I want to ask one thing about the Linux LVS Solution. I have setup the
LVS-NAT solution, it worked fine but i m having one small issue onto it.
If one of my real server is down,switched-off the Director does not
detect it immediatley as well the connections are not forwarded
immediately to the second Real Server. At times even it is very
difficult to make connection with the Second Real Server.
Depending on your setup this is to be expected.
Is this normal with LVS or there can be some specific configuration
required in this regard?
LVS itself provides no healthcheck facility - it's just a flashy router.
You need to add something to it for the high-availability aspects, some
of which are described here:

The two (apparently, although this is not a scientific analysis!) most
popular are:
