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

7o# are an administrator in charge o conig#ring an 8S9 ser"er in yo#r company:s prod#ction

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%

.etails o the networking en"ironment incl#de

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

VM and VM0 > the web ser"ers

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%

Storage Concepts

8S9 Ser"er s#pports the ollowing types o storage de"ices!

Local/ Stores iles locally on an internal or e-ternal SCSI de"ice%

Fibre Channel/ Stores iles remotely on a Storage Area Network )SAN,% @e+#ires ;ibre Channel adapters%

iSCSI (hardware initiated/ Stores iles on remote iSCSI storage de"ices% ;iles are accessed o"er TCPIP network #sing hardware>based iSCSI B?As % It (ses

CBAP a#thentication%

iSCSI (software initiated/ Stores iles on remote iSCSI storage de"ices% ;iles are accessed o"er TCPIP network #sing sotware>based iSCSI code in the
