[H-GEN] Network Failover stuff

[Michael Anthon]

I have been asked today to investigate network redundancy type stuff for 
one of my servers.  The IT bods in our main office (Sydney) are 
rehashing the main routers and DMZ configuration.  The new config will 
have 2 Cisco 3750s.  I need to hook the built in GigE NICs to the 
routers (one each obviously). 

The server is an HP DL380 running Debian.  My initial reaction was to 
look at the NIC bonding stuff but after reading up a bit I'm not sure 
that's the right tool for this job.  The initial idea that was floated 
to me was to do some sort of IP failover thing using heartbeat tests 
over the network.  Ideally they would prefer that I only require one IP 
address (each machine is on it's own /30 subnet, one address for the 
machine and one for the router) but this isn't a strict requirement.

At this stage I'm really just looking for ideas on where to look and 
what sort of approach people would recommend and thought I would fire 
this off while I continue my research.

Cheers,
Michael
