Inleiding

iSCSI-stuurprogramma’s van Cisco, die op de server aanwezig zijn, zijn een belangrijk onderdeel van de iSCSI-oplossing. Deze iSCSI-stuurprogramma’s onderscheppen SCSI-opdrachten, kapselen deze in IP-pakketten en richten deze opnieuw naar Cisco SN 5420, Cisco SN 5428, Cisco SN 5428-2 of Cisco MDS/IPS-8. Dit document biedt voorbeeldconfiguraties voor een host met Microsoft Windows XP iSCSI naar MDS/IPS-8.

Voorwaarden

Vereisten

Zorg er voordat u deze configuratie probeert voor dat u aan deze vereisten voldoet:

Voordat u uw iSCSI-configuratie op de MDS 9000 maakt, moet u een iSCSI-stuurprogramma installeren dat compatibel is met uw PC met Microsoft Windows XP. De meest recente versie van Cisco iSCSI-stuurprogramma voor Windows 2000/XP/2003 is te vinden op de pagina Cisco iSCSI-stuurprogramma’s (alleen geregistreerde klanten) op Cisco.com. De naam van het bestand is het versienummer van Cisco iSCSI driver-versie voor Win2k en kan in de tabel op deze pagina worden gevonden.

De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.

Conventies

De term MDS 9000 heeft betrekking op elk product van de Fibre Channel (FC) switch in de MDS 9000-familie (MDS 9506, MDS 9509 of MDS 9216). IPS-blade verwijst naar de IP-opslagservicesmodule.

Raadpleeg Cisco Technical Tips Conventions (Conventies voor technische tips van Cisco) voor meer informatie over documentconventies.

Achtergrondinformatie

De IP Storage module biedt IP-hosts toegang tot Fibre Channel (FC) opslagapparaten. De IP-opslagmodule is DS-X9308-SMIP. Dit biedt transparante SCSI-routing. IP-hosts die gebruik maken van het iSCSI-protocol kunnen op transparante wijze toegang krijgen tot SCSI (FCP)-doelstellingen op het FC-netwerk. De IP-host stuurt SCSI-opdrachten die in iSCSI Protocol Data Units (PDU’s) zijn ingesloten, naar een MDS 9000 IPS-poort via een TCP/IP-verbinding. Op de IP Storage module wordt de connectiviteit geboden in de vorm van Gigabit Ethernet (GE) interfaces die correct worden geconfigureerd. Met de IP-opslagmodule kunt u virtuele iSCSI-doelstellingen maken en deze aan fysieke FC-doelstellingen toewijzen die in de FC SAN beschikbaar zijn. Het stelt de FC-doelen voor aan IP-hosts alsof de fysieke doelwitten lokaal waren gekoppeld.

Voor elke iSCSI-host die toegang tot opslag via de IP-opslagmodule vereist, moet een compatibel iSCSI-stuurprogramma worden geïnstalleerd. Dankzij het iSCSI-protocol kan het iSCSI-stuurprogramma een iSCSI-host verzenden via een IP-netwerk. Vanuit het perspectief van een host-besturingssysteem lijkt het iSCSI-stuurprogramma een SCSI-transportstuurprogramma te zijn, vergelijkbaar met een FC-stuurprogramma voor een perifeer kanaal in de host. Vanuit het perspectief van het opslagapparaat, verschijnt elke IP-host als een FC-host.

Routing SCSI van de IP-host naar het FC-opslagapparaat bestaat uit deze hoofdacties:

iSCSI-verzoeken en -reacties via een IP-netwerk verzenden tussen hosts en de IP-opslagmodule.
Routing SCSI-verzoeken en reacties tussen hosts op een IP-netwerk en het FC-opslagapparaat (converteren van iSCSI naar FCP en omgekeerd). Dit wordt uitgevoerd door de IP-opslagmodule.
FCP-verzoeken of -reacties verzenden tussen de IP-opslagmodule en FC-opslagapparaten.

De IP-opslagmodule importeert geen FC-doelstellingen standaard voor iSCSI. Ofwel dynamische of statische mapping moet worden geconfigureerd voordat de IP-opslagmodule FC-doelstellingen beschikbaar maakt voor iSCSI-initiators. Wanneer beide zijn ingesteld, hebben de in kaart gebrachte FC-doelen een geconfigureerde naam. In deze configuratie worden voorbeelden van statische mapping gegeven.

Bij dynamische mapping wordt elke keer dat de iSCSI-host zich verbindt met de IP-opslagmodule een nieuwe FC N-poort gecreëerd en kunnen de WWN’s en WWN’s die voor deze N-poort zijn toegewezen, verschillen. Gebruik de statische kaartmethode als u dezelfde WWN's en WWN's voor de iSCSI-host moet verkrijgen telkens wanneer deze met de IP-opslagmodule wordt verbonden. Statische mapping kan op de IP-opslagmodule worden gebruikt om toegang te krijgen tot intelligente FC-opslagarrays met toegangscontrole en een Logical Unit Number (LUN)-omzetting/maskering op basis van de WWN's en/of WWN's van de initiator.

U kunt de toegang tot elk statistisch in kaart gebracht iSCSI-doel controleren als u een lijst specificeert van IP-opslagpoorten waarop deze worden geadverteerd, en een lijst met iSCSI-initiators-knoopnamen die toegang tot dit doel hebben. Op FC zoning-gebaseerde toegangscontrole en op iSCSI gebaseerde toegangscontrole zijn de twee mechanismen waardoor toegangscontrole voor iSCSI kan worden geboden. Beide methoden kunnen gelijktijdig worden gebruikt.

iSCSI-detectie vindt plaats wanneer een iSCSI-host een iSCSI-ontdekkingssessie en vragen voor alle iSCSI-doelstellingen maakt. Met de IP-opslagmodule wordt alleen de lijst met iSCSI-doelstellingen teruggegeven die de iSCSI-host mag benaderen op basis van het toegangscontrolebeleid.

iSCSI-sessie wordt gemaakt wanneer een IP-host een iSCSI-sessie initieert. De IP-opslagmodule verifieert of het gespecificeerde iSCSI-doel (in het sessielogverzoek) een statisch in kaart gebracht doel is en, indien dit waar is, controleert u of de iSCSI-knooppunt van de IP-host het doel mag bereiken. Als de IP-host geen toegang heeft, wordt de inlognaam ervan afgewezen.

De IP Storage module maakt dan een FC virtueel N poort (de N poort kan al bestaan) voor deze IP host en doet een FC name server query voor de FCID van het FC target-WWN dat door de IP-host wordt benaderd. Het gebruikt de pWWN van de IP-host virtuele N-poort als de zoekopdracht van de nameserver. Zodoende doet de naamserver een zone-handhavingsvraag voor de pWWN en reageert de query. Als de FCID door de naamserver wordt teruggegeven, wordt de iSCSI-sessie geaccepteerd. Anders wordt de inlogaanvraag afgewezen.
