Introduction 7IntroductionThis document provides basic information about the Dell PowerEdge M I/OAggregator, including how to install the switch in the Dell PowerEdgeM1000e Enclosure and perform the initial configuration.For more detailed information about any of the basic installation steps , refer tothe Dell PowerEdge M1000e Enclosure Owner's Manual on the Dell Supportwebsite at http://support.dell.com/manuals.Product DescriptionThe I/O Aggregator is a zero-touch, layer 2 switch blade with two fixed 40GbEports on the base module and support for two optional plug-in modules. TheAggregator operates in a Dell PowerEdge M1000e chassis, which can supportup to 32 servers and six I/O Aggregator blade switches.The Aggregator runs the Dell Force10 Operating System (FTOS) and auto-configures as an unmanaged switch with bridging and multiplexingfunctionality, which transmits traffic as follows:• GbE/10GbE connections through the midplane to up to 32 server ports inthe chassis• 10GbE connections through uplink ports to top-of-rack (ToR) switches• 40GbE connections through stacking ports to other I/O Aggregators in aswitch stackIn a data center network, the Aggregator functions as a flat layer 2 pass-through switch that interoperates with Dell and third-party ToR devices.The switch supports data center bridging (DCB) features, and providesseamless connectivity for a Fiber Channel over Ethernet (FCoE) server andiSCSI storage data traffic.In its default operational mode, the Aggregator requires no additionalconfiguration; network connectivity for servers in an M1000e chassis isenabled. By simplifying switch configuration and management, theAggregator reduces complexity in a data center network.
