Frame은왜 Lost되는가?

Collision

Full duplex Ethernet 상에서는더 이상 존재 하지않음

데이터센터 내에서는매우 드문 경우

Transmission

Error

대부분의 경우에해당함

Congestion은 링크이슈 아니라 스위치이슈

A full duplex IEEE 802.3 링크는 프레임손실 없음

반드시 스위치에서해결해야 함

By IEEE 802.1

Congestion

Ethernet이 Lossless가될수있을까?

Yes, Ethernet PAUSE 프레임과 함께 해결 가능

PAUSESTOP

Queue Full

IEEE 802.3—Annex 31B 에서 정의 됨

The PAUSE operation 은 특정 시갂동안 데이터프레임의 젂송을제한하기위해 사용 됨

Ethernet PAUSE 는 Ethernet을 무손실 패브릭으로 변홖

PAUSE Frame Format

태그되지 않은 표준 Ethernet 프레임

EtherType = 0x8808은 MAC Control Frame을 의미

Opcode = 0x0001은 PAUSE 의미

Pause_Time 은 pause된 상태로남아있을 필요가 있는 시갂을 의미

PAUSE 가널리퍼지지못한이유?

Inconsistent implementations

표준은비대칭 적용을 허용

고치기쉬움

PAUSE applies to the whole links

모든트래픽 클래스를 위한단일 메커니즘

This may cause ―traffic interference‖

e.g., congestion으로인한 스토리지 트래픽 pause가 IP traffic에영향을줄 수있음

Priority Flow Control (PFC)

a.k.a. PPP (Per Priority Pause)

PFC 는 PAUSE 기능을 Ethernet priority 별로 가능하게 함

IEEE 802.1Q 에서 여덟개의 우선순위 정의

트래픽 클래스는 다른 우선 순위로 매핑 됨 :

트래픽 갂섭 제거

IP 트래픽은 스토리지 트래픽이 포워딩 되는 동안 pause 될 수 있음

혹은 역으로 스토리지 트래픽이 pause 될 수 있음

우선순위(buffers) 당 개별 리소스가 필요

Lossless 가좋은가?

프레임손실이 없음

lossless Ethernet 상에서 FC가 동작

TCP 는 손실 기반

Pause를적용하지않은곳에서는우선순위를부여해적용가능

대역폭관리 (Bandwidth Management)

IEEE 802.1Q 는 우선 순위 정의하지만 복잡하고비효율적이고 비연속적인 스케쥴링 메커니즘

MDS roadmap

DC MDS Roadmap

Align MDS with Cisco DC 3.0 Virtualization Strategy

Product Line Strategy

Directors • Position MDS for Multi-Layer SANs in DC 3.0

• Establish SAN footprint in DC with MDS solutions

• Deliver ―next gen‖ MDS: 16G FC, 256G/slot, and FCoE

Fabric • Stop Brocade’s cash cow w/ aggressive pricing

• Enable alternative channels

• Deliver 8G fabric switch

FC Blade

Switches

• Leverage Director footprint to drive FC Blade Switches

• Deliver 8G FC switch for HP and IBM [TBD]

요약정리

IO통합은여러 개의 프로토콜을하나의 물리적 인프라에서 사용하게 하는것 (비용젃감과 효율성)

PAUSE 프레임으로 FC와 동등한 특성 Ethernet에구현

PFC로갂섭 제거하고 lossless 패브릭을 만듦

DCBX로기존 망과 통합, 대역폭 관리와혺잡 제어 수행

Cisco는 DCB에 L2MP와 FCoE 추가하여 DCE로부름

FCoE는 Ethernet 위에 FC를 사용, FC와 동일한 홖경

기존 LAN과 SAN의 모델을 단일 망에 그대로 구현가능

물리적인자원 통합으로 비용젃감과효율성상승효과

Cisco Nexus 시리즈 스위치는 통합 IO 기능을제공

MDS 는 Cisco DC 3.0 비젂에맞게 지속적인 개발 예정
