Cisco는 전 세계 사용자에게 다양한 언어로 지원 콘텐츠를 제공하기 위해 기계 번역 기술과 수작업 번역을 병행하여 이 문서를 번역했습니다. 아무리 품질이 높은 기계 번역이라도 전문 번역가의 번역 결과물만큼 정확하지는 않습니다. Cisco Systems, Inc.는 이 같은 번역에 대해 어떠한 책임도 지지 않으며 항상 원본 영문 문서(링크 제공됨)를 참조할 것을 권장합니다.

소개

이 문서에서는 MDS에 대한 기본 FCIP(Fibre Channel Over TCP/IP) MDS(Multilayer Director Switch)에 대한 샘플 컨피그레이션을 제공합니다.

이 샘플 컨피그레이션은 SAN-OS의 1.2 및 1.3 릴리스와 관련이 있습니다.일부 매개변수는 SAN-OS 2.0 릴리스에서 변경됩니다.2.0 SAN-OS 컨피그레이션 가이드 및 릴리스 정보를 참조하십시오.

FCIP는 IP 기반 네트워크를 통해 FC(Fibre Channel) SAN(Storage Area Network)의 섬들을 상호 연결하여 단일 FC 패브릭에서 통합 SAN을 형성하는 메커니즘을 설명합니다.FCIP는 IP 기반 네트워크 서비스에 의존하여 SAN을 통해 로컬 영역 네트워크, 대도시 영역 네트워크 또는 광역 네트워크를 통해 연결합니다.

FCIP로 연결된 파이버 채널 SAN

basic_fcip_mds-a.gif

FCIP는 포트 3225의 TCP(Transmission Control Protocol)를 네트워크 레이어 전송으로 사용합니다.

사전 요구 사항

요구 사항

IP 백본은 FCIP 링크 전체에서 실행되는 애플리케이션을 지원하는 데 필요한 대역폭을 제공하고 작동해야 합니다. 이는 레이어 2(L2) 또는 레이어 3(L3) 토폴로지가 될 수 있습니다.L3인 경우 중간 라우터 또는 멀티레이어 스위치는 FCIP 터널의 소스 및 대상 IP 주소 간에 IP 트래픽을 적절하게 전달하도록 설정 및 구성해야 합니다.FCIP 피어 간 경로의 네트워크 디바이스에서 QoS(Quality of Service) 또는 트래픽 셰이핑이 시행되면 MDS FCIP 프로파일에서 TCP 관련 매개변수 및 기능을 구성하기 전에 IP 인프라를 관리하는 네트워크 관리자에게 필요한 세부 정보를 문의해야 합니다.

사용되는 구성 요소

이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.

  • 버전 1.2.(2a)를 실행하는 MDS 9509(IP 스토리지(IPS) 서비스 모듈(DS-X9308-SMIP) 포함

  • 버전 1.2.(2a)를 실행하는 IPS 서비스 모듈(DS-X9308-SMIP)이 포함된 MDS 9216

  • Emulex LP9K HBA를 사용하는 Win2003 Server(HPQ Pro-Liant-P4)

  • IBM 스토리지 어레이(ESS-2105-F20)

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다.이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다.현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.

표기 규칙

문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 표기 규칙을 참조하십시오.

배경 정보

FCIP는 다음 사양으로 구성됩니다.

ANSI T11

  1. FC-SW-2는 E_Port 및 패브릭 작동을 포함한 FC 스위치의 작동 및 상호 작용을 설명합니다.

  2. FC-BB-2는 TCP 네트워크 백본을 통해 FC 스위치드 네트워크의 확장과 관련된 매핑이며 E_Port 및 B_Port를 지원하는 참조 모델을 정의합니다.

IETF IPS 작업 그룹

  1. FC over TCP는 IP 네트워크를 통해 FC 프레임을 전송하기 위한 TCP/IP 요구 사항을 다룹니다.

  2. FC 프레임 캡슐화는 일반적인 파이버 캡슐화 형식을 정의합니다.

FCIP를 통해 두 SAN 스위치 또는 패브릭 간의 상호 연결을 FCIP 링크라고 하며 하나 이상의 TCP 연결을 포함할 수 있습니다.FCIP 링크의 각 끝은 구현에 따라 가상 E 포트(VE_port) 또는 B_port와 연결됩니다.FC-BB와 FC-BB-2는 두 접근 방식의 차이점을 설명합니다.IP Services 모듈(DS-X9308-SMIP)은 두 가지 모드를 모두 지원하지만, 기본적으로 VE_Port가 사용됩니다. VE_Port는 관련된 모든 피어가 DS-X9308-SMIP 모듈인 경우 실행하는 데 권장되는 모드입니다.MDS 플랫폼의 VE_Port 기능은 TE 포트 기능도 지원하므로 하나의 FCIP 인스턴스에서 여러 VSAN에서 트래픽을 트렁킹할 수 있습니다.

구성

MDS에서는 두 플랫폼의 IPS 컨피그레이션 가이드를 숙지해야 합니다.이 설명서의 최신 버전은 IP 스토리지 구성입니다.

네트워크 다이어그램

이 문서에서는 아래 다이어그램에 표시된 네트워크 설정을 사용합니다.

basic_fcip_mds-b.gif

이 다이어그램은 두 MDS 스위치의 기가비트 이더넷(GE) 인터페이스 간에 추가 네트워킹 장비가 연결되지 않는 일반적인 랩 설정을 보여줍니다.이는 MDS FCIP 설치 중 가장 간단한 형태이며 일반적으로 고객 랩에서 기본 기능을 확인하는 데 사용됩니다.VSAN 600에서 Emulex LightPulse 9000 HBA는 Windows 2003 서버를 Lex라는 MDS9509에 연결하고 Canterbury라는 MDS9216에 연결된 IBM 스토리지 어레이를 Windows 2003 서버용 LUN이 구성된 Canterbury라고 합니다.

에이전트 SAN 테스트 디바이스는 VSAN 601에 두 개의 디바이스를 채우고 FCP가 아닌 상당한 FC-2 백그라운드 트래픽을 생성하는 에뮬레이터로 사용됩니다.이 주변 장치 장비가 추가되어 컨피그레이션을 더욱 현실화하고 두 참여 스위치의 분산 이름 서버에 많은 항목을 입력할 수 있습니다.이 문서의 핵심은 엔드 투 엔드 연결이 아니며 서버 또는 스토리지 어레이의 스크린샷이 포함되지 않습니다.주변 장치 장비는 FCIP에 대해 잘 모르며 두 MDS 간의 EISL 링크가 정상적인 FC 링크를 통해 실행되는 것처럼 작동합니다.

구성

이 문서에서는 아래 표시된 구성을 사용합니다.

!--- Note that Gig4/1 in the default state is configured with an MTU size of !--- 1500 bytes, if the network topology allows for larger end-to-end frame !--- sizes known as jumbo frames. !--- The default value may be changed to a higher value. A good value is !--- 3000 bytes, because this would avoid the fragmentation of full 2048 FC !--- frames into multiple TCP segments. Not all networking equipment can handle !--- jumbo frames, so the default value of 1500 bytes is a conservative !--- approach to avoid connectivity issues while bringing up the FCIP tunnel.
