Auto Port Aggregation

HP APA is a software product that creates link aggregates, often called "trunks," which provide a logical grouping of two or more physical ports into a single "Fat-Pipe." Network traffic is load balanced across all of the links in the aggregation, which allows you to build large bandwidth logical links into the server that are highly available and completely transparent to the client and server applications.

In addition, HP APA provides automatic link failure detection and recovery, and optional support for load balancing of network traffic across all of the links in the aggregation.

HP APA supports Serviceguard. See the HP Auto Port Aggregation (APA) Administrator's Guide for more information.

Failover Group

HP APA supports the creation of failover groups (link aggregates in LAN_MONITOR mode), providing a failover capability for links. In the event of a link failure, LAN Monitor automatically migrates traffic to an available, standby link (port or link aggregate) in the failover group.
