The QFX series is a good choice for large data centers, particularly for Spine-Leaf architectures.
Juniper QFX Series Switches offer a high return on investment and long-term stability. These switches provide a platform for hardware integration, ease of use, VxLAN, and EVPN features for large data centers. CLI supports straightforward rule replication with excellent customer-friendly support. However, pricing is high, upgrades occasionally fail, and QFX5110 features need enhancement. Integration is challenging, with part availability issues causing delays.
