Stacking technology

[Yobaaa]

Hello, I need help:

First question: 

Is it possible to organize the aggregation of ports on the two devices stack technology "Virtual Stacking"? Ie create a trunk  and add the ports 0/0/48 1/0/48. Will provide load balancing?

The second question is: 

What is the essential difference between technology "Virtual stacking" and "IRF Stacking"?

In advance thanks

1. You will need to tell us what switch model you are using.

2. "Virtual stacking" is not stacking. It is management clustering.

"IRF stacking" is 3COM-specific stacking technology which creates a proper single virtual switch out of multiple hardware chassis.
