MDS에서 MDS로 FCIP를 사용한 정교한 구성
소개
이 문서에서는 MDS에 대한 정교한 FCIP(Fibre Channel Over TCP/IP) MDS(Multilayer Director Switch)를 위한 샘플 컨피그레이션을 제공합니다.
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.
그림 1 - FCIP로 연결된 파이버 채널 SAN 
FCIP는 포트 3225의 TCP(Transmission Control Protocol)를 네트워크 레이어 전송으로 사용합니다.
사전 요구 사항
요구 사항
이 구성을 시도하기 전에 다음 요구 사항을 충족해야 합니다.
-
IP 백본은 작동 중이고 FCIP 링크 전체에서 실행되는 애플리케이션을 지원하는 데 필요한 대역폭을 제공해야 합니다. 이는 레이어 2(L2) 또는 레이어 3(L3) 토폴로지가 될 수 있습니다.
-
L3 토폴로지인 경우 FCIP 터널의 소스 및 대상 IP 주소 간에 IP 트래픽을 적절하게 전달하도록 중간 라우터 또는 멀티레이어 스위치를 설정하고 구성해야 합니다.QoS(Quality of Service) 또는 트래픽 셰이핑이 FCIP 피어 간 경로의 네트워크 디바이스에서 실행되는 경우 IP 인프라를 관리하는 네트워크 관리자에게 문의하여 MDS(Multilayer Director Switch) FCIP 프로필에서 TCP 관련 매개변수 및 기능을 구성하기 전에 필요한 세부 정보를 얻어야 합니다.
-
MDS와 인접한 이더넷 스위치는 MDS IPS(IP Storage) 서비스 모듈에 하위 인터페이스가 구성된 경우 802.1Q 트렁킹을 지원하고 구성해야 합니다.
사용되는 구성 요소
이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.
-
버전 1.2.(2a)를 실행하는 IPS 서비스 모듈(DS-X9308-SMIP)이 포함된 MDS 9509
-
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.

문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 표기 규칙을 참고하십시오.
배경 정보
FCIP는 다음 사양으로 구성됩니다.
ANSI T11
-
FC-SW-2는 E_Port 및 패브릭 작동을 포함한 FC 스위치의 작동 및 상호 작용을 설명합니다.
-
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
-
FC over TCP는 IP 네트워크를 통해 FC 프레임을 전송하기 위한 TCP/IP 요구 사항을 다룹니다.
-
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.IPS 서비스 모듈(DS-X9308-SMIP)은 두 모드를 모두 지원하지만 기본값은 VE_Port입니다. 이는 관련된 모든 피어가 DS-X9308-SMIP 모듈인 경우 실행하는 권장 모드이기도 합니다.이 샘플 토폴로지에서는 PortChannels를 통한 FCIP, 구성할 TCP 매개변수 및 FSF(특수 프레임) 구성 매개변수에 대해 설명합니다.
구성
이 섹션에는 이 문서에서 설명하는 기능을 구성하기 위한 정보가 표시됩니다.
MDS에서는 두 플랫폼의 IPS 컨피그레이션 가이드를 숙지해야 합니다.최신 버전의 설명서는 Cisco.com의 IP 스토리지 구성에서 찾을 수 있습니다.

네트워크 다이어그램
이 문서에서는 다음 네트워크 설정을 사용합니다.
그림 2 - 토폴로지 3 
토폴로지 3은 두 개의 개별 FCIP 터널로 구성된 하나의 FCIP 포트 채널을 나타냅니다.피어 인터페이스는 IP 클라우드를 통해 이루어집니다.IP 클라우드는 서브넷 A에서 서브넷 C로, 서브넷 C에서 서브넷 A로, 서브넷 B에서 서브넷 D로, 서브넷 D에서 서브넷 A로 트래픽을 라우팅하는 하나의 멀티레이어 스위치(Catalyst 6500)로 축소됩니다. 서브넷은 다음과 같이 정의됩니다.
-
서브넷 A:100.100.100.0/30 - Elsx int Gig4/1
-
서브넷 B:100.100.100.4/30 - Elsx int Gig4/2
-
서브넷 C:200.200.200.0/30- Canterbury Gig2/1
-
서브넷 D:200.200.200.4/30 - Canterbury Gig2/2
이 토폴로지는 알려진 최대 대역폭 100Mbps와 최소 대역폭 100Mbps를 제공합니다. 이는 이 IP 클라우드를 통한 관련 IP 트래픽에 대해 실행되는 프로필입니다.초기 컨피그레이션은 FCIP 기반 포트 채널링 및 TCP 트래픽 조절 기능을 보여줍니다.다음 섹션에서는 FSF, Passive TCP 인터페이스 및 FCIP Timestamp에 대해 자세히 설명합니다.

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. |

!--- FCIP Time Stamp is enabled to allow the peer to drop FCIP userdata if it !--- exceeds the specified time-difference. The time difference is the maximum !--- value in transit of user data frames between two peer FCIP entities.

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.
