If you use stackable switches, you can stack across cabinets (up to 3 with 1 meter Cisco 3750 Stackwise), and uplink on the ends. 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. Should allow for very flexible cabling and operations-wise for TOR switches. I have never tried it however.
The Ex4200 can be stacked by the ethernet expansion ports, either 4 x 1G or 2 x 10G. And yes, it behaves as single switch with multiple line cards.
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.
