Introduzione

In questo documento viene fornita una configurazione di esempio per elaborati switch Multilayer Director (MDS) da Fibre Channel over TCP/IP (FCIP) a MDS.

FCIP descrive i meccanismi che consentono l'interconnessione di isole di reti SAN (Storage Area Network) Fibre Channel (FC) su reti IP per formare una SAN unificata in un unico fabric FC. FCIP si basa su servizi di rete IP per fornire la connettività tra le isole SAN su reti LAN, metropolitane o WAN.

Figura 1 - SAN Fibre Channel connesse da FCIP

FCIP utilizza il protocollo TCP (Transmission Control Protocol) sulla porta 3225 come trasporto a livello di rete.

Prerequisiti

Requisiti

Prima di provare questa configurazione, accertarsi di soddisfare i seguenti requisiti:

  • La backbone IP deve essere operativa e fornire la larghezza di banda necessaria per supportare le applicazioni che vengono eseguite sui collegamenti FCIP—questa potrebbe essere una topologia di layer 2 (L2) o di layer 3 (L3).

  • Se si tratta di una topologia L3, i router intermedi o gli switch multilivello devono essere configurati e configurati in modo da inoltrare correttamente il traffico IP tra gli indirizzi IP di origine e destinazione dei tunnel FCIP. Se viene applicato Quality of Service (QoS) o Traffic Shaping a qualsiasi dispositivo di rete nel percorso tra i peer FCIP, è necessario consultare il gestore della rete che amministra l'infrastruttura IP per ottenere i dettagli necessari prima di configurare i parametri e le funzionalità relativi al TCP sui profili FCIP di Multilayer Director Switch (MDS).

  • Gli switch Ethernet adiacenti ai dispositivi MDS devono supportare e essere configurati per il trunking 802.1Q se sul modulo dei servizi IPS (MDS IP Storage) sono configurate sottointerfacce.

Componenti usati

Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:

  • MDS 9509 con IPS Service Module (DS-X9308-SMIP) con versione 1.2.1(2a)

  • MDS 9216 con IPS Service Module (DS-X9308-SMIP) con versione 1.2.1(2a)

  • Catalyst 6509 con software Catalyst OS (CatOS) 7.4(3)

  • Server Win2003 (HPQ Pro-Liant-P4) con HBA LP9K Emulex

  • Array di storage IBM (ESS-2105-F20)

Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.

Convenzioni

Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.

Premesse

La tecnologia FCIP è composta dalle seguenti specifiche:

ANSI T11

  1. FC-SW-2 descrive il funzionamento e l'interazione degli switch FC, incluso E_Port e il funzionamento del fabric.

  2. FC-BB-2 è una mappatura che riguarda l'estensione delle reti a commutazione FC attraverso una backbone di rete TCP e definisce modelli di riferimento che supportano E_Port e B_Port.

Gruppo di lavoro IETF IPS

  1. La tecnologia FC su TCP copre i requisiti TCP/IP per il trasporto dei frame FC su una rete IP.

  2. L'incapsulamento del frame FC definisce il formato comune di incapsulamento della fibra.

L'interconnessione tra due switch SAN o fabric su FCIP è detta collegamento FCIP e può contenere una o più connessioni TCP. Ogni estremità di un collegamento FCIP è associata a una porta E virtuale (VE_port) o a una porta B, a seconda dell'implementazione. FC-BB e FC-BB-2 descrivono le differenze tra entrambi gli approcci. Il modulo dei servizi IPS (DS-X9308-SMIP) supporta entrambe le modalità, ma per impostazione predefinita viene utilizzato VE_Port, che è anche la modalità consigliata se tutti i peer interessati sono moduli DS-X9308-SMIP. In questa topologia di esempio, vengono discussi i parametri FCIP over PortChannels, TCP da configurare e FSF (Special Frame).

Configurazione

In questa sezione vengono presentate le informazioni necessarie per configurare le funzionalità descritte più avanti nel documento.

Sui sistemi MDS è necessario acquisire familiarità con le guide alla configurazione IPS per entrambe le piattaforme. La versione più aggiornata dei manuali è disponibile all'indirizzo Configuring IP Storage (Configurazione dello storage IP) sul sito Cisco.com.

Nota: per ulteriori informazioni sui comandi menzionati in questo documento, usare lo strumento di ricerca dei comandi (solo utenti registrati).

Esempio di rete

Nel documento viene usata questa impostazione di rete:

Figura 2 - Topologia 3

ips8_elaborate_2.gif

La topologia 3 mostra un canale della porta FCIP formato da due singoli tunnel FCIP; le interfacce peer si trovano su un cloud IP. Il cloud IP è compresso in uno switch multilivello (Catalyst 6500) che instrada il traffico dalla subnet A alla subnet C e dalla subnet C alla subnet A (e dalla subnet B alla subnet D e dalla subnet D alla subnet A). Le subnet sono definite come segue:

  • Subnet A: 100.100.100.0/30 - Bison int Gig4/1

  • Subnet B: 100.100.100.4/30 - Bison int Gig4/2

  • Subnet C: 200.200.200.0/30- Canterbury Gig2/1

  • Subnet D: 200.200.200.4/30 - Canterbury Gig2/2

La topologia fornisce una larghezza di banda massima nota di 100 Mbps e una larghezza di banda minima di 100 Mbps, che è il profilo in esecuzione per il traffico IP rilevante attraverso questo cloud IP. La configurazione iniziale mostra gli aspetti del channeling delle porte basato su FCIP e del condizionamento del traffico TCP. Nelle sezioni successive, FSF, Interfacce TCP passive e Timestamp FCIP verranno spiegati più avanti.

!--- Note on TCP Parameters !--- The following TCP parameters can be individually configured per FCIP profile:

bison(config-profile)# tcp ?

cwm Enable congestion window monitoring
keepalive-timeout Set keep alive timeout in sec
max-bandwidth-kbps Configure maximum available path bandwidth in Kbps
max-bandwidth-mbps Configure maximum available path bandwidth in Mbps
max-retransmissions Maximum number of retransmissions
min-retransmit-time Set minimum retransmit time in millisecond
pmtu-enable Enable PMTU Discovery
sack-enable Enable SACK option for TCP
send-buffer-size Send buffer size in KBytes

!--- The CWM parameter default value is 10K and should be left untouched under !--- normal conditions. Congestion window monitoring (CWM) is a way of !--- controlling burstiness after long idle times or loss of Acks.


!--- The keepalive-timeout is the TCP keepalive timeout value and is !--- set to 60 seconds by default, though it can range between 1 and 7200 seconds.


!--- The max- and min-bandwidth parameters program the TCP Maximum Window Size !--- (scaling factor) and engages an internal “shaper” functionality. !--- These values should be carefully chosen and requires understanding of the !--- intermediate network’s end-to-end topology. The default values are to be !--- changed according to the aforementioned requirements. !--- The Round-trip-time can be derived once you have your FCIP tunnel up and !--- running by issuing the following command:

bison# ips measure 200.200.200.1 interface gigabitethernet 4/1

Round trip time is 53 micro seconds (0.05 milliseconds )

!--- Always add an additional margin of at least a few microseconds to this value. !--- The max-retransmissions counter is set to 4 by default. In a healthy network !--- environment, this value should be left unchanged.


!--- The max-retransmission timer is set to 200 milliseconds. If you experience !--- extremely high retransmission counters, this value can be increased; but, !--- in general, changing this parameter is not required unless the RTT is !--- above 200 milliseconds.


!--- The PMTU (Path MTU discovery) is enabled by default. Best practice is to know !--- what is the maximum MTU size supported by all interfaces along the logical !--- path between both peers.


!--- The SACK feature (Selective Acknowledgment) is not enabled by default. !--- Consider enabling it when you have a lot of retransmissions occurring between !--- the two peers. SACK allows selective retransmissions of your window, which is !--- beneficial if larger maximum window sizes are configured and retransmissions !--- occur frequently. It is enabled in this sample configuration; when you do so, !--- make sure that it is enabled at both sides of the link.


!--- The send-buffer-size is the amount of buffers in addition to the TCP window !--- that are allowed to be transmitted out before starting to flow control the FC !--- sources. The default value is set to 0.

!--- The TCP parameters are identical to what is configured on the peering !--- FCIP interfaces. Only in very specific cases should different values be !--- considered, for example, if the return-path(s) are running across a different !--- part of the network or if the application dictates asymmetrical values.

Verifica

Per verificare che la configurazione funzioni correttamente, consultare questa sezione.

Lo strumento Output Interpreter (solo utenti registrati) (OIT) supporta alcuni comandi show. Usare l'OIT per visualizzare un'analisi dell'output del comando show.

  • show interface gig x/y: visualizza lo stato dell'interfaccia Gigabit associata al profilo FCIP.

  • show ips stats tcp int gig x/y : visualizza le statistiche TCP e le connessioni attive per l'interfaccia Gigabit interessata.

  • show ips arp int gig x/y: visualizza tutte le voci ARP (Address Resolution Protocol) per l'interfaccia Gigabit interessata; nell'elenco deve essere presente l'hop o il peer successivo.

  • show ips ip route int gig x/y: visualizza le route specifiche che passano attraverso l'interfaccia Gigabit interessata.

  • show interface fcip x: restituisce lo stato dell'interfaccia FCIP e tutti i dettagli relativi al tunnel FCIP.

  • show profile fcip x: visualizza l'indirizzo IP a cui è associato il profilo e tutti i parametri TCP configurati.

  • show int fcip x counters: consente di verificare la presenza di frame che attraversano il tunnel FCIP.

  • show fcdomain vsan x: visualizza un elenco di tutti i dettagli relativi al dominio. utilizzata per verificare che l'infrastruttura sia in formato nei tunnel FCIP.

  • show fcns da vsan x: visualizza tutti i tipi pwwn, FC4 e FCID della VSAN interessata; utilizzata per verificare che tutte le voci previste siano distribuite sui tunnel FCIP.

Risoluzione dei problemi

Utilizzare questa sezione per risolvere i problemi relativi alla configurazione.

Accertarsi di usare più volte i comandi show per creare una cronologia dei contatori. I contatori che non sono correlati a un point in time e sono raccolti solo una volta sono per lo più inutili.

Utilizzare le configurazioni riportate di seguito per ulteriori operazioni di risoluzione dei problemi.

Please enable NTP with a common time source on both MDS Switches that are on 
either side of the FCIP link

!--- Note that the value specified is in milliseconds and, because a !--- time difference is specified, both ends of the FCIP tunnel must have access !--- to the same clock source through NTP.
