Hello everyone,
I have a need to design a transparently fault resiliant network.
The idea:
[ Server System A ] [ Server System B,C,D,...]
app <-> vmnet0 -->eth0 <--{switchA}--> eth0 <-- vmnet0 <-> app
\->eth1 <--{switchB}--> eth1 <-/
System X's network config
ifconfig eth0 192.168.0.X
ifconfig eth1 192.168.1.X
ifconfig vmnet0 192.168.X.1
The design is 20+ processors connected via a pair of switches (Dual
Network)
The thought is to have a vmnet0 on each server that the server
application
binds to and run OSPF on every computer to handle failed connections
and
potential switch failure. The need is 24/7/365 uptime. My job is to
make the network recovery transparent to the application.
My question is, How do I do this? I think the OSPF handling network
failure part is pretty easy. How do I setup the vmnet0 interface?
I would assume I would use an ethertap device (or is it tun/tap) but I
am not sure. Has anyone done anything close to this?
Thanks,
~Steven
