Juniper QFX5120 Switch
According to Juniper, the QFX5120 series is designed as top-of-rack and leaf switches in the data center and as distribution switches in campus networks. It offers low-latency Layer 2/3 features and EVPN-VXLAN with Layer 3 gateway for virtualized and bare-metal servers.
The four 1 U models cover 25GbE (SFP28), 10GbE copper (RJ45) and 100GbE (QSFP28). Performance reaches up to 6.4 Tbps bidirectional depending on the model, with latency from 800 ns. Power supplies and fans are redundant and hot-swappable, and airflow direction is selectable. The QFX5120-48YM model provides MACsec AES256 on all ports. All models support Virtual Chassis.
We are happy to advise you on project and volume enquiries. On request, DEVACON handles planning, configuration and commissioning.
