Hi, Mike
In your concurrent architecture, the rrd databases will have to be start 
from scratch. ie service failover but the data(rrd databases).

AVS for Solaris 10 looks like a promising solution to do disk mirroring over 
tcp/ip (ie, similar to Linux's DRBD).

So the architecture I am looking at for Hobbit server on Solaris 10 is 
SunCluster 3.2 + AVS to
construct a two nodes HB server that can fail over on both hb server and 
data. see R1

Just planning stage... Don't know if it will really work.
Question in my mind so far is , how can I have hb server ip address fail 
over from one router to another ?
