[Linux-cluster] configuration for two hosts directly connected

[Jie Gao]

Hi All

Since logging for GFS seems to be a potential performance bottleneck, I
wonder, in a two-node cluster, if the two nodes are physically directly
connected and traffic between the two nodes are directed to use that
dedicated connection, using an additional interface on each node,
things would improve.

Supposing it will, how do we configure the interfaces on these
machines? Is there any existing documentation for this?

I suppose we would use something like this:

node A: 11.22.33.44
node B: 22.33.44.55

on node A:

route add -host 22.33.44.55 eth1

on node B:

route add -host 11.22.33.44 eth1

Any comment?


Regards,
