NimbostratusNo. of connection on a single IP Address
Hi Everyone,
I have a small query related to the total no. of connections that can be generated to a single VS IP. As we know standard VS has a load balancing pool associated to it so if i have 3 members in a pool each member can handle a total of 64k connections, so a total of 64kx3= total no. of connection that can be served by this pool but the VS has single IP address which means only 64K connection can be accepted by this service at a time. Is my explanation correct or have I missed anything and looking at it as a wrong bottle neck kindly someone explain.
Regards,

Thomas_GobetHi,
The maximum connections number is not linked to the number of members.
It's your BIG-IP which will create the session on server-side, so you'll always have 64k as a maximum per IP.If you want to use as many session as members in your pool allow you, you'll have to define multiple SNAT IPs in your SNAT pool.
TechgeeegThanks for your reply Thomas, but what if the BigIP is installed in inline mode in this situation i don't need SNAT the connection flow will be like the client request comes and hits the VS IP gets load balanced on the pool members by the BIGIP. Now if more than 64K connections hit the VS IP what will happen in this case? Do I need to have multiple Self IP addresses or what so this gets handled?

Your VS listens on a couple IP/port.
So even if you have 70k clients they will always send them to this port.Your problem only occurs if you have to SNAT traffic, if you think on server connections you won't have any problems on ports availability.
The only problem you might have would be on memory (RAM) availability. - Techgeeeg
Thanks for your reply again .....
