replica a good alternate option to do the same? Is Hyper-V Replica a true DR solution?

We have close to 1000 VMs spanning across 10 to 12 Hyper-V Clusters .

Kindly advise.

Thanks
Naseer

You wrote ” You configure Hyper-V Primary Server to accept incoming replication!”
Does it mean that I should tick “Enable this computer as Replica server” on Primary Server?
My configuration, on both side, is Windows Server 2012 R2 with Hyper-V role installed.

Thanks for help,
Andrzej

Running SQL in Replica environment requires a little bit planning. You have two options; (1) location of database and log files on a single VHD file, (2) store database and log files on separate VHD files. For 2nd one, you must enable EnableWriteOrderPreservationAcrossDisks as explained in this MS KB: http://support.microsoft.com/kb/956893.

HTH
Thanks!

thanks,

It is not SAN-aware at all and it uses its own engine to implement the “data replication”.

Please check out how Hyper-V Replica works:
http://hub.altaro.com/hyper-v/how-hyper-v-replica-actually-works/

And yes you must add a LUN at DR site!

Thanks!

thank you.
