Cisco FabricPath is a Cisco NX-OS software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments. The benefits of Cisco FabricPath include: Minimal commands per switch ease configuration and operation, Autodiscovery simplifies addition of new links and switches, Provision additional network bandwidth without impacting network, Supports one-, two-, or three-tier architectures, VLAN extensibility across the data center.
Juniper 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.The highly scalable QFabric System improves application performance with low latency and converged services in a nonblocking, lossless architecture that supports Layer 2, Layer 3, and Fibre Channel over Ethernet (FCoE) capabilities.
