Exchange Active Sync - Number of TCP connections established by the mobile device with ISA/CAS server
lunes, 30 de abril de 2012 9:23
We are having one ISA server 2006 with Exchange Active Sync published. Now we have almost 6000 users syncing in the office hours.
The question here is how I can estimate the maximum number of users that can be synced with Exchange with the current setup with out any performance issue to the ISA server.
I have already done some research and what I understand is... Application having enough ports to establish TCP connections but the constraint here is non-paged memory and this depends on the number of TCP concurrent connections. So I think we can come to a conclusion on the maximum number of users if we can identify the number of connections that a device is going to establish with ISA and ISA with CAS.
Is my understanding correct? if not please correct me J
If yes please help me to come to a conclusion.

No offense, but for 6000 users, I would be looking at adding resilience to your current setup as the priority rather than worrying about performance ;)
A two server HA setup will also natuarally split your current load (and TCP connections) across two servers for better performance anyhow...

Thank you for the post.
I agree with Jason. Capacity planning tool is useful and you may also refer to this blog: http://blogs.technet.com/b/isablog/archive/2010/01/12/hardware-recommendations-for-forefront-tmg-2010.aspx.

Thanks for your response, as I mentioned we are having ISA 2006 not TMG.
If anybody can share the ISA2006 planning tool would be great.
