Using APA to Build a Screaming Fast Network Server Connection for HP-UX 11i v2 and v3

Outside the Data Center: Server to Router
The Internet server (left) is configured with a 16Gb Gigabit Ethernet link aggregate. The
Intranet server (right) is configured with an 8Mb Fast Ethernet Link Aggregate. Both
Link Aggregates are configured with the IP-based load-balancing algorithm. Also, a
cross router link is used to allow additional Internet access from the Intranet server.
Both servers must use the IP-based load-balancing algorithm, because they both serve
IP-addressed clients via a router. If a MAC-based algorithm were used instead, all traffic
from the server to the switch will flow out on a single link because a single MAC address
would be used for all packets, that being the MAC address of the router.
BENEFITS:
• Increased bandwidth to handle Internet Services, VPN, Streaming Media, and
Interactive Voice and Audio
• Automatic fault detection and recovery for uninterrupted, continuous access to
server applications and data.
