CSV Direct IO When Using SAS/DAS?

I have set up a very simple POC for a 2-node HyperV cluster sitting on a Dell drive array. I have created a CSV and verified that failover of the VMs works as expected.

I was thinking about CSV and how redirected IO works so I decided to compare SQLIO tests between the coordinator node (the node who owns/controls the volume) and the other node.

I found my performance numbers to be much worse on the non-coordinator node (data server)

My question is - should I expect both nodes in my cluster to have direct IO access when using a DAS/SAS array?

thanks,
Dan
