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 ports in one aggregated group (at 1.2
Gbps per group).
If any of the contributing members of a specific aggregated group
should fail, that member is excluded from the group. The 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 configuration, 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 network to remain alive should any port fail.
