Please Help with VMWare cluster design using Unity 380F . Few questions

Hi all, I don't really know Unity 380F unit, but it was selected as a SAN for a VMware cluster projet. 

We will have a 4 nodes vmware cluster splited in 2 locations (500 m one from the other).

Each side will have 2 ESX nodes with: 2 Fiber channel ports , and one Untity 380F with 4xFc ports (2 for each SP).

I wanted to avoid the use of a FC switch. Can someone confirm if my forseen setup could work? :

One each site, i would like to directly connect the 2 FC ports of each ESXs to 2 FC ports of theire common Unity 380F (so all Untiy 308F FC ports would be used). Then i would like to use "mirrorview"  (i think it called like this) to sync some LUNS from the first Unity 380F to the second distante one using the 2 10 Gbps ports of the Unity itself (throw a couple of Ethernet 10Gbps switch interconnected by optical fiber) .

 

Would this setup work ? Can we use at the same time 2 fiber channel ports directly connected for Esx,  and the 2 10Gbps ports for Unity mirroring ?

That would avoid me do use a Fc switch or additional board.

 

Thanks a lot for help !
