The Why and How of Load Sharing for VIOS Shared Ethernet Adapters
Here are some helpful resources on setting up Shared Ethernet Adapters. If you've worked with dual Virtual I/O Servers (VIOS), you've most likely got experience with Shared Ethernet Adapters (SEAs). You can set them up in failover mode or using the more recent load sharing . With failover, the Ethernet adapters on the backup SEA (for example, on VIO server 2) sit idle until there is a planned or unplanned failure on VIOS1's SEA. In other words, SEAs in failover mode is a binary configuration: if SEA on VIOS1 is up, then your physical Ethernet... [More]

Shared Ethernet Adapter: Load Sharing or Virtual Switches?
For network redundancy, you can set up two Shared Ethernet Adapters (SEAs) - one on each Virtual I/O Server (VIOS). The two SEAs work together with one active, the other idle, so the configuration is called failover mode. This is done by a control channel - a heartbeat that works through a virtual ethernet adapter on each SEA. The failover mode is very effective, because it allows you to shut down a single VIOS and automatically have the other SEA on the alternate VIOS take the traffic. With failover mode you can use VLAN tagging, something not... [More]
