May 20, 2020 · Traditional three-tier, scale-up design evolves to a spine-and-leaf, scale-out design. The scale-out, spine-and-leaf architecture provides much better redundancy and high availability. For example, with four or eight spines at the spine layer, if one of the spine switches fails, it loses 25 percent or 12.5 percent of the spine layer capacity. The main point to note is that all leaf switches are connected to every available spine switch in the fabric. This architecture means that through only 2 steps ...스파인-리프 아키텍처는 트래픽이 항상 다음 목적지에서 동일한 홉 (hop)만큼 떨어져 있도록 보장하여 지연시간을 단축하고 예측 가능하게 만듦으로써 이를 지원합니다. STP가 더 이상 필요하지 않으므로 용량 또한 향상됩니다.
