Data Center Switches are highly-scalable, highly-automated, port-dense programmable layer 2/layer 3 (L2/L3) devices that support modern data centers. Data Center Switches can be classified by where they are deployed in the data center.
Utilization of the Leaf-Spine data center fabric vs. the traditional three-tier network design of core, aggregation and access, is driven by the high-speed, on-demand, large data flows of today’s modern cloud computing and big data solutions. Leaf-Spine is a 2-tier network design that has a distributed core. Data center switches deployed as a “leaf” aggregate traffic from server nodes to the the “spine” switches in the core of the network. The data center switches in the spine layer also perform routing. Data center switches in a leaf-spine configuration will have packets experience only one hop in moving from leaf to a spine.
The Leaf-Spine data center fabric is more adaptable, efficient and scalable to the changing needs of rapidly evolving data centers and is better at handling the increasing amount of east-west traffic in today’s cloud environments.
