hello,

i am a little confused about all the different products and product names.

first netscaler access gateway vpx = citrix access gateway vpx right ?

second when you install cag 5.0.4 vpx the limit is about 50 connections before users will notice some delays. right ?

and last in the interface from the cag i see you can setup high availibility but i do not see any load balanced configuration. now i have read that i need something like a netscaler sollution for this in front of the cag`s..... to get load balancing to work.  is this right ?

What is the difference between the 2 products because some netscaler versions also have cag functionallity ???

help.

Yes, Netscaler Access Gateway VPX = Citrix access gateway VPX. The is the equivalent the the Citrix Access Gateway standard appliance.

The user limit can vary, but a Citrix engineer described it well in this forum. I have definitely seen well over 50 users without a problem.

"A good rule of thumb for AG VPX 5.0 is that it can comfortably support about 250 users per virtual CPU core on XenServer, and about 125 users per core on VMWare. An 8-cpu VPX on XenServer should handle 2000 users."

The HA configuration allows you to create a VIP to represent a pair of Access Gateways, but it is only Active/Passive. You would have to have some sort of hardware load balancer in front of the devices to be active/active. This is not a native functionality.

The Netscaler name may be confusing here. Basically you can get a Netscaler Access Gateway 5.x which provides standard access gateway functionality. A Netscaler ADC 9.x is a Netscaler with advanced functionality, which includes Access Gateway Enterprise.

Mr Black,

You could use a Netscaler 9.x VPX to load balance two Access Gateway standards in theory, but I wouldn't do that.

Personally, I would recommend Netscaler 9.x in almost all cases. The 5.x appliance has been problematic, in my eyes. The are also extra benefits included with the 9.x version, such as load balancing that can used for web interfaces and products outside of Citrix.

I can't really say for sure on the pricing. There are multiple VPX versions available, with limitations on the amount of bandwidth that the device can use.
