Scalable, stable and easy to install, with good tech support
What is our primary use case?
The solution can be used for the enterprise switch when there are production needs or critical areas involved, such as financial institutions.
What needs improvement?
It would be nice if Juniper provided the system integrator with training, similar to that of Cisco. This is very important. People the world over talk about Cisco. I worked for Juniper for approximately two-and-a-half years, from 2011 to 2013. If Juniper would follow the route of Cisco, I believe its market share would increase, as the switches are stable and scalability exists. Absent this, it faces a challenge when going up against such competitors as Cisco. Juniper's market system is driven down by the systems integrators and end users not having familiarity with the systems they use.
As such, there is a need for more training documentation and integration with Cisco.
For how long have I used the solution?
I have been using Juniper QFabric for around five or six years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is definitely scalable.
How are customer service and technical support?
Technical support is definitely good. It's called the JTAC support, which is always good. No problems whatsoever.
How was the initial setup?
Installation is not a problem.
What about the implementation team?
We have a couple of people responsible for the deployment.
Which other solutions did I evaluate?
Cisco is similar to Juniper, which is very easy to manage and problem-free.
What other advice do I have?
I have recommended the solution to the Bank of India and recommend it to everyone else.
The solution can be deployed on-premises when it comes to large enterprises.
The solution is problem-free. I like its stability, performance, everything really.
Stability and security do not pose issues. Juniper is constantly working on new technologies.
I have many customers. Out of 100,000, I would estimate that I have implemented for 50 to 60 percent of them.
I rate Juniper Qfabric as an eight out of ten.

A robust and scalable solution with amazing technical support and a special setup that can detect what is connected
What is our primary use case?
I did one of the projects with a company that purchased the original micro-fabric design, which had two director nodes. It was for InterConneX, and I believe it had 16 link nodes. They had InterConneX between two main locations of their data centers. They used dark fiber with an MPLS network for the backbone, and then they used the QFabric interlinks to be able to basically send their data center layer to the fabric across those MPLS links. QFabric that I've been dealing with for one of my customers is on code 17.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I have been using this solution since its inception in 2013.
What do I think about the stability of the solution?
Stability has been pretty good. There were tripping points over the years, especially because they were among the first ones to introduce a full fabric infrastructure, but they have learned from that. The one that I have used with the 10K series was hands down. It was one of the better fabrics that I have ever used.
What do I think about the scalability of the solution?
It works pretty well in terms of scalability. It goes through 128 nodes with 48 ports a piece. We're talking about 400,000. If you actually upgrade it to a full class infrastructure, instead of just QFabric, it can go up to almost indefinite nodes.
How are customer service and technical support?
I've dealt with J-Tech a lot. J-Tech is amazing. They're quick on the ball. If you've got issues, they're quick to escalate. I've never really seen a major issue that they haven't been able to solve. Of course, there have been hardware issues every now and then, but this is not just for QFabric. This is across their entire infrastructure.
How was the initial setup?
It was rather complex when I built one up as a POC a while ago. In 2019, I played with the new design using the 10K series, and that one was much easier to set up. They have their own special setup that can detect what is connected. When you apply, you only apply to one controller, and the controller sends everything down the pipe, which is really nice.
What's my experience with pricing, setup cost, and licensing?
In terms of price, the QFabric solution is going to be probably in the middle of the road for a fabric solution.
What other advice do I have?
Make sure that you're aware of what you're going to be putting in. It can be tricky at times to understand the architecture, but once you do, it is going to ease your administration a lot because it is a virtual chassis or a virtual fabric. However, you might want to look into maybe only using it as the physical infrastructure of an SD-WAN layer. That way you've got your orchestration that goes on top of it. Typically, that's not what companies do currently, but I think it is a great solution for that physical layer.
I would rate Juniper QFabric about an eight out of ten. It is a pretty good and pretty robust solution.

Highly stable, straightforward CLI, and integrates well
What is our primary use case?
Juniper QFabric is a vendor solution for core switching and routing.
How has it helped my organization?
If you are having issues with congestion in your server backbone, or your network backbone, using a fabric solution helps you solve those issues by creating paths into the switching stack. QFabric works by having only two hops, which means you are only two hopes away from any node at one time because of the interconnected links.
What is most valuable?
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.
Juniper is good with automation, they integrate well with other tools, such as Chef Puppet.
The CLI is as straightforward. I have had no issues with their CLI and they have a lot of information and settings that are exposed that need to be.
What needs improvement?
Juniper has addressed a lot of areas that they needed to improve in the new fabric solutions that they released. They have a new fabric that uses the standard structure. QFabric is a smaller fabric and Juniper has adopted it to create an industry standard. When creating a new fabric they are able to expand beyond what QFabric's limitations were. I believe their limitations were 128 nodes but with the new solution, it has no end to the nodes you have.
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.
The CLI could be a little confusing if you are new to a switching stack, and especially a fabric switching stack. If you do not understand how it is all architected it could be difficult. It is definitely not for beginners. They did their best to keep it simple, such as creating templates but it is such a complicated system that requires very high-level knowledge on entry. You have to understand what you are doing to play with the configuration of QFabric.
For how long have I used the solution?
I have been using the solution for approximately eight years.
What do I think about the stability of the solution?
The solution is highly stable. In the time I have been using the solution I have not had one major issue.
What do I think about the scalability of the solution?
This solution could improve on the nodes available. However, they have increased this in a newer fabric solution.
How are customer service and technical support?
The technical support is amazing. They are responsive and handle cases extremely well.
Probably one of the better technical assistants that I have worked with over the years.
How was the initial setup?
The initial installation is complex. It can also depend on how in-depth your architecture is. For example, are you going to be in layer three or are you just doing layer two? Is it going to handle dynamic routing protocols? If you are staying on layer two, how are you going to handle the subnetting in general? Are you going to be doing broadcasts? It all comes down to the architecture of the network itself.
What's my experience with pricing, setup cost, and licensing?
The price for Juniper QFabric could improve. There are subscription, maintenance, and add-on feature fees. It is not meant for small or medium organizations. If you are looking at a fabric solution, you are going to be working with SE engineers to be able to get the solution in place. If I wanted to purchase it myself, I would never do it, it would not make sense. The use case for what QFabric solves is more for enterprises and ISP companies.
Which other solutions did I evaluate?
When evaluating other solutions Juniper QFabric has more features, functionality, and a solid base.
What other advice do I have?
For those wanting to implement this solution, I would advise them to definitely look at it carefully. Make sure that you understand what your needs are before you go and purchase and when you do work with a Juniper resource to be able to implement it effectively. There is a steep learning curve for this solution, but that is also true for other solutions, such as Cisco Nexus. You will not be able to pick up the knowledge to use this solution in a week.
I rate Juniper QFabric an eight out of ten.
Which deployment model are you using for this solution?
On-premises

Positive
How was the initial setup?
When they completed the deployment back in 2014, they encountered some challenges, particularly when using RJ45 and Power SFPs. This problem wasn't unique to Juniper switches but rather a common issue across various switch platforms. SFPs need to be programmed to work with specific devices. As a service provider, they preferred switches and SFPs to be more interchangeable, but that wasn't always the case. However, by 2014, it seemed like they had resolved this issue, and it's no longer a concern.
What other advice do I have?
I would overall rate Juniper QFabric a nine out of ten.

How are customer service and support?
My experience with support teams in Bangalore and San Francisco was poor, with a significant delay in resolving critical issues, which led to frustration and eventual migration to Cisco equipment. I would rate it as a one out of ten.
How would you rate customer service and support?
Negative
How was the initial setup?
The deployment of QFabric requires effort and skill, especially for engineers accustomed to configuring Cisco devices. Installation time varies based on expertise, taking longer without prior knowledge. Maintenance is not easy and depends on project requirements. Troubleshooting lacks user-friendly tools compared to alternatives like Cisco.
What's my experience with pricing, setup cost, and licensing?
Juniper QFabric is not overly expensive. Licensing is required for certain features like vRRP, but setting up a virtual chassis does not necessitate a separate license.
Which other solutions did I evaluate?
QFabric may be more complex to configure compared to similar solutions from Cisco or other vendors.
What other advice do I have?
QFabric simplified our data center network architecture by reducing configuration complexity compared to Cisco devices. It required fewer CLI commands, making configuration quicker and easier, especially for scalable deployments.
QFabric improved scalability in our data center by simplifying the addition of new switches to existing configurations. The process was straightforward to manage.
Implementing QFabric can affect overall IT infrastructure costs differently based on configuration needs. For small businesses with stable configurations, costs remain unchanged. However, for scalability and expansion, additional configuration and time may increase costs.
My advice for those using Juniper is to ensure staff are well-trained and certified in Juniper technologies, such as JNCIA, JNCIS, JNCIP, or JNCIE. With these skills, you can effectively manage and troubleshoot Juniper solutions, minimizing potential issues and maximizing performance.
Overall, I would rate Juniper QFabric as a seven out of ten.
