Is this extra cable b/t the boxes a "fabric" or "stacking" connector of sorts?
In the application I had in mind, I will be using (2) NICs from each server
using the Intel Pro/1000 ET's VMLB (virtual machine load balancing) feature.
VMLB requires a "stacked switch" to work properly when you distribute the
connections across multiple switches (that is, they must "look" like a single

The vSYS (or whatever the SRX calls them) would work well for my application,
but I just wish it supported more than 20 (and the SRX 650 is very expensive for
just an increase in the # of vSYS).
