Juniper Networks EX and QFX Series switching
Campus / Data center
Campus and data center switching, from access layer up to high-density spine.
EX Series covers campus access and aggregation switching; QFX Series is built for data center spine-leaf designs. Both run the same Junos operating system, so the two product lines share a consistent command structure even though they're sized for different jobs.
Which one you need depends on whether you're wiring office floors (EX) or a server room/data center fabric (QFX) — not a matter of picking a bigger model within one line. We confirm which before quoting, the same distinction that matters on Cisco's Catalyst-versus-Nexus split.
- EX Series for campus access and aggregation
- QFX Series for data center spine-leaf designs
- Consistent Junos operating system across the line
Best for: Businesses running their own data center or high-density server room.
