I64 NIC redundancy

Does anyone know if the I64/OpenVMS supports NIC redundancy transparently?
I think Tru64 supports this and that it there is known as NetRAIN.
Linux on Intel Pro/100S NIC's supports this. Intel calls it "adaptive fault tolerance". Basically what I am after is system support for one IP for 2 or more NICs such that each and every end applications need not worry at the application level about fail over from one network path gone bad to a backup path.

Re: I64 NIC redundancy

Welcome the VMS Forum,

You have two options, and you can combine the two for really interesting network diagrams.

FAILsafe IP, described very well at http://h71000.www7.hp.com/openvms/journal/v2/articles/tcpip.html handles TCPIP connections only.

LAN Failover, is described in Chapter 10, Volume 2 of the System Manager's Manual. http://h71000.www7.hp.com/doc/82FINAL/aa-pv5nj-tk/aa-pv5nj-tk.HTMl

You can create FAILsafe IP addresses on LAN failover logical adapters. For true redundancy, you'll also want redundant network equipment.

LAN Failover tends to provide slightly faster failover, but ties up multiple NICs. FailSAFE IP can provide better bandwidth if that's an issue.
