Old thread, but somehow, missed it.

We dumped our CRS-X's (8-slot) for the Juniper PTX1000 (2U box).

We realized that we didn't really need all of those fan trays, power 
supplies, control planes, fabrics, line cards, forwarding cards, and 
half a rack, just to push a serious amount of traffic.

It helps that one doesn't also need a chassis, nowadays, to carry a good 
number of 100Gbps ports.

Sure, Cisco probably has something of similar size and stature as the 
PTX1000, but given their new path, we couldn't be asked.

That said, as others also did, there are plenty of boxes carrying 
Broadcom's J2 that will do the job, especially if you relegate it to 
just a P function, and don't try to get funky with edge features.
