NIC. Drivers are updated regularly on Adaptec’s Web sites,

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.
