Cluster nodes

In case you are looking for geeky valentines poetry.
That was something which came to my mind when I was checking up some configuration for my high reliability cluster node XEN setup during last new year.
Figured someone could have use for it:

Let you be my node S and I will be your node D
We will have great reliability
With synced heartbeat process we will track
the data traffic forth and back
With network raid we will be one
and store the data forth and then
if S goes offline, oh no me
I will crash cause I can not be
without my backup HDD
