VMware vnetworking NIC组合和故障转移建议

以下显示了VSPHERE 5.5中当前可用的可用负载式平板选项以及针对虚拟分布式开关（VDS）和虚拟标准开关（VSS）的Nutanix环境的建议配置。
NIC团队和故障转移建议
该主题已关闭以供评论
我们在VDS 5.5上使用增强的LACP在我们的NX6220上的两个GIG端口上创建一个滞后。您会推荐这种配置吗？如果是这样，您将推荐什么作为平衡滞后界面负载的最佳算法？我相信我们目前正在源IP模式下运行。

随着VSPhere 4.0虚拟分布式开关的引入基于负载的团队（LBT），我认为在我认为NIC团队和负载平衡平衡的其他形式的要求中几乎被淘汰了，这就是为什么在发布我们的VNetwork最佳实践时，这就是为什么包括我自己在内的许多VCDX总结为LBT（BPG中的选项1）应该是我们的建议。
LBT非常好，包括：
1.简单
对开关类型或配置无依赖。LBT和多个VLAN支持所需的标准访问点具有802.1q。
无需设计IP地址范围围绕IP哈希的设计范围以确保IPS的哈希确保流量平衡。
2.性能
LBT检测到> = 75％的NIC利用率，并实时在可用的NIC上动态加载余额VM。
3. LBT与“链接状态”故障转移策略一起工作
在故障转移和故障，链接状态和（如果受物理开关的支持）中，“链接状态跟踪”没有复杂性，请确保在链接故障时确保自动管理所有内容。
总之
我认为，在非常有限的情况下，LACP充其量会提供最小的收益。基于物理NIC负载（LBT）设置的路线可确保在使用VMNIC> 75％的情况下，流量将动态扩展到其他可用的适配器上。由于并不是真正需要这样的LACP，而且对于多个10GB连接，我还没有看到网络所需的环境（真正）需要解决的瓶颈。
如果有瓶颈，则基于物理NIC负载与NIOC结合使用的路线将是一个绝佳的解决方案，而无需LACP的复杂性。
这是我们完整BPG的链接：http://go.nutanix.com/techguide-nutanix-vmwarevspherenetworkingonnutanix_lp.html
非常彻底的解释 - 谢谢！我们将LACP作为以前的刀片技术的自然发展，我们可能会考虑随着我们的群集的发展而迁移到基于负载的团队。

可靠的信息 -
我假设您在该特定端口组中使用A/A端口。我的问题是，为什么故障设置设置为否？根据我的经验，我一直与网络团队配置或合作，以在上行链路端口上使用Portfast利用RSTP。
我在他的博客上也看到了一些有关此事的信息（带有VMKERNEL连接的MGMT端口组），好奇为什么这是选择的配置。

遇到了这个线程，因为我们正在准备一个全新的集群，我们将很快投入生产。是否建议所有端口组（IE Management，CVM，VM）的设置？会欣赏任何见解。
