Comment 1 for bug 1359331

Here the corrected link to the driver:

Full controller commercial name is
Dynamic Smart Array B320 - with possible additional letters, indicating integrated to motherboard versions, low profile versions etc.

HP does not provide these drivers for Debian/Ubuntu.
We need to check starting from what of the Ubuntu version these drivers are shipped out of the box as a part of OS distribution.
