The QFX series is a good choice for large data centers, particularly for Spine-Leaf architectures.
Juniper QFX Series Switches are stable and reliable for diverse hardware, ideal for large data centers, especially in Spine-Leaf architectures. Valuable features like VxLAN and EVPN enhance networking capabilities, with easy rule replication via CLI. However, pricing is high and upgrade issues occur, particularly with QFX5110. Enhanced ISSU and DSSQ features could improve upgrades. Customer support is highly regarded but integrating QFX switches presents challenges.
