Hi,  Unfortunately Aspera is not free, Aspera is licensed software, can be ordered from EMC directly, Trial licenses can be arranged as well if necessary, make sure you engage the EMC sales/presales team to arrange it for you.
Hey,  Is Aspera free on the Isilon NAS?  If so how do we go about activating it? We are still at OneFS 7.0.1.4 & 7.0.2.1  Thank you,  
Aspera for Isilon
