Provides campus switches and access switches that are simple to deploy, but the code isn't stable enough for a leaf and spine design
If we're building a data center and have Juniper, we have hundreds of Juniper switches in a leaf and spine design architecture, and it's horrible. Sometimes after an upgrade, half of the even port can't be detected. They don't recognize third-party SFPs, and now they claim that they don't support that anymore. There are a lot of issues with the hardware and software. Juniper needs to get their code up to par because it isn't stable enough for a leaf and spine design. If you have over 10,000 VMs or Mac addresses, it doesn't scale. I would love Juniper to have more stable features, hardware, and code. We have so many tickets open with Juniper. The switch reboot doesn't detect the port. About 80% of my problems aren't engineering problems, but are Juniper's problems. In comparison, Arista gives me 10% of the problems that Juniper gives me when it comes to hardware and software. It's falling behind compared to Palo Alto because of its features. Juniper's campus switches and data center switches for the leaf and spine design for the overlay and underlay is horrible. I wouldn't recommend that anyone use Juniper fabric, because there are so many problems, issues, and features that aren't supported.

Powerful hardware, reliable performance, and advantageous open-source OS
Mellanox Switches were easier before Nvidia bought Mellanox and then their new version of the operating system changed. They started with Ennui, and now they only use Linux. If they returned to their previous CLI it would be a good option for starters. The new CLI is more difficult to use but more powerful than the older one. It has its advantages.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"In terms of performance, Juniper switches have a more user-friendly interface and more features than Cisco products."
"Juniper Switches' best feature is its flexibility."
"Juniper is the best when it comes to the core layer."
"It's pretty good as compared to other vendors."
"The solution is stable and scalable."
"The scalability is excellent. It's one of the aspects of the solution that is quite good."
"It's easy to use."
"Junos OS is extremely flexible and easy to pick up."
"The most valuable features of Mellanox Switches are the size, power consumption, and the vast amount of features."
"The tool is very configurable because it runs on a Linux operating system."
"It is a very easy-to-use product."
"The most valuable features of this solution are its functionality."
"From what I've been told, a valuable feature of Mellanox switches is they're quite user-friendly."
"The most valuable features of Mellanox Switches are the powerful hardware and the software is open. They're using Linux operating system. You can do and install many things, and it performs well."
 

Cons

"One potential drawback of the Juniper EX Series has been that those without experience using a command-line interface (CLI) may find it intimidating. However, Junos is working on improving this by offering tools, such as Juniper Mist with Wired Assurance and Apstra. Additionally, the graphical user interface (GUI) could be improved as it has been considered lackluster across the board in Junos."
"The configuration could be made simpler."
"Wireless and monitoring definitely could be improved."
"The security features for the product should be more unified for the product regardless of the product model."
"EX switches take too long to boot when we restart them for maintenance. We need to minimize downtime. Another issue is the command line interface. Juniper's commands are different from other switches, so it's hard to remember them."
"Juniper Ethernet Switches' operating systems get corrupted when the power fails. They have to improve this issue. I may have to use a newer version."
"There are multiple areas of improvement in Juniper EX series switches. In terms of speed and pricing, while Juniper provides good quality services, some clients still find the price very high compared to other competitors. Also there is a need for certain features to be enhanced like clear our configuration process which will help to make Juniper switches more stronger. However, there are also multiple challenges including understanding and configuration of certain aspects difficult without assistance. Despite these kinds of challenges, there have been multiple solutions and huge potential of improvement in Juniper."
"Their web GUI interface needs to be a lot better, especially when compared to HP. The command line is good, but you have to know how to get around it. The GUI is clunky and very slow."
"Mellanox Switches were easier before Nvidia bought Mellanox and then their new version of the operating system changed. They started with Ennui, and now they only use Linux. If they returned to their previous CLI it would be a good option for starters. The new CLI is more difficult to use but more powerful than the older one. It has its advantages."
"Mellanox Switches could improve by adding some features that can make it easier for integrating the switches in some managing and monitoring platforms, such as Elastic or similar software for monitoring data with the data center in a more holistic way."
"The scalability is working fine at the moment, but there's always room for improvement. As of right now, I don't know of any improvements to suggest."
"If you compare this solution with Cisco, utilization in Cisco is more popular and it is more friendly."
"The configuration is a bit different from Cisco, and therefore, for me at least, there's a bit of a learning curve."
 

Pricing and Cost Advice

"It is an inexpensive product."
"Relatively affordable per switch."
"This solution is cheaper than Cisco or HP switches."
"The pricing for the support is very high."
"Their prices are competitive and not bad. It is cheaper than Cisco. We have a yearly license."
"Juniper Ethernet Switches' pricing is high, but that's reflected across the market."
"The pricing of Juniper Ethernet Switches compared to equivalent switches from Aruba, Cisco, and others, Juniper Ethernet Switches are priced a little higher. They are approximately 20 to 50 percent higher. When we receive a new range of models, the prices can come down. The price can also vary by region."
"We only pay for support."
"The pricing is very competitive. The licensing costs are fine."
"The price of Mellanox Switches is reasonable compared to other solutions. The price and quality ratio was very good. There is a one-time license purchase that is needed."
"It's an open-source solution."
"There is a license to use the switch ports of Mellanox Switches."

Benefits of Juniper vs Cisco
Both are decent products. I prefer Juniper for the following reasons: 1) Cleaner separation of data plane from control plane. Higher end Cisco devices are better at this but most of the lower end products still seem to be more integrated than I like. 2) The Hierarchical config design means I can…
