QFX5100-48S Juniper Networks QFX5100 48SFP10G Port Ethernet switch Layer 3

Description:
The highly flexible, high-performance Juniper Networks® QFX5100 line of Ethernet switches provides the foundation for today’s and tomorrow’s dynamic data center. As a critical enabler for IT transformation, the data center network supports cloud and softwaredefined networking (SDN) adoption, as well as rapid deployment and delivery of applications. Mission-critical applications, network virtualization, and integrated or scale-out storage are driving the need for more adaptable networks. With its diverse set of deployment options, including fabric, Layer 3, and spine and leaf, the QFX5100 is the universal building block for data center switching architectures, enabling users to easily adapt as requirements change over time.

The QFX5100 line includes 10GbE (fiber and copper) and 40GbE fixed-configuration options with rich Layer 2, Layer 3, and MPLS features. The QFX5100 runs the same reliable, high-performance Juniper Networks Junos® operating system that is used by Juniper Networks EX Series Ethernet Switches, Juniper Networks routers, and Juniper Networks SRX Series Services Gateways, ensuring a consistent implementation and operation of control plane features across the entire Juniper infrastructure. Featuring a built-in Insight Technology capability, the QFX5100 provides valuable performance and troubleshooting data via microburst monitoring and hotspot statistics. The QFX5100 can also be used as a Satellite device in a Junos Fusion fabric architecture, deployed in Juniper’s new Virtual Chassis Fabric switching architecture, and installed in Juniper’s existing Virtual Chassis switching architecture.

QFX5100 Switch Models The QFX5100 line includes four compact 1 U models and one 2U model, each providing wire-speed packet performance, very low latency, and a rich set of Junos OS features. In
addition to a high throughput Packet Forwarding Engine (PFE), the performance ofthe control plane running on all QFX5100 models is further enhanced with a powerful 1.5 GHz dual-core Intel CPU with 8 GB of memory and 32 GB SSD storage.
