Conventional Core Versus Distributed Core This section describes the differences between a conventional core and a distributed core. Conventional Core A conventional core is a three-tier network that is typically chassis based and is composed of the following: • Core-The core layer routes the traffic to and from the internet and the extranet. Redundancy and resiliency is the main factor for high availability of core routers, which requires chassis-based core routers. • Aggregation layer-The aggregation layer connects with top of rack switches (ToR) and aggregates the traffic into fewer high-density interfaces such as 10GbE or 40GbE. This layer aggregates the traffic to the core layer. • Access layer (ToR)-The access layer typically contains ToRs. A ToR is a small form-factor switch that sits on top of the rack allowing all the servers in the rack to be cabled into the switch. A ToR typically has a small 1 to 2 rack unit (RU) form factor. 7

Introduction
Dell Fabric Manager (DFM) is a graphical user interface (GUI) based network automation and orchestration tool that
allows you design, build, deploy, and optimize a distributed core for your current and future workload requirements. This
tool helps you simplify network operations, automate tasks, and improve efficiency in the data center and campus
environments. DFM supports Dell Z9000 and S4810 switches.
Conventional Core Versus Distributed Core
This section describes the differences between a conventional core and a distributed core.
Conventional Core
A conventional core is a three-tier network that is typically chassis based and is composed of the following:
•
Core—The core layer routes the traffic to and from the internet and the extranet. Redundancy and resiliency is
the main factor for high availability of core routers, which requires chassis-based core routers.
•
Aggregation layer—The aggregation layer connects with top of rack switches (ToR) and aggregates the traffic
into fewer high-density interfaces such as 10GbE or 40GbE. This layer aggregates the traffic to the core layer.
•
Access layer (ToR)—The access layer typically contains ToRs. A ToR is a small form-factor switch that sits on
top of the rack allowing all the servers in the rack to be cabled into the switch. A ToR typically has a small 1 to 2
rack unit (RU) form factor.
