Virtual chassis technology enhances connectivity and simplifies management
Juniper EX series switches offer great technology, particularly their Virtual Chassis technology, which is an excellent feature for stacking switches and functions like a single virtual switch. The EX series provides a separation of control, management, and data planes, reducing the attack surface area, ensuring a lesser extent of vulnerability. The PoE budget is commendable, and they manage connectivity effectively.

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

"The most valuable feature is switching on our network."
"I like the VLAN capabilities, and the Junos interface is easy to use."
"Juniper supports all our connectivity infrastructure in our datacenter, supporting optimal availability and performance for services.​"
"The most valuable feature of Juniper Ethernet Switches is the public remote configuration option. If you make a mistake in the configuration you can roll it back to the previous configuration automatically after a set time frame increment, such as five or more minutes. In all the other competitors once you press to enter the new configuration is already written in. You cannot roll it back automatically."
"I would rate this solution a 10 out of 10 for scalability."
"It is easy to configure, and there are three routing switches."
"The solution is certainly scalable."
"The solution is stable and scalable."
"The most valuable features of Mellanox Switches are the size, power consumption, and the vast amount of features."
"The most valuable features of this solution are its functionality."
"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."
"The tool is very configurable because it runs on a Linux operating system."
"It is a very easy-to-use product."
"From what I've been told, a valuable feature of Mellanox switches is they're quite user-friendly."
 

Cons

"The tool should improve its fabric."
"Juniper EX Series Ethernet Switches lack to offer the latest management tools."
"The Virtual Chassis Fabric is kind of complicated to troubleshoot sometimes. On the MPLS side, they're good — they're fine for the pseudo-wires and stuff—but they need more work on the LAN. It is difficult to troubleshoot their LAN technologies like Virtual Chassis."
"They could improve the code, as there are some issues with it."
"Juniper Ethernet Switches' tech support is hard to reach and slow."
"We need to start seeing some kind of AI to assist with some of what we really want to accomplish from a policy standpoint to achieve better efficiency."
"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."
"They could provide better security tools."
"If you compare this solution with Cisco, utilization in Cisco is more popular and it is more friendly."
"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."
"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."
 

Pricing and Cost Advice

"This solution is cheaper than Cisco or HP switches."
"Support prices and licensing scheme need to be improved to allow some features to be purchased at lower costs, for example, RPM​."
"Juniper Ethernet Switches are cheaper than Cisco or HP."
"The pricing for the support is very high."
"Juniper Ethernet Switches could be less expensive. There is not a license needed to use the solution."
"I think the tool's prices are competitive with the vendors."
"If compared to Cisco, this is a well priced solution. Compared to HP, it is a little bit overpriced. Overall, they are priced in the middle compared to competitors."

"It's an open-source solution."
"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."
"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…
