It's a pretty solid layout if you plan your port needs properly based on NIC density and cabinet size, plus you can cable cleanly to an adjacent cabinet's switch if necessary. > > > > > > > > Juniper claims their switches can do clustering using ethernet > > cabling, yet a cluster behaves as a single-system-image > > configuration-wise.

Yes, up to 10 EX4200 switches can be interconnected into a "Virtual Chassis" using either the rear Virtual Chassis Ports (32 Gbps ingress + 32 Gbps egress for each of the 2 ports) with up to 5-meter VCP cables, or using SFP, XFP or SFP+ fiber links (not sure if it works with copper SFP, but might). You can mix/match each type of interconnection within the same VC.
