Juniper Networks QFX3500, 48 SFP+/SFP and 4 QSFP ports (spare) The QFX3500 switch delivers a high-performance, ultra low latency, feature rich L2 and L3 solution for supporting a wide range of deployment scenarios including traditional and virtualized data centers, high-performance computing, network-attached storage, converged server I/O, and cloud computing

Juniper Networks QFX3500, 48 SFP+/SFP and 4 QSFP ports (spare) The QFX3500 switch delivers a high-performance, ultra low latency, feature rich L2 and L3 solution for supporting a wide range of deployment scenarios including traditional and virtualized data centers, high-performance computing, network-attached storage, converged server I/O, and cloud computing. A versatile, compact, high-density 10 GbE platform that runs the same Junos OS as other Juniper switches, routers and security platforms, the QFX3500 also delivers a fabric-ready edge solution for the Juniper Networks QFabric architecture.The QFX3500 offers 48 dual-mode small form-factor pluggable transceiver (SFP+/SFP) ports and four quad small form-factor pluggable plus (QSFP+) ports in a 1 U form factor, delivering feature-rich L2 and L3 connectivity to networked devices such as rack servers, blade servers, storage systems and other switches in highly demanding, high-performance data center environments. For converged server edge access environments, the QFX3500 is also a standards-based Fiber Channel over Ethernet (FCoE) transit switch and FCoE to Fiber Channel (FCoE-FC) gateway, protecting customer investments in existing data center aggregation and Fiber Channel storage area network (SAN) infrastructures.When deployed with other components of the Juniper Networks QFabric architecture, the QFX3500, which is manageable by Junos Space, delivers a fabric-ready QF/node edge solution that contributes to a high-performance, low latency fabric, unleashing the power of the exponential data center for users migrating from traditional multi-tier networks.
