Ubuntu on HPE ProLiant ML350 Gen9

This morning I was trying to install Ubuntu 16.04 LTS Server on a HPE ProLiant ML350 Gen9 (Intel Xeon E5-2620) just bought. It has two HP hard drives HPE 655710-B21 2.5" 1000GB each. But, during the installation process, it complains saying that the HD are not recognised. I tried enabling and disabling the Smart Array, without success. I understand that I need to provide a driver to Ubuntu.

Does anyone know where I can get the right driver? Thanks a bunch for any help.
