Manager Technical at a tech services company with 11-50 employees

Comprehensive management tools and robust performance drive network efficiency

Juniper QFX Series Switches are very good data center switches, and they are the core part of their fabric. It's a very good solution with excellent performance. They are easy to use and flexible to deploy in any kind of environment. The Juniper QFX Series Switches is not one switch. When building a fabric, multiple switches must be implemented, including spine, leaf, and other components. Regarding working in a data center environment, they are feature-rich. They work with EVPN solutions, providing a Layer 3 fabric, which is a very good capability. AI is not an integral part right now, so it should not be discussed here.
