NIC. Drivers are updated regularly on Adaptec’s Web sites,
thereby providing enhanced performance and new features.
Duralink64 Failover
Duralink64 Failover software provides protection from network-
link failures on Fast Ethernet servers running mission-critical
applications. During a port failure, Duralink64 Failover keeps the
connection to the server live by moving all traffic on the affected
segment to a backup port. When a failure is detected on the
primary port, that port is disabled and the backup port takes over
to continue data transmission, keeping the connection running
without interruption.
Duralink64 Failover is often used in a troubled environment to
provide failover capabilities when any of the following conditions
exist:
■
An Ethernet link loss
■
A watchdog timer expires
■
An abnormal hardware interrupt occurs
■
Abnormal send/receive counters, such as too many collisions or
errors occur on the segment
Failover ports can be connected to a hub or switch.
Duralink64 Failover supports NICs with servers running under
Windows NT 4.0, Windows 2000, Windows XP, and
Novell NetWare 4.2, 5.x, and 6.0.
Duralink64 Port Aggregation
The Duralink64 Port Aggregation configuration allows you to
create a virtual port by grouping up to twelve ports together.
Throughput is distributed over the grouped ports. This grouping
distributes the network load by sharing the resources of all ports in
a group. In the Port Aggregation group, one port becomes the
“primary” port and its address is given to the protocol. The
primary port sends and receives data while it’s backup sends data
only. However, the backup port takes over, sending and receiving
data, when the primary port fails. Thus, the group behaves as a
