Review summaries and opinions

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

ROI

Sentiment score
4.9
Upgrading Juniper QFX Series Switches is costly, with potential miscommunication and missed discounts complicating the long-term financial strategy.
Sentiment score
1.0
Users reported time and cost savings from NVIDIA Mellanox, highlighting improved performance, reduced latency, increased efficiency, scalability, and reliability.
The normal ROI customers work with is five years unless there is a major change in technology.
 

Customer Service

Sentiment score
7.3
Juniper QFX Series customer service is professional and effective, but part availability can delay resolution; overall rated 7.5/10.
Sentiment score
7.5
Customers desire multilingual NVIDIA Mellanox support, rating it satisfactory to good, while often relying on peer assistance.
Sometimes parts are not available in stock, then you have to wait for replacement time.
I would assess their technical support as good—not the best, but it is good.
 

Scalability Issues

Sentiment score
7.8
Juniper QFX Series Switches offer high scalability and performance, supporting varied environments and extensive growth without frequent upgrades.
Sentiment score
5.8
NVIDIA Mellanox's scalable leaf and spine architecture efficiently supports network growth for organizations across various sectors.
When building a fabric, you can add multiple leaf switches and multiple spine switches if required.
 

Stability Issues

Sentiment score
7.4
Juniper QFX Switches offer reliable performance and security, with upgrade issues resolved swiftly by responsive support, rated 8/10 stability.
Sentiment score
5.8
Users are satisfied with NVIDIA Mellanox for its reliable performance and stability, with improvements noted over time.
Juniper has better performance than any other networking product as far as performance is concerned in the router area.
I would rate it a seven because the old versions were not stable, but it is becoming stable over time.
 

Room For Improvement

Improving pricing, user interface, and features can enhance the experience and expand Juniper QFX Series Switches' market share.
NVIDIA Mellanox needs improved user-friendliness, better integration, enhanced GUIs, faster support, and occasional bug fixes.
My personal opinion is that if anyone wants to work with a Layer 3 fabric in a data center, they should choose Juniper because working with ACI and APIC is very complex in the Cisco part.
I think it's okay; it's the best solution for now for AI data centers.
 

Setup Cost

Juniper QFX Switches offer better affordability than Cisco or HPE, yet Fortinet excels in cost-effective security solutions with discounts.
NVIDIA Mellanox offers competitive pricing, strong performance, and cost-effective licensing, making it a highly-rated, affordable enterprise solution.
We are a number one, tier-one partner of Juniper. Therefore, we normally get better discounts than with Cisco because we don't have the level one partnership with Cisco.
For its performance, it's cheaper.
 

Valuable Features

Juniper QFX Series Switches excel in VxLAN, feature high port density, low power use, and efficient data center scalability.
NVIDIA Mellanox excels in performance, flexibility, and integration with AI systems, making it ideal for data centers.
They work with EVPN solutions, providing a Layer 3 fabric, which is a very good capability.
The biggest advantage is that the vendor is the only one providing no-drop traffic.

Offers automation capabilities and good customer support
Juniper QFX Series Switches offer several features that contribute to improved efficiency. One key advantage is the automation capabilities. This allows us to automate network configuration and management tasks using scripting languages. In our case, at the bank, we use a script for automation to confirm the switch's scalability in the local data center. We expanded the environment to utilize the environment feature with AWS, creating connections between both data centers. This setup allowed us to extend our operations to another data center in Latin America, using AWS and Juniper together.

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.
