The QFX5100 line of flexible, high-performance, low-latency and feature-rich Layer 2 and Layer 3 switches are optimized for virtualized data center environments. QFX5100 switches are a universal building block for multiple fabric architectures including Juniper’s mixed 1/10/40GbE Virtual Chassis, Virtual Chassis Fabric and QFabric architectures, and open architectures such as Spine and Leaf and Layer 3 fabrics. All QFX5100 switches support In-Service Software Upgrade (ISSU) to deliver hitless data center operations.
QFX5100 switches also include support for virtualized network environments including Juniper Contrail and VMware NSX Layer 2 gateway services.
For added flexibility, the 40GbE ports on the QFX5100 switches can be used as 4x10GbE ports using QSFP+ to SFP+ direct attach copper (DAC) or QSFP+ to SFP+ fiber splitter cables and optics. For converged server edge access environments, the QFX5100 is also a standards-based FCoE transit switch, protecting investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures.
