I am  aiming for 500,000 concurrent connections. Is this possible ? Is there a way to "estimate" the amount of connections ?
Any help would be appreciated.

I am sure there are other ways to do this..

But, I think this should give you started.

Caution: There is one issue..  They use 1000 and not 1024 as the divisor for Megabytes as an example..  However, look at the bottom of the page as there are sample calculations.

if you need to support that much, have you thought about looking at a load balancing solution amongst  multiple identical servers - perhaps through an F5?

yes they are thinking to add a local load balancer and add another server.

Thanks for the link.
Server is connected to a gigabit port on the switch and bandwidth is 5000TB.
Whats the value i should enter at the " Server connection bandwidth      KBps per sec "   ?

do i enter the 1Gigabit = 1,000,000 Kbps ?
