The QFX5100 line of scalable Layer 2/3 switches—including the 10/40GbE QFX5100 and the 10/40/100GbE QFX5110—is optimised for application delivery and contains a powerful feature set for virtualised data centres.
The QFX5000 series data centre switching platforms provide universal building blocks for multiple fabric architectures. They work with the Juniper mixed 1/10/40/100GbE Virtual Chassis, Virtual Chassis Fabric, and Junos Fusion architectures. The QFX5100 and QFX5110 switches also support open architectures, such as spine and leaf, Layer 3, and Open Clos IP fabrics.
QFX5000 series switches enable high-availability data centre operations by allowing unified in-service software upgrades (ISSU). They also support virtualised network environments, including Juniper Contrail and VMware NSX Layer 2 gateway services.
Seven switch models are available:
- QFX5110-48S, a 10GbE switch with 48 SFP+ ports and four QSFP28 ports that can be configured as 40GbE or 100GbE ports.
- QFX5110-32Q, a 40GbE switch offering 32 QSFP+ ports or 20 QSFP+ ports with four QSFP28 ports.
- QFX5100-48S, a 10GbE switch that offers 48 dual-mode, small form-factor pluggable (SFP and SFP+) transceiver ports and six quad small form-factor pluggable plus (QSFP+) 40GbE ports.
- QFX5100-48T, a 10GbE switch with 48 tri-speed (100 Mbps/1GbE/10GbE) 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 customisable logic for accelerating compute-intensive, latency-sensitive, and mission-critical application processing.
- QFX5100-96S, a 10GbE switch that provides 96 dual-mode SFP and SFP+ ports and eight quad QSFP+ 40GbE ports.
For added flexibility, the QSFP+ ports on both the QFX5000 series switch models can serve as 4x10GbE ports using QSFP+ to SFP+ direct-attach copper (DAC) or QSFP+ to SFP+ fiber splitter cables and optics. Additionally, the QSFP28 ports on the QFX5110 can be configured as 4x10GbE ports using breakout cables, providing additional configuration flexibility.
In converged server-edge access environments, the switches can be deployed as standards-based Fibre Channel-over-Ethernet (FCoE) transit switches, protecting investments in existing data centre aggregation and Fibre Channel storage-area network (SAN) infrastructures.
