Introduction
This collection of white papers provides guidelines for designing and deploying the access and aggregation layers in the data center using Cisco Nexus products.This document covers the following topics:
PortChannel (Chapter 5)
Virtual PortChannels (Chapter 6)
This document is a natural extension of Data Center Design - IP Network Infrastructure published at the following
link: http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/DC_3_0/DC-3_0_IPInfra.html.This document doesn't cover the integration of load balancers and firewalls in the data center, which is described in
the following publications: http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/nx_7000_dc.html and http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/DC_3_0/dc_sec_design.html.Current Environments
Most data centers today have been built using well-known Cisco multilayer topology with core, aggregation, andaccess layers. Typical data centers use the concept of the pod, which is a building block for the access layer of the
data center. A pod may be made of several racks or an entire row of machines.Consolidation
Most data centers are the result of a consolidation process that was facilitated by the availability of bandwidth to
connect remote locations to centralized data centers. During the consolidation process, enterprises and service
providers simplified the network and the storage infrastructure by adopting topologies that take advantage of virtual
local area networks (VLANs) and the virtual storage area network (VSAN) technology.The same process of simplification is currently happening on the computing nodes. It involves both physical
consolidation by means of blade enclosures and server virtualization at the operating system (OS) level, which makes
it possible to run multiple instances of various operating systems on the same physical machine.End of the Row and Top of the Rack
