Nic teaming是在网络层上设置的,一般是在生产网络或者nfs上面使用。典型的设置是一个标准的虚拟机上面绑定了很多端口组(VLAN),然后出口绑定多个物理网卡。与之连接的物理交换机上也需要配置对应的聚合链路。但是注意标准的虚拟交换机是不支持LACP的。 multipath(MPIO) 则是在软件层面上,由VMWARE的PSA框架来管理负载均衡...
LACP原本用于交换机和交换机之间的链路聚合,启用了LACP协议的2台交换机会相互发送LACP的协商报文,当发现2者 之间有多条可用的链路的时候,自动将这些链路组合成一条带宽更大的逻辑链路,从而利用负载均衡来实现加宽交换机间链路带宽的目的。HP的NIC Teaming也支持动态链路聚合,可以实现在HP服务器和支持802.3ad 动态LACP...
Cannot migrate vmkernel management interface to a virtual distributed switch on ESXi 5.0 and 5.5Migrating a VMkernel interface used for the management network between standard vSwitches Enhanced LACP Support on a vSphere 5.5 Distributed Switch
要点:配置IP Hash方式pNIC对端的物理交换机端口,要记得关闭802.3ad LACP和PAgP以减少这些动态协议带来的不必要网络开销,加快链路在failover时的转换速度。 这种方式的缺点是,因为pNIC是连接到同一台物理交换机的,因此存在交换机的单点失败问题。(这和HP SLB的缺点一样,详见拙文《HP NIC Teaming技术探讨》)。此外,...
Read "vSAN Design Considerations: Fast Storage devices vs. Fast Networking" Read "Common vSAN networking questions" NIC Teaming for Redundancy vSAN network traffic uses a single VMkernel port for most configurations. While some load balancing may occur when using LACP/LAG configurations, care should...
MPIO has several benefits over LACP for iSCSI traffic: • Faster I/O path failure detection • The use of multiple paths for storage I/O Less complicated network setup iSCSI multipathing has the following configuration requirements: • The vSphere host must have two or more physical network...
1. Enable LACP feature on both switches. 2. Enable vPC feature on both switches. 3. Configure a unique vPC domain ID, identical on both switches. 4. Configure mutual management IP addresses on both the switches and configure peer-gateway as shown in Figure 27. ...
· All port channels should be configured in LACP active mode Spanning Tree Considerations · The spanning tree priority was not modified. Peer-switch (part of vPC configuration) is enabled which allows both switches to act as root for the VLANs · Loopguard is disabled by default · BPDU ...

If the uplink name is not in a format such as vmnicX, where X is a number, LACP does not work. When you configure the LAG, if a bundle member flaps, a wrong VMkernel observation message might appear for the LAG: Failed Criteria: 0. After a microcode update, sometimes it is ...
