Failover Solution on a Blade Server

Nicholas Noor_1 — Tue, 11 Dec 2007 18:54:43 GMT

We are seeking to use all 4 ports of the Blader Server. The first two ports on either side connect via datalink layer, but there is only 1 port connecting via network layer.

We have this connected via single cisco switch, but if this switch fails we have no connectivity to the server.

If we connect to another cisco switch using the 4th port, how should we handle redundancy while maintaining connectivity? Do we use a replicator of just connect to the 2nd cisco switch?

Now a single IP address for eth0 that is used will the switch know the connectivity that this NIC port failed and that it takes over the eth1 and the IP address doesn't change?

Eth0 and Eth0 cannot be bound with a single IP I supppose, what is the solution that the same IP remains or is there another way of doing this?
Please mail me.
Thanks

I suppose this could be called Teaming of the NIC ports. I suppose there is a solution to this.
Thanks

You need ethernet channel bonding. Please see:

I worked on Ubuntu instead of Red Hat, got the system to team, it is working, will work on RH systems later.
Thanks
