How to achieve over 2 TB/hr network backup with Integrity entry-class servers running HP-UX 11i v3

Monitoring link utilization of APA
When using a network link aggregation such as HP Auto Port Aggregation (APA), HP recommends
initial monitoring of the network traffic on the physical links to ensure the network traffic is being
balanced as expected. To display the inbound and outbound network traffic of individual network
links, you can use tools such as Glance (-l option), the network switch management utility, or your
selected performance measurement utility. Monitor the individual physical network link loads for
both backup and restore operations, and ensure the system and network link aggregation
configurations are balancing the backup/restore data properly across the physical links. Once initial
setup and configuration is completed, occasionally monitor the network link loads to ensure continued
optimal network load balancing and throughput.
For additional information about Auto Port Aggregation (APA) on HP-UX, see the “HP Auto Port
Aggregation Administrator's Guide: HP-UX 11i v3”, available with the following link:

Considering the uniqueness of each backup environment
Every backup environment, including the configured client systems, is unique and might show different
results than presented in this white paper. HP recommends that you perform a similar tuning analysis
and optimization effort with each specific backup environment to determine the most optimal settings
and configuration for that unique environment.
Minimizing the server hardware footprint in the data center
To reduce the backup server hardware footprint, we compared the footprints and performance of two
rx3600 backup servers against one rx6600. Figure 10 shows the footprint of the dual-rx3600
backup server setup relative to a single rx3600 server.
