The QFX series is a good choice for large data centers, particularly for Spine-Leaf architectures.
Juniper QFX Series Switches are valued for stability and reliability, offering a robust platform supporting various hardware. Key features include VxLAN and EVPN, ideal for large data centers with Spine-Leaf architectures. While praised for user-friendly support, concerns exist over high pricing, problematic parts availability, and upgrade issues, notably with QFX5110's ISSU and DSSQ. Buyers should consider potential device upgrade setbacks and pricing model improvements.
