Duralink64 Failover

Duralink64 Failover software provides protection from network-link

failures on Fast Ethernet servers running miss ion-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 po rt. When a failur e is detected on the prim ary

port, that port is disabled a nd the backup port takes over to cont inue

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 watchdo g timer expires

■An abnormal hardware interrupt occurs

■Abnormal Send/Receive counters, such as too many collisions

or errors occur on the segment

Duralink64 Failo ver supports Windows NT 4.0 and 3.51, and Novell

NetWare 4.x and 5.0 based servers.

Duralink64 Failover is compatible with Adaptec AN A™-69011/TX

and ANA-62011/TX single-port NICs, ANA-62022 two -port NICs,

and ANA-62044 four-port NICs.
