    The best feature of Juniper QFX Series Switches is the virtual chassis feature because it's very stable in my experience. Juniper QFX Series Switches have positively impacted my organization because it's very helpful for customer connectivity. We've been using it for customer connections, and it's very stable. We can use it for a long time without any broken devices or errors on the system. It has helped me significantly with my network.

    Technology is good but the price is the only factor
    If you are considering TerraScale you should compare with the competition and determine which product will give them the best efficiency versus price. Efficiency in terms of capacity, or cost per terabyte. That is the only factor. I would rate this solution an 8 out of 10 because of the cost per terabyte.

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

    Pros

    "Juniper QFX Series Switches are very good data center switches, and they are the core part of their fabric."
    "Juniper QFX Series Switches provide a good platform for all of our hardware and are easy to use."
    "I do see a return on investment with Juniper QFX Series Switches because I can use this device for a long time, and it's still very stable until now."
    "It's really easy to replicate rules. It's the one that I've used; it was CLI-based. You can implement a large set of rules with CLI. You can just copy a script and add additional changes to the source and destination on the part. And so it's easy to do large zone-based rules."
    "The QFX series is a good choice for large data centers, particularly for Spine-Leaf architectures."
    "Support is good and customer-friendly"
    "The most valuable features are the VxLAN and the EVPN."
    "I do see a return on investment with Juniper QFX Series Switches because I can use this device for a long time, and it's still very stable until now."

    "There is room for improvement in the pricing model. It is too high."
    "The price could be cheaper."
    "It is very costly."
    "I faced issues with the deployment and upgrade. In the QFX5110 series, features like ISSU and DSSQ should be improved. Upgrades should be smoother."
    More Juniper QFX Series Switches cons

    Juniper
    Force10 TeraScale E-Series leverages a unique three CPU architecture that distributes switching, routing and management functionalities between three distinct processors, ensuring that an attack on one function does not impact the rest of the system. Additionally, by providing separate data and control planes, the TeraScale E-Series also allows network managers to always access the system, even under attack. And with advanced rate limiting algorithms, the TeraScale E-Series is able to prevent traffic floods that could cripple the system.
