Introduction to Duralink64 Port Aggregation

Servers with Duralink64 Port

Aggregation

A server with Duralink64 Port Aggregation can use up to 12
Adaptec PCI Fast Ethernet po rt s in one aggregated group (at 1.2
Gbps per group).
If any of the contributing members of a specific aggregated group
should fail, tha t member is e xcluded from the group. Th e remaining
ports balance the existing load.

Duralink64 Port Aggregation Example

The illustration below illustrates a server with 12 ports from three
Adaptec ANA-62044 NICs. With this configurat ion, the server has a
cumulative bandwidth of 1.2 Gbps on its single virtual segment (200
Mbps per port). Further, the network segment is fault tolerant,
enabling the n etwork to remain alive sh ould any port fai l.
