Room For Improvement

Juniper EX Series Ethernet Switches face challenges with pricing, usability, stability, integration, security, and require better support and documentation.
NVIDIA Mellanox needs improved user-friendliness, better integration, enhanced GUIs, faster support, and occasional bug fixes.
One area that can be improved is the handling of power interruption, as it can cause the platform to crash.
Solution Architect & Services Delivery Manager EMEA at Beyond Technology
Some integration with AI could be a good idea since I heard that Juniper already has systems to deploy AI within the EX device, but I haven't had the opportunity to try that.
Network Engineer at DCI Indonesia
With other OEMs, customers or partners can directly open tech tickets.
Manager Pre Sales at STBL
I think it's okay; it's the best solution for now for AI data centers.

Has provided reliable performance with useful features such as virtual chassis and high port density
The important thing for our use case of Juniper EX Series Ethernet Switches has been reliability, and there are features such as the Virtual Chassis feature, which is one of the things we use. In our case, we use them as core switches in a network that is not very large, and their reliability and the Virtual Chassis feature work well for us. It was one of the reasons we chose it, along with the port density; we are using the 32 port and the 48 port, which work for our needs. Regarding its security features such as MACsec encryption, they are standard and cover what we want; we do not do a lot as they are just Layer 2 switches, but it has standard security features.
Nurudeen Suleiman - PeerSpot reviewer

Automation and integration improve operations efficiently
We wanted to utilize the advanced InfiniBand and Ethernet solutions offered by NVIDIA, but the users are not too familiar with the InfiniBand environment, which is why we are using the Linux Cumulus 5.6, which is usually the normal Ethernet. I am familiar with NVIDIA Mellanox, as I have products from NVIDIA on review here on our website. I use enhanced multi-tenancy features. Currently, within the data center, we have mixtures of both Cisco Nexus switches, NVIDIA switches, and Huawei switches, so eventually, we are changing all the switches to NVIDIA. On a scale of 1-10, I rate NVIDIA Mellanox an eight.

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…
