Overview

HP APA, the HP link aggregation or trunking product, provides the ability to logically group two or more physical network ports into a single Fat Pipe, often called a trunk. 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. This version of HP APA is available for HP-UX 11i v3. For HP-UX 11i v1 and v2, use the HP APA product at HP Auto Port Aggregation - J4240AA.

In addition to increased performance, enterprise users require protection against business interruptions and loss of productivity. HP APA features automatic link failure detection and the ability to transfer traffic to one of the specified redundant links. This is done transparently to the applications to ensure a highly available environment.

March 2014 Release (B.11.31.1403) for HP-UX 11i v3

The March 2014 release mainly contains defect fixes. For more information on this release, see HP Auto Port Aggregation (APA) Release Notes for HP-UX 11i v3.

Features and Benefits

HP APA provides the following key benefits:

  • Bandwidth scalability: Allows scaling of networks to improve aggregate throughput.
  • High availability: Provides redundancy or link aggregation of network ports.
  • Load balancing: Supports load balancing and failure recovery capabilities and distributes traffic evenly across the aggregated links, based on IP, TCP Port, or MAC address.
  • Single MAC address: Assigns one single logical MAC address to an aggregate and all its ports.
  • Flexibility: Allows addition and deletion of ports in an aggregate to achieve desired performance whenever needed.
  • Investment protection: Utilizes Ethernet technology, which provides a natural upgrade path for current Ethernet installations, leveraging existing end-stations, management tools and training.
  • Lower IT costs: Provides automated configuration and management tools using the IEEE 802.3ad or PAgP standards.

HP APA allows the following configuration modes:

  • FEC_AUTO: Used for link aggregates on HP servers that are connected to a switch that supports Cisco's Fast EtherChannel (FEC) protocol, also known as PAgP.
  • LACP_AUTO: Used for link aggregates on HP servers that are connected to a switch that supports IEEE 802.3ad (LACP) protocol.
  • LAN_MONITOR:Used for failover group configuration on HP servers.
