It is important to clarify a common misunderstanding regarding the controller and so-called "license keys."

If you need RAID 5/6 on a P420i, verify if a cache module is installed. If not, buy one (used ones are widely available and inexpensive). If one is installed but RAID 5 still fails, update the controller firmware via the HP Service Pack for ProLiant (SPP). hp smart array p420i license key
