Have achieved lower costs and gained reliability with some room for better scalability
The security capabilities of Juniper EX Series Ethernet Switches are comparable to other brands, so there are no additional points for Juniper regarding the security systems. I would rate the price of Juniper EX Series Ethernet Switches an eight out of ten. Regarding stability, I would rate Juniper EX Series Ethernet Switches a nine out of ten. I would recommend Juniper EX Series Ethernet Switches to other organizations because it is easy to use, the command is easy to learn, and it is very stable. I chose Juniper as my primary vendor because it is very stable, reliable, and the price is lower than competitors. I am the person who usually does the maintenance alone. In my office, my two colleagues and I are the network engineers directly responsible for the operation of the EX devices. The number of users in my organization who have access to Juniper EX Series Ethernet Switches is around 17 people. Overall, I would rate Juniper EX Series Ethernet Switches an eight out of ten.

"This solution is impeccable."
"We have found the product to be scalable."
"I like the simplicity of it."
"Both Juniper and Cisco switches are interoperable."
"I find Juniper EX Series Ethernet Switches to be flexible and desirable."
"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."
"From what I've been told, a valuable feature of Mellanox switches is they're quite user-friendly."
"It is a very easy-to-use product."
"The most valuable features of this solution are its functionality."
"The biggest advantage is that the vendor is the only one providing no-drop traffic."
"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

"The stability of this solution should be improved."
"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."
"The only issue that we have with Juniper Ethernet Switches is the firmware because it is not stable."
"The stability could be better. We find, for example, Cisco, to be more stable."
"Juniper should consider reducing its pricing."
"The upgrading of the system should be simplified and made faster."
"The security features for the product should be more unified for the product regardless of the product model."
"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."
"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."
"The configuration is a bit different from Cisco, and therefore, for me at least, there's a bit of a learning curve."
"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."
"Sometimes, it can have some bugs from the past if I am an old user. However, it is stable now."
"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."
 

Pricing and Cost Advice

"The pricing is very aggressive."
"Relatively affordable per switch."
"The price of the Juniper EX Series is reasonable. Cisco is a lot more expensive."
"It is an inexpensive product."
"We had a leakage in the support process and decided to end the product's life in order to purchase a new product with support. We did not renew product support as a result."
"Juniper costs less than the competition. As a comparison, Cisco is 33% more."
"Their prices are competitive and not bad. It is cheaper than Cisco. We have a yearly license."
"Juniper Ethernet Switches are a less expensive solution than Cisco Ethernet Switches. There is only a one-time purchase for Juniper Ethernet Switches."
"There is a license to use the switch ports of Mellanox Switches."
"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."
"The pricing is very competitive. The licensing costs are fine."

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…
