Jacob,
You have the right idea. The question is can the same load balancer pair
serve n clusters own unique ID address
LVS Backup

is this possible?
of course, that's how lvs works! for each ip:port to load balance, you
can pick any number of realservers to balance across.
Would it be better to put a load balancing lvs pair infront of each cluster
(x,y, and z) would it perform poorly?
I understand LVS works well up to about 100 servers
from what i understand, it really depends on your needs. if you have
heavy fwmark usage or are running other processes on the director, then,
yes, it would make sense to have multiple directors. i think lvs is
more limited by bandwidth than anything else.
i've not heard of the 100 server rule though. can anyone back this up?
