Follow up on Hyper-V High availability? or only VMware

If not for those things, I too would say that StarWind would be overkill.

You did not feel that way in the thread talking about Veeam async replication versus Starwind on VMware in the other thread yesterday. Why do you feel one way there and another here, only because one is a single vendor and the other is always multiple? What is the factor causing the change of opinion since the design and architectures remains constant.

I would be assuming an architectural change, mainly that you would have fewer disks in each host to save on that expense, on the assumption that you had to maintain two servers.

But if all other hardware is staying the same, then sure, absolutely toss StarWind in there. You take a hit on performance, but it's probably one you can afford.

Hardware stays the same. Both approaches require the same doubling of capacity to work. StarWind does not take an exclusive impact on performance, the Hyper-V Replica way sends the same data over the wire, just not in real time. So it takes less of an impacts in latency terms, but the same in throughput, by not getting the data over there in real time.

How will this work with hyper-v clustering? I am still shallow in clustering portion so sorry for any misunderstanding terminology.

All the clustering does is make the licenses move automatically rather than making you do it yourself. For clustering to actually work you need to be licensed for full mobility or you might automate a license violation. But we have done that here, so you are fine.

1 hyper-v core with 2 vms?
during any DR or maintenance the heartbeat will live migrate the VM over to the other host? or...

A live migration can never happen during a DR event by the nature of what a DR event is. That would be like taking a backup after the original data was lost. If you could do that, the original obviously was not lost

1 hyper-v core with 1 vm each.
during any DR or maintenance the heartbeat will boot up the failed VM on its host?

Correct, the data is in both locations at all times.

@scottalanmiller Just a side note.. how can I change the background color from while to black or darker color. white is killing me too bright

Go into your settings and under skin you can change it.

@scottalanmiller apparently only Cyborg works for me. The rest are all white. I'm using chrome.

That's the only one I found that "works" and only barely. I prefer a white text on dark background.

Darkly works for me.

Oh, actually Superhero is really nice. The reply box is still white and funny looking though.
