Duralink64 v5.x Failover Software Questions
■
What is Duralink64 Failover software?
Duralink64 Failover software is a network device application
that automatically reacts to preserve a network connection when
an Ethernet link fails. Duralink64 Failover supports mission-
critical applications by activating a standby link in the event of
failure, providing increased uptime and maintaining server
availability. The driver establishes an active and a hot-standby
link. Once the active link goes down, the standby link becomes
active. The standby link is activated when the following
conditions occur on the primary link:
– link loss,
– the driver loses contact with the NIC's keep alive mechanism,
– an abnormal hardware interrupt occurs,
– the port becomes unable to transmit for a specified time, or
– abnormal send and receive counters occur, such as too many
collisions or errors on the segment.
■
Which protocols work with Duralink64 Failover?
TCP/IP and NetBEUI under Windows NT and Windows 2000,
and TCP/IP and IPX/SPX under NetWare.
■
Is Duralink64 software interoperable/compatible with other
vendors' NICs and network devices?
Duralink software only works with Adaptec DuraLAN NICs
but is fully interoperable with network devices (such as switches
and hubs) from other vendors.
■
Does Duralink64 Failover work with a switch or a hub?
Duralink64 Failover works with any switch or any hub.
■
How many ports can I configure for the Failover group?
Two ports per Failover group. Within each group, only one port
can be used as the primary or active port, and only one port can
be used as the backup or standby port.
