Storage Spaces Direct 2 Node Hyper-V Cluster

Setting up a 2 node Hyper-V cluster without a SAN and plan to use Storage Spaces Direct for my storage.  I have two identical servers in this Hyper-V cluster with a multi disk SSD Raid 5 data array exposed to the OS. I assume S2D will see the 2 Raid 5 arrays on these servers and I will be able to mirror them as a single CSV which I will then put my clustered VMs on. (these two servers will be connected to each other with a 10gb switch)

 

My question is; if VM1 is live on Node1 in this simple 2 node S2D mirror example, will S2D attempt to serve the VM files from the same node or with all the CSV traffic go out to the physical switch regardless?  I understand this gets more complicated with multiple drives scattered across many servers, but are there any optimizations in this 2 node example?

 

Final question - is there a better way that I should be constructing a 2 node Hyper-V cluster with out a SAN?

 

Thanks in advance!
