3 Connecting the Array Cables
Afteryouinstallthearrayinarack,youmustconnectthenetworkandpowercablesand,
optionally,theserialcables.
First,reviewthenetworkrecommendationsinMinimum and Recommended Cable
Configurations on page 10.
Thefollowinglistdescribesthegeneralstepsforconnectingthearraytopowerandthenetwork:
1. Connectthepowercables.Donotturnonpowertothearrayatthistime.SeeConnect and
Secure the Power Cables on page 11.
2. Connectthearraytothenetwork.SeeConnect the Array to the Network on page 12.
3. Turnonpowertothearray.SeeTurning On the Array on page 12.
Thefollowingsectionsdescribethesestepsindetail.Aftercompletingthesteps,seeSoftware
Configuration on page 17.
Network Requirements and Recommendations
TheminimumnetworkconfigurationforaPSSeriesarrayconsistsofaconnectionbetween
Ethernet0oneachcontrolmoduleandacomputerconnectedtoanetworkswitch.Toincrease
performanceandavailability,configuremultiplenetworkinterfacesonanarrayandconnect
themtomultipleswitches.
NetworkrecommendationsaredescribedinTable3.Inaddition,alltheusualrulesforproper
networkconfigurationapplytoPSSeriesarrays.Formoreinformationaboutnetwork
requirements,seetheDellEqualLogicConfigurationGuideontheDellTechCenterwebsiteat
en.community.dell.com/techcenter/storage/w/wiki/2639.equallogic-configuration-guide.aspx.
Generalnetworkconfigurationisbeyondthescopeofthismanual.
Table 3: Network Recommendations
Recommendation Description
Switched10GbE
network
Connectarraysandcomputerstoaswitchednetworkandensurethatall
networkconnectionsbetweencomputersandarraysare10GbE.
UseopticalcableswithopticalSFP+plug-inmodules,orcoppercableswith
integratedSFP+modules.10GBASE-TrequiresCat6minimally,butCat6Ais
recommended.
Requiresaswitchwith10GBASE-Tinterfacestousethe10GBASE-Tport,or
anSFP+switchtousetheSFP+port.
Multiplenetwork
connectionsto
differentnetwork
switches
Forincreasedbandwidthandavailability,connecteachcontrolmoduletotwo
differentswitches.
Theswitchesmustbeconnectedusinginterswitchlinksorbystacking
capability.ThelinksmusthavesufficientbandwidthtohandletheiSCSI
traffic.ReviewtheEqualLogicConfigurationGuideforinterswitchlinksizing
recommendations.
Afterconnectingthenetworkinterfaces,usetheGroupManagerGUIorCLIto
assignanIPaddress,netmask,andgatewayaddresstoeachinterface.
9

Recommendation Description
Management
network(optional)
Connectthemanagementportsonbothcontrolmodulestoa10/100Mbps
networkswitchtokeepmanagementtrafficseparatefromiSCSItraffic.
Accesstothegroup
IPaddress(Hosts)
Inamulti-subnetgroup,eachconfigurednetworkinterfaceshouldhaveaccess
tothesubnetonwhichthegroupIPaddressresides.
Forreplication,a
reliable,adequately
sizednetworklink
Foreffectiveandpredictablereplication,thenetworklinkbetweentheprimary
andsecondarygroupsmustbereliableandprovidesufficientbandwidthfor
copyingdata.
Useofspanning-tree
protocol
Ifpossible,donotuseSpanningTreeProtocol(STP)onswitchportsthat
connectendnodes(iSCSIinitiatorsorarraynetworkinterfaces).
IfyoumustuseSTPorRSTP(STPispreferable),enabletheportsettings
(availableonsomeswitches)thatlettheportimmediatelytransitionintoSTP
forwardingstateuponlinkup.Thisfunctionalitycanreducenetwork
interruptionsthatoccurwhendevicesrestart,andshouldbeenabledonlyon
switchportsthatconnectendnodes.
YoucanuseSTPforasingle-cableconnectionbetweenswitchesandtrunking
formulticableconnectionsbetweenswitches.
VLANs TouseDCB(DataCenterBridging),configureswitchestouseVLANsto
separateiSCSISANtrafficfromothernetworktraffic.
DCB
YoumusthaveVLANsenabled.RefertotheDell EqualLogic Group Manager
Administrator's Manual,andtheDellEqualLogic Group Manager
CLI Reference GuideformoreinformationaboutDCB.
Minimum and Recommended Cable
Configurations
Foradualcontrolmodulearray,therecommendedconfigurationistoconnectnetworkcablesto
Ethernet0onbothcontrolmodules,andconnecteachcontrolmoduletoanetworkswitch.
Forhighperformanceandavailability,distributetheconnectionsacrossmultiplenetwork
switches.
Theswitchesmustbeconnectedwithinterswitchlinksthathavesufficientbandwidthtohandle
theiSCSItraffic,orbystackingcapability.Dellrecommendsusingstackingconfigurations
whereverpossible.
Figure6illustratestherecommendednetworkconfigurationalternatives.
Note: DelldoesnotrecommendconnectingboththeSFP+and10GBASE-TEthernetportsat
thesametime.

Connect the Array to the Network
ThePS4210arraymodelincludestwoType19controlmodules.EachType19controlmodule
includestwo10Gbase-Tportsandtwo10GbeSFP+ports.Ofeachpair,oneislabeledEthernet
0andtheotherislabeledEthernet1.
Thecontrolmodulesalsoincludeone10Mb/100MbportlabeledManagement.Themanagement
portcannotcarryiSCSItraffic.Usethemanagementportonlyifyouconfigureamanagement
network.SeetheDell EqualLogic Group Manager Administrator's Manualformoreinformation.
Obtaintheappropriatenumberofcopperoroptical10GbEnetworkcables.
Note: Opticalcablestransmitdatathroughpulsesoflight.Itisveryimportanttoroutealloptical
cableswithnomorethana4-inchbendradiusatanypointbetweenthearrayandtheswitch.
Onefunctioningnetworkconnectionisrequiredforarrayoperation.Multiplenetwork
connectionsarerecommendedforperformanceandhighavailability.SeeMinimum and
Recommended Cable Configurations on page 10foradditionalinformation.
Turning On the Array
Beforeturningonpower,allowsufficienttimeforthearraytoadjusttoambienttemperature(for
example,overnight).
Note: Youcanturnonthepowertoonepowersupplyfirst(eitherone),orbothatthesame
time.
