HP Auto Port Aggregation (APA) Release Notes for HP-UX 11i v1, 11i v2, and 11i v3 March 2009

3 HP APA Overview for HP-UX 11i v3
This chapter provides information about the HP-UX 11i v3 (B.11.31.30) March 2009 release of
HP Auto Port Aggregation (APA) and LAN Monitor software.
This release of HP APA now supports the creation of failover groups over Internet Protocol over
InfiniBand (IPoIB) interfaces.
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 HP 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.
