ODK-Aggregate using VirtualBox VM - Size of the HDD space

Hi All.
We are about to start using ODK-Aggregate to help us organize data collected to Maceió City Hall - Civil Defense in Brazil. At the fist start we install a ODK-Aggregate VM on Virtualbox and everything is up and running as spected.
We know that VirtualBox GUI offer us 2T of growing disk space. Is it possible to get more than that for a especific instance of ODK-Aggregate VM box?
Than you in advance.
