I'm trying to figure out the best way to architect a 2 node fail over cluster with the Hyper V role installed. I can really use some input and suggestions from others who have already been down this road.

All in, I have a 4 physical machines with Datacenter 2019 installed on each. On machine 1 and 2 I have installed 1 VM each and clustered them together as a network load balancer. This work great, no problems here.

On machines 3 and 4 I want to create a Storage Spaces Direct Fail Over Cluster. On these 2 machines I also want to virtualize many services in VM's. Sql Server, A File Server, Email Server etc.

What I am not grasping is as follows. Should I create the Storage Spaces Direct Failover cluster on the Host level or at the Hyper-V VM level? Obviously I need the data replicated across both machines should one machine go down.

I am not sure what the best approach here is.

Thanks in advance.

  • Why the heck do you not make S2D and Hyper-V on the SAME machines? It is fully supported to have a cluster of 4 machines, use S2D for storage and Hyper-V on the same machines - it is called hyperconverged setup. It is even documented - hyperconverged Commented Oct 22, 2020 at 19:50

    I think it would be much easier to create S2D cluster on all 4 hosts. OP iscomplicating. On 2 nodes, of course it is possible to create S2D Failover Cluster, just do not forget about witness drive. techblog.ptschumi.ch/windows-server/storage-spaces-direct/… 4 nodes would be more stable, IMO. Depending on the configuration, S2D alternatives should be considered. As an example: starwindsoftware.com/resource-library/… Commented Oct 25, 2020 at 0:02

Use all of your four servers to host S2D and run VMs.

    I just caught the RTFM part as @NISMO1968 pointed out. I had already implemented my solution with 4 nodes and Hyper-V failover as I had no responses. Pretty much a d*ck statement. I am new to 2sd because I just updated my servers from 2012 to 2019 Datacenter. TomTom in fact I have read the manuals, blog posts, videos etc. for several days before I implemented anything. Lot's of different opinions out there with not a lot of information on real world setups. Hopefully if you ever need help in an unfamiliar technology, people aren't going to make assumptions about your cognitive ability! Commented Oct 26, 2020 at 20:50

    Sorry bud, gen X here.. Not an entitled millennial. I've been writing code for over 30 years. Admin work for me is a necessary bi-product as such. I don't claim to be a guru like yourself, hence the reason I seek help from such well respected condescending purists like yourself. B.T.W. I had already read the article you refer to. MS clearly states that VM's are eligible as an S2d node. Commented Oct 26, 2020 at 22:06

    @th3monk3y you have a point both technically and morally: You can do Storage Spaces inside a Hyper-V VM and... Yes, TomTom is an arrogant D who assumes people owe him only because he bothers to respond with some BS statements to their valid questions. Commented Oct 28, 2020 at 18:21

You can do S2D bare metal only. Storage Spaces (Direct) are unsupported inside the VMs (except Azure, but that’s another story to tell).
