1-6DuraLAN Fast Ethernet NICs User’s GuideDuralink64 FailoverDuralink64 Failover software provides protection from network-linkfailures on Fast Ethernet servers running mission-criticalapplications. During a port failure, Duralink64 Failover keeps theconnection to the server live by moving all traffic on the affectedsegment to a backup port. When a failure is detected on the primaryport, that port is disabled and the backup port takes over to continuedata transmission, keeping the connection running withoutinterruption.Duralink64 Failover is often used in a troubled environment toprovide failover capabilities when any of the following conditionsexist:n An Ethernet link lossn A watchdog timer expiresn An abnormal hardware interrupt occursn Abnormal Send/Receive counters, such as too many collisionsor errors occur on the segmentDuralink64 Failover supports Windows NT 4.0 and 3.51, and NovellNetWare 4.x and 5.0 based servers.Duralink64 Failover is compatible with Adaptec ANA™-69011/TXand ANA-62011/TX single-port NICs, ANA-62022 two-port NICs,and ANA-62044 four-port NICs.
