Overview

QFX5100 switches are flexible data center switching platforms that provide a universal building block for multiple fabric architectures, including Juniper’s mixed 1/10/40GbE Virtual Chassis, Virtual Chassis Fabric, Junos Fusion and QFabric® System architectures, as well as open architectures such as Spine and Leaf, Layer 3 and Open Clos IP fabrics. All QFX5100 switches support unified in-service software upgrades (unified ISSU) to deliver hitless data center operations for high availability.

QFX5100 switches also include support for virtualized network environments including Juniper Contrail and VMware NSX Layer 2 gateway services.

Five QFX5100 switch models are available:

  • QFX5100-48S, a 10GbE switch that offers 48 dual-mode, small form-factor pluggable transceiver (SFP and SFP+) ports and six quad small form-factor pluggable plus (QSFP+) 40GbE ports.

  • QFX5100-48T, a 10GbE switch with 48 tri-speed (10GbE/1GbE/100 Mbps) RJ-45 ports and six QSFP+ ports.

  • QFX5100-24Q, a 40GbE switch that supports up to 32 QSFP+ ports.

  • QFX5100-24Q-AA, a high-performance 40GbE switch that supports an FPGA-based 4x40GbE expansion module with customizable logic for accelerating compute-intensive, latency-sensitive, mission-critical application processing.

  • QFX5100-96S, a 10GbE switch that provides 96 dual-mode SFP and SFP+ ports, and eight quad small form-factor pluggable plus (QSFP+) 40GbE ports.

For added flexibility, the 40GbE ports on the QFX5100 switches can serve as 4x10GbE ports, using QSFP+ to SFP+ direct-attach copper (DAC) or QSFP+ to SFP+ fiber splitter cables and optics. In converged server-edge access environments, you can also deploy the QFX5100 as a standards-based Fibre Channel-over-Ethernet (FCoE) transit switch, protecting investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures.

Features

  • Throughput and capacity up to 2.56 Tbps and 1.44 Bpps, respectively, sustain wire-speed switching with low latency and jitter, as well as full Layer 2 and Layer 3 performance.
  • Redundant power and cooling ensure high availability.
  • Separate control and data planes provide maximum system availability.
  • Support for server and network virtualization using large media access control (MAC) tables enables large-scale virtualization deployment in VMware with Juniper Contrail for select models, and Junos Space Network Director for combined networks.
  • Energy efficiency reduces carbon footprint and operational expenses.
