QFabric System

Scalable Fabric Switching System

The QFabric System is composed of multiple components working together as a single switch. It flattens the network to a single tier to provide high-performance, any-to-any connectivity and management simplicity, making it the ideal network foundation for cloud-ready, virtualized data centers.

    Overview

    The QFabric System is composed of multiple components working together as a single switch to provide high-performance, any-to-any connectivity and management simplicity in the data center. The QFabric System flattens the entire data center network to a single tier where all access points are equal, eliminating the effects of network locality and making it the ideal network foundation for cloud-ready, virtualized data centers.

    QFabric is a highly scalable system that improves application performance with low latency and converged services in a non-blocking, lossless architecture that supports Layer 2, Layer 3, and Fibre Channel over Ethernet capabilities.

    QFabric System Components

    • QFabric Nodes, fixed-configuration edge platforms that connect to networked data center devices
    • QFabric Interconnect, a high-speed transport device that connects all QFabric Nodes in a full-mesh topology
    • QFabric Director, which provides control and management services for the full QFabric System

    QFabric System Models

    • QFX3000-M QFabric System, designed for mid–tier, satellite, and containerized data centers, supports up to 768 10GbE ports with average port-to-port latency of 3 microseconds.
    • QFX3000-G QFabric System, designed for large enterprises, service providers, and cloud data centers, supports up to 6,144 10GbE ports with an average port-to-port latency of 5 microseconds.

    Features

    • Scales to 40 Tbps to deliver unprecedented capacity beyond 10GbE at the access layer.
    • Ultra-low Deterministic Latency is ideal for supporting latency-sensitive applications, east-west traffic flows, virtualization, cloud, and other high-performance data center initiatives.
    • Single-Switch Management greatly simplifies data center operations with less complexity and lower power, space, cooling, and operational costs.
    • Carrier-Class Solution requires no downtime for reconfiguration or maintenance.
    • Scales to Thousands of Ports within a single-tier network in a “pay-as-you-grow” model.
    • Incremental Design allows conversion of QFX Series switches from top-of-rack to QFabric devices.
