Juniper QFabric Pros review quotes

The most valuable features of this solution are the fabric backplane having upwards of 160 GB of communication. It is a top-of-the-rack solution where you have your directors sitting in the main area and then you have your nodes expanded out to your multiple cabinets. It has a very good design and could be your server backbone.

The 40 gig backbone InterConneX was valuable for our use case. It is even faster now. QFabric has spine-leaf technology or topology, which basically makes every single hop only one hop away in terms of connecting from one device to another. It is a pretty good and robust solution. It works pretty well in terms of scalability, and their technical support is amazing.

I do not use GUI's very much for switch stacks. I am always in the CLI. However, I do know that Juniper in the past has lacked on their GUI's, but they have been working on it.

They are working on the virtualization of the actual fabric layer. They are moving away from the original spine-leaf design to a different infrastructure. Instead of having three tiers, which was the director of the interconnected nodes, they cut them back, and they still have that kind of structure.
