QFX 3500 SAN Ethernet switch

The Juniper QFX3500 QFabric Switches delivers a high-performance, low-latency, feature rich L2 and L3 switch 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 10GbE platform that runs the same Junos OS as other Juniper switches, routers and security platforms, the QFX3500 data center switch also delivers a fabric-ready edge solution for the Juniper Networks QFabric System.

The QFX3500 data center switch offers 63 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 switch is also a standards-based Fibre Channel over Ethernet (FCoE) transit switch and FCoE to Fibre Channel (FCoE-FC) gateway, protecting customer investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures.

When deployed with other components of the Juniper Networks QFabric System, the QFX3500 data center switch, which is manageable by Junos Space, delivers a fabric-ready QFabric 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 multitier networks.
