Would love to know at what point these devices will start to degrade performance on our SA 4000 cluster. Also, is the number higher on an SA 4500 Cluster?
We have a tool designed for the SA4500 which provides some scaling guidance. Keep in mind that Pulse VPN for iPad/Phone acts more like Network Connect vs Pulse for Android which is using core-access instead.
This might provide you at least a "guestimate" based on what you know of the performance delta between SA4000 and SA4500.
I mis-spoke - the above is for the SA6500 and so comparisons are going to be problematic.
Sorry about the mis-direction - early onset senility
Max that could pass through SA 4000 is 1000 sessions just like in SA 4500.
You could increase number of users as per your requirement depending upon the user licenses you purchase.
This is for "Authentication Only" active sync passthrough. I understand the Junos Pulse connection will count against out total number of licenses but the ActiveSync passthrough does not.
Has Juniper done any stress testing to come up with a number of ActiveSync devices that will start to slow down the SA-4000 or cause devices to miss emails?
I've always recommended that you don't go over the number of users the box is rated at. That is what is tested and supported.
So, if you have 500 users licensed, you can have 500 ActiveSync connections.
