THE DATA CENTER HAS EVOLVED – BUT NOT THE NETWORK


TRADITIONAL DATA CENTER NETWORK CHALLENGES

Data Center

E W

Performance Spanning Tree disables upto 50% of bandwidth, tiered networks not

optimized for E-W traffic

Scale Requires additional layers and

adds cost & complexity

Management Simplification Every device managed

separately, multiple networks

Traditional Networks: Inefficient, Complex, Costly to Manage

3 Design Principles

Data Plane Rich edge, Simple core Everything is one hop away

Control Plane Federated Intelligence Only way to scale with resilience

•Copper traces inside a switch replaced with 40G Fiber links between Node & Interconnect.

•Out of band control plane network (not shown) connects all nodes/interconnects to the Director

•Director enables QFabric to be managed as 1 switch
