Dell PowerConnect 5548 Switch and MD3200i SAN

Hi all,

My goal is to create an xcp-ng cluster using 1x PowerEdge C6220 with 3x nodes, 2x Powerconnect 5548 (switch A and B) and 1x Dell PowerVault MD3200i SAN.

The PowerEgde C6220 that I have have 6x RJ45 ports and 4x ports is dedicated to iSCSI.
The plan is to have failover by creating multipath channels where I have 2 port from each server connected to switch A and another 2 ports to switch B so if 1 switch die, i'm still online.
I will also bound 2 port in lacp group for the server internet connection. 1 port in switch A and the other in switch B.

At the moment the switch are in stack mode because I cannot dedicate the switch only for iSCSI.

As far as the cabling is concerne here is what I have done so far(I hope its not too complicated to understand).

sw1 = switch 1
sw2 - switch 2
p = port number
vl = vlan number

The question that I have is this:

1. How many vlan do I need to create?
is it 2 or 4?

2. what port do I need to group?
In my head I think I need 2 vlan but I am not sure

3. how to create the routing for the vlan?

I only have access to the web interface via vpn at the moment because I forgot to setup ssh via serial.

I really hope I can get some help.

Thank you in advance
