86 Red Hat OpenShift and IBM Cloud Paks on IBM Power Systems: Volume 1
– SEA
Network high availability and redundancy with server-side failover solution that is 
based on the SEA failover to provide virtual network redundancy and failover capability. 
The main advantage of a server-side failover solution is that it simplifies the client 
configuration because you need to create only a single virtual Ethernet adapter in the 
client, which is served by two SEAs that are configured in the high availability mode 
(failover configuration) in two Virtual I/O Servers.
It is recommended to aggregate more physical connections that operate as one link. It 
increases network throughput and high availability. It features two basic modes of 
operation: Etherchannel and LACP 802.3ad, also known as port trunking. 
Figure 5-6 shows an example with two VMs (LPARs) with dual Virtual I/O Server 
configuration with SEA on top of LACP (802.3ad) adapter for client LPARs and an 
Etherchannel adapter for VIO Management interface.
