Tolerates the simultaneous failure of two drives without data loss.
Ensure you are using a key for SAAP 2.0 . Keys for older P410i controllers (SAAP 1.0) will not work on the P420i.
Without the license, the P420i can only process parity for single-drive failure tolerance (RAID 5). The license enables the RAID 6 algorithms, which compute dual parity. This allows the array to survive the simultaneous failure of two physical drives—a critical requirement for large-capacity arrays where rebuild times are lengthy, and the probability of a second drive failure during reconstruction is statistically significant. hp smart array p420i license key
This article dives deep into everything you need to know about the —what it is, why you need it, where to find it, and the best strategies for managing it in 2025 and beyond.
A: No. The ProLiant drivers (hpsa/hpsa-linux) are proprietary. The license check is hardcoded into the controller's onboard ROM. You cannot hack it. Tolerates the simultaneous failure of two drives without
Before applying a license key to your HP Smart Array P420i, ensure your system meets these critical hardware baselines:
Even without a license, a minimum of 512MB Flash Backed Write Cache (FBWC) is required to enable RAID 5, 50, 6, and 60. How to Install a License Key Without the license, the P420i can only process
