QFabric System
The QFabric System delivers the industry’s most scalable, high-performance fabric switching solution that accelerates and simplified the data center with any-to-any connectivity.
Download Network Test Report QFabric Architecture Demo
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.
| Feature | Benefit |
|---|---|
| Architecture scales up to 40 Tbps | Unprecedented capacity beyond 10GbE at the access layer. |
| Ultra-low deterministic latency provides an order of magnitude improvement over traditional network architectures | Ideal for supporting latency-sensitive applications, east-west traffic flows, virtualization, cloud computing, and other high-performance data center initiatives. |
| QFabric architecture creates single switch management, greatly simplifying data center operations | Fewer switches in the data center translates into significantly less complexity and lower power, space, cooling and operational costs. |
| Carrier-class solution with no single point of failure | Requires no downtime for reconfiguration and maintenance, maximizing network availability. |
| Scales from hundreds to thousands of ports within a single-tier network | The QFabric architecture's "pay-as-you-grow" model can scale from a few hundred ports to 6,000 ports within a single-tier network. |
| Incremental growth allows conversion from top-of-rack to QFabric | QFX Series Switches can be introduced into data centers incrementally as top-of-rack devices, interoperating with the current switch infrastructure and then converted to a QFabric Node edge device through a simple software configuration change, allowing transition to a QFabric solution without requiring a wholesale replacement of the existing network. |
