AFT, ALB and IPSec functions
The Network Adapter that is mounted in the server as the standard
device has the adapter fault tolerance (AFT) function, adaptive
load balance (ALB) function and IP Security(IPSec) function.
What are the AFT, ALB and IPSec functions?
AFT (Adapter Fault Tolerance)
The AFT function is realized by the primary adapter and second-
ary adapter. Usually only the primary adapter operates, and the
secondary adapter automatically operates when there is some trou-
ble with the primary adapter.
ALB (Adaptive Load Balancing)
The ALB function is realized by two to four network adapters.
When two network adapters are mounted, they provide a broad
transmission band of maximum 2000 Mbps (1000 Mbps × 2) by
balancing transmission data flow. (The reception band width is
1000 Mbps.)
The ALB function supports the AFT function.
