Failover Group Using Link Aggregates

Figure 3-8 (page 31) shows a failover group that uses link aggregates as the active and standby devices to increase the network bandwidth through load balancing across the physical links. This configuration has the following characteristics:

You can use any HP APA link aggregate, except Hot Standby, as a device in the failover group.

The standby link does not have to be a link aggregation. It can be a single physical link of the same type as used in the link aggregation.

Dual switches are not required. However, dual switches provide a more reliable network environment by removing the switch as a single point of failure. If two switches are used, there must be a data path between them.

LAN Monitor failover groups using link aggregates are restricted to switches supported by HP APA link aggregates.
