RE: Limit of LVS NAT

We are also using 2 Dell 1850 servers (dual Xeon and 1gb RAM and it is
eating out of his nose) and we are using NAT for, I think, 30 servers.
(Being 24 php-file webservers and 6 static-file webservers). We have spikes
going up to 225mbit/s.
I can't imagine it is a hard limit.

We have not tweaked the configuration, besides adaptive round robin (the
server is telling the director how much weight he can assign).
Changing to LVS-DR should not be a big problem if a problem arises with the
bandwith

Dear All,
   
     Really ultramonkey is working well with RHEL v4 (kernel 2.6.9)  in my
cluster environment.... My question is what's the exteme limit of LVS NAT 
How  many real servers it can support.How much throughput it can deliver.
How much it's connection limit, how can i increase maximum connections.
As i read the document in linuxvirtualserver.org , LVS NAT works fine in
around 20 real servers.
But what would be happened if i add more than 30 real servers in  cluster.
is it hard limit or what ? , because i am using medium range server(dell
poweredge 1850) with Gbit switch , so network  should not be bottleneck.
even director's configuration is dual P-4 2.4 Ghz processor with 4 GB RAM.

To improve the efficiency of director what should i do, like increasing
socket window size , MTU value of NIC ?
Your experience will help me 


Regards
Ritesh Agrawal
