Configure SMB Multichannel
 > Example configurations
   > NIC Teaming

Windows Server 2012 R2 and Windows Server 2012 support the ability to combine multiple network adapters into one network adapter by using a feature called NIC Teaming. Although a team always provides fault tolerance, when SMB is deployed without SMB Multichannel, SMB creates only one TCP/IP connection per team. This configuration leads to limitations in both the number of CPU cores that are engaged and the maximum use of the team bandwidth.(수정: 해당 문단은 multichannel을 사용 안할 경우이네요: 답변 감사드립니다.)

When SMB is deployed with SMB Multichannel, SMB creates multiple TCP/IP connections for a single session to achieve a better balance across CPU cores and better use of the available bandwidth. NIC Teaming continues to offer the failover capability, which works faster than using SMB Multichannel by itself. We also recommend NIC Teaming because it offers failover capabilities to other workloads that do not rely on SMB, because those workloads cannot benefit from the failover capabilities of SMB Multichannel.


CPU Core수에 제한된다고 MS가 아주 못박아놨습니다. ㅜㅜ..
내일 가서 팀을 재구성해야겠어요.


혹시 티밍과 SMB-Multichannel을 함께 쓰실 계획이신 분들께 제 경험이 도움이 되기를 바라며...
