Back to Basics: Load balancing Virtualized Applications

Hi. I found your article very helpful.

 

I just have one question. I am having problems with some testings for different instances in a virtualized environment.

 

I have only one physical device with 7 virtual instances of my application. When I disable one of them in the F5, the rest work just fine. No problems, But when I restart one virtual server or do an IIS reset in one of the, the rest of the instances stop responding and the whole environments goes to the ground.

 

To give you a most detailed insight, the enclosure holding the virtual applications has 4 cables connected directly to my F5 on an tagged trunk etherchannel allowing the vlan for this purpose.

 

I hope you can provide some help.

 

Thanks.
