Networking Concepts
There are 3 types o Port ! Ser"ice Console Port
Virt#al Machine Port
VM$ernal port
Virt#al Switch ! "Switch detects which "irt#al machines are logically connected to each o its "irt#al ports and #ses that inormation to
orward traic to the correct "irt#al machines%
Port &ro#p! Speciies port conig#ration options s#ch as bandwidth limitations and V'AN tagging policies or each member port%
'abeled networks are properly conig#red only when all port gro#ps #sing the same network label are able to see the same
broadcast traic%

Design a network configuration for an ESX server based on a set of requirements

en"ironment% ;ill in the "irt#al switch layer< indicating port gro#ps and thier policies< and the physical
connection between the ser"er:s physical NIC:s and the e-ternal switches%

VM:s and Application! =eb based applications implemented #sing 3 VM:s arranged as ollows!

VM:s is pro"ided by SAN,
Physical NIC:s ! There are 1 physical adapters< - 44M?PS and 3 &ig 8thernet cards
8thernet networks! There are 0 physical switches and 1 e-ternal 'AN:s< each named to indicate its
p#rpose% A single physical switch is conig#red to handle traic or 3 networks< which are implemented
as V'AN:s% One Physical switch is dedicated to the management 'AN that by company policy m#st be
physially separated rom all networks% The management 'AN is #sed by Virt#ial centre%
