Configuración básica de MDS a MDS con FCIP
Contenido
Introducción
Este documento suministra un ejemplo de configuración para Canal de Fibra por TCP/IP (FCIP) básico con Switch de Director de Capas Múltiples (MDS) a MDS.
Esta configuración de ejemplo es relevante para las versiones 1.2 y 1.3 de SAN-OS. Algunos parámetros cambian en la versión 2.0 de SAN-OS. Consulte la guía de configuración de SAN-OS 2.0 y las notas de la versión.
FCIP describe mecanismos que permiten la interconexión de islas de redes de área de almacenamiento (SAN) Fibre Channel (FC) a través de redes basadas en IP para formar una SAN unificada en un único fabric FC. FCIP se basa en servicios de red basados en IP para proporcionar la conectividad entre las islas SAN a través de redes de área local, redes de área metropolitana o redes de área extensa.
SAN de Fibre Channel conectadas por FCIP
FCIP utiliza el protocolo de control de transmisión (TCP) en el puerto 3225 como transporte de capa de red.
Prerequisites
Requirements
La red troncal IP debe estar operativa y ofrecer el ancho de banda necesario para admitir las aplicaciones que se ejecutan en los enlaces FCIP; puede ser una topología de capa 2 (L2) o capa 3 (L3). Si L3, los routers intermedios o los switches multicapa deben configurarse y configurarse para reenviar el tráfico IP entre las direcciones IP de origen y de destino de los túneles FCIP adecuadamente. Si se aplica la calidad de servicio (QoS) o el modelado del tráfico en cualquier dispositivo de red en la ruta entre los pares FCIP, se debe consultar al administrador de red que administra la infraestructura IP para obtener los detalles necesarios antes de configurar cualquier parámetro y función relacionados con TCP en los perfiles FCIP MDS .

Antecedentes
FCIP consta de las siguientes especificaciones:
ANSI T11
-
FC-SW-2 describe el funcionamiento y la interacción de los switches FC, incluidos E_Port y el funcionamiento del fabric.
-
FC-BB-2 es un mapping que se relaciona con la extensión de redes conmutadas FC a través de una red troncal TCP, y define modelos de referencia que soportan E_Port y B_Port.
Grupo de trabajo IETF IPS
-
FC sobre TCP cubre los requisitos TCP/IP para el transporte de tramas FC a través de una red IP.
-
La encapsulación de trama FC define el formato común de encapsulación de fibra.
Una interconexión entre dos switches o fabrics SAN a través de FCIP se denomina link FCIP y puede contener una o más conexiones TCP. Cada extremo de un enlace FCIP se asocia a un puerto E virtual (VE_port) o a un puerto B, según la implementación. FC-BB y FC-BB-2 están describiendo las diferencias entre ambos enfoques. El módulo de servicios IP (DS-X9308-SMIP) admite ambos modos, pero de forma predeterminada es VE_Port, que también es el modo recomendado para ejecutarse si todos los peers relevantes son módulos DS-X9308-SMIP. La funcionalidad VE_Port en las plataformas MDS también admite la funcionalidad de puerto TE, lo que la hace capaz de truncar el tráfico de varios VSAN a través de una instancia FCIP.
Configurar
En MDS, debe familiarizarse con las guías de configuración IPS para ambas plataformas. La versión más actual del manual es Configuración del Almacenamiento IP.
Diagrama de la red
Este documento utiliza la instalación de red que se muestra en el siguiente diagrama.
Este diagrama muestra una configuración de laboratorio típica en la que no hay ningún equipo de red adicional conectado entre ambas interfaces Gigabit Ethernet (GE) de ambos switches MDS. Esta es la forma más sencilla de una instalación de MDS FCIP y se suele utilizar en laboratorios de clientes para verificar la funcionalidad básica. En VSAN 600, el HBA Emulex LightPulse 9000 conecta el servidor de Windows 2003 al MDS9509 llamado Bison, y un arreglo de almacenamiento IBM conectado al MDS9216 llamado Canterbury, donde se configuran LUNs para el servidor Windows 2003.
El dispositivo de prueba SAN de Agilent se utiliza como emulador para rellenar VSAN 601 con dos dispositivos, así como para generar un tráfico en segundo plano FC-2 no FCP sustancial. Este equipo periférico se agrega para hacer la configuración más realista y para tener entradas sustanciales en el servidor de nombres distribuido de ambos switches participantes. El objetivo de este documento no es la conectividad de extremo a extremo, y no se incluyen capturas de pantalla del servidor o de la matriz de almacenamiento. El equipo periférico no conoce el FCIP y se comporta como si el link EISL entre ambos MDS se estuviera ejecutando a través de un link FC normal.
