So I recently acquired 2 PowerConnect 6224 switches for a new VMware environment being built. Each switch has a Stacking module and a 10GE CX4 module. There likely won't be any future PowerConnect switches involved in this environment - these PowerConnect switches will be utilized for VMware/iSCSI communication and LAG'd to a Netgear GS748tp (corporate LAN switch).
I'm trying to figure out the proper/best way to connect the switches together - using either the Stacking module ports or the 10GE CX4 modules or would there be any benefit to using both? I'm not sure I fully understand the difference between these modules?
Also, when choosing either/or method above, I'm assuming I would need both cables (regardless of method chosen Stacking or CX4)?
Switch 1 XG1 -> Switch 2 XG1
Switch 1 XG2 -> Switch 2 XG2
