HP auto-port aggregation software for HP servers-
maximized throughput with enhanced failover protection

In today's enterprise, communication is all about speed and performance. The rapid growth of applications that distribute Internet and intranet information and enable browser-based online transactions mandates ever-faster response times and more efficient Web page access. Today's end users demand that graphically rich Web pages be displayed faster and without patience-trying delays. What's more, client/server applications such as SAP R/3 and database backup require fast, high bandwidth "pipes" into HP 9000 Enterprise Servers.

Along with faster, higher performance, enterprise users also require high availability to protect against business interruptions and loss of productivity. Auto-port aggregation can provide higher-performance server access, an increased level of redundancy, and protection from link outages-with lowered network management complexity, as well.

HP auto-port aggregation provides the following benefits:

  • Bandwidth scalability: network managers can scale their networks to improve aggregate throughput.
  • High Availability: it provides redundancy or link aggregation of computer ports.
  • Load balancing: HP APA supports true load balancing and failure recovery capabilities and distributes traffic evenly across the aggregated links.
  • Single MAC address: because ports aggregated with HP APA share a single, logical MAC address, there is no need to assign individual addresses to aggregated ports.
  • Flexibility: ports can be aggregated to achieve higher performance whenever network congestion occurs.
  • Investment protection: because the HP APA utilizes Ethernet technology, it provides a natural upgrade path for current Ethernet installations, leveraging existing end-stations, management tools and training.

HP APA can be configured in any of four ways:

Manual mode - This mode should be used to configure Link Aggregates on HP UNIX® servers when connected to a switch which only supports manual configuration.

Auto with PAgP - This mode should be used when configuring Link Aggregates on HP UNIX® servers when connected to a switch which supports Cisco's Fast EtherChannel protocol (PAgP).

Auto with LACP- This mode should be used when configuring Link Aggregates on HP UNIX® servers when connected to IEEE 802.3ad (LACP) supported switches.

LAN monitor - This mode should be used when configuring Fail-over groups on HP UNIX® servers.
